CORS header ‘Access-Control-Allow-Origin’ missing in servant
问题 using the run from Network.Wai.Handler.Warp function to server rest api run :: Port -> Application -> IO () but while doing post request, getting an error CORS header ‘Access-Control-Allow-Origin’ . any idea how to overcome this in servant/haskell 回答1: You could use wai-cors middleware to add CORS headers. At the end you'll have something like app = simpleCors $ serve api serverImpl where simpleCors is a Middleware from wai-cors serve turns servant handlers into wai Application api :: Proxy
