App::setLocale();Set the language configuration file

Language configuration file config/app.php

locale is the default language, fallback_locale is the backup language

The language string is stored in the resources/lang directory, and the Blade template engine prints the language line {{ trans('messages.welcome') }}

The idea is

Save the current language setting in the Session, and then write a Middleware to intercept the Http request, and use the language setting value in the Session to set the Locale in the intercepted request. .
