Error using httplib documentation example code

Fri Oct 8 19:56:19 EDT 2004

Hi.

I'm having some problems with code based directly on the following 
httplib documentation code:
   http://www.zvon.org/other/python/doc21/lib/httplib-examples.html

I've included the code[1] and traceback[2] at the end of this post.

The odd thing is, using DEPRECATED FUNCTIONS to perform the same 
function works fine!

The working code is based on the Python 2.1.1 documentation example code 
here: http://www.zvon.org/other/python/doc21/lib/httplib-examples.html

The working code[3] and partial result[4] are at the end of this post.

What sems to be the problem is that the read() method is getting caught 
up on the MIME-version part of the response -- is it expecting to 
receive the HTTP response code here?

If I paste the current httplib documentation code word-for-word (using 
the example site) it works...

Thanks for any help in advance!

                                'search_method':'long'})

                "Accept": "text/plain",
                "Host": "cnswww.cns.cwru.edu"}

     h = httplib.HTTPConnection("cnswww.cns.cwru.edu")
     h.request("POST", "/phone/phonebook/local/whois.cgi", headers=headers)
     h.send(params)
     r = h.getresponse()
     print r.status, r.reason
     d = r.read()
     print d
     h.close()
