Star 14. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. The route configuration allows applying CORS directly to a route as metadata with key cors. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted This is the number of tokens the token bucket can hold. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. Oracle Cloud Infrastructure SDK for TypeScript and JavaScript API Reference - 2.53.1. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. The predicates defined by RouteDefinitionLocator beans are combined using logical and. Once a request has been marked as routed, other routing filters will not route the request again, This section covers common problems that may arise when you use Spring Cloud Gateway. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? NEVER_STRIP: The version is not stripped, even if the original request path contains no version. AddResponseHeader is aware of URI variables used to match a path or host. The arguments are typically listed in the order that are needed for the shortcut configuration. status codes you want to trip the circuit breaker you can either use an integer with the status code Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Most examples below use the shortcut way. The following example configures a RewriteResponseHeader GatewayFilter: For a header value of /42?user=ford&password=omg!what&flag=true, it is set to /42?user=ford&password=***&flag=true after making the downstream request. It is possible to create a gateway filter named without the. backoff: The configured exponential backoff for the retries. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. By clicking Sign up for GitHub, you agree to our terms of service and The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int). The args key is a map of key value pairs to configure the predicate or filter. The following two examples are equivalent: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. Displays the list of routes defined in the gateway. The filter takes a host parameter. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. The pattern is an Ant-style pattern with . For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. The following listing configures a RewritePath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. Any otherway is there apart from blocking call? XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. API gateway provides a unified access for services in microservices architecture. In configuration, you can reference the bean by name using SpEL. NOTE: This is not recommended for production. GitHub spring-cloud / spring-cloud-gateway Public Notifications Fork 2.9k Star 3.9k Code Issues 337 Pull requests 39 Actions Projects Security Insights New issue How to modify spring cloud gateway response headers #1092 Closed Spring cloud gateway response body modification. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. As a result, you can inject request headers and query parameters, for instance, and you can constrain the incoming requests with declarations in the mapping annotation. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. To provide the same CORS configuration to requests that are not handled by some gateway route predicate, set the spring.cloud.gateway.globalcors.add-to-simple-url-handler-mapping property to true. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. Additionally, to set a multi-valued header, use the header name multiple times like AddRequestHeadersIfNotPresent=X-Request-Color-1:blue,X-Request-Color-1:green. The RequestRateLimiter is not configurable with the "shortcut" notation. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. The RemoveRequestParameter GatewayFilter factory takes a name parameter. When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. let's see. This predicate matches cookies that have the given name and whose values match the regular expression. It offers a simple way to manipulate the request path by allowing templated segments of the path. If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. However, there is one in another application, registered under localhost:9994. The following example configures an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. There is an abstract class called AbstractRoutePredicateFactory which you can extend. See the documentation for @RequestMapping in Spring MVC for more details of those features. It uses the Host header, scheme, port and path of the current request to create the various headers. In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. Closing due to lack of requested feedback. Add a response header named X-Request-Foo with a value of Bar to the original response. The lowercase full name of the secure header needs to be used to disable it.. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. This uses Java regular expressions for a flexible way to rewrite the request path. The following example below is invalid: The Redis implementation is based on work done at Stripe. The following example configures a SaveSession GatewayFilter: If you integrate Spring Security with Spring Session and want to ensure security details have been forwarded to the remote process, this is critical. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. It uses Java regular expressions for a flexible way to rewrite the response header value. This handler runs the request through a filter chain that is specific to the request. @ryanjbaxter thanks, the core code is a filter https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt ,but it can't modify header in a post filter,is it a right way writing like this? This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. To write a custom global filter, you must implement GlobalFilter interface as a bean. For example, you might want to extract the trailing elements of a path to pass them downstream: All the features of Spring MVC and Webflux are available to gateway handler methods. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. SpringCloud Gateway After Before Between Cookie Header Host Method Path Query RemoteAddr Weight 5.1 Path spring: application: name: gateway-server cloud: gateway: routes: - id: aaa uri: http://localhost:8001 predicates: - Path=/product/** - id: bbb uri: http://localhost:8002 predicates: - Path=/order/** 5.2 Query This vulnerability is known as HTTP Response Splitting. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean Spring Cloud Gateway includes many built-in GatewayFilter Factories. The LocalResponseCache runs if its associated property is enabled (spring.cloud.gateway.filter.local-response-cache.enabled) and activates a local cache using Caffeine for all responses that meet the following criteria: The response has one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. forwards the incoming token to outgoing resource requests. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. Value 3.9. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. CircuitBreaker also supports URI variables in the fallbackUri. A route is matched if the aggregate predicate is true. return r.host("*.somehost.org").and().path("/somepath") You can use the CacheRequestBody filter to cache the request body before sending it downstream and getting the body from exchange attribute. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. Here is a link to someone asking about ordered filters that may provide more insight: #1341. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute. Like in the case of global configuration, the properties belong to Spring Framework CorsConfiguration. This filter also automatically calculates the. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. the ID of the service from the DiscoveryClient. In In configuration, reference the bean by name using SpEL. Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). URI variables may be used in the value and are expanded at runtime. .uri("http://someuri") Otherwise, the original value in the client request is sent. Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. The ServerHttpResponse instance is used to . If youre using load-balanced routes, you need to explicitly define your. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. httpStatusCode: The HTTP Status of the request returned to the client. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. This predicate matches requests that happen before the specified datetime. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. Well occasionally send you account related emails. It is a Spring Boot application with Spring Cloud stuff that can make it sit between clients and their requests and multiple services, where it offers features such as predicates for shaping. