IT技术 - React Axios，无法读取 axios 响应中的 Set-Cookie 标头 - 吾爱随笔录

我无法在 axios 中读取响应对象上的 set-cookie 标头，我将用户/密码发布到后端，并且响应在 Set-Cookie 标头中有授权 cookie，但是我在 res 上看不到它.header 对象，但是如果我使用 chrome 开发工具并打开网络选项卡，我可以在响应标头上看到 cookie。

有什么线索吗？

我的帖子： axios.post( endPointLogin, { email, password }, { withCredentials: true } )

控制台中的 res 对象

带有设置 cookie 标头的 chrome 开发工具上的标头

export function login(email, password) {
  return http.post(
    endPointLogin,
    { email, password },
    { withCredentials: true }
  );
}

    const handleSignIn = async ( e ) => {
        e.preventDefault();
        const respuesta = await login( cuenta.email, cuenta.password );
        console.log( "res:", respuesta );
    };
