如何在Laravel中进行变量/通配符路由? [英] How can I do variable/wildcard routes in Laravel?

问题描述

我正在使用Laravel 5，并且需要执行通配符路由，根据从数据库中提取的URL类型将用户发送到其他控制器.

I am using Laravel 5 and need to do a wildcard route, sending the user to different controllers based on the URL type, pulled in from the database.

我需要检查数据库中的URL slug，然后根据数据库中保存的slug类型加载相关的控制器/方法.我正在为最后一部分而苦苦挣扎，这是将用户发送到相关的控制器.以下是我的路线:

I need to check the URL slug in the database, and then load the relevant controller/method based on the slug type, held in the database. I am struggling with the final part, which is sending the user to the relevant controller. Below is my route:

Route::any('{slug}', function($slug){
    $url = \App\Url_slug::where('url_slug', $slug)->first();
    if($url->count()){
        switch($url->url_type){
            case 'product':
                // SEND USER TO PRODUCT CONTROLLER
                break;
            case 'category':
                // SEND USER TO CATEGORY CONTROLLER
                break;
            case 'page':
                // SEND USER TO PAGE CONTROLLER
                break;
        }
    } else {
        abort(404);
    }
});

为了将用户发送到相关控制器，我需要用什么替换注释?

What do I need to replace the comments with in order the send the user to the relevant controller?

推荐答案

为此，您需要加载app()的实例，然后调用make('Controller')方法和callAction.下方的完整路线:

To do this, you need to load an instance of app() and then call make('Controller') method as well as callAction. Full route below:

Route::any('{slug}', function($slug){
    $url = \App\Url_slug::where('url_slug', $slug)->first();
    if($url->count()){
        $app = app();

        switch($url->url_type){
            case 'product':
                $controller = $app->make('App\Http\Controllers\ProductController');
                break;
            case 'category':
                $controller = $app->make('App\Http\Controllers\CategoryController');
                break;
            case 'page':
                $controller = $app->make('App\Http\Controllers\PageController');
                break;
        }
        return $controller->callAction('view', ['url_slug' => $url->url_slug, 'url_slug_id' => $url->id]);
    } else {
        abort(404);
    }
});
