公司项目要求要有消息提醒机制 , 多方面考虑用了ActiveMQ ,基本上现在主流的后台语言都没啥问题 , php phthon java nodejs , 等等都没问题 , 各位道友可以去查阅相关资料 , 我这里只粘贴出前端的代码
<template>
<div></div>
</template>
<script>
import Stomp from "stompjs";
function uuid() {
var s = [];
var hexDigits = "0123456789abcdef";
for (var i = 0; i < 36; i++) {
s[i] = hexDigits.substr(Math.floor(Math.random() * 0x10), 1);
}
s[14] = "4"; // bits 12-15 of the time_hi_and_version field to 0010
s[19] = hexDigits.substr((s[19] & 0x3) | 0x8, 1); // bits 6-7 of the clock_seq_hi_and_reserved to 01
s[8] = s[13] = s[18] = s[23] = "-";
var uuid = s.join("");
return uuid;
}
export default {
data() {
return {
// client: Stomp.client("ws://192.168.1.103:61614/stomp")
client: null
};
},
methods: {
onConnected(frame) {
console.log("Connected: " + frame);
var topic = "/topic/charger.messageTopic";
this.client.subscribe(topic, this.responseCallback, this.onFailed);
},
onFailed(frame) {
console.log("Failed: " + frame);
},
responseCallback(frame) {
console.log("得到的消息 msg=>" + frame.body);
console.log(frame)
},
connect() {
this.client= Stomp.client("ws://192.168.1.103:61614/stomp")
var clientid = uuid();
var headers = {
"login": "admin",
"passcode": "admin",
"client-id": clientid,
// additional header
};
this.client.connect(headers, this.onConnected, this.onFailed);
}
},
mounted() {
this.connect()
}
};
</script>
请广大道友注意如果直接install stompjs (中间没点 , 别整错了)那么在vue里面会报错 , 因为还需要install 一下 net
var Stomp = require('./lib/stomp.js');
var StompNode = require('./lib/stomp-node.js');
module.exports = Stomp.Stomp;
module.exports.overTCP = StompNode.overTCP;
module.exports.overWS = StompNode.overWS;
index.js 里面引用到了这个stomp-node.js然儿这个node.js
Stomp = require('./stomp');
net = require('net');
Stomp.Stomp.setInterval = function(interval, f) {
return setInterval(f, interval);
};
用到了net ,
请注意箭头函数的使用 , if你直接使用function的话会有this的指向性问题 , client里面封装了很多原型函数 , 如果this指向调用错误的话这些函数都会找不到
