我用以下问题试了3天。请帮我解决这个问题,
>Error: Unexpected close

我正在使用amqplib + node js。每当我启动服务器时,我都会在一段时间内得到上述错误。最大值将以5分钟的间隔发生。
amqplib = amqplib.connect('amqp://'+rabit_host).then(function(conn)
{
amqpconnection = conn;
});
io.sockets.on('connection', function(client)
{
client.on('receivemsg', function(arg)
{
amqpconnection.createConfirmChannel().then(function(channelObjSuccess)
{
channelObjSuccess.assertQueue(queue_name,{durable:false,autoDelete:true});
client.assignObj = channelObjSuccess;
channelObjSuccess.consume(queue_name, function(msg)
{
var encodemsg = msg.content.toString();
var json_msg = JSON.parse(encodemsg);
client.emit('chatrecive',json_msg);
}).then(function(){
console.log("Receive Consiuume Close");
});
});
});
client.on('loginentry', function(arg)
{
amqpconnection.createConfirmChannel().then(function(channelObjSuccess) {
channelObjSuccess.assertQueue(queue_name,{durable:false,autoDelete:true});
});
});
client.on('sendmsg', function(arg)
{
var payload_stringify = JSON.stringify(arg);
amqpconnection.createConfirmChannel().then(function(channelObjSuccess) {
channelObjSuccess.assertQueue(queue_name,{durable:false,autoDelete:true});
channelObjSuccess.sendToQueue(queue_name, new Buffer(payload_stringify), {},
function(err, ok)
{
if (err !== null)
console.log('Message Send Failure! ');
else
{
channelObjSuccess.close();
}
});
});
});
client.on('disconnect', function()
{
try {
console.log("AMPQ Connection Closed - Disconnect");
if(typeof(client.assignObj)!=undefined)
{
client.assignObj.close();
}
}
catch (alreadyClosed) {
console.log("RabbitMQ Connection Already Closed " + alreadyClosed.stackAtStateChange);
}
});
});
server.listen(port);
答案 0 :(得分:2)
我想我找到了答案,可能是连接到AMQP时心跳作为选项的问题。 例如:
url = "amqp://turtle.rmq.cloudamqp.com/bqftjxzn?heartbeat=45";
