我遇到一个问题,我有一个作为预定任务运行的控制台应用程序,它向Rabbit队列发送了约35万条消息,处理了队列并结束了。我的问题是,在消息实际上完全发布之前,model.BasicPublish返回,并且在调用model.Close时,它最终超时了。我注意到的另一件事是,在应用程序结束并关闭后,Rabbit Management UI表示交换仍在接收消息约30-45秒。我正在使用5.1.0的RabbitMQ.Client块软件包
代码非常简单,并且可以复制/粘贴(用户名/密码除外)
var connectionFactory = new ConnectionFactory();
connectionFactory.HostName = "localhost";
connectionFactory.Password = "pass";
connectionFactory.UserName = "user";
connectionFactory.VirtualHost = "test";
var connection = connectionFactory.CreateConnection();
var model = connection.CreateModel();
model.QueuePurge("x");
var fileLines = File.ReadAllLines(@"bigfile.txt");
var accounts = fileLines.Select(x => x.Split(',').FirstOrDefault()).Where(x => !string.IsNullOrWhiteSpace(x));
var watch = new Stopwatch();
watch.Start();
Console.WriteLine("Start: " + DateTime.Now);
foreach (var account in accounts)
{
var bytes = Encoding.Default.GetBytes(account);
model.BasicPublish("incoming", "", null, bytes);
}
Console.WriteLine("Done: " + DateTime.Now);
Console.WriteLine("Time: " + watch.Elapsed);
try
{
model.Close();
}
catch (Exception exception)
{
Console.WriteLine("Error: " + exception);
}
我的兔子配置用于队列和交换:
{
"rabbit_version": "3.7.7",
"policies": [],
"queues": [
{
"name": "x",
"durable": false,
"auto_delete": false,
"arguments": {}
}
],
"exchanges": [
{
"name": "incoming",
"type": "direct",
"durable": false,
"auto_delete": false,
"internal": false,
"arguments": {}
}
],
"bindings": [
{
"source": "incoming",
"destination": "x",
"destination_type": "queue",
"routing_key": "",
"arguments": {}
}
]
}
foreach块大约需要14秒钟。
有人对如何使其正常工作有任何想法吗?预先感谢。

Rabbit Management UI表示交易所仍在接收消息 持续约30-45秒
那是由于网络数据缓冲。
我的问题是model.BasicPublish在返回之前 消息实际上已完全发布,并且在model.Close为 叫做结束超时
在这种情况下,您应该启用发布者确认(通过ConfirmSelect
和WaitForConfirms
),并且只有在确认所有发布的消息之后才关闭模型。
