express.js 和 react.js cookie 保存到浏览器但不工作？

Question

I have a backend server using express.js I use react for my front end, so when I log in, the cookie will be saved in the browser but for some reason the session is not persisted and when I try to access some information from some route that requires authentication it will deny the access. I use postman to login and it will persist the session with no problem and can access routes that require authentication, so there must be a problem in the front end that it will not be created here's my codes:

Backend:

var cors = require('cors')

app.use(cors({
  origin: 'http://localhost:3000',
  methods: ['POST', 'PUT', 'GET', 'OPTIONS', 'HEAD'],
  credentials: true
}));

Front end:

const postData = () => {  //this is for login
    const requestBody = {
      username: name,
      password: password,
    };
    const config = {
      headers: {
        "Content-Type": "application/x-www-form-urlencoded",
      },
      withCredentials: true,
      accept: "application/json",
    };
    axios
      .post(`${myUrl}/login`, qs.stringify(requestBody), config)
      .then((res) => {
        console.log(res.data);
      })
      .catch((e) => {
        console.log(e);
      });
  };

const getData = async () => { //to access some data that requires authentication
    axios
      .get(`${myUrl}/edit`)
      .then((res) => {
        console.log(res.data);
      })
      .catch((e) => {
        console.log(e);
      });
  };

when I log in with my front end I get a success message that I put (successfully logged in) so that means there is no problem with the post request and the CORS there's only one problem which is the front-end, what might be the problem?

PS: what's so interesting is that the cookie is actually saved in the browser but when I try to access some information that requires authentication it denies access!

Answer 1

try to put the credentials to true in the get request as well:

const getData = async () => { //to access some data that requires authentication
    axios
      .get(`${myUrl}/edit`, { withCredentials: true })
      .then((res) => {
        console.log(res.data);
      })
      .catch((e) => {
        console.log(e);
      });
  };
