改造響應 Json

Question

我正在為 Android 開發應用程序，當我提交GET時，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，但是當我嘗試讀取內容時，它返回null 。 我認為是因為物體重量的形成不好。

來自服務器的 JSON 是否應該更改？ 類似於：

{
                "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
}

很可能您正在嘗試將響應讀入某些List<Object>而服務器響應看起來像Map<String, Object> 。 考慮到它，嘗試更改您的代碼
