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:WorksoftwareApacheZookeeper3confzoo.cfg

以下是kafka的配置

D:WorksoftwareApachekafka2.11configserver.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
