Kafka.net使用编程入门(一)

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
     {
         static void Main(string[] args)
         {
             const string topicName = "test";
             var options = new KafkaOptions(new Uri("http://localhost:9092"))
             {
                 Log = new ConsoleLog()
             };

             Task.Run(() =>
             {
                 var consumer = new Consumer(new ConsumerOptions(topicName, new BrokerRouter(options)) { Log = new ConsoleLog() });
                 foreach (var data in consumer.Consume())
                 {
                     Console.WriteLine("Response: PartitionId={0},Offset={1} :Value={2}", data.Meta.PartitionId, data.Meta.Offset, data.Value.ToUtf8String());
                 }
             });

             //创建一个生产者发消息
             var producer = new Producer(new BrokerRouter(options))
             {
                 BatchSize = 100,
                 BatchDelayTime = TimeSpan.FromMilliseconds(2000)
             };

             Console.WriteLine("打出一条消息按 enter...");
             while (true)
             {
                 var message = Console.ReadLine();
                 if (message == "quit") break;

                 if (string.IsNullOrEmpty(message))
                 {
                     //
                     SendRandomBatch(producer, topicName, 200);
                 }
                 else
                 {
                     producer.SendMessageAsync(topicName, new[] { new Message(message) });
                 }
             }

             //释放资源
             using (producer)
             {

             }
         }
         private static async void SendRandomBatch(Producer producer, string topicName, int count)
         {
             //发送多个消息
             var sendTask = producer.SendMessageAsync(topicName, Enumerable.Range(0, count).Select(x => new Message(x.ToString())));

             Console.WriteLine("传送了 #{0} messages.  Buffered:{1} AsyncCount:{2}", count, producer.BufferCount, producer.AsyncCount);

             var response = await sendTask;

             Console.WriteLine("已完成批量发送: {0}. Buffered:{1} AsyncCount:{2}", count, producer.BufferCount, producer.AsyncCount);
             foreach (var result in response.OrderBy(x => x.PartitionId))
             {
                 Console.WriteLine("主题:{0} PartitionId:{1} Offset:{2}", result.Topic, result.PartitionId, result.Offset);
             }

         }
     }

 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
