[英]Get WCF client endpoint IP from app.config
I have a client that connects to a WCF service using a netTcpBinding
. 我有一个使用
netTcpBinding
连接到WCF服务的客户端。
To connect to the service I use the following in my client: 要连接到服务,请在客户端中使用以下命令:
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();
}
}
}
For debugging I constantly switch between running the service on my local machine and a remote machine. 为了进行调试,我经常在本地计算机和远程计算机上运行服务之间进行切换。 Is there a way to grab the IP from the client's
app.config
so that I do not have to recompile whenever I want to change the IP? 有没有一种方法可以从客户端的
app.config
获取IP,这样就不必在每次更改IP时都重新编译?
The client app.config
is generated using MEX: 客户端
app.config
使用MEX生成:
<?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>
Ideally, I would just change the IP here. 理想情况下,我只是在这里更改IP。 How can I grab the endpoint address from here?
如何从此处获取端点地址?
Basically, what you could do is create two client-side endpoints - one for each IP you want to connect to, and then pick which one you want in your code. 基本上,您可以做的是创建两个客户端端点-一个您要连接的IP的端点,然后在代码中选择您要的端点。
Your client's app.config
would look something like this: 您客户的
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>
and then in your code, based on some criteria, you would have to use either the tcpLocal
or the tcpRemote
client-side endpoint definition: 然后在代码中,基于某些条件,您将必须使用
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");
Those strings at the end denote the name=
for the <client>/<endpoint>
definition to use in each case. 最后的那些字符串表示在每种情况下使用的
<client>/<endpoint>
定义的name=
。 You can pick the local or the remote connection - or heck, even have both available at the same time, if you like! 您可以选择本地或远程连接-或选择两者,如果愿意,甚至可以同时使用两者! :-)
:-)
将端点名称传递给ChannelFactory构造函数,它将为您从config中查找您的绑定和地址:
ChannelFactory<IMyService> channelFactory = new ChannelFactory<IMyService>("TCPEndPoint");
