Python Urllib2, Basic Http Authentication, and Tr.Im

Python urllib2, basic HTTP authentication, and tr.im

This seems to work really well (taken from another thread)

import urllib2, base64

request = urllib2.Request("http://api.foursquare.com/v1/user")
base64string = base64.encodestring('%s:%s' % (username, password)).replace('\n', '')
request.add_header("Authorization", "Basic %s" % base64string)   
result = urllib2.urlopen(request)

Python urllib2 Basic Auth Problem

The problem could be that the Python libraries, per HTTP-Standard, first send an unauthenticated request, and then only if it's answered with a 401 retry, are the correct credentials sent. If the Foursquare servers don't do "totally standard authentication" then the libraries won't work.

Try using headers to do authentication:

import urllib2, base64

request = urllib2.Request("http://api.foursquare.com/v1/user")
base64string = base64.b64encode('%s:%s' % (username, password))
request.add_header("Authorization", "Basic %s" % base64string)   
result = urllib2.urlopen(request)

Had the same problem as you and found the solution from this thread: http://forums.shopify.com/categories/9/posts/27662

urllib2 basic authentication oddites

About an year ago, I went thro' the same process and documented how I solved the problem - The direct and simple way to authentication and the standard one. Choose what you deem fit.

HTTP Authentication in Python

There is an explained description, in the missing urllib2 document.

How to use urllib with username/password authentication in python 3?

Thankfully to you guys I finally figured out the way it works.
Here is my code:

request = urllib.request.Request('http://mysite/admin/index.cgi?index=127')
base64string = base64.b64encode(bytes('%s:%s' % ('login', 'password'),'ascii'))
request.add_header("Authorization", "Basic %s" % base64string.decode('utf-8'))
result = urllib.request.urlopen(request)
resulttext = result.read()

After all, there is one more difference with urllib: the resulttext variable in my case had the type of <bytes> instead of <str>, so to do something with text inside it I had to decode it:

text = resulttext.decode(encoding='utf-8',errors='ignore')

urllib2 + Basic authentication + CookieJar

or a different library i can use
