How to get all the content of a page?

Python 3: Can I get a webpage header information without get page content?

• I know that if I send a http request to some website, I will got http header information back and http content,  and I wonder if I can only get the header information without get content for  a low network speed. (using python3 language is  appreciate, If some python3 package can do that , tell me the module name is OK)

• Answer:

  Yes, this is the http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.4 HTTP verb. In Python 3, you can do a HEAD request using the http.client module (note: in Python 2, it’s called httplib): >>> from http import client >>> conn = client.HTTPConnection( "www.quora.com" ) >>> conn.request( "HEAD", "/Zhang-Peipei" ) >>> res = conn.getresponse() >>> print( res.status, res.reason ) 403 Forbidden >>> print( res.getheaders() ) [('Cache-Control', 'no-cache'), ('Content-Type', 'text/html'), ('Connection', 'keep-alive')] >>> res.read() b'' # there is no body, only headers Documentation: http://docs.python.org/3.0/library/http.client.html
