How to send HTTP/1.0 request via urllib2?

Question

Seems that urllib2 sends HTTP/1.1 request by default?

Answer 1

To avoid monkey-patching httplib (global change), you could subclass HTTPConnection and define your own http handler:

#!/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])
