reactjs - 仅当未通过 @azure/msal-react 进行身份验证时才重定向 onLoad

Question

我正在尝试调整 sample project为了我的需要。
我的需求基本上是:

如果用户在导航到根路由时未通过身份验证，则自动重定向登录...

如果是，则加载 protected 子组件。

我有第 1 步。按预期工作。但是，在他们登录后，它似乎正在尝试再次重新路由，我得到:

interaction_in_progress: Interaction is currently in progress. Please ensure that this interaction has been completed before calling an interactive API. For more visit: aka.ms/msaljs/browser-errors

  70 | 
  71 | useEffect(() => {
  72 |   if (!isAuthenticated) {
> 73 |     msalInstance.loginRedirect(loginRequest);
     | ^  74 |   }
  75 | })
  76 | 

无论是否存在 !isAuthenticated，它都会这样做。有条件的。 useIsAuthenticated的用法来自 this documentation并且似乎评估为 false即使用户已经登录。
这是我迄今为止所拥有的:

import { Configuration, RedirectRequest } from '@azure/msal-browser';

// Config object to be passed to Msal on creation
export const msalConfig: Configuration = {
  auth: {
    clientId: '<client_id>',
    authority: 'https://login.microsoftonline.com/<tenant_id>',
  },
};

// Add here scopes for id token to be used at MS Identity Platform endpoints.
export const loginRequest: RedirectRequest = {
  scopes: ['User.Read'],
};

// Add here the endpoints for MS Graph API services you would like to use.
export const graphConfig = {
  graphMeEndpoint: 'https://graph.microsoft.com/v1.0/me',
};

// index.tsx
import React from 'react';
import ReactDOM from 'react-dom';
import App from './components/App';
import { PublicClientApplication } from '@azure/msal-browser';
import { msalConfig } from './components/authConfig';
import { MsalProvider } from '@azure/msal-react';

const msalInstance = new PublicClientApplication(msalConfig);

ReactDOM.render(
  <React.StrictMode>
    <MsalProvider instance={msalInstance}>
      <App />
    </MsalProvider>
  </React.StrictMode>,
  document.getElementById('root')
);

// App.tsx
import React, { useEffect } from 'react';
import {
  AuthenticatedTemplate,
  UnauthenticatedTemplate,
  useMsal,
  useIsAuthenticated,
} from '@azure/msal-react';
import { loginRequest } from './authConfig';

const App = () => {
  const isAuthenticated = useIsAuthenticated();
  const { instance } = useMsal();

  console.log(isAuthenticated);

  useEffect(() => {
    if (!isAuthenticated) {
      instance.loginRedirect(loginRequest);
    }
  });

  return (
    <div className='App'>
      <AuthenticatedTemplate>
        <div>Signed in...</div>
      </AuthenticatedTemplate>

      <UnauthenticatedTemplate>
        <div>Signing in...</div>
      </UnauthenticatedTemplate>
    </div>
  );
};

export default App;

有关如何解决此问题的建议？

好的，我能够在一些帮助下解决这个问题:

const App = () => {
  const isAuthenticated = useIsAuthenticated();
  const { instance, inProgress } = useMsal();

  if (inProgress === InteractionStatus.None && !isAuthenticated) {
    instance.loginRedirect(loginRequest);
  }

  return (
    <div className='App'>
      <AuthenticatedTemplate>
        <div>Signed in...</div>
      </AuthenticatedTemplate>

      <UnauthenticatedTemplate>
        <div>Signing in...</div>
      </UnauthenticatedTemplate>
    </div>
  );
};

export default App;
