用Python解析JSON以获得特定的值

Question

我正在尝试用Python解析JSON。我试图得到“login”的值，它是michael的值，而“type”是CreateEvent的值。你知道吗

这是我的JSON：

[

    "id": "7",
    "type": "PushEvent",
    "actor": {

        "gravatar_id": "",
        "url": "https://ec2",
        "avatar_url": "https://ec2"
      }
        }
      ]

这是我的密码：

response = requests.get(url, headers=headers, verify=False)
name = response.json()
fname = (name['type']['actor']['login'])
print(fname)

当我运行上面的代码时，我得到一个类型错误。你知道吗

TypeError: list indices must be integers or slices, not str.

我做错什么了？我正在使用Python3作为我的代码。你知道吗

Answer 1

试试看

fname = name[0]['payload']['commits'][0]['author']['name']

您试图获取的名称Michael位于名为author的字典中，该字典位于单个项列表中，该字典位于提交字典中，该字典位于有效负载字典中，该字典位于单个项列表中。你知道吗
