从app.config中获取WCF客户端端点IP
本文关键字:客户端 端点 IP WCF 获取 app config | 更新日期: 2023-09-27 18:10:46
我有一个使用netTcpBinding
连接到WCF服务的客户端。
要连接到服务,我在客户端使用以下命令:
namespace Embedded_DCC_Client
{
public class EmbeddedClient
{
private ChannelFactory<IEmbeddedService> channelFactory;
//Embedded DCC TCP Addresses
public const String LOCAL_ADDRESS = "net.tcp://localhost:9292/EmbeddedService";
public const String REMOTE_ADDRESS = "net.tcp://192.168.10.42:9292/EmbeddedService";
public IEmbeddedService Proxy { get; private set; }
public EmbeddedClient()
{
//Configure binding
NetTcpBinding binding = new NetTcpBinding();
binding.OpenTimeout = TimeSpan.MaxValue; //infinite open timeout
binding.CloseTimeout = TimeSpan.MaxValue; //infinite close timeout
binding.SendTimeout = TimeSpan.MaxValue; //infinite send timeout
binding.ReceiveTimeout = TimeSpan.MaxValue; //infinite recieve timeout
binding.Security.Mode = SecurityMode.None; //No security mode
//Setup the channel to the service...
//TODO debugging use a proper IP address here, and read it from a file. Allows devs to switch between simulator (localhost) and actual embedded DCC
channelFactory = new ChannelFactory<IEmbeddedService>(binding, new EndpointAddress(REMOTE_ADDRESS));
}
public void Open()
{
Proxy = channelFactory.CreateChannel();
}
public void Close()
{
channelFactory.Close();
}
}
}
为了调试,我经常在本地机器和远程机器上运行服务之间切换。是否有一种方法可以从客户端的app.config
中获取IP,以便我不必在想要更改IP时重新编译?
客户端app.config
是使用MEX生成的:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<netTcpBinding>
<binding name="TCPEndPoint" closeTimeout="00:01:00" openTimeout="00:01:00"
receiveTimeout="00:10:00" sendTimeout="00:01:00" transactionFlow="false"
transferMode="Buffered" transactionProtocol="OleTransactions"
hostNameComparisonMode="StrongWildcard" listenBacklog="10"
maxBufferPoolSize="524288" maxBufferSize="65536" maxConnections="10"
maxReceivedMessageSize="65536">
<readerQuotas maxDepth="32" maxStringContentLength="8192"
maxArrayLength="16384" maxBytesPerRead="4096"
maxNameTableCharCount="16384" />
<reliableSession ordered="true" inactivityTimeout="00:10:00"
enabled="false" />
<security mode="None">
<transport clientCredentialType="Windows"
protectionLevel="EncryptAndSign">
<extendedProtectionPolicy policyEnforcement="Never" />
</transport>
<message clientCredentialType="Windows" />
</security>
</binding>
</netTcpBinding>
</bindings>
<client>
<endpoint name="TCPEndPoint"
address="net.tcp://localhost:9292/EmbeddedService"
binding="netTcpBinding"
bindingConfiguration="TCPEndPoint"
contract="ServiceReference1.IEmbeddedService" />
</client>
</system.serviceModel>
</configuration>
理想情况下,我只会改变这里的IP。我如何从这里获取端点地址?
基本上,您可以做的是创建两个客户端端点-一个用于您想要连接的IP,然后在代码中选择您想要的一个。
您的客户端的app.config
看起来像这样:
<client>
<endpoint name="tcpLocal"
address="net.tcp://localhost:9292/EmbeddedService"
binding="netTcpBinding"
bindingConfiguration="TCPEndPoint"
contract="ServiceReference1.IEmbeddedService" />
<endpoint name="tcpRemote"
address="net.tcp://192.168.10.42:9292/EmbeddedService"
binding="netTcpBinding"
bindingConfiguration="TCPEndPoint"
contract="ServiceReference1.IEmbeddedService" />
</client>
,然后在您的代码中,基于某些标准,您将不得不使用tcpLocal
或tcpRemote
客户端端点定义:
// connect to the local address
channelFactoryLocal = new ChannelFactory<IEmbeddedService>("tcpLocal");
// or connect to the remote address
channelFactoryRemote = new ChannelFactory<IEmbeddedService>("tcpRemote");
末尾的字符串表示<client>/<endpoint>
定义在每种情况下使用的name=
。您可以选择本地或远程连接——如果您愿意,甚至可以同时使用这两种连接!: -)
将端点名称传递给ChannelFactory构造函数,它将从配置中为您查找绑定和地址:
ChannelFactory<IMyService> channelFactory = new ChannelFactory<IMyService>("TCPEndPoint");
