Dio dart/Flutter 获取和设置 cookie

Question

I would like to do a set cookies, do a get request and after get the cookies. In python it will be this:

> import requests cookies = {'status': 'working','color':'blue'}
> response = session.get('https://google.com/', cookies=cookies)
> print(session.cookies.get_dict())

Do you know how to flutter it? I tried something like this but it doesn't seem to have a cookie in the response and the cookie doesn't seem to be sent

  Map<String, String> headers = {
      "status":"working",
      "color":"blue"   
    };
    final BaseOptions dioBaseOptions = BaseOptions(
    baseUrl: 'https://google.com',
    headers: {
      'Cookie': headers,
    },
    );
     dio = Dio(dioBaseOptions);
  var cookieJar=CookieJar();
  dio.interceptors.add(CookieManager(cookieJar));
var response = await dio.get('https://google.com/');

Answer 1

Cookie is set by a server in a response header and a browser sends it back in a request header.

After receiving an HTTP request, a server can send one or more Set-Cookie headers with the response. The browser usually stores the cookie and sends it with requests made to the same server inside a Cookie HTTP header.

See Using HTTP cookies for details.

CookieManager does this for dio and Flutter.

To access Cookies in a dio response

final cookies = response.headers['set-cookie']
