The following listing configures a RemoveResponseHeader GatewayFilter: This will remove the X-Response-Foo header from the response before it is returned to the gateway client. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. However, you can customize this TrustManager by creating a bean of type GrpcSslConfigurer: This filter allows caching the response body and headers to follow these rules: It caches the response only for one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. The name and argument names are listed as code in the first sentence or two of each section. The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). A route is matched if the aggregate predicate is true. 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. 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. Those values are then available for use by GatewayFilter factories. to the exchange attributes. In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. 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 predicate matches requests that happen before the specified datetime. The body is cached in a request attribute defined by. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. The filter takes a maxSize parameter. By default, it creates a NettyChannel by using the default TrustManagerFactory. First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). If the information is not provided within the next 7 days this issue will be closed. API gateway provides a unified access for services in microservices architecture. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. In order to modify APIcast behavior with custom policies, you must do the following: Add custom policies to APIcast Define a policy chain that configures APIcast policies Add the policy chain to APIcast 4.1. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. *) and the replacement /${remaining}. To enable this, set spring.cloud.gateway.discovery.locator.enabled=true and make sure a DiscoveryClient implementation (such as Netflix Eureka, Consul, or Zookeeper) is on the classpath and enabled. AddRequestHeadersIfNotPresent also supports URI variables used to match a path or host. The status parameter should be a 300 series redirect HTTP code, such as 301. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. name can contain a space-separated list of header names. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). Embed. You can configure the logging system to have a separate access log file. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. A steady rate is accomplished by setting the same value in replenishRate and burstCapacity. You signed in with another tab or window. 4.1. It is the name of the query parameter to be removed. This filter works only with HTTP (including HTTPS) requests. .metadata(RESPONSE_TIMEOUT_ATTR, 200) Raw. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. If the input header does not exist, the filter has no impact. application.yml. 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. URI variables may be used in the value and will be expanded at runtime. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. application.yml. Each item defines the name and the arguments of a given predicate. Let's simplify this scenario. .uri("http://someuri") The request returns a 200 without a response body. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. You can use the CacheRequestBody filter to cache the request body before sending it downstream and getting the body from exchange attribute. Getting the refreshTokenMono is webclient call which is in a different service.. By the time it gives the response, main response is already about to commit and wont allow us to modify the response headers. Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. /resource). #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. pass the authentication token downstream to the services (in this case 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. So, if the downstream server responded with X-Response-Red:1234, it will be replaced with X-Response-Red:Blue, which is what the gateway client would receive. The route configuration allows applying CORS directly to a route as metadata with key cors. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. If the fallback is called, the request is forwarded to the controller matched by the URI. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. GatewaySampleApplication.java. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. However, you can also reroute the request to a controller or handler in an external application, as follows: In this example, there is no fallback endpoint or handler in the gateway application. If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. If it is not provided, the value of the Host request header is used. The following examples show how to set up global pre- and post-filters, respectively: Spring Cloud Gateway provides a utility object called ProxyExchange. Already on GitHub? The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. Spring cloud gateway response body modification. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. extracts an access token from the currently authenticated user, It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. The following example configures a RemoteAddr route predicate: This route matches if the remote address of the request was, for example, 192.168.1.10. You can also define a rate limiter as a bean that implements the RateLimiter interface. The KeyResolver is a simple one that gets the user request parameter The following listing configures a RewriteLocationResponseHeader GatewayFilter: For example, for a request of POST api.example.com/some/object/name, the Location response header value of object-service.prod.example.net/v2/some/object/id is rewritten as api.example.com/some/object/id. or check if an exchange has already been routed. It is the permissible size limit of the request defined in bytes. Spring Cloud supports Resilience4J out of the box. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. There should be no reason why a filter cannot modify a response header. Otherwise, the original value in the client request is sent. Currently, only forward: schemed URIs are supported. Displays the list of routes defined in the gateway. Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . Spring Cloud Gateway || Modify Response Body Using Post Global Filter modify response body of route in spring cloud gateway Hi everyone, have you ever worked with Filters ? We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. 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. You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. This handler runs the request through a filter chain that is specific to the request. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. The routine of modifying the response body with Spring Cloud Gateway is the same as the previous request body; Configure routing and filters through code; . This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. 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. 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. This is the number of tokens taken from the bucket for each request and defaults to 1. