Node.js上的Ajax请求错误

Question

I have a node.js server running on port 3000 and in my index.html file on that server, I send a Ajax request to apache2 server on port 80 to retrieve the current cookie on the site. However, I get no cookie response even though I see the cookie on my browser. My Ajax request on index.html:

$.ajax ({
        type: "GET",
        url: "http://103.57.220.117:80/chatroom/api/auth",
        async: false,
        global: false,
        processData: false,
        contenType: "application/json",
        data: "",
        success: function(r) {
            console.log(r)
        },
        error: function(r) {
            console.log(r)
        }
}); 

In my index.php endpoint on my api file:

if ($_SERVER['REQUEST_METHOD'] == 'GET') {

if ($_GET['url'] == 'auth') {

    $cookie= $_COOKIE['SNID'];
    echo '{ "cookie" : '.$cookie.' }';
    http_response_code(200);

}

}

The api response with the 200 code but no cookie

However, on the browser there is cookie displayed and active (cookie on browser)

Is there any way to fix this? I really need solution because this is very important for my school project

Answer 1

Cookies can not be shared across sites, this includes sites on the same domain but using different ports.
