These methods are available on HTTPPasswordMgr and
HTTPPasswordMgrWithDefaultRealm objects.
add_password(
realm, uri, user, passwd)
uri can be either a single URI, or a sequence of URIs. realm,
user and passwd must be strings. This causes
(user, passwd) to be used as authentication tokens
when authentication for realm and a super-URI of any of the
given URIs is given.
find_user_password(
realm, authuri)
Get user/password for given realm and URI, if any. This method will
return (None, None) if there is no matching user/password.
For HTTPPasswordMgrWithDefaultRealm objects, the realm
None will be searched if the given realm has no matching
user/password.
