Connecting to socket with authentication in python

Question

I'm trying to connect to a mongodb instance through a python socket. The url looks like this

how can I connect to this with a python socket?

The following code gives me this error: [Errno -5] No address associated with hostname

import socket
import tornado

full_url = '%s:%s@%s' % (username, password, host)
s = socket.socket()
s.connect((full_url, port))
stream = iostream.IOStream(s)

EDIT - the reason I ask is because asyncmongo doesn't support this type of url right now. I'm trying to see if I can write a patch. The asyncmongo library connects using a socket like the one in the code above.

You should use a driver to connect to mongodb. If you are using Tornado (it looks like you intend to do so), try asyncmongo; if you are using a threaded web server/application framework (Django, Pylons, etc) you can use PyMongo directly.

Edit: As for why this code doesn't work, the socket module doesn't accept URLs for connection, just hostname and port. It is a low-level library. To connect to (web) urls, consider using urllib2 or httplib.

Edit 2: Authentication in MongoDB is not handled at the transport level, it's handled at the application level. I suggest you first read Implementing Authentication in a Driver, and then take a look at how PyMongo implements authentication (in connection.py and database.py). You'll also need to port or reimplement the MongoDB connection URI parsing for asyncmongo, which is documented here.
