Map a local Web service to an external network using Ngrok

Why use Ngrok?

As a web developer, we sometimes need to temporarily deploy a local Web site to an extranet for people to experience evaluation or assist in debugging, and so on, and we usually do this:

1. Find a Web server running on an external network
2. The server has the environment which the website needs, otherwise builds itself
3. Deploy a Web site to a server
4. After debugging, remove the Web site from the server

Just want to show a friend of the site, to not so troublesome, tired feeling not love ╰ ('-′) ╯

After the Ngrok, the world is so beautiful.
