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"}

C#

bool success = false;

Chilkat.Http http = new Chilkat.Http();
success = false;

Chilkat.JsonObject json = new Chilkat.JsonObject();

//  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.
string url = "https://chilkatsoft.com/echo_request_body.asp";

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

Debug.WriteLine("Response Status Code: " + Convert.ToString(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.
Debug.WriteLine(http.LastHeader);
Debug.WriteLine(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"}
