func chilkatTest() {
    var success: Bool = false

    let http = CkoHttp()!
    success = false

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

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

    let json = CkoJsonObject()!
    json.update("name", value: "Harry")
    json.update("state", value: "FL")

    // Specify the details of the request
    let req = CkoHttpRequest()!

    req.httpVerb = "POST"
    req.contentType = "application/json"
    req.loadBody(from: json.emit(), charset: "utf-8")

    // Send the charset attribute in the HTTP request header.
    req.sendCharset = true
    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).

    let resp = CkoHttpResponse()!
    success = http.httpReq("https://www.chilkatsoft.com/echo_request_body.asp", request: req, response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    // Examine the HTTP request header we sent:
    print("\(http.lastHeader!)")

    // The response body contains the raw content of the HTTP request body we sent.
    print("\(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"}
