更新POST请求W/Basic HTTP身份验证：“无法重试流式HTTP正文”

Question

@POST("/rest/v1/auth/login")
LoginResponse login(@Body LoginRequest loginRequest);

    @Provides
    @Singleton
    public Client providesClient() {
        OkHttpClient httpClient = new OkHttpClient();

        httpClient.setAuthenticator(new OkAuthenticator() {
            @Override
            public Credential authenticate(Proxy proxy, URL url, List<Challenge> challenges) throws IOException {
                return getCredential();
            }

            @Override
            public Credential authenticateProxy(Proxy proxy, URL url, List<Challenge> challenges) throws IOException {
                return getCredential();
            }
        });

        return new OkClient(httpClient);
    }

1. 所以我必须发送信息。
2. 正在获取身份验证质询请求。
3. 正在响应质询请求。
4. 试图重新发送请求，然后引发错误。

不知道怎么绕过这个。任何帮助都会很好。

谢了，杰西。

以防万一，下面是我为基本Auth所做的代码。

首先，MyApplication类中的init：

ApiRequestInterceptor requestInterceptor = new ApiRequestInterceptor();
requestInterceptor.setUser(user); // I pass the user from my model

ApiService apiService = new RestAdapter.Builder()
            .setRequestInterceptor(requestInterceptor)
            .setServer(Constants.API_BASE_URL)
            .setClient(new OkClient()) // The default client didn't handle well responses like 401
            .build()
            .create(ApiService.class);

import android.util.Base64;
import retrofit.RequestInterceptor;

/**
 * Interceptor used to authorize requests.
 */
public class ApiRequestInterceptor implements RequestInterceptor {

    private User user;

    @Override
    public void intercept(RequestFacade requestFacade) {

        if (user != null) {
            final String authorizationValue = encodeCredentialsForBasicAuthorization();
            requestFacade.addHeader("Authorization", authorizationValue);
        }
    }

    private String encodeCredentialsForBasicAuthorization() {
        final String userAndPassword = user.getUsername() + ":" + user.getPassword();
        return "Basic " + Base64.encodeToString(userAndPassword.getBytes(), Base64.NO_WRAP);
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}
