Dart

Example: Http.SetCookieXml method

Demonstrates the SetCookieXml method. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final http = CkHttp();

  http.saveCookies = true;
  http.cookieDir = 'c:/temp/cookie_cache';
  // For this initial request, we are not sending cookies.
  // We are starting a new (cookie) session and saving the cookies we receive.
  http.sendCookies = false;

  // Do a request that establishes and saves cookies in files in the cookie directory.
  var html = http.quickGetStr('https://google.com/');

  // Examine the LastResponseHeader to see the cookies that were received:
  print(http.lastResponseHeader);
  print('----------------------------------');

  // We can see the following Set-Cookie response header fields:

  // Set-Cookie: AEC=AVh_V2h-fsL2-****; expires=Mon, 23-Feb-2026 19:15:10 GMT; path=/; domain=.google.com; Secure; HttpOnly; SameSite=lax
  // Set-Cookie: NID=525=XC_cL****Hn7-WONX; expires=Thu, 26-Feb-2026 19:15:10 GMT; path=/; domain=.google.com; HttpOnly

  // The following file was created:  c:/temp/cookie_cache/google_com.xml

  // Examine the cookies received in the above request.
  print(http.getCookieXml('google.com'));
  print('----------------------------------');

  // Sample output.

  // <?xml version="1.0" encoding="utf-8"?>
  // <cookies>
  //     <cookie key=".google.com,/,AEC" v="0" expire="Mon, 23-Feb-2026 19:05:20 GMT" secure="yes">
  //         <AEC>AVh_V2gL8QzTdFGYq6_rS6ktBfqm8WNG3pzHxS2nTZD5i23dRBau2c4ZRA</AEC>
  //     </cookie>
  //     <cookie key=".google.com,/,NID" v="0" expire="Thu, 26-Feb-2026 19:05:20 GMT">
  //         <NID>525=SuLcnaSkFqF4Jz_jLEq4kt_f3MY2Xro1VDoVzLKvp8XHcW2UHuLKJSr55iDeW0NiRIPXoAwJWF1-YNl29unX2xfhEWsS5BhbuK_2DXdD9cTOmn5BSENMhZasxeJ71mEP2PQRMXBndqnl41DhblC2jjdac_so4TESIll1B0GCVe9wRFjqI6DTZItRCj61BHmr1_RAQi0_jrh_ihn6KYtIFEY7</NID>
  //     </cookie>
  // </cookies>

  // -------------------------------------------------------------------------------------------
  // Let's say we want to continue with the session at some later time with a new HTTP object.
  // One way to do it is to simply set the same cookie properties:
  final httpB = CkHttp();

  httpB.saveCookies = true;
  httpB.cookieDir = 'c:/temp/cookie_cache';
  httpB.sendCookies = true;

  // The cookies from the cache are sent.
  html = httpB.quickGetStr('https://google.com/');

  // Examine the LastHeader to see the contents of the Cookie header field.
  print(httpB.lastHeader);
  print('----------------------------------');

  // -------------------------------------------------------------------------------------------
  // Another way to do it is to explicitly load the cookies from XML
  // and set the cookies for the particular domain.

  final httpC = CkHttp();

  httpC.saveCookies = true;
  // Do not save cookies to files, just keep them in memory.
  httpC.cookieDir = 'memory';
  httpC.sendCookies = true;

  final sbCookiesXml = CkStringBuilder();
  try {
    sbCookiesXml.loadFile('c:/temp/cookie_cache/google_com.xml', 'utf-8');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  try {
    httpC.setCookieXml('google.com', sbCookiesXml.getAsString());
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  html = httpC.quickGetStr('https://google.com/');

  // Examine the LastHeader to see the contents of the Cookie header field.
  print(httpC.lastHeader);
}
