vue+ element Notification消息推送
业务需求:
登录后进入页面,将后端推送过来的【待审批】的消息,用$notify弹出,并且,此推送消息的弹窗可以点击,跳转到审批页面,且展示这条【待审批】的详情弹窗,以供用户审批
首先:登录进入页面后,消息可以显示在任何页面,所以,这个消息推送的【通知】写在了App.vue页面中
然后:既然是消息推送,我们用到的是websocket,实时接收消息
再然后:消息推送的【通知】使用的是element的Notification
再然后~~ 上代码
// App.vue
<template>
<div id="app">
<transition name="fade" mode="out-in">
<router-view/>
</transition>
</div>
</template>
<script>
import Cookie from "js-cookie";
export default {
name: "App",
data() {
return {
socUrl: "localhost:8080"
};
},
created() {
this.initWebSocket();
},
methods: {
initWebSocket() {
this.$http
.service({
method: "get",
url: "/user/current",
data: {
user: Cookie.get("user")
}
})
.then(res => {
const resData = res.data.data;
// ws是一定要写的,this.socUrl :是后端的IP
// "/imserver/" + resData.pkId 是后端给的接口和要传的Id
let socUrl = "ws:" + this.socUrl + "/imserver/" + resData.pkId;
this.webSocket = new WebSocket(socUrl);
this.webSocket.onopen = event => {
console.log("event", event.data);
};
//建立连接成功,就可以推送消息,通知用户了
this.webSocket.onmessage = event => {
if (str != '连接成功') {
const h = this.$createElement;
this.$notify({
title: "审批任务",
message: h("i", { style: "color: teal" }, event.data),
onClick:()=> {
console.log("点击事件");
this.messageGoPath();
}
});
} else {
console.log("无待办审批任务");
}
};
this.webSocket.onclose = event => {
console.log("关闭连接");
};
// this.webSocket.send
if (typeof WebSocket != "function") {
alert("您的浏览器不支持websocket");
}
if (typeof WebSocket != "undefined") {
console.log("您的浏览器支持websocket通信协议");
}
});
},
messageGoPath() {
},
websockonmessage() {
console.log("数据接收");
}
},
};
</script>
<style>
#app {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
background: url("./assets/bg2.png");
background-size: 100% 100%;
/*禁止滚动*/
/*overflow: hidden;*/
}
</style>
因为要在点击的时候根据Id打开这条待审批消息的详情弹窗,并且跳转到这个审批页面
所以~~ 上代码
// App.vue
methods:{
messageGoPath() {
let _this = this;
_this.$router.push({
path: `/demo2/mySp`,
query: {
afterStrId: this.afterStr,
},
});
this.reload(); //在这里加一个刷新,解决弹窗重复显示的问题
console.log("走这里吗", this.$router);
},
}
//审批页面.vue
created() {
// 页面加载时,如果携带了推送消息的id就调用接口 两个id相等,
// 就绑定数据,且显示弹窗
if (this.$route.query.afterStrId ) {
this.$http
.service({
method: "get",
url: "/task/getTaskTableById/" + this.$route.query.afterStrId
})
.then(res => {
if (this.$route.query.afterStrId == res.data.data.id) {
this.addDataSp = res.data.data
this.addRowsSp = true;
}
});
}else{
this.addRowsSp = false;
}
},
