17.1 使用Web API

        Web API作为网站的一部分，用于与使用具体URL请求特定信息的程序交互，这种请求称为API调用。

        17.1.1 Git 和 GitHub

                Git：分布式版本控制系统，帮助人们管理为项目所做的工作，避免一个人所做的影响其他人所做的修改（类似于共享文档）。在项目实现新功能时，Git跟踪你对每个文件所做的修改，确认代码可行后，提交上线项目新功能。如果犯错可撤回，可以返回之前任何可行状态。

                GitHub：让程序员可以协助开发项目的网站。

        17.1.2 使用API调用请求数据             

浏览器地址栏输入：https://api.github.com/search/repositories?q=language:python&sort=stars

                显示结果：

{"total_count": 14026425,"incomplete_results": true,"items": [{"id": 54346799,"node_id": "MDEwOlJlcG9zaXRvcnk1NDM0Njc5OQ==","name": "public-apis","full_name": "public-apis/public-apis","private": false,"owner": {"login": "public-apis","id": 51121562,"node_id": "MDEyOk9yZ2FuaXphdGlvbjUxMTIxNTYy","avatar_url": "https://avatars.githubusercontent.com/u/51121562?v=4","gravatar_id": "","url": "https://api.github.com/users/public-apis","html_url": "https://github.com/public-apis","followers_url": "https://api.github.com/users/public-apis/followers","following_url": "https://api.github.com/users/public-apis/following{/other_user}","gists_url": "https://api.github.com/users/public-apis/gists{/gist_id}","starred_url": "https://api.github.com/users/public-apis/starred{/owner}{/repo}","subscriptions_url": "https://api.github.com/users/public-apis/subscriptions","organizations_url": "https://api.github.com/users/public-apis/orgs","repos_url": "https://api.github.com/users/public-apis/repos","events_url": "https://api.github.com/users/public-apis/events{/privacy}","received_events_url": "https://api.github.com/users/public-apis/received_events","type": "Organization","site_admin": false},"html_url": "https://github.com/public-apis/public-apis","description": "A collective list of free APIs",

        17.1.3 安装Requests

        17.1.4 处理API响应

import requests# 执行API调用并存储响应
url = 'https://api.github.com/search/repositories?q=language:python&sort=stars'
# 指定headers显示地要求使用这个版本的API
headers = {'Accept': 'application/vnd.github.v3+json'}
# requests调用API
r = requests.get(url, headers=headers)
# 状态码200表示请求成功
print(f"Status code:{r.status_code}")
# 将API响应赋给一个变量
