如何为RabbitMQ启用服务器端心跳？

Question

我在PhoneGap上使用web-stomp插件+ SockJS/Stomp.js并观察到在某些情况下(可能与网络有关),流量可以在不触发连接错误的情况下停止.为了解决这个问题,我认为我可能会使用心跳,所以我在js中添加了以下内容:

function Connect() {
    console.log('Connecting...');
    // Connect
    var ws = new SockJS(mq_url);
    client = Stomp.over(ws);
    client.heartbeat.outgoing = 5000;   // if 5000 means client will send heart beat every 5000ms
    client.heartbeat.incoming = 5000;   // if 0 means client does not want to receive heartbeats from server
    client.debug = function (str) {
        $("#debug").append(timeStamp() + str + "<br>");  
        varmessage = str;
    };
    client.connect(
    mq_username, mq_password, on_connect, on_connect_error, mq_vhost);
}

但是,服务器不发送心跳,因此抛出以下错误:

-> PING
-> PING
did not receive server activity for the last 10017ms
Whoops!  Lost connection to undefined

我尝试将心跳param添加到rabbitmq.config,但这似乎不起作用.doc没有提到heartbeat参数是用于客户端还是服务器心跳.

[
       {rabbit, [
                {cluster_nodes, {['rabbit@server'], disc}},
                 {cluster_partition_handling, autoheal},
         {heartbeat, 1}
        ]},

心跳参数在客户端实现。RabbitMQ会响应客户端发出的心跳。服务器可以要求客户端按照一定的时间间隔发送心跳，但客户端不必遵循。AMQP 参考；RabbitMQ 参考
