如何在Laravel中获得该路线的结构

Let's say I have the following route in Laravel:

Route::get('posts/{post}/comments/{comment}', function ($postId, $commentId) {
    //
});

And let's say I'm on the following url: posts/3/comments/54

I can get the url as a string by accessing the url() method, this would give me back the exact url.

In my case, I need something else. Is there a way to get the route's structure? I want to do something like this:

if(someUrlStructureFunction() == "posts/{post}/comments/{comment}") //do something

Thanks!

When using resources, the actions have names by default, so your post comments could be:

Route::resource('posts.comments', 'PostsCommentsController');

php artisan route:list
+--------+-----------+----------------------------------------+------------------------+------------------------------------------------------+------------+
| Domain | Method    | URI                                    | Name                   | Action                                               | Middleware |
+--------+-----------+----------------------------------------+------------------------+------------------------------------------------------+------------+
|        | GET|HEAD  | posts/{posts}/comments                 | posts.comments.index   | App\Http\Controllers\PostsCommentsController@index   |            |
|        | POST      | posts/{posts}/comments                 | posts.comments.store   | App\Http\Controllers\PostsCommentsController@store   |            |
|        | GET|HEAD  | posts/{posts}/comments/create          | posts.comments.create  | App\Http\Controllers\PostsCommentsController@create  |            |
|        | GET|HEAD  | posts/{posts}/comments/{comments}      | posts.comments.show    | App\Http\Controllers\PostsCommentsController@show    |            |
|        | PUT|PATCH | posts/{posts}/comments/{comments}      | posts.comments.update  | App\Http\Controllers\PostsCommentsController@update  |            |
|        | DELETE    | posts/{posts}/comments/{comments}      | posts.comments.destroy | App\Http\Controllers\PostsCommentsController@destroy |            |
|        | GET|HEAD  | posts/{posts}/comments/{comments}/edit | posts.comments.edit    | App\Http\Controllers\PostsCommentsController@edit    |            |

Then you could use Request::route()->getName() to analyze which one was called.

Give your route a name:

Route::get('user/profile', 'UserController@showProfile')->name('profile');

^{(That's the Laravel 5.3 syntax. It's slightly different in earlier versions.)}

then, you can use:

Request::route()->getName()

to check if you're on that route.

Based on your comment you want to restrict certain routes to specific roles

you can try using route groups then create a middleware for each roles: https://laravel.com/docs/5.3/routing#route-groups

//put your admin routes inside this
Route::group(['middleware' => 'admins'], function () {
    Route::get('posts/{post}/comments/{comment}', function ($postId, $commentId) {
        //
    });
});

//put your users routes inside this
Route::group(['middleware' => 'users'], function () {
    Route::get('posts/{post}/comments/{comment}', function ($postId, $commentId) {
            //
    });
});
