【问题描述】：

我正在尝试打印 API 请求中的值。返回的 JSON 文件很大（4,000 行），所以我只是想从键值对中获取特定值并自动发送消息。

这是我目前所拥有的：

import requests
import json
import urllib


url = "https://api.github.com/repos/<companyName>/<repoName>/issues" #url 

payload = {}
headers = {
  'Authorization': 'Bearer <masterToken>' #authorization works fine 
}
name = (user.login) #pretty sure nothing is being looked out
url = (url)

print(hello %name, you have a pull request to view. See here %url for more information) # i want to print those keys here

JSON文件（从API获取请求导出如下：

[
    {
        **"url": "https://github.com/<ompanyName>/<repo>/issues/1000",**
        "repository_url": "https://github.com/<ompanyName>/<repo>",
        "labels_url": "https://github.com/<ompanyName>/<repo>/issues/1000labels{/name}",
        "comments_url": "https://github.com/<ompanyName>/<repo>/issues/1000",
        "events_url": "https://github.com/<ompanyName>/<repo>/issues/1000",
        "html_url": "https://github.com/<ompanyName>/<repo>/issues/1000",
        "id": <id>,
        "node_id": "<nodeID>",
        "number": 702,
        "title": "<titleName>",
        "user": {
            **"login": "<userName>",**
            "id": <idNumber>,
            "node_id": "nodeID",
            "avatar_url": "https://avatars3.githubusercontent.com/u/urlName?v=4",
            "gravatar_id": "",
            "url": "https://api.github.com/users/<userName>",
            "html_url": "https://github.com/<userName>",
            "followers_url": "https://api.github.com/users/<userName>/followers",
            "following_url": "https://api.github.com/users/<userName>/following{/other_user}",
            "gists_url": "https://api.github.com/users/<userName>/gists{/gist_id}",
            "starred_url": "https://api.github.com/users/<userName>/starred{/owner}{/repo}",
            "subscriptions_url": "https://api.github.com/users/<userName>/subscriptions",
            "organizations_url": "https://api.github.com/users/<userName>/orgs",
            "repos_url": "https://api.github.com/users/<userName>/repos",
            "events_url": "https://api.github.com/users/<userName>/events{/privacy}",
            "received_events_url": "https://api.github.com/users/<userName>/received_events",
            "type": "User",
            "site_admin": false
        },
]

（注意这个 JSON 文件重复了几百次）从 API 请求中，我试图获取嵌套的“登录”和 url。我错过了什么？谢谢

编辑：

已解决：

import requests
import json
import urllib


url = "https://api.github.com/repos/<companyName>/<repoName>/issues"

payload = {}
headers = {
  'Authorization': 'Bearer <masterToken>'
}

response = requests.get(url).json()
for obj in response:
    name = obj['user']['login']
    url = obj['url']
    print('Hello {0}, you have an outstanding ticket to review. For more information see here:{1}.'.format(name,url))

【解决方案1】：

由于它是一个 JSON 数组，因此您必须对其进行循环。并且 JSON 对象被转换为字典，因此您可以使用 ['key'] 来访问元素。

for obj in response:
    name = obj['user']['login']
    url = obj['url']
    print(f'hello {name}, you have a pull request to view. See here {url} for more information')

谢谢。我稍微修改了一下，但它完全有效。

【解决方案2】：

您可以将其解析为 python 列表/字典，然后像访问任何其他 python 对象一样访问它。


response = requests.get(...).json()

login = response[0]['user']

【解决方案3】：

您可以将 JSON 格式的数据转换为 Python 字典，如下所示： https://www.w3schools.com/python/python_json.asp

json_data = ... # response from API
dict_data = json.loads(json_data)

login = response[0]['user']['login']
url = response[0]['url']
