使用react-adal为aad身份验证添加错误页

npm install react-adal

import React, { Component } from 'react';

class ErrorPage extends Component {
  constructor(props) {
    super(props);
    this.state = {
      error: null
    };
  }

  componentDidMount() {
    const { error } = this.props;
    this.setState({ error });
  }

  render() {
    const { error } = this.state;
    return (
      <div>
        <h2>身份验证错误</h2>
        <p>{error}</p>
      </div>
    );
  }
}

export default ErrorPage;

import React, { Component } from 'react';
import { AuthenticationContext } from 'react-adal';
import ErrorPage from './ErrorPage';

const config = {
  tenant: 'YOUR_AAD_TENANT',
  clientId: 'YOUR_AAD_CLIENT_ID',
  redirectUri: 'http://localhost:3000',
  cacheLocation: 'localStorage'
};

const authContext = new AuthenticationContext(config);

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      isAuthenticated: false,
      error: null
    };
  }

  componentDidMount() {
    authContext.handleWindowCallback();

    if (authContext.isCallback(window.location.hash)) {
      authContext.handleWindowCallback();
    } else {
      const user = authContext.getCachedUser();
      if (user) {
        this.setState({ isAuthenticated: true });
      } else {
        authContext.login();
      }
    }
  }

  componentDidCatch(error) {
    this.setState({ error: error.toString() });
  }

  render() {
    const { isAuthenticated, error } = this.state;

    if (error) {
      return <ErrorPage error={error} />;
    }

    if (isAuthenticated) {
      return <div>身份验证成功！</div>;
    }

    return <div>正在进行身份验证...</div>;
  }
}

export default App;

import React from 'react';
import ReactDOM from 'react-dom';
import { runWithAdal } from 'react-adal';

runWithAdal(authContext, () => {
  ReactDOM.render(
    <AuthenticationContext.Provider value={authContext}>
      <App />
    </AuthenticationContext.Provider>,
    document.getElementById('root')
  );
});
