I tried using ngrok

Overview

This is the third post for a new graduate. I had the opportunity to use ngrok and found it very convenient, so I will write how to use it. ngrok is a tool that allows you to access the server launched on localhost from the outside. This time I launched localhost with Go and tried to access localhost from my personal smartphone.

install ngrok

After registering as a user from the Official Site, download the zip file and unzip it. You can use github or google account for user registration. After unzipping, start ngrok.exe and type in the command.

ngrok http 8080

If you see the following display, you are done. You can access localhost: 8080 from the external environment with https://66336728576f.ngrok.io.

Actually access from the outside

package main

import (
	"fmt"
	"net/http"
)

func main() {
	http.HandleFunc("/", handler)
	http.ListenAndServe(":8080", nil)
}
func handler(w http.ResponseWriter, r *http.Request) {
	fmt.Fprint(w, "ngrok super convenient")
}

When I accessed https://66336728576f.ngrok.io from my personal smartphone, ngrok super convenient was displayed! ngrok It's convenient.
