類型為'_NestedList'的python＆livejson對象不是JSON可序列化的

Question

好的，所以我試圖做一個字典重命名函數，但是我一直收到錯誤消息Object of type '_NestedList' is not JSON serializable無論我做什么， Object of type '_NestedList' is not JSON serializable ，我已經嘗試了一些方法，當我嘗試將它們替換時，它們可以工作沒問題...除非我要嘗試一下。

它的json看起來像custom["commands"]["command"]["beep"]
所以我想做的就是將其更改為custom["commands"]["command"]["boom"]

{
    "command": {},
    "commands": {
        "command": {
            "beep": {
                "created": "2018-11-04 16:32:50.013260",
                "created2": 1541349170.0132835,
                "createdby": "me",
                "disablefor": [],
                "enabledfor": [],
                "message": "asd",
                "public": "self",
                "type": "text",
                "unsendtimer": 0,
                "unsendtrigger": false
            },
            "bep": {
                "created": "2018-11-04 16:34:38.723840",
                "created2": 1541349278.7238638,
                "createdby": "me",
                "disablefor": [],

                "message": "asd",
                "public": "self",
                "type": "text",
                "unsendtimer": 0,
                "unsendtrigger": false
            },
            "boop": {
                "STKID": "423",
                "STKPKGID": "1",
                "STKVER": "100",
                "created": "2018-10-27 00:53:38.067740",
                "created2": 1540601618.0677645,
                "createdby": "me",
                "disablefor": [
                    "u69a0086845f2d38c5ecfd91a7601f3c1",
                    "ua2ed27b7932f647b492daa68ef33c0cc"
                ],
                "enabledfor": [],
                "message": "8775249726676",
                "public": "on",
                "type": "sticker",
                "unsendtimer": 0,
                "unsendtrigger": true
            }
        },
        "commandgrab": false,
        "commandgroup": ""
    }
}

這就是json文件的樣子，任何人有任何建議，我都會愛上他們，謝謝

您正在使用livejson包，而不是python的內置json包。

livejson json結構是livejson對象的樹； 顯然livejson不直接支持在鍵之間移動這些對象：

>>> import livejson
>>> test['foo'] = {'bar': {'baz': [1, 2, 3]}
>>> test
{'foo': {'bar': {'baz': [1, 2, 3]}}}

>>> type(test['foo']['bar']['baz'])
<class 'livejson._NestedList'>


>>> test['foo']['bar']['quux'] = test['foo']['bar']['baz']
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  ...
TypeError: Object of type _NestedList is not JSON serializable

livejson對象具有data屬性，該屬性返回標准python列表和livejson包裝的字典，因此您需要使用此屬性來重新分配鍵的值：

>>> test['foo']['bar']['quux'] = test['foo']['bar']['baz'].data

# Now remove the old value
>>> del test['foo']['bar']['baz']
>>> test

{'foo': {'bar': {'quux': [1, 2, 3]}}}
