BOOL success = NO;

CkoHttp *http = [[CkoHttp alloc] init];
success = NO;

// This example will send an HTTP POST with the body of the HTTP request containing JSON.

// Create the following JSON: { "name": "Harry", "state": "FL" }

CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json UpdateString: @"name" value: @"Harry"];
[json UpdateString: @"state" value: @"FL"];

// Specify the details of the request
CkoHttpRequest *req = [[CkoHttpRequest alloc] init];

req.HttpVerb = @"POST";
req.ContentType = @"application/json";
[req LoadBodyFromString: [json Emit] charset: @"utf-8"];

// Send the charset attribute in the HTTP request header.
req.SendCharset = YES;
req.Charset = @"utf-8";

// Send the POST
// You can send the POST to the URL below.  
// The response will contain the raw body of the request that was sent.
// (i.e. everything except the HTTP request header).

CkoHttpResponse *resp = [[CkoHttpResponse alloc] init];
success = [http HttpReq: @"https://www.chilkatsoft.com/echo_request_body.asp" request: req response: resp];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

// Examine the HTTP request header we sent:
NSLog(@"%@",http.LastHeader);

// The response body contains the raw content of the HTTP request body we sent.
NSLog(@"%@",resp.BodyStr);

// Sample output:

// POST /echo_request_body.asp HTTP/1.1
// Host: www.chilkatsoft.com
// Content-Type: application/json; charset=utf-8
// Content-Length: 29
// 
// 
// {"name":"Harry","state":"FL"}
