Token Manager

Token Manager classes.

There should be a 1-to-1 mapping betwen an instance of a subclass of BaseTokenManager and a Reddit instance.

A few trivial token manager classes are provided here, but it is expected that PRAW users will create their own token manager classes suitable for their needs.

See ref:using_refresh_tokens for examples on how to leverage these classes.

class praw.util.token_manager.BaseTokenManager

An abstract class for all token managers.

__init__()

Prepare attributes needed by all token manager classes.

post_refresh_callback(authorizer)

This function will be called after refreshing the access and refresh tokens. This callback can be used for saving the updated refresh_token.

pre_refresh_callback(authorizer)

Handle callback that is invoked before refreshing PRAW’s authorization.

Parameters

authorizer – The prawcore.Authorizer instance used containing access_token and refresh_token attributes.

This callback can be used to inspect and modify the attributes of the prawcore.Authorizer instance, such as setting the refresh_token.

property reddit

Return the Reddit instance bound to the token manager.

class praw.util.token_manager.FileTokenManager(filename)
