我需要创建一个比原始信息更少的 JSON 对象:
从 api 服务获取原始 JSON 对象后，它看起来像这样:
{
"queryResponse": {
"@type": "AccessPointDetails",
"@rootUrl": "https://xxx/webacs/api/v1/data",

}

}
}
我需要创建一个新的 JSON 对象，其中仅包含上面的一些信息，如下所示:
"entity": [
{
"@id": 12345,
"name": asdf,
"clienCount": 5,
"clientCount_2_4GHz": 3,
"clientCount_5GHz": 2
},
{
"@id": 12345,
"name": asdf,
"clienCount": 5,
"clientCount_2_4GHz": 3,
"clientCount_5GHz": 2
}
]
如果你看一下，实体列表位于原始数据的字典内。
我尝试查找相关信息，但只找到了如何删除或如何每次提取 1 条数据的信息。
如何在 Python 中执行此操作？
问候。

最佳答案
您的问题只是 python getting a list of value from list of dict 的组合和 Filter dict to contain only certain keys?
通过使用这两个问题的解决方案，您可以实现它:
假设 s 是从 json 数据转换而来的 dict。
keys = ['@id', 'name', 'clientCount', 'clientCount_2_4GHz', 'clientCount_5GHz']
new_dict = {'entity': [{key: d['accessPointDetailsDTO'][key] for key in keys} for d in s['queryResponse']['entity']]}
然后使用 json.dumps 转换 new_dict :
your_json_object = json.dumps(new_dict)
