vue中websocket的使用---详解

<template>
  <div>
    <p>WebSocket状态: {{ wsStatus }}</p>
    <button @click="connectWebSocket">连接WebSocket</button>
    <button @click="sendMessage" :disabled="wsStatus !== 'OPEN'">发送消息</button>
  </div>
</template>
 
<script>
export default {
  data() {
    return {
      ws: null,
      wsStatus: 'CLOSED',
    };
  },
  methods: {
    connectWebSocket() {
      this.ws = new WebSocket('ws://your-websocket-server');
 
      this.ws.onopen = () => {
        this.wsStatus = 'OPEN';
        console.log('WebSocket连接成功');
      };
 
      this.ws.onclose = () => {
        this.wsStatus = 'CLOSED';
        console.log('WebSocket连接已关闭');
      };
 
      this.ws.onerror = error => {
        console.error('WebSocket出错:', error);
      };
 
      this.ws.onmessage = message => {
        console.log('收到消息:', message.data);
      };
    },
    sendMessage() {
      if (this.ws && this.ws.readyState === WebSocket.OPEN) {
        this.ws.send('你的消息内容');
      }
    }
  },
  beforeDestroy() {
    if (this.ws) {
      this.ws.close();
    }
  }
};
</script>

这个代码示例展示了如何在Vue组件中创建和管理WebSocket连接。它包括了连接WebSocket服务器、发送消息、处理打开、关闭和错误事件以及在组件销毁前关闭WebSocket连接的逻辑。
