## Instance Method Summary (collapse)

- - (void) authenticate(authInfo = nil) { ... }
  Authenticate a user.

## Instance Method Details

### - (`void`) authenticate(authInfo = nil) { ... }

This method returns an undefined value.

Authenticate a user.

The first argument is a JSON object containing information for authenticating the user. What this actually contains depends on the specific implementation. In the case of a simple username/password based authentication it is likely to contain a JSON object with the following structure:

       {
         "username": "tim",
         "password": "mypassword"
       }

For other types of authentication it contain different information - for example a JWT token or OAuth bearer token.

If the user is successfully authenticated a User object is passed to the handler in an AsyncResult. The user object can then be used for authorisation.

Parameters:

- authInfo (`Hash{String => Object}`) (defaults to: `nil`) —
  The auth information

Yields:

- The result handler

Raises:

- (`ArgumentError`)
