UnknownHostException возникает при вызове URL-адреса ресурса с помощью RouteLocatorBuilder

Я должен использовать spring-cloud-gateway. У меня возникли проблемы с настройкой простого проекта с весенней загрузкой из этого руководства https://spring.io/guides/gs/gateway/

@SpringBootApplication
@RestController
public class MarouteApplication {

    @Bean
    public RouteLocator maRoute(RouteLocatorBuilder builder) {
        return builder.routes()
                .route(p -> p
                        .path("/get")
                        .filters(f -> f.addRequestHeader("Hello", "World"))
                        .uri("http://httpbin.org:80"))
                .route(p -> p
                        .path("/bling")
                        .uri("http://localhost:9090/test"))
                .build();
    }

    @GetMapping(value = "/test")
    public ResponseEntity<String> getPerso() throws Exception {
        return ResponseEntity.ok("{\"value\":\"OK\"}");
    }

    public static void main(String[] args) {
        SpringApplication.run(MarouteApplication.class, args);
    }

}

Итак у меня три маршрута, два настроены через RouteLocatorBuilder. И один настроил через application.yaml.

Конечная точка http://localhost:9090/test работает.

Для маршрута /get я получил:

Я получил ту же ошибку для маршрута /foo:

И для маршрута /bling я получил ошибку кода 413 (запрос объекта слишком велик)

Я подозреваю, что мой прокси не разрешает внешние сайты, поэтому я настраиваю его в application.yaml. Результат не меняется.

Если у кого-нибудь есть идеи

httpbin.org:80 работает в вашем браузере?   -  person Kalpesh Soni    schedule 09.09.2019

Привет, спасибо за ваш ответ. Да, это работает в моем браузере. Я попробовал другие конечные точки этого сайта в своем проекте и в своем браузере, и он тоже работает.   -  person Benjamin    schedule 10.09.2019

Поэтому я не могу получить доступ к внешним веб-сайтам из-за моей профессиональной среды, которая не позволяет этого. На других компьютерах (например, на моем личном) это работает.

Маршрут работает, если я перенаправляюсь на другую локальную конечную точку. Вы не можете перенаправить на ту же конечную точку порта, которая объясняет ошибку 413. Поэтому я запустил новый API на другом порту, и он работает. Важно знать, что для этого маршрута:

    @Bean
    public RouteLocator maRoute(RouteLocatorBuilder builder) {
        return builder.routes()
                .route(p -> p
                        .path("/foo")
                        .uri("http://localhost:8080/test"))
                .build();
    }

Маршрут перенаправляется на http://localhost:8080/foo. Поэтому, если у вас нет конечной точки в http:localhost: 8080/foo у вас будет 404. Вы можете использовать множество способов перенаправления на 8080/test, например:

    @Bean
    public RouteLocator maRoute(RouteLocatorBuilder builder) {
        return builder.routes()
                .route(p -> p
                        .path("/test")
                        .uri("http://localhost:8080"))
                .build();
    }

или если вы хотите сохранить перенаправление с конечной точкой /foo

    @Bean
    public RouteLocator maRoute(RouteLocatorBuilder builder) {
        return builder.routes()
                .route(p -> p
                        .path("/foo")
                        .filters(f -> f.rewritePath("/foo", "/test"))
                        .uri("http://localhost:8080"))
                .build();
    }

Кроме того, если вы хотите знать, перенаправляет ли ваш маршрут то, что вы действительно ожидаете, вы можете настроить уровень ведения журнала в вашем application.yaml или свойствах:

logging:
  level:
    org.springframework.cloud.gateway: TRACE
    org.springframework.http.server.reactive: DEBUG
    org.springframework.web.reactive: DEBUG
    reactor.ipc.netty: DEBUG
    reactor.netty: DEBUG
