Sample code:
//Processing Code
import http.requests.*;
GetRequest get = new GetRequest("https://httpbin.org/ip");
get.send();
println("Reponse Content: " + get.getContent());
println("Reponse Content-Length Header: " + get.getHeader("Content-Length"));
result:
Reponse Content: {
"origin": "203.85.99.9"
}
Reponse Content-Length Header: 30
Sample code2:
/**
* HTTP Client.
*
* Starts a network client that connects to a server on port 80,
* sends an HTTP 1.0 GET request, and prints the results.
*
* Note that this code is not necessary for simple HTTP GET request:
* Simply calling loadStrings("http://www.processing.org") would do
* the same thing as (and more efficiently than) this example.
* This example is for people who might want to do something more
* complicated later.

result:
