Question

我正在尝试为特定网站制作一个Web爬网程序API，该网站的登录名后面有一些资源，登录名在Cookies中提供了会话ID。当我尝试发布登录信息时，会话ID未保存到CookieJar。

代码：

var dio = new Dio()
..interceptors.add(CookieManager(CookieJar()));

login(String username, String password) async{

    (dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate = (client) { client.badCertificateCallback = (X509Certificate cert, String host, int port) => true; return client; };
    var response1 =await dio.post("https://www.codestepbystep.com/login", data:{"usernameoremail": username, "password":password, "login":"Login", "userkeepmeloggedin":"on", "after" : "after", "timezone" : "America/Chicago", "timezoneoffset" : "-360"});
    debugPrint(response1.headers.toString());
    var response = await dio.get("https://www.codestepbystep.com/problem/view/c/basics/hello_world");
    debugPrint(response.headers.toString());
  }

POST标头：

I/flutter (11736): set-cookie: JSESSIONID=60C35F7306479DCC3A6E33C675D05995; Path=/; Secure; HttpOnly

获取标题：

I/flutter (11736): content-type: text/html;charset=ISO-8859-1
I/flutter (11736): cache-control: no-cache
I/flutter (11736): date: Wed, 04 Sep 2019 22:25:26 GMT

由于任何原因，由于未保存cookie，因此cookie不会出现在GET标头中。我尝试从POST复制标头并在GET请求中使用它们，但仍然无法从GET访问网站上的特定资源。如何获取cookie以正确保存？

无法从Dio和CookieJar保存会话ID的Cookie
