2 GET 请求

*注意：每一个小节分为两个部分内容。上面的内容为python的 requests 请求，下面的内容为 socket 抓包获取的原始 http请求报文。

• 网址

  requests.get(url = "http://127.0.0.1:6000/")
  

  GET / HTTP/1.1
  Host: 127.0.0.1:6000
  User-Agent: python-requests/2.27.1
  Accept-Encoding: gzip, deflate
  Accept: */*
  Connection: keep-alive
  

• 带参数

  requests.get(url = "http://127.0.0.1:6000/?name=smile")
  

  GET /?name=smile HTTP/1.1
