Accept: */*
Accept-Encoding: gzip
Content-Type: application/json
Content-Length: 26

{"greeting":"Hello World"}

C++

#include <CkHttp.h>
#include <CkJsonObject.h>
#include <CkHttpResponse.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkHttp http;
    success = false;

    CkJsonObject json;

    //  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.
    const char *url = "https://chilkatsoft.com/echo_request_body.asp";

    //  Send a POST with the JSON in the HTTP request body.
    CkHttpResponse resp;
    success = http.HttpJson("POST",url,json,"application/json",resp);
    if (success == false) {
        std::cout << http.lastErrorText() << "\r\n";
        return;
    }

    std::cout << "Response Status Code: " << resp.get_StatusCode() << "\r\n";

    //  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.
    std::cout << http.lastHeader() << "\r\n";
    std::cout << resp.bodyStr() << "\r\n";

    //  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"}
