Vue 实现客服聊天功能

实现客服聊天功能需要结合前端和后端技术。以下是一个基于 Vue.js 的实现方案：

前端实现

安装必要依赖：

npm install vue-socket.io socket.io-client axios

创建聊天组件：

<template>
  <div class="chat-container">
    <div class="messages">
      <div v-for="(msg, index) in messages" :key="index" :class="['message', msg.sender]">
        {{ msg.text }}
      </div>
    </div>
    <div class="input-area">
      <input v-model="newMessage" @keyup.enter="sendMessage" placeholder="输入消息...">
      <button @click="sendMessage">发送</button>
    </div>
  </div>
</template>

<script>
import io from 'socket.io-client';

export default {
  data() {
    return {
      messages: [],
      newMessage: '',
      socket: null
    }
  },
  mounted() {
    this.socket = io('http://your-backend-url');

    this.socket.on('connect', () => {
      console.log('Connected to chat server');
    });

    this.socket.on('message', (message) => {
      this.messages.push(message);
    });
  },
  methods: {
    sendMessage() {
      if (this.newMessage.trim() === '') return;

      const message = {
        text: this.newMessage,
        sender: 'user',
        timestamp: new Date()
      };

      this.socket.emit('message', message);
      this.messages.push(message);
      this.newMessage = '';
    }
  }
}
</script>

<style>
.chat-container {
  max-width: 600px;
  margin: 0 auto;
  border: 1px solid #ddd;
  border-radius: 8px;
  overflow: hidden;
}

.messages {
  height: 400px;
  overflow-y: auto;
  padding: 10px;
  background: #f9f9f9;
}

.message {
  margin: 5px 0;
  padding: 8px 12px;
  border-radius: 18px;
  max-width: 70%;
}

.message.user {
  background: #007bff;
  color: white;
  margin-left: auto;
}

.message.agent {
  background: #e9ecef;
  margin-right: auto;
}

.input-area {
  display: flex;
  padding: 10px;
  background: white;
  border-top: 1px solid #ddd;
}

.input-area input {
  flex-grow: 1;
  padding: 8px;
  border: 1px solid #ddd;
  border-radius: 4px;
}

.input-area button {
  margin-left: 10px;
  padding: 8px 16px;
  background: #007bff;
  color: white;
  border: none;
  border-radius: 4px;
  cursor: pointer;
}
</style>

后端实现（Node.js示例）

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

const app = express();
const server = http.createServer(app);
const io = socketIo(server, {
  cors: {
    origin: "http://your-frontend-url",
    methods: ["GET", "POST"]
  }
});

io.on('connection', (socket) => {
  console.log('New client connected');

  socket.on('message', (message) => {
    // 这里可以添加消息处理逻辑，如保存到数据库
    console.log('Message received:', message);

    // 模拟客服回复
    setTimeout(() => {
      const reply = {
        text: '感谢您的消息，我们会尽快回复您！',
        sender: 'agent',
        timestamp: new Date()
      };
      socket.emit('message', reply);
    }, 1000);
  });

  socket.on('disconnect', () => {
    console.log('Client disconnected');
  });
});

const PORT = process.env.PORT || 3000;
server.listen(PORT, () => {
  console.log(`Server running on port ${PORT}`);
});

数据库集成（可选）

如需持久化聊天记录，可集成MongoDB：

const mongoose = require('mongoose');

// 连接数据库
mongoose.connect('mongodb://localhost:27017/chatdb', {
  useNewUrlParser: true,
  useUnifiedTopology: true
});

// 定义消息模型
const Message = mongoose.model('Message', {
  text: String,
  sender: String,
  timestamp: Date
});

// 在socket.io消息处理中保存消息
socket.on('message', async (message) => {
  const msg = new Message(message);
  await msg.save();

  // 广播消息
  io.emit('message', message);
});

高级功能扩展

实现用户认证：

// 前端添加认证头
this.socket = io('http://your-backend-url', {
  auth: {
    token: localStorage.getItem('authToken')
  }
});

// 后端验证
io.use((socket, next) => {
  const token = socket.handshake.auth.token;
  if (verifyToken(token)) {
    next();
  } else {
    next(new Error('Authentication error'));
  }
});

添加消息已读状态：

// 消息模型添加read字段
const Message = mongoose.model('Message', {
  text: String,
  sender: String,
  timestamp: Date,
  read: Boolean
});

// 标记消息为已读
socket.on('markAsRead', async (messageId) => {
  await Message.findByIdAndUpdate(messageId, { read: true });
});
