Connection time out when running Micronaut behind corporate proxy #1611

Closed 3logy closed 5 years ago

3logy commented 5 years ago

When i run/test a micronaut application behind a corporate proxy, using cntlm or not, it occurs the following error :

"Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information: test.api.corporateurl.net/{proxyHost}:{proxyPort}"

I posted a question on Stackoverflow and set the proxy like the documentation said, but it seems like micronaut while requesting append the proxy at the end of the client root url.

I can test and request with the same complete url on postman (using system proxy) and its works.

`

  @MicronautTest
  public class DataControllerTest {

         @Client("https://test.api.corporateurl.net/api/v1/data/")
         @Inject RxHttpClient httpClient;

         @Test
         public void testFetchData() throws Exception {
               Map<String, Object> pathVariableMap = new HashMap<>();
               pathVariableMap.put("param1", "parametervariable");

               String uri = UriBuilder.of("/{param1}/")
                                .expand(pathVariableMap)
                               .toString();

               assertEquals("/parametervariable", uri);

               String result = httpClient.toBlocking().retrieve(uri);
               System.out.println(result);
          }  
}

The stack over flow answer relates to the CLI, for the HTTP client you need to configure the proxy settings through the HttpClientConfiguration settings in application.yml

@graemerocher` thank you. it's work.

I set it for example like this :

` myclient:

    client:

          proxy-address: xx.xx.xx.xx:2222

          proxy-type: HTTP

`