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). The preceding route matches if the request contained a red query parameter whose value matched the gree. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. }) By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. For example, you can match on the path segment of the URL or the HTTP method of the request. The following listing configures a SetRequestHostHeader GatewayFilter: The SetRequestHostHeader GatewayFilter factory replaces the value of the host header with example.org. This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. The maxSize is a DataSize type, so values can be defined as a number followed by an optional DataUnit suffix such as 'KB' or 'MB'. This predicate extracts the URI template variables (such as segment, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. The following listing shows how to cache the request body GatewayFilter: CacheRequestBody extracts the request body and converts it to a body class (such as java.lang.String, defined in the preceding example). The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. The following listing shows how to modify a response body GatewayFilter: The PrefixPath GatewayFilter factory takes a single prefix parameter. AddRequestHeader is aware of the URI variables used to match a path or host. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). The PreserveHostHeader GatewayFilter factory has no parameters. The following example configures a PreserveHostHeader GatewayFilter: The RedirectTo GatewayFilter factory takes two parameters, status and url. name can contain a space-separated list of header names. Embed. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. .route("test1", r -> { keyResolver is a bean that implements the KeyResolver interface. This filter sets a request attribute that the routing filter inspects to determine if the original host header should be sent rather than the host header determined by the HTTP client. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. From the drop down, choose Mapping template and copy and paste the mapping template text below into the Template input box. The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. This predicates matches the Host header that matches the pattern. To configure per-route timeouts: This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. This is the number of tokens taken from the bucket for each request and defaults to 1. When a request is made through the gateway to /json/hello, the request is transformed by using the definition provided in hello.proto, sent to com.example.grpcserver.hello.HelloService/hello, and the response back is transformed to JSON. In the next tutorial of Spring Cloud Gateway Example we will implement these theories and build an application with microservice architecture using Spring Cloud Gateway and demonstrate working examples on web filters to modify request and response body. Retrieving Information about a Particular Route, 15.6. Already on GitHub? It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. This predicate extracts the URI template variables (such as sub, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. All pre filter logic is executed. In addition, through the spring.cloud.gateway.metrics.tags.path.enabled property (by default, false), you can activate an extra metric with the path tag: These metrics are then available to be scraped from /actuator/metrics/spring.cloud.gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. This paper will introduce its usage in detail. Currently, only forward: schemed URIs are supported. Displays information about a particular route. For example, given a Gateway that has 1 replica, the following will . Easy to extend and/or customize using standard Spring patterns The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled GitHub Gist: instantly share code, notes, and snippets. Policy to specify how to modify the response code, body and headers. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. By default, it creates a NettyChannel by using the default TrustManagerFactory. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). Sign in The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. There are many caching cases on the network, but there are various Bug problems in the testing process. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. 1. Those values are then available for use by GatewayFilter factories. reverse proxies. Displays the list of GatewayFilter factories applied to a particular route. }, 4. 2016-10-05: 4.3: CVE-2016-6426 CISCO Called the mutate methods as below: ServerHttpRequest request = exchange.getRequest () .mutate () .header ("headerkey", jwt) .build (); exchange.mutate ().request (request).build (); return chain.filter (exchange); However, the header is not injected to the backend api. If none of these parameters are configured but the global filter is enabled, by default, it configures 5 minutes of time to live for the cached response. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. The following example configures a header route predicate: This route matches if the request has a header named X-Request-Id whose value matches the \d+ regular expression (that is, it has a value of one or more digits). The Between route predicate factory takes two parameters, datetime1 and datetime2 This is the value of the Location header. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. When setting the The AddRequestHeader GatewayFilter factory takes a name and value parameter. The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. Each item defines the name and the arguments of a given predicate. /resource). This can be used with reverse proxies such as load balancers or web application firewalls where ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. This predicate matches with a header that has the given name whose value matches the regular expression. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. For the external controller/handler scenario, headers can be added with exception details. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. Spring Cloud Zuul is one of the core components of Spring Cloud Netflix subproject. Gunzenhausen (German pronunciation: [ntsnhazn] (); Bavarian: Gunzenhausn) is a town in the Weienburg-Gunzenhausen district, in Bavaria, Germany.It is situated on the river Altmhl, 19 kilometres (12 mi) northwest of Weienburg in Bayern, and 45 kilometres (28 mi) southwest of Nuremberg.Gunzenhausen is a nationally recognized recreation area. method: Method name in the service that handles the request. This lets you match on anything from the HTTP request, such as headers or parameters. Creating and Deleting a Particular Route, 15.8. Creating of individual headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-enabled, spring.cloud.gateway.x-forwarded.host-enabled, spring.cloud.gateway.x-forwarded.port-enabled, spring.cloud.gateway.x-forwarded.proto-enabled, spring.cloud.gateway.x-forwarded.prefix-enabled. A number of timeouts are associated with this handshake. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). This could be useful for maintenance windows. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. So a request to /hello is sent to /mypath/hello. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. It runs after all other filters have completed and writes the proxy response back to the gateway client response. It seems the response header cannot be modifed in post filter,the following is my code,please tell me a way to solve this problem. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. It is the name of the query parameter to be removed. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. Generally, it will put the identity information into the request header and will not modify the content of the request and response. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. This is of particular use when using something like Spring Session with a lazy data store, and you need to ensure the session state has been saved before making the forwarded call. Zuul profile. Feign is a great way to communicate between services and send data like a JSON request body, single header or multiple headers and much more. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. For each global filter, there is a string representation of the filter object (for example, org.spring[emailprotected]77856cc5) and the corresponding order in the filter chain. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. .
