如何在Laravel中设置动态路由前缀？

Question

I need to create an app with multiple locales. And each route is prefixed with the locale. For example, xxx.com/en/home, xxx.com/fr/home.

The thing is, I need to dynamically bind the locale string to route prefix. Since users can change locale, the locale string is stored in session. And I need reference to the session on web.php. Session object can't be used in the globle scope on web.php, meaning session('key') won't get you anything (null) in the outermost scope except in route functions because Laravel parses web.php before instantiating any session object, I think. Therefore I face a conundrum in that I can't reference session in the outermost scope on web.php while I need session to create dynamic prefix. How can I solve this?

I recently prefixed my routes with locale and I found it pretty easy to implement using mcamara's Laravel Localization package. After setting up the package installation, I just had to add a route group for all the URLs I wanted with locale prefix.

Route::group([
    'prefix' => LaravelLocalization::setLocale(),
    'middleware' => ['localeSessionRedirect', 'localizationRedirect']
], function()
{
   Route::get('/contact', 'HomeController@contact_page');
});
