昨天，我们更多的讨论了request的基础API，让我们对它有了基础的认知。学会上一课程，我们已经能写点基本的爬虫了。但是还不够，因为，很多站点是需要登录的，在站点的各个请求之间，是需要保持回话状态的，有的站点还需要证书验证，等等这一系列的问题，我们将在今天这一环节，加以讨论。 1.会话对象会话：session，就是你点进这个站点后，由浏览器与服务器之间保持的一次连接。这次连接里面，你跳转页面，或发起其他请求，服务器要求某些数据验证。服务器不会叫你在每次跳转时候进行验证，而是用已验证的结果进行跳转。这样就节省服务器资源，底层的TCP连接也会被重用。跨请求保持数据（客户端存数据）： s = requests.Session() s.get(' http:// httpbin.org/cookies/set /sessioncookie/123456789 ') r = s.get(" http:// httpbin.org/cookies ") print(r.text) 回话提供请求默认数据（数据会被存到服务端）： s = requests.Session() s.auth = ('user', 'pass') s.headers.update({'x-test': 'true'}) # 'x-test' 和 'x-test2' 一起发送给url s.get(' http://
