Vue 实现网页聊天功能

基础结构搭建

使用 Vue CLI 或 Vite 创建项目，安装必要依赖：

npm install vue socket.io-client

创建基础组件结构：

<template>
  <div class="chat-container">
    <div class="messages">
      <div v-for="(msg, index) in messages" :key="index">
        {{ msg.user }}: {{ msg.text }}
      </div>
    </div>
    <input v-model="newMessage" @keyup.enter="sendMessage" />
  </div>
</template>

实时通信实现

使用 Socket.IO 建立实时连接：

vue实现网页聊天

import io from 'socket.io-client';

export default {
  data() {
    return {
      socket: null,
      messages: [],
      newMessage: ''
    }
  },
  created() {
    this.socket = io('http://localhost:3000');
    this.socket.on('chat message', (msg) => {
      this.messages.push(msg);
    });
  },
  methods: {
    sendMessage() {
      this.socket.emit('chat message', {
        user: '当前用户',
        text: this.newMessage
      });
      this.newMessage = '';
    }
  }
}

服务端配置

Node.js 服务端示例：

const app = require('express')();
const http = require('http').createServer(app);
const io = require('socket.io')(http);

io.on('connection', (socket) => {
  socket.on('chat message', (msg) => {
    io.emit('chat message', msg);
  });
});

http.listen(3000, () => {
  console.log('listening on *:3000');
});

界面优化

添加样式和交互增强：

vue实现网页聊天

<style scoped>
.chat-container {
  height: 500px;
  display: flex;
  flex-direction: column;
}
.messages {
  flex: 1;
  overflow-y: auto;
  border: 1px solid #eee;
  padding: 10px;
}
input {
  padding: 10px;
  margin-top: 10px;
}
</style>

高级功能扩展

实现用户认证和消息存储：

// 添加用户认证
this.socket = io('http://localhost:3000', {
  auth: {
    token: '用户token'
  }
});

// 消息持久化
socket.on('chat message', async (msg) => {
  await saveMessageToDatabase(msg);
  io.emit('chat message', msg);
});

部署注意事项

配置生产环境：

// 前端适配不同环境
const socket = io(process.env.VUE_APP_SOCKET_URL);

// Nginx 配置 WebSocket 代理
location /socket.io/ {
  proxy_pass http://backend;
  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
}
