Question

我正在开发适用于Android的应用，当我提交GET时，REST Server返回以下JSON答案：

{
    "result": "ok",
    "code": 1000,
    "code_desc": "Command Done Successfully",
    "method": "get",
    "call_id": null,
    "timestamp": 1539100644,
    "weight": {
        "1": {
            "id": 1,
            "customer_id": 1,
            "date": "2018-10-04 12:02:00",
            "value": 100,
            "observations": ""
        },
        "2": {
            "id": 2,
            "customer_id": 1,
            "date": "2018-10-04 12:02:00",
            "value": 100,
            "observations": ""
        }
    },
    "order": "date",
    "sorder": "ASC",
    "total": 2
}

JSON是有效的，但是当我尝试读取内容时，它返回null。我认为这是因为对象“权重”的形成不良。

是否应更改服务器中的JSON？像这样：

{
                "result": "ok",
                "code": 1000,
                "code_desc": "Command Done Successfully",
                "method": "get",
                "call_id": null,
                "timestamp": 1539100644,
                "weight": [{
                                               "id": 1,
                                               "customer_id": 1,
                                               "date": "2018-10-04 12:02:00",
                                               "value": 100,
                                               "observations": ""
                               },
                               {
                                               "id": 2,
                                               "customer_id": 1,
                                               "date": "2018-10-04 12:02:00",
                                               "value": 100,
                                               "observations": ""
                               }
                ],
                "order": "date",
                "sorder": "ASC",
                "total": 2
}

您很有可能尝试将响应读入某些List<Object>，而服务器响应看起来像是Map<String, Object>。考虑到它，尝试更改您的代码

改造响应Json
