我有一个 react js 应用程序，它使用 azure 事件目录进行身份验证，然后它显示这个菜单:

但是我希望在登录后，根据从 Azure AD 收到的信息，如 Angular 色或组，然后显示具有不同选项的不同侧边栏，这样我就可以拥有具有不同用户组的相同应用程序，并且菜单将取决于 Angular 色或组。

这是我的应用结构:

相关文件如下:

索引.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();

问题:

如何修改此代码以根据登录用户呈现不同的侧边栏？

最佳答案

第一步高度依赖于您的身份验证配置方式。使用 azure 登录后，您需要将检索到的用户配置文件存储在 redux 数据存储中。

如果您将 react redux 与 adal 一起使用，您应该会发送一个登录操作。 此操作成功后，在您的登录 reducer 中，从检索到的信息中选择您需要的内容。

以下代码只是实现此类 reducer 后可能剩下的示例。 AD 肯定会给你一个组 ID，而不是本例中显示的“管理员” Angular 色，只需相应地修改检查即可。 您可能必须在 AAD 中的应用程序 list 中将 groupMembershipClaims 设置为 "SecurityGroup" 或 "All" 才能添加此部分身份验证响应中的信息。

case Action.LOGIN_SUCCESS:
  return {
    ...state,
    username: action.username,
    isAdmin: action.role === 'admin'
  }

您可能需要自定义 AD 从 AD 仪表板发送给您的信息。

剩下的是微不足道的:

• 将商店连接到需要用户权限的组件

  connect(state => ({
    user: state.loginReducer, 
  }))
  

• 在您的组件内有条件地自定义渲染

  render() {
    const { user } = this.props;
    return (
      <div className={classNames.navbar}>
        { user.isAdmin &&
          <Link to="adminpanel" label="Admin Panel" />
        }
        <Link to="about" label="About" />
      </div>
    )
  }
  

顺便说一句，如果你需要处理动态语言切换，你也应该在 redux 存储中设置语言环境。
