使用 get 请求发送 cookie

Question

I 'm authenticating with site https://a.com . Once I authenticate, I access http://b.com . a.com sets a cookie for the session that I need to send with when I make a get request from b.com to a.com.

Can you please tell me, how I can get the cookie and pass it on with my request.

I have tried sending the requests with "withCredentials": true, Also tried using the axios-cookiejar-support with tough-cookie. But doesn't seem to work.

    .get(a.com/path-requiring-cookie, {
      withCredentials: true,
      headers: {
        'Content-Type': 'application/json',
        'access-control-allow-credentials': true,
      },
    })
    .then(res => {
      console.log(res.data);
    });```

This is the code that I have to send the request.

But this doesn't seem to send the cookie with the request.  Can someone please clarify.

Answer 1

Why don't use a javascript function instead that helps use fetch the Cookie based on it's name like below

 function GetCookie(cName) { const name = `${cName}=`; const decodedCookie = decodeURIComponent(document.cookie); const ca = decodedCookie.split(';'); for (let i = 0; i < ca.length; i++) { let c = ca[i]; while (c.charAt(0) === ' ') { c = c.substring(1); } if (c.indexOf(name) === 0) { return c.substring(name.length, c.length); } } return ''; }; console.log(GetCookie("SID"))

Have a look to this question .

The problem you are trying to solve is to read/send cookies from/to different domains.

One solution, as stated in the previously linked question would be to set some headers on http://b.com

Access-Control-Allow-Origin: http://b.com
Access-Control-Allow-Credentials: true

You do that on the server that has the domain http://b.com

Something along those lines should solve the issue for you.
