See more REST Examples

Demonstrates how to send a POST with query params (x-www-form-urlencoded) using the Chilkat REST object. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final rest = CkRest();

  // This example will send to https://www.chilkatsoft.com/echoPost.asp

  // Make the initial connection (without sending a request yet).
  final bTls = true;
  final port = 443;
  final bAutoReconnect = true;
  try {
    rest.connect('www.chilkatsoft.com', port, bTls, bAutoReconnect);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Provide query params.
  rest.addQueryParam('firstName', 'John');
  rest.addQueryParam('lastName', 'Doe');
  rest.addQueryParam('company', 'Bisco Bits Ltd.');

  final String responseStr;
  try {
    responseStr = rest.fullRequestFormUrlEncoded('POST', '/echoPost.asp');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // When successful, the response status code will equal 200.
  if (rest.responseStatusCode != 200) {
    // Examine the request/response to see what happened.
    print('response status code = ${rest.responseStatusCode}');
    print('response status text = ${rest.responseStatusText}');
    print('response header: ${rest.responseHeader}');
    print('response body (if any): $responseStr');
    print('---');
    print('LastRequestStartLine: ${rest.lastRequestStartLine}');
    print('LastRequestHeader: ${rest.lastRequestHeader}');
    return;
  }

  print(responseStr);
  print('Success.');
