In configuration, you can reference the bean by name using SpEL. The errorHeaderName parameter sets the name of the response header containing an error message, by default it is "errorMessage". The Host route predicate factory takes one parameter: a list of host name patterns. Policy to specify how to modify the response code, body and headers. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. The input type is a Spring Framework ServerWebExchange. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. connect-timeout must be specified in milliseconds. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. forwards the incoming token to outgoing resource requests. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. The RemoveRequestHeader GatewayFilter factory takes a name parameter. After the proxy request is made, the post filter logic is run. It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. 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. the request should only be allowed if it comes from a trusted list of IP addresses used by those 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. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. To configure per-route timeouts: It uses the Host header, scheme, port and path of the current request to create the various headers. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). It can be used as API gateway in microservice architecture and supports dynamic routing and filtering functions. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. 3,AddResponseHeader GatewayFilter Factory. You can add headers to the downstream response by using the header() methods on ProxyExchange. status codes that if returned will cause the circuit breaker to be tripped. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. However, there is one in another application, registered under localhost:9994. 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. 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. status: The HTTP status of the request returned to the client. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. return r.host("*.somehost.org").and().path("/somepath") .uri("http://someuri") AddResponseHeader is aware of URI variables used to match a path or host. 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. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter that uses the optional last parameter: This removes attributes "id" and "color" from the JSON content body at any level. 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. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. 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. If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. application.yml. outcome: The outcome, as classified by HttpStatus.Series. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. Spring Cloud Gateway includes many built-in route predicate factories. I suppose your issue may have been different than mine, but when I turned on trace logging I saw that my filter was executing after the response was sent and so I gave the filter a different order value that put it in the right order. 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. The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). NEVER_STRIP: The version is not stripped, even if the original request path contains no version. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in If it is not provided, the value of the Host request header is used. Want to remove the "warning cannot modify header information" error from your WordPress website? The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. The request returns a 200 without a response body. By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. Standard policies to change default 3scale APIcast behavior 3scale provides built-in, standard policies that are units of functionality that modify how APIcast processes requests and responses. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. For example, you can match on the path segment of the URL or the HTTP method of the request. A per-route response-timeout with a negative value will disable the global response-timeout value. You can overwrite the names of the headers in the configuration by setting the values of the following arguments (shown with their default values): executionExceptionTypeHeaderName ("Execution-Exception-Type"), executionExceptionMessageHeaderName ("Execution-Exception-Message"), rootCauseExceptionTypeHeaderName ("Root-Cause-Exception-Type"), rootCauseExceptionMessageHeaderName ("Root-Cause-Exception-Message"). To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. CircuitBreaker also supports URI variables in the fallbackUri. Appending multiple headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-append, spring.cloud.gateway.x-forwarded.host-append, spring.cloud.gateway.x-forwarded.port-append, spring.cloud.gateway.x-forwarded.proto-append, spring.cloud.gateway.x-forwarded.prefix-append. Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. This metric will be available from /actuator/metrics/spring.cloud.gateway.routes.count. 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. The following example below is invalid: The Redis implementation is based on work done at Stripe. This property takes a list of filters. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. This vulnerability is known as HTTP Response Splitting. Post global filters are usually used in spring cloud gateway to perform operations on response like adding some headers or modifying response body or response status etc. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. Multiple matching segments are allowed. The ServerHttpResponse instance is used to . The RequestHeaderSize GatewayFilter factory takes maxSize and errorHeaderName parameters. If the information is not provided within the next 7 days this issue will be closed. 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. 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. The RequestRateLimiter is not configurable with the "shortcut" notation. 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. Acompanhe-nos: can gabapentin help with bell's palsy Facebook 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 algorithm used is the Token Bucket Algorithm. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. All. Tripping The Circuit Breaker On Status Codes, 12.4.1. These are special filters that are conditionally applied to all routes. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. Spring cloud gateway response body modification. So, if the downstream server responded with X-Request-Red:1234, it will be replaced with X-Request-Red:Blue, which is what the downstream service would receive. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. 