如何托管公共WCF服务？

Question

我正在尝试创建一个不需要IIS托管且对公众无需身份验证即可访问的TCP WCF服务。

以下是我的步骤：

ServiceHost svh = new ServiceHost(typeof(MyService));

var tcpbinding = new NetTcpBinding(SecurityMode.None);

var location = "net.tcp://localhost:11111";
svh.AddServiceEndpoint(typeof(IMyService), tcpbinding, location);

svh.Open();
....

该服务在本地主机上运行良好，但当我在服务器上设置它（添加了防火墙例外）时，客户端会崩溃并显示以下错误信息：

The socket connection was aborted. This could be caused by an error processing 
your message or a receive timeout being exceeded by the remote host, or an 
underlying network resource issue. Local socket timeout was '00:00:59.7344663'.

以下是客户端配置文件：

这是客户端配置文件：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <netTcpBinding>
                <binding name="NetTcpBinding_IMyService">
                    <security mode="None" />
                </binding>
            </netTcpBinding>
        </bindings>
        <client>
            <endpoint address="net.tcp://myserver:11111/"
                binding="netTcpBinding" bindingConfiguration="NetTcpBinding_IMyService"
                contract="MyServer.IMyService" name="NetTcpBinding_IMyService" />
        </client>
    </system.serviceModel>
</configuration>

我该如何修改才能让这个运作呢？

我曾经遇到过类似的问题，解决方法是在终结点地址（ServiceHost .ctor）中不使用localhost，而是使用实际的机器名称。此外，您还可以在服务主机本身中定义地址，如下所示。

ServiceHost svh = new ServiceHost(typeof(MyService), new Uri("net.tcp://myserver:11111"));
var tcpbinding = new NetTcpBinding(SecurityMode.None);
svh.AddServiceEndpoint(typeof(IMyService), tcpbinding, "");
svh.Open();
