php - Laravel 5 Route::resource 嵌套 Route::group

Question

此结构适用于(所有 GET):/dashboard/video、/dashboard/video/element、/dashboard/video/create >,/dashboard/video/element/create、/dashboard/video/element/{id}，但不适用于 /dashboard/video/{id} .

换句话说，show($id) 不会被 /dashboard/video/{id} 调用。

知道为什么吗？

Route::group(['prefix' => 'dashboard', 'middleware' => ['csrf', 'auth']], function () {

    Route::group(['prefix' => 'video'], function() {

        // non-standard delete: sends array of ids in request body
        Route::delete('/', 'InteractiveVideoController@destroyMany');
        Route::resource('/', 'InteractiveVideoController');

        Route::resource('element', 'InteractiveElementController');
    });
...
});

执行时问题会变得很明显

php artisan route:list

从生成的表中您可以看到:

|        | GET|HEAD                       | dashboard/video                                       | dashboard.video..index   | App\Http\Controllers\InteractiveVideoController@index      |            |
|        | GET|HEAD                       | dashboard/video/create                                | dashboard.video..create  | App\Http\Controllers\InteractiveVideoController@create     |            |
|        | POST                           | dashboard/video                                       | dashboard.video..store   | App\Http\Controllers\InteractiveVideoController@store      |            |
|        | GET|HEAD                       | dashboard/video/{}                                    | dashboard.video..show    | App\Http\Controllers\InteractiveVideoController@show       |            |
|        | GET|HEAD                       | dashboard/video/{}/edit                               | dashboard.video..edit    | App\Http\Controllers\InteractiveVideoController@edit       |            |
|        | PUT                            | dashboard/video/{}                                    | dashboard.video..update  | App\Http\Controllers\InteractiveVideoController@update     |            |
|        | PATCH                          | dashboard/video/{}                                    |                          | App\Http\Controllers\InteractiveVideoController@update     |            |
|        | DELETE                         | dashboard/video/{}                                    | dashboard.video..destroy | App\Http\Controllers\InteractiveVideoController@destroy    |            |

正如您所见，在视频组下将视频路由定义为 / 是行不通的，因为为了资源 Controller 创建带参数的静态路径，它使用路径的第一部分作为变量名。在您的情况下，它是空的(只是一个被删除的斜杠 /)，这就是您得到这个 {} 的原因。

您必须更改您的routes.php并将视频资源移出组，它将起作用，如下所示:

Route::group(['prefix' => 'dashboard'], function () {

    Route::group(['prefix' => 'video'], function() {

        Route::resource('element', 'InteractiveElementController');
    });

    // non-standard delete: sends array of ids in request body
    Route::delete('video', 'InteractiveVideoController@destroyMany');
    Route::resource('video', 'InteractiveVideoController');

});

您必须将视频资源放在 video 元素下，否则 video/element 将永远不会匹配，因为定义的路由顺序很重要。

这对您有用，现在所有页面都将正常打开。您还可以通过再次执行来检查路由是否正确定义:

php artisan route:list
