在react中使用socket.on的正确方法

npm install socket.io-client

import React, { Component } from 'react';
import io from 'socket.io-client';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.socket = io('http://your-socket-server-url');
  }

  // 其他组件代码...

}

import React, { Component } from 'react';
import io from 'socket.io-client';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.socket = io('http://your-socket-server-url');
  }

  componentDidMount() {
    this.socket.on('event-name', (data) => {
      // 处理接收到的数据
      console.log(data);
    });
  }

  // 其他组件代码...

}

import React, { Component } from 'react';
import io from 'socket.io-client';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.socket = io('http://your-socket-server-url');
  }

  componentDidMount() {
    this.socket.on('event-name', (data) => {
      // 处理接收到的数据
      console.log(data);
    });
  }

  componentWillUnmount() {
    this.socket.off('event-name');
  }

  // 其他组件代码...
