Ngrok 搭配Golang Web 對外開Port

— — —

package main

import (
 "fmt"
 "log"
 "net/http"
)

func tryHandle(writer http.ResponseWriter, req *http.Request){
 
 writer.WriteHeader(http.StatusOK)
 fmt.Print(" hello .\n")
   // fmt.Fprintf("hello %s")
 fmt.Fprintf(writer,"hello"); // 是個interface 把資料帶到畫面上
}
func main() {
 http.HandleFunc("/", tryHandle)
 err := http.ListenAndServe(":8080", nil)
 // port 號要符合規範
 if err != nil {
  log.Fatal("ListenAndServe: ", err)
 }
}

localhost:8080

ngrok http 8080
