1. 在utils下新建websocket.js文件
// import { showInfoMsg, showErrorMsg } from '@/utils/popInfo'
import ElementUI from 'element-ui';
function initWebSocket(e) {
console.log(e)
const wsUri = WS_API + "/webSocket/" + e;
this.socket = new WebSocket(wsUri)//这里面的this都指向vue
this.socket.onerror = webSocketOnError;
this.socket.onmessage = webSocketOnMessage;
this.socket.onclose = closeWebsocket;
}
function webSocketOnError(e) {
ElementUI.Notification({
title: '',
message: "WebSocket连接发生错误" + e,
type: 'error',
duration: 0,
});
}
function webSocketOnMessage(e) {
const data = JSON.parse(e.data);
console.log(data.msgType === "INFO", data.msgType === "INFO")
if (data.msgType === "INFO") {
ElementUI.Notification({
title: '',
message: data.msg,
type: 'success',
duration: 3000,
});
} else if (data.msgType === "ERROR") {
ElementUI.Notification({
title: '',
message: data.msg,
type: 'error',
duration: 0,
});
}
}
// 关闭websiocket
function closeWebsocket() {
console.log('连接已关闭...')
}
function close() {
this.socket.close() // 关闭 websocket
this.socket.onclose = function (e) {
console.log(e)//监听关闭事件
console.log('关闭')
}
}
function webSocketSend(agentData) {
this.socket.send(agentData);
}
export default {
initWebSocket, close
}
如果想刷新重新链接websocket 可以在App.vue页面里添加个钩子函数
mounted() {
//当在任一路由页面被刷新时,便是根组件app被从新建立,此时能够进行webSocket重连
//从localStorage中获取用户信息,是登陆状态则能够进行webSocket重连
let token = localStorage.getItem("token");
if (token) {
// userMessage = JSON.parse(userMessage);
this.$websocket.initWebSocket(token);
}
},
客户端主动关闭websocket 在关闭的地方触发函数就可以
logout() {
// localStorage.clear();
localStorage.removeItem("token");
this.$websocket.close();
this.$store.dispatch("LogOut").then(() => {
location.reload();
});
},
注：$webSocket 是在main.js中全局注册了websocket.js文件
