Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. Easy to extend and/or customize using standard Spring patterns if you intend to modify a JSON response body prior to returning to the client, the above gist will not work (i know because i tried). 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. exceptions: A list of thrown exceptions that should be retried. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. 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. . Properties. The Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. method: Method name in the service that handles the request. The gateway maintains a client pool that it uses to route to backends. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. 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. privacy statement. The RemoteAddr Route Predicate Factory, 5.10.1. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. Those values are then available for use by GatewayFilter factories. if. 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. When setting the The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. 1. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. 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. Route: The basic building block of the gateway. To disable it, set the following property: This will default to true in a future release. responseCode; responseHeaderTransformations; responseMessage; type; . The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. 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) 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. backoff: The configured exponential backoff for the retries. This filter (which configures the local response cache per route) is available only if the local response global cache is enabled. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. This paper will introduce its usage in detail. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. The default list of headers that is removed comes from the IETF. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. 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. 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. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. 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. 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. Like in the case of global configuration, the properties belong to Spring Framework CorsConfiguration. Each item defines the name and the arguments of a given predicate. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. outcome: The outcome, as classified by HttpStatus.Series. httpStatusCode: The HTTP Status of the request returned to the client. Route filters are scoped to a particular route. So a request to /hello is sent to /mypath/hello. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. 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. Those values are then available for use by GatewayFilter factories. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. The url parameter should be a valid URL. 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. Cleanliness 4.4. It is the permissible size limit of the request defined in bytes. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter: This listing adds 2 headers X-Request-Color-1:blue and X-Request-Color-2:green to the downstream requests headers for all matching requests. Have a question about this project? By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. to the exchange attributes. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. Any otherway is there apart from blocking call? See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. The filter takes a host parameter. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). The pile of explanations in front of Xinchen still don . It accepts the first parameter to override the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours) and a second parameter to set the maximum size of the cache to evict entries for this route (KB, MB, or GB). This vulnerability is known as HTTP Response Splitting. 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. 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). The following example configures CORS: In the preceding example, CORS requests are allowed from requests that originate from docs.spring.io for all GET requested paths. It is the name of the header to be removed. URI variables may be used in the value and will be expanded at runtime. 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. return routeBuilder.routes() This predicate matches cookies that have the given name and whose values match the regular expression. Because Spring-Cloud-Gateway is a responsive architecture design based on WebFlux, traditional programming ideas are not suitable for the development of Reactor Stream in the process of migrating from Zuul. .filters(f -> f.addRequestHeader("header1", "header-value-1")) 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. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. This could be useful for maintenance windows. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. Note that the $ should be replaced with $\ because of the YAML specification. In configuration, reference the bean by name using SpEL. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. You can read more about them in the. GatewaySampleApplication.java. Service 4.3. The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. 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 preceding route matches if the request contained a red query parameter whose value matched the gree. The weights are calculated per group. value or the String representation of the HttpStatus enumeration. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. This strips the service ID from the path before the request is sent downstream. response-timeout must be specified as a java.time.Duration. 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. Modifying the Way Remote Addresses Are Resolved, 5.12. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. This predicates matches the Host header that matches the pattern. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. You can configure the logging system to have a separate access log file. as the separator. it is proxying. If youre using load-balanced routes, you need to explicitly define your. This applies the filter to all requests. Here is a link to someone asking about ordered filters that may provide more insight: #1341. 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. If it is not provided, the value of the Host request header is used. Both offer the same possibilities. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). Retrieving Information about a Particular Route, 15.6. In some cases you might want to trip a circuit breaker based on the status code 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. This predicate matches requests that happen after the specified datetime. After the proxy request is made, the post filter logic is run. You signed in with another tab or window. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. 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. It adds the Host header, scheme and port of the current request to any existing Forwarded header. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. 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. