response = 0，通过Retrofit

Im试着做POST Retrofit响应，但我必须从这个响应中获取数据。在栈tace中，我看到请求正常，代码== 200，但响应= 0.但是这个请求必须向我提供数据，我从邮递员服务中检查了这个数据。我如何从我的请求中获取数据？response = 0，通过Retrofit

与片段和结果堆栈跟踪从邮差：从邮差

你应该检查你的JSON的结构就像在你的主要对象有2个JSON对象和状态布尔值。这意味着您的主对象包含2个模型（一个是用户，另一个是auth）和布尔值。

谢谢，但我怎么能，例如，我的应用程序的状态和代码？ –

SignInResult包含状态和代码字段。 –

您试图从响应主体中解析SignInResults对象。但看着邮差回应，这与此无关。

您必须分析相应的对象：

    "auth": { 
     "token": "12f6d4123b9947e79f37a4c415bb4b51", 
     "expires": "2017-04-26 10:38:05", 
     "user_id": "11272862" 
    }, 
    "user": { 
     "user_id": "11272862",
