Question

我在平台上拨打特定的网络服务;此Web服务可以返回错误情况，如下所示：

Status: 422 Unprocessable Entity
{
  "message": "Validation Failed",
  "errors": [
    {
      "field": "email",
      "code": "Email",
      "message": "Value of field 'email' must have a valid e-mail format"
    }
  ]
}

在我的回调中，我无法阅读该消息（始终为空！）。但是在我的日志中，我可以看到正确的信息：

01:02:53.295 19015-19371/com.xx D/OkHttp: <-- 422 Unprocessable Entity: https://xxxxxx/users (1349ms)

11-04 01:02:53.295 19015-19371/com.xx D/OkHttp: **{"message":"Validation Failed","errors":[{"field":"password","code":"TooShort","message":"Le mot de passe doit contenir au moins 6 caract\u00e8res"}]}**
11-04 01:02:53.299 19015-19371/com.xx D/OkHttp: <-- END HTTP (150-byte body)

这是我的回调：

@Override
public void onResponse(Call<T>call, Response<T> response) {
    if (response.isSuccessful()) {
        onSuccessful(response.code(), response.body());

    } else {
        /// READ THE ERROR MESSAGE
        response.errorBody().string() > returns nothing!
    }
}

Answer 1

您可以按照以下方式查看状态代码和消息

Log.d("stattus_code",""+response.raw().code())
Log.d("stattus_code",""+response.raw().message())

所以它会是这样的

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

    Log.d("stattus_code",""+response.raw().code())
    Log.d("stattus_code",""+response.raw().message())
    if (response.isSuccessful()) {
        onSuccessful(response.code(), response.body());

    } else {
        /// READ THE ERROR MESSAGE
        response.errorBody().string() > returns nothing!
    }
}

使用此功能可以获取错误正文

  if (response != null && response.errorBody() != null) {
    JSONObject jsonObject = new JSONObject(response.errorBody().string());
    String message = jsonObject.getString("message");
    String errors =  jsonObject.getString("errors");
  }
