[SOLVED] Python http.client getaddrinfo failed

Python http.client getaddrinfo failed

I am using http.client to try to read an xml file from a host. I would use urllib2, but I get a BadStatusLine because there is 3 spaces before the xml header(I can not change that). That is why I am trying this route.

I am stuck now and I keep getting an error (getaddrinfo failed).

Below is my code and below that is the traceback. Can someone advise what I am doing wrong?

FYI the address that works on the browser is http://machineIP:81/command=AB&time=2013-06-02

I have no problem accessing the xml that way.

Thanks for any help in advance!

Code:

import http.client
import datetime

IP = input("Enter the IP: ")
PT = str(81)
F1 = datetime.date.today() - datetime.timedelta(days=2)

print("Reading File...")
html = http.client.HTTPConnection('http://' + IP  , port= PT)
html.request("GET", '/command=AB&time=' + str(F1))
r1 = html.getresponse()

print("Writing to file...")
out = r1.read()
f = open('Files/' + IP + '-' + str(F1) + '.xml', 'wb')
print("Writing to file...")
f.write(out)
f.close()
print("Done.")

Traceback:

Solution

So I figured it out. To avoid badStatusLines and other similar errors I used sockets/urllib2. That way you can get the raw info from the webpage and not have to worry about any issues you can not control.

here is the snippet of code with sockets added.

socket.setdefaulttimeout(timeout)
req = urllib2.Request(host)
response = urllib2.urlopen(req)

This was the only success I found so far. Thanks to ejno for getting me on the right track.
