var
success: Boolean;
http: HCkHttp;
req: HCkHttpRequest;
resp: HCkHttpResponse;
requestBody: PWideChar;

begin
success := False;

http := CkHttp_Create();
req := CkHttpRequest_Create();
resp := CkHttpResponse_Create();

//  Specify the details of the HTTP request.
CkHttpRequest_putHttpVerb(req,'POST');
CkHttpRequest_putContentType(req,'application/json');
CkHttpRequest_putPath(req,'/echo_request_body.asp');

requestBody := '{"greeting":"Hello World"}';
CkHttpRequest_LoadBodyFromString(req,requestBody,'utf-8');

//  Send a POST to https://chilkatsoft.com/echo_request_body.asp with a JSON request body.
success := CkHttp_HttpSReq(http,'chilkatsoft.com',443,True,req,resp);
if (success = False) then
  begin
    Memo1.Lines.Add(CkHttp__lastErrorText(http));
    Exit;
  end;

Memo1.Lines.Add('Response Status Code: ' + IntToStr(CkHttpResponse_getStatusCode(resp)));

//  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.
Memo1.Lines.Add(CkHttp__lastHeader(http));
Memo1.Lines.Add(CkHttpResponse__bodyStr(resp));

//  Output:

//  Host: chilkatsoft.com
//  Content-Type: application/json
//  Content-Length: 26
//  
//  {"greeting":"Hello World"}

CkHttp_Dispose(http);
