Error in accessing laravel api routes (Blocked by CORS policy)

My laravel version is 5.6.40.When i am accessing laravel api, it says Access to XMLHttpRequest at from origin has been blocked by CORS policy. I tried barryvdh and fruitcake packages.But always pops up same error.Api is working fine in local machine but gets error from remote server. What is the solution?
