我的WCF之旅（12）：使用MSMQ进行Reliable Messaging(4)

摘要：在一个分布式的环境中，我们往往需要根据具体的情况采用不同的方式进行数据的传输。比如在一个Intranet内，我们一般通过TCP进行高效的数据通信；而在一个Internet的环境中，我们则通常使用Http进行跨平台的数据交换。

3、Hosting

Configuration

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<netMsmqBinding>
<binding name="msmqBinding">
<security>
<transport msmqAuthenticationMode="None" 
msmqProtectionLevel="None" />
<message clientCredentialType="None" />
</security>
</binding>
</netMsmqBinding>
</bindings>
<services>
<service name="Artech.QueuedService.Service. OrderProcessorService">
<endpoint address="net.msmq://localhost/private/orders" 
binding="netMsmqBinding"
bindingConfiguration="msmqBinding" 
contract="Artech.QueuedService.Contract.IOrderProcessor" />
</service>
</services>
</system.serviceModel>
</configuration>

在默认的情况下，netMsmqBinding 的msmqAuthenticationMode为WindowsDomain，由于基于WindowsDomain必须安装AD，利于在本机模拟，我把msmqAuthenticationMode改为None，相应的ProtectionLevel和clientCredentialType改为None。

Program：

using System;
using System.Collections.Generic;
using System.Text;
using System.Messaging;
using System.ServiceModel;
using Artech.QueuedService.Service;
namespace Artech.QueuedService.Hosting
{
class Program
{
static void Main(string[] args)
{
string path = @".\private$\orders";
if(!MessageQueue.Exists(path))
{
MessageQueue.Create(path,true);
}
using (ServiceHost host = new ServiceHost(typeof(OrderProcessorService)))
{
host.Opened += delegate
{
Console.WriteLine("Service has begun to listen\n\n");
};
host.Open();
Console.Read();
}
}
}
}

在Host Service之前，通过MessageQueue.Create创建一个Message Queue，第二个参数为表明Queue是否支持Transaction的indicator，这里支持Transaction。

4、Client

Configuration

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<netMsmqBinding>
<binding name="msmqBinding">
<security>
<transport msmqAuthenticationMode="None" 
msmqProtectionLevel="None" />
<message clientCredentialType="None" />
</security>
</binding>
</netMsmqBinding>
</bindings>
<client>
<endpoint address="net.msmq://localhost/private/orders" 
binding="netMsmqBinding"
bindingConfiguration="msmqBinding" 
contract="Artech.QueuedService.Contract.IOrderProcessor"
name="defaultEndpoint" />
</client>
</system.serviceModel>
</configuration>