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. The first one is the I think i have to go for a blocking call here. The RequestRateLimiter is not configurable with the "shortcut" notation. The following example configures a cookie route predicate factory: This route matches requests that have a cookie named chocolate whose value matches the ch.p regular expression. While a Gateway is running you can use kubectl scale to modify the number of replicas. This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). The following example configures a MapRequestHeader: This adds the X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. Sharing Routes between multiple Gateway instances, 17.1. Oracle Cloud Infrastructure SDK for TypeScript and JavaScript API Reference - 2.53.1. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. For example, setting replenishRate=1, requestedTokens=60, and burstCapacity=60 results in a limit of 1 request/min. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. The following describes an alternative style gateway. You can configure additional parameters for each route by using metadata, as follows: You could acquire all metadata properties from an exchange, as follows: Http timeouts (response and connect) can be configured for all routes and overridden for each specific route. The input type is a Spring Framework ServerWebExchange. This predicate matches requests that happen after the specified datetime. NOTE: This is not recommended for production. URI variables may be used in the value and are expanded at runtime. It uses the Netty HttpClient to make the downstream proxy request. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. This is the number of tokens the token bucket can hold. 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. The most noteworthy thing here is: ServerHttpRequest or HttpMessage interface provides a method to get the request headers HttpHeaders getHeaders(); returns a read-only instance, specifically of type ReadOnlyHttpHeaders, mentioned here more than once I wrote this blog post using Spring Cloud Gateway version Greenwich.SR1. Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. 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. A number of timeouts are associated with this handshake. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium Modifying the request body is a common requirement. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. You can customize the way that the remote address is resolved by setting a custom RemoteAddressResolver. as the separator. The RemoveHopByHop Headers Filter removes headers from forwarded requests. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. return r.host("*.somehost.org").and().path("/somepath") 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. Spring Cloud Gateway includes many built-in GatewayFilter Factories. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. You must use $\ to mean $ because of the YAML specification. . By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. It offers a simple way to manipulate the request path by allowing templated segments of the path. The resulting response is similar to the following: The response contains the details of the global filters that are in place. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. let's see. https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java, @ryanjbaxter it seems a route filter,can i modify a response header in a global post filter,thanks. This route matches if the request has a Host header with a value of www.somehost.org or beta.somehost.org or www.anotherhost.org. 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 is useful when you try to support CORS preflight requests and your route predicate does not evaluate to true because the HTTP method is options. This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. Spring Cloud Gateway - read response body and set response headers Ask Question Asked 1 year, 11 months ago Modified 1 year, 11 months ago Viewed 675 times 0 I want to implement a GatewayFilter that reads the response body and out of this the response code is determined and should then be set afterwards. The 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. The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. There is an abstract class called AbstractRoutePredicateFactory which you can extend. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a . Route filters are scoped to a particular route. The following example configures /actuator/gateway/routes: This feature is enabled by default. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. URI variables may be used in the value and are expanded at runtime. Here, you can modify requests and responses before or after sending the downstream request. AddResponseHeader is aware of URI variables used to match a path or host. Spring Cloud Gateway Response Modification Raw README.md Overview As of this writing, there's a somewhat limited/restrictive means of applying HTTP response transformations/modifications via Spring Cloud Gateway, probably because it needs to accommodate both the Mono and Flux (aka "reactive") models. Displays the list of GatewayFilter factories applied to a particular route. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. .filters(f -> f.addRequestHeader("header1", "header-value-1")) The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. Removes an existing route from the gateway. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. For example, given a Gateway that has 1 replica, the following will . Multiple matching segments are allowed. To include Spring Cloud Gateway in your project, use the starter with a group ID of org.springframework.cloud and an artifact ID of spring-cloud-starter-gateway. By default, if the KeyResolver does not find a key, requests are denied. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean The Reactor Netty HttpClient and HttpServer can have wiretap enabled. @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? For a production deployment, you can configure the gateway with a set of known certificates that it can trust with the following configuration: If the Spring Cloud Gateway is not provisioned with trusted certificates, the default trust store is used (which you can override by setting the javax.net.ssl.trustStore system property). All pre filter logic is executed. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. With MVC, it also supports forwarding to a local handler through the forward() method. }) Spring Cloud Gateway 4.0.3 This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. The following listing configures a SetRequestHostHeader GatewayFilter: The SetRequestHostHeader GatewayFilter factory replaces the value of the host header with example.org. This interface and its usage are subject to change in future milestone releases. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). The preceding route matches if the request contained a red query parameter whose value matched the gree. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. 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). must be in a class named SomethingGatewayFilterFactory. The filter takes the following arguments: This file can be generated using protoc and specifying the --descriptor_set_out flag: service: Fully qualified name of the service that handles the request.
