android - 应为 BEGIN_ARRAY 但在第 1 行第 96 列路径中为 BEGIN_OBJECT

Question

这是我的json

{
    "success": true,
    "error": null,
    "responseA": {
        "responseB": [{
                    "response": {...},
                    "request": "\/observations\/atlanta,ga"
                }, {
                    "response": [{...}],
                    "request": "\/forecasts\/atlanta,ga"
                },
                ...
            ]
    }
}

我从这里为 json 创建我的类: http://www.jsonschema2pojo.org/

我发现标题的错误来自数组和对象这两个“响应”。

正如我所说的通过 Retrofit 分析那个，我如何通过 Retrofit2.0 分析这样一个具有两种类型(数组和对象)的“repsonse”的 json？谢谢~*

Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .build();`

这是日志:

Answer 1

你的 json 有错误:

responseB 第一个对象有一个response 对象，第二个对象有response 数组。这是制造问题

{

"success":true,

"error":null,

"responseA":{

  "responseB":[  
     {  

        "response":{... ***// This is object***
              },
        "request":"\/observations\/atlanta,ga"
     },
     {  
        "response":[   ***// This is Array***
           { ...
              }
        ],
        "request":"\/forecasts\/atlanta,ga"
     },
... ]

} }

您已经为数组对象创建了相同的结构。 希望这有帮助。 谢谢
