Python标准库中提供了：urllib、urllib2、httplib等模块以供Http请求，但是，它的 API 太渣了。
它是为另一个时代、另一个互联网所创建的。它需要巨量的工作，甚至包括各种方法覆盖，来完成最简单的任务。
Requests 是使用 Apache2 Licensed 许可证的 基于Python开发的HTTP 库，其在Python内置模块的基础上进行了高度的封装;
从而使得Pythoner进行网络请求时，变得方便了许多，使用Requests可以轻而易举的完成浏览器可有的任何操作。
# 1、无参数实例 import requests ret = requests.get(‘https://github.com/timeline.json‘) print(ret.url)
