Configuration

Guards

Reauth package provides new form of Guard. Guard has two attributes - 'driver' and 'pipelines'.

'Driver' attribute assigns token source per each http requests. 'Bearer' driver requires that each http request has a bearer token carried by "Authorization" header. it means that each request should contain header like this:

'Json' driver requires that json request body contains specified attribute, such as "custom_id" in the example above.

Pipelines

Guard has one or more pipelines to pass the result of authentication from token to trailing processes such as Controller. Each pipeline is processed in order, finishes when authenticated user picked up (and later ones are abandoned).

Resolver

Resolver has role for decoding of raw token string (or pass through if it is "opaque" token) and arrange it into "credentials" for UserProvider::retrieveByCredentials() usage.

There are two ways to configure resolver how it works. The first one is to use class instance that implements TokenResolverInterface, like this.

This class OpaqueAccessTokenResolver fulfills TokenResolverInterface i.e. credentialsFromToken method.

The other one is anonymous function like this:

The signature of this anonymous function is similar with TokenResolverInterface::credentialsFromToken().

[!WARNING] If you don't care decoded token in trailing process (ex. Controller) you can omit and ignore the second parameter like this,

although it is NOT recommended.

Resolver works for these processes:

• if the input token has certain encoding, encrypting, format and so on, resolver can decompose raw token string into appropriate structure.
• (if necessary) check the token if it is available or not - expiration limit, ownership of token, source address, etc.
• arrange the information of token into "credentials" - for UserProvider use.

Users (= UserProvider)

Users(UserProvider) has role for User search that matches with credentials derived from previous processes. UserProvider is similar with ordinary ones defined in Laravel Auth. "Reauth" package provides additional functionality using User-related model classes.

• AccessTokenUserProvider
• AttributionalUserProvider
