android - 如何处理改造中的两种不同响应

Question

我关注了this使用 Retrofit2 POST 数据

我用过JSON POJO解析我的 POST 和 GET 文件

所以如果记录中的数据存在，我会得到这种响应

{
"status": "200",
"response": [{
        "cnt_id": "201",
        "phn_no": "3251151515",
        "dat_cnt": "Reset Password request Said to Mail"
    },
    {
        "cnt_id": "209",
        "phn_no": "555465484684",
        "dat_cnt": "Hi DEMO User , Congratulations! Your account has been created successfully."
    },
    {
        "cnt_id": "210",
        "phn_no": "4774748",
        "dat_cnt": "Hi XYZ , Congratulations! Your account has been created successfully."
    }
]
}

如果没有数据我会得到

{"status":"204","re​​sponse":{"msg":"无内容"}} 或
{"status":"400","re​​sponse":{"msg":"BadRequest"}} 或
{"status":"401","re​​sponse":{"msg":"未经授权的用户"}}

所以在这里我可以解析状态 200 中的数据，但是当状态不等于 200 时我想处理它们

我尝试过

   status = response.body().getStatus();
   if(status.equals("200")) {
      List<Response> resList =  response.body(). getResponse();

            for(int i = 0; i<resList.size(); i++)
            {.
             .
              ..
             .
            }
        }

        else {
             //not Implemented
             }

现在我应该写什么，否则我在 POJO 中使用了响应数据，它不等于 200，但我要求列表

更新

com.example.Example.java

public class Example {
    @SerializedName("status") @Expose private String status;
    @SerializedName("response") @Expose private List<Response> response = null;
}        

com.example.Response.java

public class Response {
    @SerializedName("cnt_id") @Expose private String cntId;
    @SerializedName("phn_no") @Expose private String phnNo;
    @SerializedName("dat_cnt") @Expose private String datCnt;
}

Answer 1

public class Example {
    @SerializedName("status") @Expose private String status;
    @SerializedName("response") @Expose private Object response = null;
}

public class Response {
    @SerializedName("cnt_id") @Expose private String cntId;
    @SerializedName("phn_no") @Expose private String phnNo;
    @SerializedName("dat_cnt") @Expose private String datCnt;
}

public class ResponseError{
    @SerializedName("msg") @Expose private String msg;
}

你的回调方法应该是这样的

new Callback<Example>() {
    @Override
    public void onResponse(Call<Example> call, Response<Example> response) {
       if (response.isSuccessful()){
          Example example = response.body();
          Gson gson = new GsonBuilder().create();

          if (example.status.equals("200")) {
              TypeToken<List<Response>> responseTypeToken = new TypeToken<List<Response>>() {};
              List<Response> responseList = gson.fromJson(gson.toJson(example.getResponse()), responseTypeToken.getType());
          } else {
              //If for everyOther Status the response is Object of ResponseError which contains msg.
              ResponseError responseError = gson.fromJson(gson.toJson(example.getResponse()), ResponseError.class);
          }
       }
    }
    
    @Override
    public void onFailure(Call<Example> call, Throwable t) {
        //Failure message
    }
}