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. 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. also note that the gist doesn't take the decoders into account from upstream like here. Since the request can be read only once, we need to cache the request body. The methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. This interface and its usage are subject to change in future milestone releases. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. All of these predicates match on different attributes of the HTTP request. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. Zuul profile. AddResponseHeader is aware of URI variables used to match a path or host. 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.) 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 value of the Location header. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. 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 following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. Generally, it will put the identity information into the request header and will not modify the content of the request and response. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. 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). SetRequestHeader is aware of URI variables used to match a path or host. Displays information about a particular route. Predicate: This is a Java 8 Function Predicate. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. the request should only be allowed if it comes from a trusted list of IP addresses used by those This is the rate at which the token bucket is filled. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? The default request size is set to five MB if not provided as a filter argument in the route definition. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. This handler runs the request through a filter chain that is specific to the request. pass the authentication token downstream to the services (in this case I got the root cause. Embed. That is not a complete working sample, it is just some code. If the response is already cached and a new request is performed with no-cache value in Cache-Control header, it returns a bodiless response with 304 (Not Modified). There are many caching cases on the network, but there are various Bug problems in the testing process. It uses the Host header, scheme, port and path of the current request to create the various headers. It offers a simple way to manipulate the request path by allowing templated segments of the path. This filter works only with HTTP (including HTTPS) requests. In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. 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. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. to your account, I am trying to modify a header of response in a post filter of gateway,the filter handle a cors problem which would filt websockt service ,the websockt service is a micro-service which must been decorated with cors configurationso a websockt request will get a response with multiple header like Access-Control-Allow-Origin, to solve this questioni must modify the response header of the key Access-Control-Allow-OriginHowever ,when i do this, a error occured, java.lang.UnsupportedOperationException: null at org.springframework.http.ReadOnlyHttpHeaders.set(ReadOnlyHttpHeaders.java:99) ~[spring-web-5.1.6.RELEASE.jar:5.1.6.RELEASE] at com.apigw.filter.CORSFilter.lambda$filter$0(CORSFilter.java:84) ~[classes/:na] at reactor.core.publisher.MonoRunnable.call(MonoRunnable.java:73) ~[reactor-core-3.2.8.RELEASE.jar:3.2.8.RELEASE]. The reason the filters are divided by the dotted line is that filters can run logic both before and after the proxy request is sent. regexp, so green and greet would match. For a full working sample see this project. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. To clear the routes cache, make a POST request to /actuator/gateway/refresh. Since 4.0.0, Spring Cloud Gateway supports Spring AOT transformations and native images. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. This filter can be configured only by using the Java DSL. 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. 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. The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. Want to remove the "warning cannot modify header information" error from your WordPress website? forwards the incoming token to outgoing resource requests. The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. The route configuration allows applying CORS directly to a route as metadata with key cors. The ServerHttpResponse instance is used to . The KeyResolver is a simple one that gets the user request parameter By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. For the external controller/handler scenario, headers can be added with exception details. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). 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. This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. Easy to extend and/or customize using standard Spring patterns If the fallback is called, the request is forwarded to the controller matched by the URI. If the information is not provided within the next 7 days this issue will be closed. The AddRequestHeader GatewayFilter factory takes a name and value parameter. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). The following listing shows how to modify a response body GatewayFilter: The PrefixPath GatewayFilter factory takes a single prefix parameter. response Header Transformations: . Spring Cloud Gateway offers two RouteDefinitionRepository implementations. Policy to specify how to modify the response code, body and headers. The gateway can listen for requests on HTTPS by following the usual Spring server configuration. Spring Cloud Gateway includes many built-in route predicate factories. . Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean 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. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. There are convenience methods that you can use to mark an exchange as routed Currently, only forward: schemed URIs are supported. aws api gateway parameter mapping. @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 uses Java regular expressions for a flexible way to rewrite the request path. This can be used with reverse proxies such as load balancers or web application firewalls where httpMethod: The HTTP method used for the request. Most examples below use the shortcut way. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. status codes you want to trip the circuit breaker you can either use an integer with the status code public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ URI variables may be used in the value and are expanded at runtime. Displays the list of GatewayFilter factories applied to a particular route. 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.) cloudflare tunnel home assistant 19 3407 . 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). 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 following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. Star 14. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. 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. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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).