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. For example, to reference a filter named Something in configuration files, the filter privacy statement. Let's simplify this scenario. The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. 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. The collection of filters applied to the route. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. URI variables may be used in the value and are expanded at runtime. Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. backoff: The configured exponential backoff for the retries. AddRequestHeadersIfNotPresent also supports URI variables used to match a path or host. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. It uses Java regular expressions for a flexible way to rewrite the response header value. Easy to extend and/or customize using standard Spring patterns A burst of 20 is allowed, but, in the next second, only 10 requests are available. The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. The arguments are typically listed in the order that are needed for the shortcut configuration. In future milestone releases, there will be some KeyResolver implementations. The RemoveResponseHeader GatewayFilter factory takes a name parameter. The route configuration allows applying CORS directly to a route as metadata with key cors. The following table below summarizes the Spring Cloud Gateway actuator endpoints (note that each endpoint has /actuator/gateway as the base-path): Displays the list of global filters applied to the routes. This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. if. URI variables may be used in the value and are expanded at runtime. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. name can contain a space-separated list of header names. 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. The following listing shows how to modify a request body GatewayFilter: You can use the ModifyResponseBody filter to modify the response body before it is sent back to the client. This predicate matches requests that happen after datetime1 and before datetime2. Looking for a place to stay in Gunzenhausen? You can configure Spring Cloud Gateway for Kubernetes to run multiple instances in High Availability as you would do with a normal Kubernetes resource. Modifying the request body is a common requirement. You can extend an abstract class called AbstractGatewayFilterFactory. . The circuit breaker config object takes a list of You must use $\ to mean $ because of the YAML specification. Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. It must be a valid Spring HttpStatus. It does not work in a traditional Servlet Container or when built as a WAR. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] The default list of headers that is removed comes from the IETF. Modify request body. You can also manipulate response headers (and anything else you like in the response) by adding a mapper to the get() method (and other methods). If the new named header already exists, its values are augmented with the new values. The XForwarded Remote Addr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). This can be used with reverse proxies such as load balancers or web application firewalls where The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. To add this functionality to the gateway, you need to add the TokenRelayGatewayFilterFactory like this: and it will (in addition to logging the user in and grabbing a token) If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. The gateway maintains a client pool that it uses to route to backends. Most examples below use the shortcut way. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium Naming Custom Filters And References In Configuration, 18. This predicate matches requests that happen before the specified datetime. The pattern is an Ant-style pattern with . This type of Repository is not suited to populate Routes across multiple Gateway instances. There are many caching cases on the network, but there are various Bug problems in the testing process. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. 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. Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. 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. Raw. The lowercase full name of the secure header needs to be used to disable it.. 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. A number of timeouts are associated with this handshake. 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. It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. It is the name of the header to be removed. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. 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 following listing configures a RewritePath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. The gateway can listen for requests on HTTPS by following the usual Spring server configuration. This uses Java regular expressions for a flexible way to rewrite the request path. This paper will introduce its usage in detail. AddRequestParameter is aware of the URI variables used to match a path or host. value or the String representation of the HttpStatus enumeration. Spring Cloud Gateway includes many built-in GatewayFilter Factories. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. You can read more about them in the. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. 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; . 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). The following describes an alternative style gateway. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. 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). The following listing configures a RequestSize GatewayFilter: The RequestSize GatewayFilter factory sets the response status as 413 Payload Too Large with an additional header errorMessage when the request is rejected due to size. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. *) and the replacement /${remaining}. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. Closing due to lack of requested feedback. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. That is not a complete working sample, it is just some code. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. It must be a Java System Property, not a Spring Boot property. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. The following example configures a PreserveHostHeader GatewayFilter: The RedirectTo GatewayFilter factory takes two parameters, status and url. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. .metadata(RESPONSE_TIMEOUT_ATTR, 200) 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 Currently, only forward: schemed URIs are supported. Properties. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. A utility method (called get) is available to make access to these variables easier. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters.
