This code sets up a basic HTTP proxy server using the http-proxy module in Node.js.

First, we import the necessary modules http and http-proxy.

Then, we create an instance of httpProxy using the createProxyServer() method.

Next, we create an HTTP server using http.createServer(). Inside the server callback function, we use the proxy.web() method to forward the incoming request (req) and response (res) to the target server specified by the target option. In this case, the target server is http://ihrm.itheima.net/api.

Finally, we listen on port 8000 for incoming requests by calling the listen() method on the HTTP server
