python - 如何通过 urllib2 发送 HTTP/1.0 请求？

Question

好像urllib2默认发送HTTP/1.1请求？

Answer 1

为避免猴子修补 httplib(全局更改)，您可以子类化 HTTPConnection 并定义您自己的 http 处理程序:

#!/usr/bin/env python
try:
    from httplib import HTTPConnection
    from urllib2 import HTTPHandler, build_opener
except ImportError: # Python 3
    from http.client import HTTPConnection
    from urllib.request import HTTPHandler, build_opener

class HTTP10Connection(HTTPConnection):
    _http_vsn = 10
    _http_vsn_str = "HTTP/1.0" 

class HTTP10Handler(HTTPHandler):
    def http_open(self, req):
        return self.do_open(HTTP10Connection, req)

opener = build_opener(HTTP10Handler)
print(opener.open('http://stackoverflow.com/q/13656757').read()[:100])
