消费消息
using System;

using System.Threading.Tasks;
namespace ConsoleApp_Consumer
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("消息接收测试");
//测试消费消息
var consumer = new NewLife.RocketMQ.Consumer
{
Topic = "DESKTOP-ACRFQSI",
Group = "CID_ONSAPI_OWNER",
NameServerAddress = "192.168.1.194:9876",
//设置每次接收消息只拉取一条信息
BatchSize = 1,
//FromLastOffset = true,
//SkipOverStoredMsgCount = 0,
//BatchSize = 20,
//Log = NewLife.Log.XTrace.Log,
};
consumer.OnConsume = (q, ms) =>
{
string mInfo= $"BrokerName={q.BrokerName},QueueId={q.QueueId},Length={ms.Length}";
Console.WriteLine(mInfo);
foreach (var item in ms.ToList())
{
string msg = $"消息：msgId={item.MsgId},key={item.Keys}，产生时间【{item.BornTimestamp.ToDateTime()}】，内容>{item.Body.ToStr()}";
Console.WriteLine(msg);
}
// return false;//通知消息队：不消费消息
return true; //通知消息队：消费了消息
};
consumer.Start();
Console.ReadLine();
}
}
}
停止接收RocketMq消息，
consumer.OnConsume = null;
consumer.Dispose();
重新启动接收参考：
static Func<MessageQueue, MessageExt[], bool> reviceMsgFunc= (q, ms) =>
{
// string mInfo = $"BrokerName={q.BrokerName},QueueId={q.QueueId},Length={ms.Length}";
// Console.WriteLine(mInfo);
// LogHelpter.AddLog("********收到消息结构>" + mInfo);
foreach (var item in ms.ToList())
{
string msg = $"消息msgId={item.MsgId},key={item.Keys},QueueOffset={item.QueueOffset}，产生时间【{item.BornTimestamp.ToDateTime()}】，内容>{item.Body.ToStr()}";
Console.WriteLine(msg);
LogHelpter.AddLog("收到消息>" + msg);
}
// return false;//不消费
return true;//消费了消息
};
//启动
Task.Run(() =>
{
System.Threading.Thread.Sleep(50 * 1000);
try
{
consumer = new NewLife.RocketMQ.Consumer
{
Topic = "topic_order_list_print",
Group = "group_order_print",
NameServerAddress = "127.0.0.1:9876",
//设置每次接收消息只拉取一条信息
BatchSize = 1,
//FromLastOffset = true,
//SkipOverStoredMsgCount = 0,
//BatchSize = 20,
//Log = NewLife.Log.XTrace.Log,
};
consumer.OnConsume = reviceMsgFunc;
consumer.Start();
//consumer.StartSchedule();
string log = "再次启动接收消息，成功" + DateTime.Now.ToFullString();
Console.WriteLine(log);
LogHelpter.AddLog(log);
Console.ReadLine();
}
catch (Exception ex)
{
Console.WriteLine("再次启动接收消息出错" + ex.Message);
LogHelpter.AddLog("再次启动接收消息出错," + ex.Message);
}
});
