`SetStatus` 過濾器

SetStatus 過濾器接受一個引數：status。它必須是有效的 Spring HttpStatus。它可以是整數值 404 或該列舉的字串表示：NOT_FOUND。以下程式碼清單配置了一個 SetStatus 過濾器

application.yml

spring:
  cloud:
    gateway:
      mvc:
        routes:
        - id: setstatusstring_route
          uri: https://example.org
          predicates:
          - Path=/path1
          filters:
          - SetStatus=UNAUTHORIZED
        - id: setstatusint_route
          uri: https://example.org
          predicates:
          - Path=/path2
          filters:
          - SetStatus=401

GatewaySampleApplication.java

import static org.springframework.cloud.gateway.server.mvc.filter.AfterFilterFunctions.setStatus;
import static org.springframework.cloud.gateway.server.mvc.filter.BeforeFilterFunctions.uri;
import static org.springframework.cloud.gateway.server.mvc.handler.GatewayRouterFunctions.route;
import static org.springframework.cloud.gateway.server.mvc.handler.HandlerFunctions.http;

@Configuration
class RouteConfiguration {

    @Bean
    public RouterFunction<ServerResponse> gatewayRouterFunctionsSetStatus() {
        return route("setstatus_route")
                .GET("/path1", http())
                .before(uri("https://example.org"))
                // setStatus("UNAUTHORIZED") works as well
                .after(setStatus(HttpStatus.UNAUTHORIZED))
            .build().and(route("setstatusint_route")
                .before(uri("https://example.org"))
                .GET("/path2", http())
                .after(setStatus("401"))
                .build());
    }
}

在這兩種情況下，響應的 HTTP 狀態碼都設定為 401。
