服务器生成token 设置在响应头，但是前端获取不到

const token = JWT.generate({ id: new Date().getTime(), userName }, '10s')
res.header('Authorization', token)

axios.interceptors.response.use(
    (response) => {
        console.log(response);
        if (response.data?.code == '500') {
            ElMessage.error(response.data.msg)
            router.push('/LoginView')
        } else {
            if (response.config.url == "/lanyaManage/user/login") {
                console.log(response.headers.authorization);
                sessionStorage.setItem('token', response.headers.authorization)
            }
        }

        return response
    },
    (error) => {
        console.log("请求出错：", error);
    }
);

 

 其实这的原因是跨域的问题浏览器无法显示所有的响应头，需要添加设置Access-Control-Expose-Headers即可

 //添加token
const token = JWT.generate({ id: new Date().getTime(), userName }, '10s')
res.header('Authorization', token)
res.setHeader("Access-Control-Expose-Headers", "Authorization")
