[英]Spring Cloud Gateway is not finding a route path (404 error)
I am investigating Spring Cloud Gateway as an API gateway solution for a professional application and am running through this tutorial: http://spring.io/guides/gs/gateway/#scratch . 我正在研究Spring Cloud Gateway作为用于专业应用程序的API网关解决方案,并且正在本教程中进行操作: http : //spring.io/guides/gs/gateway/#scratch 。
However I am running into issues I cannot solve. 但是,我遇到了无法解决的问题。
Here is my POM 这是我的POM

and here is the Application.java 这是Application.java
@SpringBootApplication
@RestController
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Bean
public RouteLocator myRoutes(RouteLocatorBuilder builder) {
return builder.routes()
.route(p -> p
.path("/get")
.filters(f -> f.addRequestHeader("Hello", "World"))
.uri("http://httpbin.org:80"))
.build();
}
}
Running this and trying to hit http://localhost:8080/get was giving me a gateway timeout. 运行此命令并尝试访问http:// localhost:8080 / get ,这给了我一个网关超时。 Consulting with someone at work I discovered that I am behind a firewall and needed a proxy.
向工作人员咨询后,我发现自己在防火墙后面,需要代理。 So I modified the Application.java to this:
所以我将Application.java修改为:
@SpringBootApplication
@RestController
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Bean
public RouteLocator myRoutes(RouteLocatorBuilder builder) {
return builder.routes()
.route(p -> p.host("internet.proxy.*****.com").and()
.path("/get")
.filters(f -> f.addRequestHeader("Hello", "World"))
.uri("http://httpbin.org:80"))
.build();
}
Now, I am no longer getting a gateway time out but now I am getting a 404 error. 现在,我不再让网关超时,但现在却遇到404错误。 Here is the output using curl http://localhost:8080/get :
这是使用curl http:// localhost:8080 / get的输出 :
{"timestamp":"2019-01-
16T14:24:12.929+0000","path":"/get","status":404,"error":"Not
Found","message":null}
I am probably missing something simple but I cannot see it. 我可能缺少一些简单的东西,但看不到。
EDIT: according to the tutorial listed above this should be the response I get back: 编辑:根据上面列出的教程,这应该是我得到的响应:
{
"args": {},
"headers": {
"Accept": "*/*",
"Connection": "close",
"Forwarded":
"proto=http;host=\"localhost:8080\";for=\"0:0:0:0:0:0:0:1:56207\"",
"Hello": "World",
"Host": "httpbin.org",
"User-Agent": "curl/7.54.0",
"X-Forwarded-Host": "localhost:8080"
},
"origin": "0:0:0:0:0:0:0:1, 73.68.251.70",
"url": "http://localhost:8080/get"
}
在代码中删除@RestController
You have to set Host
header to "internet.proxy.*****.com". 您必须将
Host
标头设置为“ internet.proxy。*****。com”。
You concatenated Host predicate and Path predicate. 您将主机谓词和路径谓词串联在一起。
curl --header "Host: internet.proxy.test.com" http://localhost:8080/get
