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
{
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
