Send a REST Request with a Text Body

See more REST Examples

Demonstrates Rest.FullRequestString, a convenience method that sends a complete request whose text body (such as JSON, XML, or plain text) is supplied directly, then reads and returns the response body as text.

var
success: Boolean;
rest: HCkRest;
bTls: Boolean;
bAutoReconnect: Boolean;
jsonBody: PWideChar;
responseText: PWideChar;

begin
success := False;

rest := CkRest_Create();
bTls := True;
bAutoReconnect := True;
success := CkRest_Connect(rest,'example.com',443,bTls,bAutoReconnect);
if (success = False) then
  begin
    Memo1.Lines.Add(CkRest__lastErrorText(rest));
    Exit;
  end;

//  Send a complete request whose text body is supplied directly, such as JSON.  The response body is
//  read as text and returned.  The 1st argument is the HTTP verb, the 2nd is the URI path, and the
//  3rd is the request body.
CkRest_AddHeader(rest,'Content-Type','application/json');

jsonBody := '{ "name": "example", "active": true }';
responseText := CkRest__fullRequestString(rest,'POST','/api/items',jsonBody);
if (CkRest_getLastMethodSuccess(rest) = False) then
  begin
    Memo1.Lines.Add(CkRest__lastErrorText(rest));
    Exit;
  end;
Memo1.Lines.Add(responseText);

CkRest_Dispose(rest);
