HTTP Post

You probably already figured this out (or knew), but curl is a command line tool for making HTTP requests. If you cat the /tmp/rawget.http file that we created, you should have something very similar to this:

GET /goodies HTTP/1.1
Host: localhost:42069
User-Agent: curl/8.6.0
Accept: */*

This is what a raw HTTP message looks like - specifically a raw HTTP GET request.

Request line: GET /goodies HTTP/1.1
Headers: Host: localhost:42069, User-Agent: curl/8.6.0, Accept: */*
Body: (empty)

Let's see what a raw HTTP POST request (with a body) looks like...

Assignment

Run your tcplistener program from the root of your project and redirect the output to a temporary file:
```
go run ./cmd/tcplistener | tee /tmp/rawpost.http
```
In another shell, send a POST request to it:
```
curl -X POST -H "Content-Type: application/json" -d '{"flavor":"dark mode"}' http://localhost:42069/coffee
```
Again, this time your cURL command will hang, but this time, you might notice that the body ({"flavor":"dark mode"}) isn't showing up yet in the tcplistener output... and that's because it doesn't end with a newline.
Kill the cURL command and your tcplistener should finally flush the rest of the request to the terminal.
Kill your tcplistener program.

Run and submit the CLI tests.
