API Resource Routes and Route Groups not working

[georgehanson]

• Laravel Version: 5.7.8
• PHP Version: 7.2.6
• Database Driver & Version: MariaDB 10.2

Description:

When making HTTP requests to routes within a route group, where an API Resource route group has been registered before, the routes do not match and a 404 response is returned.

Steps To Reproduce:

• Create a new Laravel project
• In your routes file, add the following routes:

$router->group(['prefix' => '/v1', 'middleware' => ['auth:api']], function ($router) {
    $router->apiResource('/contacts', 'ContactsController');

    $router->group(['prefix' => '/contacts'], function ($router) {
        $router->apiResource('/groups', 'Contacts\\GroupsController');
    });
});

GET requests to /api/v1/contacts/groups then returns 404 responses. However POST and PUT requests still work.

The fix for this is changing the order. If I put the contacts api resource below the route group, it then works.

$router->group(['prefix' => '/v1', 'middleware' => ['auth:api']], function ($router) {
    $router->group(['prefix' => '/contacts'], function ($router) {
        $router->apiResource('/groups', 'Contacts\\GroupsController');
    });

    $router->apiResource('/contacts', 'ContactsController');
});

Is this intended behaviour? It seems strange that in the first case POST and PUT requests work, but GET requests return 404 responses.

Using $router->apiResource('/contacts', 'ContactsController'); will register the ContactsControllers actions index, show, store, update and destroy for routes.
For the show action it registers /v1/contacts/{contact}. Because this route is ahead of /v1/contacts/groups, the route will match the ContactsControllers route and use 'groups' for the wildcard.

Thanks @SPie - makes sense.
