c# - 如何托管公共(public) WCF 服务？

Question

我正在尝试创建一个 tcp wcf 服务，该服务将托管在没有 IIS 的服务器上，并且公众无需身份验证即可访问。

这是我的做法:

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 locashost 上运行良好，但是当我在服务器上设置它时(添加了防火墙异常(exception))，客户端崩溃并显示一条消息:

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'.

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>

我应该更改什么才能使其正常工作？

我过去遇到过类似的问题，我通过在端点地址(ServiceHost .ctor)中不使用 localhost 而是使用实际的机器名称来解决它.此外，您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();
