使用 Python 遍历 JSON 对象

Question

我有一个 JSON 对象，想知道如何遍历该对象以提取“id”的值。{"totalSize": 5,"done": true,"records": [    {        "attributes": {            "type": "EventLogFile",            "url": "/services/data/v38.0/sobjects/EventLogFile/0AT1U000003kk7dWAA"        },        "Id": "0AT1U000003kk7dWAA"    },    {        "attributes": {            "type": "EventLogFile",            "url": "/services/data/v38.0/sobjects/EventLogFile/0AT1U000003kk7eWAA"        },        "Id": "0AT1U000003kk7eWAA" 我在下面尝试一些东西。sub_data = s["records"]["id"]for i in sub_data:        print(sub_data['id'])

Answer 1

您可以将records键作为列表进行迭代，然后访问Id每个子字典的键：

for i in s["records"]:

    print(i['Id'])

Answer 2

s = """{ "totalSize": 5, 

        "done": true, "records": [ 

            { "attributes": { 

                "type": "EventLogFile", 

                "url": "/services/data/v38.0/sobjects/EventLogFile/0AT1U000003kk7dWAA" }, 

                "Id": "0AT1U000003kk7dWAA" } 

        ] 

    }"""

s = json.loads(s)

[r['Id'] for r in s['records']]

['0AT1U000003kk7dWAA']
