How to fix httplib.BadStatusLine exception?


URL = "MY HTTP REQUEST URL"
XML = "<port>0</port>"

parameter = urllib.urlencode({'XML': XML})
response = urllib.urlopen(URL, parameter)
print response.read()


IOError: ('http protocol error', 0, 'got a bad status line', None)

I am trying to send XML to a server and get back XML. Is there any way to fix / ignore this exception?

I know that the status line is empty which is raising this error.


Solution

  • Try to have a look what your server actually returns! It probably isn't a valid HTTP response. You could use something like this to send a raw http request to the server:

    from socket import socket
    
    host = 'localhost'
    port = 80
    path = "/your/url"
    xmlmessage = "<port>0</port>"
    
    s = socket()
    s.connect((host, port))
    s.send("POST %s HTTP/1.1\r\n" % path)
    s.send("Host: %s\r\n" % host)
    s.send("Content-Type: text/xml\r\n")
    s.send("Content-Length: %d\r\n\r\n" % len(xmlmessage))
    s.send(xmlmessage)
    for line in s.makefile():
        print line,
    s.close()
    

    The response should look something like:

    HTTP/1.1 200 OK
    <response headers>
    
    <response body>
