Is it possibly to modify the request before being processed by the routes file?

Basically the app I am looking to build will have hundreds of slug URLs. But the slugs will lead to different controllers. To achieve this I will keep key:values pairs in redis.

For example:

// slug = domain.com/slug-one
// Would route to
Route::get('pages/{id}', 'PagesController@index');

// slug = domain.com/slug-two
// Would route to
Route::get('articles/{id}', 'ArticlesController@index');

For me the best way would be to modify the request in the before filter in filters.php

App::before(function($request)
{
    // Do Redis Lookup.  If match change request path
    $request->path = "$controller/$id";
});

Hope you can advise.

回答1:

You can't change a request routes in a filter because filters are applied AFTER the route is resolved.

One way would be to define a route like that:

Route::get('/{$request}', 'PagesController@slugRedirect');

Then inside the slugRedirect you do your redis lookup then call (or redirect with 301) the correct controller like that:

// Create a new separate request
$request = Request::create('/articles/1', 'GET');
// Dispatch the new request to a new route
$response = Route::dispatch($request);
// Fetch the response (in your case, return it)

I haven't tested that, please let me know if it work or not.
