Sending a HTTP request using python

I have intercepted an HTTP request using FIDDLER.

I would like to send the same request, just this time using python and not my browser.

I did some research and found that httplib is the way to go, but for some reason my code does not work.

No request is sent from my computer (I can verify this by using FIDDLER).

Any ideas whats wrong ?

import httplib

headers = {
"Host":" unive.edu",
"Connection":" keep-alive",
"Content-Length":" 5142",
"Cache-Control":" max-age=0",
"Accept":" text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",

}

body = ""

conn = httplib.HTTPConnection("unive.edu")
conn.request("POST", "/web/SelectCoursePage2.aspx?dtticks=635358682524828750&hideBackButton=1", None, headers)
res = conn.getresponse()

Thanks, Michael.

Solution

The problem is that you've got a Content-Length header claiming that you're going to send the server 5142 bytes in the POST body but you're not sending any body content at all. As a consequence, the server hangs waiting for the body; it will probably fail with a time out in a few minutes.

To fix this, ensure that the Content-Length header matches the length of the body in bytes.
