JavaScript

var success = false;

var http = new CkHttp();
success = false;

var json = new CkJsonObject();

// Build the following JSON:  {"greeting":"Hello World"}
json.UpdateString("greeting","Hello World");

// This URL echoes the contents of the request body, letting us view it.
var url = "https://chilkatsoft.com/echo_request_body.asp";

// Send a POST with the JSON in the HTTP request body.
var resp = new CkHttpResponse();
success = http.HttpJson("POST",url,json,"application/json",resp);
if (success == false) {
    console.log(http.LastErrorText);
    return;
}

console.log("Response Status Code: " + resp.StatusCode);

// Examine the request we sent.
// The LastHeader property stores the HTTP request header of the most recent request sent,
// and in this instance, the response body mirrors the request body.
console.log(http.LastHeader);
console.log(resp.BodyStr);

// Output:

// POST /echo_request_body.asp HTTP/1.1
// Host: chilkatsoft.com
// Accept: */*
// Accept-Encoding: gzip
// Content-Type: application/json
// Content-Length: 26
// 
// {"greeting":"Hello World"}
