Kafka.net使用编程入门

最近研究分布式消息队列，分享下！

首先zookeeper  和 kafka 压缩包 解压 并配置好！

我本机zookeeper环境配置如下:

D:\Worksoftware\ApacheZookeeper3\conf\zoo.cfg

以下是kafka的配置

D:\Worksoftware\Apachekafka2.11\config\server.properties

我已经加了path环境变量，没加的话需要到zookeeper对应bin目录下执行zkServer

然后执行cmd命令:

 

结果:

 然后打开第二个dos窗口,我没加环境变量path,执行kafka命令如下:

 

 

重头戏来了，开始kafka C#客户端处理:

首先引用kafka-net.dll,可以用vs2013的nuget下载，

以下是Prorame.cs

class Program  2  {  3         static void Main(string[] args)  4  {  5             const string topicName = "test";  6             var options = new KafkaOptions(new Uri("http://localhost:9092"))  7  {  8                 Log = new ConsoleLog()  9  }; 10             
            Task.Run(() =>
 { 13                 var consumer = new Consumer(new ConsumerOptions(topicName, new BrokerRouter(options)) { Log = new ConsoleLog() }); 14                 foreach (var data in consumer.Consume()) 15  { 16                     Console.WriteLine("Response: PartitionId={0},Offset={1} :Value={2}", data.Meta.PartitionId, data.Meta.Offset, data.Value.ToUtf8String()); 17  } 18  }); 19 
            //创建一个生产者发消息
            var producer = new Producer(new BrokerRouter(options)) 22  { 23                 BatchSize = 100, 24                 BatchDelayTime = TimeSpan.FromMilliseconds(2000) 25  }; 26 
            Console.WriteLine("打出一条消息按 enter..."); 28             while (true) 29  { 30                 var message = Console.ReadLine(); 31                 if (message == "quit") break; 32 
                if (string.IsNullOrEmpty(message)) 34  { 35                     //
                    SendRandomBatch(producer, topicName, 200); 37  } 38                 else
 { 40                     producer.SendMessageAsync(topicName, new[] { new Message(message) }); 41  } 42  } 43 
            //释放资源
            using (producer) 46  { 47 
 } 49  } 50         private static async void SendRandomBatch(Producer producer, string topicName, int count) 51  { 52             //发送多个消息
            var sendTask = producer.SendMessageAsync(topicName, Enumerable.Range(0, count).Select(x => new Message(x.ToString()))); 54 
            Console.WriteLine("传送了 #{0} messages. Buffered:{1} AsyncCount:{2}", count, producer.BufferCount, producer.AsyncCount); 56 
            var response = await sendTask; 58 
            Console.WriteLine("已完成批量发送: {0}. Buffered:{1} AsyncCount:{2}", count, producer.BufferCount, producer.AsyncCount); 60             foreach (var result in response.OrderBy(x => x.PartitionId)) 61  { 62                 Console.WriteLine("主题:{0} PartitionId:{1} Offset:{2}", result.Topic, result.PartitionId, result.Offset); 63  } 64 
 } 66     }

结果:

闲的蛋疼，随便研究一些好东西，.net环境太封闭，每个.net程序员都要扩展视野，技术交流，本人QQ827937686
