laravel Route 用法

Route::group([
    "prefix" => "admin", 
    "middleware" => ["permission:manage-admins"], 
    "domain" => "{account}.myapp.com",
    "namespace" => "Admin"
], function() {
    Route::get("/", "AdminController@welcome");
    Route::get("/manage", [
        "middleware" => ["permission:manage-admins"], 
        "uses" => "AdminController@manageAdmins"],
        "namespace" => "User"
    );
});
