// 前置代码
const SignIn = () => {
let history = useHistory();
const onSignIn = () => {
window.sessionStorage.setItem("token", token);
history.push("/shop");
}
// 后置代码
}
按照惯例，所有微前端都从
SessionStorage
中获取
token
，并通过它来使用该域的私有
API
。毋庸置疑
，需要经过用户身份认证后才允许显示的每个微前端，都应该验证
token
并
确保用户有权访问内容。在横向拆分的架构中，同一个页面上有多个微前端，微前端容器
需要认证用户，然后为授权用户加载页面的微前端，向未授权用户显示错误提示信息。在
纵向拆分的架构中，在渲染任何组件之前，每个微前端都应该确认
token
有效
，并确认用
户的角色（如果有的话）有权访问相应内容。

目录微前端
目录域可能是所有微前端中最复杂和最大的一个微前端。这是用户访问网站的主需求，它
不仅要易用，还要能够提供用户所寻找的完整信息。

团队负责这个微前端
，其目标是
实现多个视图，以便用户可以通过目录找到可用内容，并查看每个产品的详细信息。将来，
该团队可能需要不断开发新的功能，比如分享买家拍摄的产品图片或添加评论和评分。
该团队将实现所有这些功能并以模块化的方式进行代码开发，以便将来可以轻松地将部分
域移交给另一个团队。强大的封装和稳定的模块化会让 ...
