// node expressres.redirect(302, 'http://myweb.com/app/');我的登錄和/app是兩套angular應用，我想實現在登錄成功之后，后端302重定向到/app頁面，但是沒成功。報錯：A wildcard '*' cannot be used in the 'Access-Control-Allow-Origin' header when the credentials flag is true. Origin 'null' is therefore not allowed access. The credentials mode of an XMLHttpRequest is controlled by the withCredentials attribute.求助，如何解決呢？
