This allows users of the library to easily render VerUrl to use in
verification emails to new users, if the user was created outside
of the regular register functionality.
- getAuthId returns Maybe AuthId with no useful information in the
Nothing case.
- AuthenticationResult includes whether it was a User or Server error
(with an accompanying message) in the failure case.
- User errors are displayed back to the user and have a 401 status in
JSON responses. Server errors are logged and a generic error message
is presented to the user, with a 500 status in JSON responses.
Resolves#956
The existing GoogleEmail2 auth did that:
- Acquire user access token with offline access
- Use token to acquire user's profile
- Build `Creds` with user's email as `ident` and the other profile
details as stringy key-value pairs in `credsExtra`
This wasn't enough for me, for several reasons:
- Access token was not saved after authentication. If we request 'offline'
token why not to have a way of using it later.
- Stringy key-value profile is not nice and `credsExtra` can be accessed
only from `getAuthId`
- I might want to request the profile after authentication process
So I've added the needed features.
- The access token is saved in a session
- There is a `Person` type with `FromJSON` instance and `getPerson`
can be used to acquire it from `HandlerT`
Added support for `Logout` message, all translations made with Google
Translate, except: Russian translation (by hand) and Dutch translation
