如何使用reactjs了解用户是否连接到蜂窝网络或wifi

import React from 'react';
import ReactDOM from 'react-dom';

class ConnectionStatus extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      connectionType: ''
    };
  }

  componentDidMount() {
    const connection = navigator.connection || navigator.mozConnection || navigator.webkitConnection;

    if (connection) {
      this.updateConnectionStatus(connection.effectiveType);
      connection.addEventListener('change', () => {
        this.updateConnectionStatus(connection.effectiveType);
      });
    }
  }

  updateConnectionStatus(connectionType) {
    this.setState({ connectionType });
  }

  render() {
    return (
      <div>
        <p>连接类型: {this.state.connectionType}</p>
      </div>
    );
  }
}

ReactDOM.render(<ConnectionStatus />, document.getElementById('root'));
