couchDB , python and authentication

Question

I have installed couchDB v 0.10.0, and am attempting to talk to it via python from Couch class downloaded from couchDB wiki. Problem is:

Create database \'mydb\'         


        

Answer 1

There are several patches for python-couchdb that enable authentication. The code probably will be included in Version 0.7 but until then you can usr teh fork at http://github.com/mdornseif/couchdb-python - it allows you to use http://user:pass@127.0.0.1:5984/ type URLs.

http://blogs.23.nu/c0re/2009/12/running-a-couchdb-cluster-on-amazon-ec2/ (at the bottom) shows how to use CouchDB passwords.

Answer 2

Just pass it as part of the URI...python-couchdb will parse the user/pass out and use them:

http://user:pass@localhost:5984

Answer 3

The Couch class in the example does not pass any authentication information to the database, so it is not a miracle that it does not allow privileged operations. So your only options are:

• disable authentication completely (as you mentioned)
• pass the user name and password as part of the URI
• pass the user name and password as an Authorization HTTP request header

If you want to pass a user name and a password, then you will need to change the Couch class. Sending an Authorization HTTP request header is easier, since the Couch class uses the httplib.HTTPConnection class. You can add such a header next to the Accept one this way:

headers = {
    "Accept": "application/json",
    "Authorization": "Basic " + 'username:password'.encode('base64')[:-1]}

Same for the other HTTP request methods.

The documentation on the basic authentication is here:

Answer 4

You can also do:

db = couchdb.Database("http://your.url/yourdb")
db.resource.http.add_credentials(username, password)

after which all your requests should work.

Answer 5

Above are all nice; but I've found that for oauth validation methods versus basic auth, this works really well:

from couchdb import Server, Session
auth = Session()
auth.name = USERNAME
auth.password = PASSWORD
s = Server('http://localhost:5984/', session=auth)
db = s['dbname']

Note: This will not work with basic authentication; in such a case, fviktor has what I consider to be the best answer. You might also look into the security reference material he linked to if you're interested in persistent auth sessions.

Answer 6

To concour David's reply, (i.e. "This is how I do it using module CouchDB 0.8 in python 2.6 with couchdb 1.0.2")

couch = couchdb.Server(couch_server)

couch.resource.credentials = (USERNAME, PASSWORD)
