使用Python解析JSON以获取特定值

Question

I am trying to parse JSON with Python. I am trying to get the value of "login" which is michael for "type" which is "CreateEvent".

Here's my JSON:

[

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

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

Here's my code:

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

When I run the above code, I get a type error.

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

What am I doing wrong? I am using Python3 for my code.

Answer 1

Try

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

The name Michael you are trying to get, is inside the dictionary named author, which is inside a single item list, which is inside the commits dictionary, which is inside the payload dictionary, which is inside a single item list.
