CredentialStore

class pyvo.auth.CredentialStore

Bases: object

The credential store takes user credentials, and uses them to create appropriate requests sessions for dispatching requests using those credentials.

Different types of credentials can be passed in, such as cookies, a jar of cookies, certificates, and basic auth.

A session can also be associated with a security method URI by calling the set function.

Before a request is to be dispatched, the AuthSession calls the get method to retrieve the appropriate requests.Session for making that HTTP request.

Methods Summary

get(method_uri)	Retrieve the requests.Session like object associated with a security method URI.
negotiate_method(allowed_methods)	Compare the credentials provided by the user against the security methods passed in, and determine which method is to be used for making this request.
set(method_uri, session)	Associate a security method URI with a requests.Session like object.
set_client_certificate(certificate_path)	Add a client certificate to use for authentication.
set_cookie(cookie_name, cookie_value[, ...])	Add a cookie to use as authentication.
set_cookie_jar(cookie_jar)	Set the cookie jar to use for authentication.
set_password(username, password)	Add a username / password for basic authentication.
