// Package auth provides handlers to enable basic auth support.
// Simple Usage:
//	import(
//		"github.com/beego/beego/v2"
//		"github.com/beego/beego/v2/server/web/filter/auth"
//	)
//
//	func main(){
//		// authenticate every request
//		beego.InsertFilter("*", beego.BeforeRouter,auth.Basic("username","secretpassword"))
//		beego.Run()
//	}
//
//
// Advanced Usage:
//
//	func SecretAuth(username, password string) bool {
//		return username == "astaxie" && password == "helloBeego"
//	}
//	authPlugin := auth.NewBasicAuthenticator(SecretAuth, "Authorization Required")
//	beego.InsertFilter("*", beego.BeforeRouter,authPlugin)
