如何根据用户信息显示不同的侧边栏？登录后.ReactJS

Question

我有一个react js应用程序,它使用azure活动目录进行身份验证,然后显示以下菜单:

但是我希望在登录后,根据从Azure AD Like Roles Or groups收到的信息,然后显示具有不同选项的不同侧栏,因此我可以使用不同用户组的相同APP,菜单将取决于角色或团体.

这是我的app结构:

以下是相关文件:

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import DashApp from './dashApp';
import registerServiceWorker from './registerServiceWorker';
import 'antd/dist/antd.css';
import { runWithAdal } from 'react-adal';
import { authContext } from './adalConfig';

const DO_NOT_LOGIN = false;
runWithAdal(authContext, () => {
  ReactDOM.render(<DashApp />, document.getElementById('root'));
  // Hot Module Replacement API
  if (module.hot) {
    module.hot.accept('./dashApp.js', () => {
      const NextApp = require('./dashApp').default;
      ReactDOM.render(<NextApp />, document.getElementById('root'));
    });
  }

},DO_NOT_LOGIN);

registerServiceWorker();

题:

如何根据登录用户修改此代码以呈现不同的侧边栏？

Answer 1

在深入研究react-adal代码后，我发现logged状态没有通过子级上下文传递。据我所知，获取当前用户的唯一方法是：

import { authContext } from './adalConfig';
authContext.getCachedUser();

只有在您像之前那样包装了主要组件之后才会这样做runWithAdal。

这样您就可以创建一个新组件SidebarOptions，它将决定要渲染的 prop user( user = authContext.getCachedUser();) 选项。

另一种选择是创建 PRreact-adal并确保通过包装组件或所有子组件传递这些值` s components (using)

另外，正如我所看到的，您正在使用 redux，因此最好通过在带有数据的第一个渲染组件上分派操作来保存用户信息authContext.getCachedUser()，并将其设置在您的商店中，以便在应用程序中轻松访问。执行此操作的一个好地方是在 的成功回调中withAdalLoginApi。
