Laravel 显式路由模式绑定在某些情况下不起作用？

Question

I am using Laravel 8 and explicit route mode binding in my project to call an product under the slug instead of the id . I have products, posts and etc, which are all using explicit route mode binding with the slug in the database instead of the id .

What really confuses me is that the explicit route mode binding is working everywhere but not with products . Here is my RouteServiceProvider:

// Change route for product from $id to $slug
Route::bind('product', function ($value) {
    return Product::where('slug', $value)->first() ?? abort(404);
});

// Change route for user from $id to $name
Route::bind('user', function ($value) {
    return User::where('name', $value)->first() ?? abort(404);
});

// Change route for product from $id to $slug
Route::bind('post', function ($value) {
    return Post::where('slug', $value)->first() ?? abort(404);
});

Here are some example routes for a user , a product and a post :

works:      Route::get('/product/{productType}/{product}', ['as' => 'product.show', 'uses' => 'ProductController@show']);     
404 error:  Route::post('product/{product}/like', ['as' => 'product.like', 'uses' => 'LikeController@likeProduct']);          
404 error:  Route::post('product/{product}/dislike', ['as' => 'product.dislike', 'uses' => 'LikeController@dislikeProduct']); 
404 error:  Route::post('product/{product}/mark', ['as' => 'product.mark', 'uses' => 'ProductController@markProduct']);

works:      Route::get('user/{user}', ['as' => 'user.show', 'uses' => 'UserController@show']);
works:      Route::post('user/{user}/update/password', ['as' => 'user.password.change', 'uses' => 'UserController@updatePassword']);

works:      Route::get('/blog/{postCategory}/{post}', ['as' => 'post.show', 'uses' => 'PostController@show']);

When I do a dd for the value in the RouteServiceProvider for user , product and post I can figure out what's the problem here. All values do dump the actual slug of the resource. Even the get request for a product is the actual slug . However, when performing an post request for a product , I always get the end of the url as value. Of course this leads to a 404 .

For example the route product/{product}/mark with an post requests does dump mark as value and not the slug of the product... why is that? All other post requests work fine!

I also tried switch a route from a post method to a get method but same result here... also an 404 error and I get mark as value again...

Can anybody explain whats the problem here and why it is not working?

When I change product/{product}/mark to produkt/{product}/mark it is working. But why? and why is '/product/{productType}/{product}' working? That is really strange..

Kind regards and thank you!

我现在已经删除了RouteServiceProvider更改，并且我正在使用自 Laravel 8 以来提供的此功能。问题解决了......我不知道问题是什么......
