HTTP – the basics of the GET and POST methods

Hypertext Transfer Protocol (HTTP) allows a client (for example, the web browser) to interact with a server (our application).

curl -X GET url_path?name1=value1&name2=value2

After the ? symbol, the name/value pair specifies which data to query, and they are separated by a & symbol.

The way a client transfers data to the server is called POST, and the data is in the body of the call:

curl -X POST  -d @datafile.txt url_path
