在microprofile rest客户端中设置基本auth

Question

    MyService client = RestClientBuilder.newBuilder()
        .baseUri(URI.create("https://localhost:8080"))
        .build(MyService.class);

还应该提到的是，我尝试了@Provider过滤器来设置头部，但我似乎不知道如何使用该方法只针对单个REST客户机，我有几个。

那么：如何使用microprofile rest客户机在不影响Jax-Rs接口本身的情况下设置基本身份验证呢？

Answer 1

您应该能够在MyService上使用@clientheaderparam注释。类似于：

@Path("/my")
@ClientHeaderParam(name = "Authorization", value = "{lookupAuth}")
public interface MyService {

  default String lookupAuth() {
    return "Basic " + 
         Base64.getEncoder().encodeToString("someuser:somepass".getBytes());
  }
}

如果不可能修改接口，您有两个选项：

null

@ClientHeaderParam(name = "Authorization", value = "{lookupAuth}")
public interface MyServiceWrapper extends MyService {
  default String lookupAuth() {
    return "Basic " + Base64.getEncoder().encodeToString("someuser:somepass".getBytes());
  }
}

null

@Priority(Priorities.AUTHENTICATION)
public class BasicRequestFilter implements ClientRequestFilter {
    @Override
    public void filter(ClientRequestContext requestContext) throws IOException {
        requestContext.getHeaders().add(HttpHeaders.AUTHORIZATION, getAccessToken());
    }

    private String getAccessToken() {
        return "Basic " + Base64.getEncoder().encodeToString("someuser:somepass".getBytes());
    }
}

MyService client = RestClientBuilder.newBuilder()
    .register(BasicRequestFilter.class)
    .baseUri(URI.create("https://localhost:8080"))
    .build(MyService.class);
