Lumen / Laravel-自定义身份验证中间件错误

Question

I've created authentication middleware for a lumen project. The authentication uses an external API, but unless I'm mistaken, that's not the issue here. The middleware correctly redirects me to the login page if I'm not authenticated, and correctly logs me in and saves it in the session when I put in good credentials. But it won't display the internal homepage as long as I'm using the middleware. The "handle" method in App\\Http\\Middleware\\Authenticate.php seems to have no Response in $next($request) to return and I'm not sure why.

If my UserProvider implementation or AuthController is needed, let me know.

Answer 1

Your syntax in the route.php file is wrong.

If you use a middleware in the route the function has to be in the array too:

$app->get('/', ['middleware' => 'bankerAuth', function () use ($app) {
    return 'Home page';
}]);

Answer 2

Tested and absolutely working. I added this in my dir/app/Http/routes.php file.

$app->get('/', function() use ($app) {
return $app->welcome(); });

$app->get('/home', function() use ($app) { return "Welcome to Homepage"; });
