Laravel 中间件 except除外规则不起作用

我在构造函数中有一个包含以下内容的控制器:

$this->middleware('guest', ['except' =>
    [
        'logout',
        'auth/facebook',
        'auth/facebook/callback',
        'auth/facebook/unlink'
    ]
]);

The 'logout' rule (which is there by default) works perfectly but the other 3 rules I have added are ignored. The routes in routes.php look like this:

Route::group(['middleware' => ['web']],function(){

    Route::auth();

    // Facebook auth
    Route::get('/auth/facebook', 'Auth\AuthController@redirectToFacebook')->name('facebook_auth');
    Route::get('/auth/facebook/callback', 'Auth\AuthController@handleFacebookCallback')->name('facebook_callback');
    Route::get('/auth/facebook/unlink', 'Auth\AuthController@handleFacebookUnlink')->name('facebook_unlink');
}

If I visit auth/facebook, auth/facebook/callback or auth/facebook/unlink whilst logged in I get denied by the middleware and thrown back to the homepage.

我已经try 使用/指定"例外"规则，以便它们与routes.php中的路由完全匹配，但没有什么不同.你知道为什么这些规则被忽略了，而默认的"注销"规则却被尊重了吗？

干杯！
