php setcookie没有错误

Question

I'm trying to set cookies with PHP. I wrote a login script that checks data received from the user with database data and then if data matched, it sets a cookie that stores username and password to be used in the next two hours. This is a PHP script to handle an HTTP POST request and output JSON to be used in a react app.

I used ob in my code and I am sure that there are no headers sent before setting cookies.

This is how my code looks like.

    <?php
        ob_start();

        function cook($user, $pass, $time){
            setcookie("user", $user, time() + $time, "/", "localhost", 0);
            setcookie("pass", $pass, time() + $time, "/", "localhost", 0);
        }

        header('Content-Type: application/json');

        //login code(receive data, check password, ...)

        cook($user, hash("sha512", $pass), 7200);

        $output = //my code output object

        echo json_encode($output);

        ob_end_flush();

There is no errors and exception.

UPDATE: I am using cross-origin request. My client is on localhost:3000 and PHP scripts are running on localhost:8080

Problem fixed. The actual problem was from the post request. It did not send the credentials with the request. First, I sat withCredentials to true. Then changed some headers to accept credentials in my apache config like this:

Header set Access-Control-Allow-Origin "http://localdev.localdev.com:3000"
Header set Access-Control-Allow-Headers "Content-Type"
Header set Access-Control-Allow-Credentials "true"

Note: I also added a domain for my 127.0.0.1 in /etc/hosts as I mentioned in comments. I know that is not exactly a PHP problem. But this may help.
