vue中websoket通信
作者:互联网
1.直接代码实现
// 安装并引入相关模块
import SockJS from 'sockjs-client';
import Stomp from 'stompjs';
export default {
data() {
return {
dataList: []
};
},
mounted:function(){
this.initWebSocket();
},
beforeDestroy: function () {
// 页面离开时断开连接,清除定时器
this.disconnect();
clearInterval(this.timer);
},
methods: {
initWebSocket() {
this.connection();
let self = this;
// 断开重连机制,尝试发送消息,捕获异常发生时重连
this.timer = setInterval(() => {
try {
self.stompClient.send("test");
} catch (err) {
console.log("断线了: " + err);
self.connection();
}
}, 5000);
},
removeTab(targetName) {
console.log(targetName)
},
connection() {
// 建立连接对象
this.socket = new SockJS('http://xxxxxx:8089/ws');//连接服务端提供的通信接口,连接以后才可以订阅广播消息和个人消息
// 获取STOMP子协议的客户端对象
this.stompClient = Stomp.over(this.socket);
// 定义客户端的认证信息,按需求配置
var headers = {
login: 'mylogin',
passcode: 'mypasscode',
// additional header
'client-id': 'my-client-id'
};
// 向服务器发起websocket连接
this.stompClient.connect(headers,(frame) => {
this.stompClient.subscribe('/topic/chat_msg', (msg) => { // 订阅服务端提供的某个topic
consolel.log(msg.body); // msg.body存放的是服务端发送给我们的信息
});
}, (err) => {
// 连接发生错误时的处理函数
console.log(err);
});
},
// 断开连接
disconnect() {
if (this.stompClient != null) {
this.stompClient.disconnect();
console.log("Disconnected");
}
}
}
};
