Atitit stomp.js conn连接activemq
目录
1.1. activemq 启动，已经默认开启了stomp ws的接口。。地址是 1
1.3. 注意的问题，，activemq stomp启动的时候，显示端口61613.. 2
url='ws://localhost:61614/stomp';
<Script src="https://cdnjs.cloudflare.com/ajax/libs/stomp.js/2.3.3/stomp.js" ></script>
<script>
// alert()
console.log("-start");
<!--TO 创建socket连接 并订阅相关频道-->
//if port err,so err can show..
url='ws://localhost:61614/stomp';
stompClient = Stomp.client(url);
stompClient.debug= function(str) {
// append the debug log to a #debug div somewhere in the page using JQuery:
console.log("--debg:"+str);
};;
stompClient.heartbeat.outgoing = 20000;
stompClient.connect({}, function (frame) {
// 相当于连接 ws://localhost:8080/gs-guide-websocket/041/hk5tax0r/websocket hk5tax0r就是sessionid
console.log("正在连接");
console.log(frame);
//订阅通用私聊频道 群组也通过这里实现
// must use /topic/xxxName mode tsai nen conn...only xxxName cant uswe..
stompClient.subscribe('/topic/foo.bar', function (greeting) {
console.log("-------------receive..."+greeting);
}
);
//订阅用户上线下线的公共频道
stompClient.subscribe('/topic/userlist', function (greeting) {
});
},function errorCallBack (error) {
// 连接失败时（服务器响应 ERROR 帧）的回调方法
console.log(error);
}
); //end conn
</script>
但事迹ws端口61614.。。再配置文件C:\apache-activemq-5.16.0\conf\activemq.xml里面
指明了词端口

连接mq主题偶可以再admin管理界面看到消费者数量
但是只能使用/topic/xxxx的模式连接主题，，不能直接使用xxx真是麻烦。。。
因为stomp.js的订阅api没有区分队列和订阅，所以要在url里面指定
(Object) subscribe(destination, callback, headers = {})
Note: The library will generate an unique ID if there is none provided in the headers. To use your own ID, pass it using the headers argument
Subscribe to a STOMP Broker location. The return value is an Object with unsubscribe method.
var subscription = client.subscribe("/queue/test", callback);
