Laravel中命名路由的一些用例是什么？

Question

After reading the documentation, I still only have a vague idea of what Named Routes are in Laravel.

Could you help me understand?

Route::get('user/profile', function () {
    //
})->name('profile');

Route::get('user/profile', 'UserProfileController@show')->name('profile');

It says:

Once you have assigned a name to a given route, you may use the route's name when generating URLs or redirects via the global route function

I don't understand what the second part of the sentence means, about generating URLs or redirects.

What would be a generated URL in the case of profile from the above example? How would I use it?

The best resource is right here : https://laravel.com/docs/5.8/routing#named-routes

One of the common use case is in your views. Say your post request goes to a particular route, basically without named routes you can simply go like this to store a task

action="/task"

but say for example you need to update the route to /task/store , you will need to update it everywhere you use the route.

But consider you used a named route

Route::post('/task', 'TaskController@store')->name('task.store'); 

With named routes you can use the route like this in your view:

action="{{route('task.store')}}"

Now if you choose to update your route, you only need to make the change in the routes file and update it to whatever you need.

Route::post('/task/now/go/here', 'TaskController@store')->name('task.store');

If you need to pass arguments to your routes, you pass it as arguments to route helper like this:

route('task.edit', 1), // in resource specific example it will output /task/1/edit 

All of the view examples are given you use blade templating.
