import requestsreq = requests.get(url)

一般用上述寫法，訪問網頁久了會變卡，那么可以用下面方法替代

session = requests.Session() req = session.get(url)

也就是說，requests 讓 Session對象能夠保持連接：

The Session object allows you to persist certain parameters across requests. It also persists cookies across all requests made from the Session instance, and will use urllib3’s connection pooling. So if you’re making several requests to the same host, the underlying TCP connection will be reused, which can result in a significant performance increase (see HTTP persistent connection).
