Question

我有这样的路线：

$this->get('/{citySlug}/{catSlug1?}/{catSlug2?}/{sightSlug?}', function () {
  return 'Hello World';
});

如何在 RouteServiceProvider.php 的boot（）函数中绑定它来检查？

我试试这个：

Route::bind('citySlug', function ($citySlug, $route) { ... });

   Route::bind('catSlug1', function ($citySlug, $route) { ... });

   Route::bind('catSlug2', function ($catSlug2, $route) { ... });

   Route::bind('catSlug3', function ($catSlug3, $route) { ... });

   Route::bind('sightSlug', function ($sightSlug, $route) { ... });

但可选参数错误......上面有什么问题？

更新

example.com/city_slug/cat1/cat2  It works.

example.com/city_slug/cat1/cat2/sight_slug It works.

example.com/city_slug/cat1/sight_slug It not works!

绝对不行。尝试了解您正在使用的路线： -

$this->get('/{citySlug}/{catSlug1?}/{catSlug2?}/{sightSlug?}', function () {
    return 'Hello World';
});
citySlug i.e. mandatory according to your route
catSlug1,catSlug2,sightSlug i.e this is not manadtory because you added question mark as per laravel documentation

现在您可以尝试访问此网址： -

example.com/city_slug/cat1/sight_slug --- Definitely it will not work because
                                          your **sight_slug** is treat like **catSlug2** 
                                          that's why its not working

<强>解决方案： -

For this you can use $_GET parameters and create one route something like that:-
$this->get('/filter-query', function () {
   return 'Hello World';
});

现在您的网址将如下所示： -

example.com/filter-query?citySlug=cityname&cat1=catvalue&cat2=&sightSlug=sightslugvalue

在功能之后，您可以回显$ _GET，您的问题将得到解决。希望它有所帮助！
