如何在laravel5.2中设置基本路径？

I am new one to laravel, how can we set base URL in laravel

I want url looks like https://localhost/projectfolder/site/home

But when i click on link it goes to

https://localhost/home

Thanks in advance

APP_ENV=local
APP_DEBUG=true
APP_KEY=SomeRandomString
APP_URL='this is where you set the app url'

You can find this settings in the .env file in your root project folder.
