加了心跳检测，还是不停的重连

function cateWebSocket(){
    try {
        ws = new WebSocket(wsUrl);
        initWebSocket();
    } catch (e) {
        reconnect();
    }
}

function initWebSocket(){
var msgloc=-1;
console.log("服务状态：连接中");
ws.onopen=function(){
var login_data = {type:"login",roomId:{sp$shopId},name:"管理员",userface:"",role:"member"};
ws.send(JSON.stringify(login_data));
 
heartCheck.reset().start();
};
ws.onmessage=function(e){
console.log(e.data);
var ret = JSON.parse(e.data);
switch(ret){
case "ping":
 
break;
case "chat":
console.log(ret);
break;
}
 
heartCheck.reset().start();
};
ws.onclose = function(e) {
reconnect(wsUrl);
};
ws.onerror = function() {
reconnect(wsUrl);
};
}
 
function reconnect() {
if(lockReconnect) return;
lockReconnect = true;
//没连接上会一直重连，设置延迟避免请求过多
setTimeout(function () {
cateWebSocket();
lockReconnect = false;
}, 2000);
}
 
//心跳检测
var heartCheck = {
timeout: 20000,//60秒
timeoutObj: null,
serverTimeoutObj: null,
reset: function(){
clearTimeout(this.timeoutObj);
clearTimeout(this.serverTimeoutObj);
return this;
},
start: function(){
var self = this;
this.timeoutObj = setTimeout(function(){
//这里发送一个心跳，后端收到后，返回一个心跳消息，
//onmessage拿到返回的心跳就说明连接正常
if(ws.readyState===1){
var data={type:"pong"};
ws.send(JSON.stringify(data));
}
self.serverTimeoutObj = setTimeout(function(){//如果超过一定时间还没重置，说明后端主动断开了
ws.close();//如果onclose会执行reconnect，我们执行ws.close()就行了.如果直接执行reconnect 会触发onclose导致重连两次
}, self.timeout);
}, this.timeout);
}
}
