如果找不到路由，如何处理404作为json响应？

Question

Using Laravel 5.4, I would like to send the json response, while there is no route found in api.php, how can I archive with in api.php and without Controller and Model class.

short: How to handle when the route name is incorrect?

Tried with fallback :

Route::fallback(function(){
    return response()->json(['message' => 'Not Found!'], 404);
});

Error for above :

Attribute [fallback] does not exist.

Please help me, how to handle Route not found exception when incorrect route name request.

Answer 1

fallback available since version 5.6. try Route::any()

add at the end of your api.php (below all of the other routes) something like

Route::any('{path}', function() {
    return response()->json([
        'message' => 'Route not found'
    ], 404);
})->where('path', '.*');

how can I archive with in api.php and without Controller and Model class

In my opinion using of anonymous function as route handler it's not a best idea, because you can't cache your routes if you're using closures and it causes some overhead.
