Hello @roderick-liu, this is happening because you've tried to install the stable version with the $ go mod init myapp
$ go get github.com/kataras/iris/v12@master
$ go get github.com/iris-contrib/middleware/cors@masterExample Appserver package main
import (

)
func main() {
app := iris.New()
crs := cors.New(cors.Options{
AllowedOrigins: []string{"*"}, // allows everything, use that to change the hosts.
AllowCredentials: true,
})
/* OR just:
crs := func(ctx iris.Context) {
ctx.Header("Access-Control-Allow-Origin", "*")
ctx.Header("Access-Control-Allow-Credentials", "true")
if ctx.Method() == iris.MethodOptions {
ctx.Header("Access-Control-Methods", "POST, PUT, PATCH, DELETE")
ctx.Header("Access-Control-Allow-Headers", "Access-Control-Allow-Origin,Content-Type")

ctx.StatusCode(iris.StatusNoContent)
return
}
ctx.Next()
