I have been trying for many days now, so here I am finally asking, may be dumb question for most of the experts.
I am using PyUnit for API testing of my application. The application (to be tested) is deployed on one of the local servers over here. The application prevents hackers from doing malicious activities. So I am accessing any website (protected by this application) through this application. e.g. http://my-security-app/stackoverflow/login , http://my-security-app/website-to-be-protected etc.

Almost the whole framework is running around Urllib and Urllib2.

Scenario:- I need to send a request without 'Host' header or a request with 'Host123' as a header name instead of original, using python.

I have been trying below mentioned code. But its not working for me.

"Test failed because of an exception: [Errno 9] Bad file descriptor"

    host = "12.1.3.16"
    with closing(socket.create_connection((host, 80))) as s:
     # send request without Host header
        s.sendall(b"GET /mywebsite/administrator/ HTTP/1.1\r\n" +
        #"Host12:{}\r\n".format(host).encode('ascii', 'strict') +
        b"Connection: close\r\n\r\n")

Any help would be deeply appreciated.

Thanks in advance!

  • By definition response is sent by the server. If it is sent to the server then it is a request. If a server sends requests then it plays a role of a client for the exchange. Anyway, you could define a mock server for testing that sends preconfigured responses that contain whatever you like. Commented Mar 13, 2014 at 10:42
  • Thanks Sebastian for a quick response. Even I was confused with the term "response" because as per my understanding, we can't manipulate the response coming from the server, using python. Now coming to our problem. Suppose I want to check if I can send duplicate headers in a request to the server. Could you provide any help regarding that? Commented Mar 13, 2014 at 10:59
  • you need to be more specific aka provide a minimal code example that sends a header and show your attempt to duplicate the header. Commented Mar 14, 2014 at 9:21
  • I got it Sebastian, I sent out some data (request) so that I can get some specific headers twice in response. Thanks btw for your co-operation. I have one more challenge now. In the same scenario I need to replace 'Host' in the request with 'Host123' before sending out the request. Any clues? Commented Mar 15, 2014 at 16:00
  • you could use socket directly to send invalid http request. Here's code example Commented Mar 15, 2014 at 16:47

Use httpbin test server for this. It is written in Python, btw.

Description:

Testing an HTTP Library can become difficult sometimes. PostBin.org is fantastic for testing POST requests, but not much else. This exists to cover all kinds of HTTP scenarios. Additional endpoints are being considered (e.g. /deflate).

All endpoint responses are JSON-encoded.

Author provides even public service based on this server at http://httpbin.org
