如何从服务器获取标头？改造2

Question

当我登录到我的服务器时，我应该使用＆＃34; x-auth-token＆＃34;但我不知道怎么做？

在Java中它只是：

token = urlConnection.getHeaderField（＆＃34; x-auth-token＆＃34;）;

我已经尝试过了：

LoginService loginService = ServiceGenerator.createService(LoginService.class,loginEmail,loginPassword);
                Call<User> call = loginService.basicLogin();
                call.enqueue(new Callback<User>() {


                    @Override
                    public void onResponse(Call<User> call, Response<User> response) {


                        okhttp3.Headers headers = response.headers();
                        String token = response.headers().get("x-auth-token");
                        Log.e(LOG_TAG, "My token is" + token);



                            Toast.makeText(getApplicationContext(),"You have been logged", Toast.LENGTH_SHORT).show();

之后我得到了回复，我的x-auth-token = null;
