Question

我有一个react js应用程序，该应用程序通过azure活动目录进行身份验证，然后显示此菜单：

但是，我希望登录后，根据从Azure AD（例如角色或组）接收到的信息，显示带有不同选项的不同侧边栏，因此我可以将同一个APP与不同用户组一起使用，并且菜单将取决于角色或小组。

这是我的应用程序结构：

问题：

如何根据登录用户修改此代码以呈现不同的侧边栏？

Answer 1

第一步高度依赖于身份验证的配置方式。使用天蓝色登录后，您将希望将检索到的用户配置文件存储在redux数据存储中。

如果您使用带有adal的react redux，则应该分派登录操作。成功执行此操作后，在登录还原器内，从检索到的信息中选择所需的内容。

以下代码只是实现了这样一个化简器后可能剩下的示例。 AD肯定会为您提供一个组ID，而不是此示例中显示的“ admin”角色，只需相应地修改检查即可。 您可能必须在AAD的应用清单中将groupMembershipClaims设置为"SecurityGroup"或"All"，以便将这些信息添加到身份验证响应中。 >

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, 
}))

有条件地在组件内部自定义渲染

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，如果需要处理动态语言切换，还应该在redux存储中设置区域设置。

Answer 2

在提供的代码中，我没有找到一种方法来确定用户是否通过了身份验证。我认为这是重点。

最简单的方法是检查cookie。当然，这取决于身份验证的工作方式。您需要具有一个将检查auth cookie的功能。这样的事情。我正在使用universal-cookie软件包，似乎您的应用是同构的，因此您需要在服务器上传递ssrCookie，您将从res.headers.cookies中获得。如果该应用仅是客户端应用，则可以删除ssrCookie：

 import Cookies from 'universal-cookie'

 const authCookieName = 'awesome_app__token'

 function getCookies(isServer, ssrCookie) {
   if (isServer) {
     return new Cookies(ssrCookie || '')
   } else {
     return new Cookies()
   }
 }

 export function isLoggedIn(isServer, ssrCookie) {
   return !!getToken(getCookies(isServer, ssrCookie), ssrCookie)
 }

 function getToken(isServer, ssrCookie) {
   return getCookies(isServer, ssrCookie).get(authCookieName)
 }

现在，在您的反应代码中，您检查用户是否登录：

import { isLoggedIn } from './thePathToFileWhereThisFunctionsWasSet'

class Sidebar extends Component {
   render() {
     return (
       {isLoggedIn() ? (<div>For logged in user</div>) : (<div>For not logged in users</div>)}
     )
   }
}

Answer 3

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();

这仅在您像以前那样用runWithAdal包裹了主要组件之后。

因此，您可以创建一个新组件SidebarOptions，该组件将决定道具user（user = authContext.getCachedUser();）呈现哪些选项。

另一种选择是为react-adal创建PR，并确保将这些值传递给包装的组件或所有子组件s components (using react-context`）

此外，正如我所看到的，您正在使用redux，因此最好保存用户信息，并使用authContext.getCachedUser()数据在第一个呈现的组件上分派一个动作，然后将其设置在您的商店中，以便于跨应用程式。在withAdalLoginApi的成功回调中可以做到这一点。
