Slim 3 - Fatal error: Cannot use object of type Slim\Http\Request as array about slim-jwt-auth HOT 3 CLOSED

Use examples from Slim 3 branch README instead. Master is currently for Slim 2.

$app->add(new \Slim\Middleware\JwtAuthentication([
    "secret" => "supersecretkeyyoushouldnotcommittogithub",
    "callback" => function ($request, $response, $arguments) use ($app) {
        $app->jwt = $arguments["decoded"];
    }
]));

Since we can't get $app instance inside a route callable class, what's the purpose of set $app->jwt? Sounds wrong, it's only work inside a route function() definition.

Callback is just an example and that is how I happen to use it. You can of course store the the decoded value somewhere else. Or you can decide not to store it anywhere at all.

As the readme says it is up to you to implement how the token data is stored or possible authorization implemented. Middleware itself does only authentication, ie makes sure the passed token is valid. Using callback is optional. It is provided that you can do something with the decoded token when needed.
