c# - WCF 端点让我抓狂

Question

也许我只是不明白，但我有一个部署到 IIS 6 机器上的服务。该机器有一个 LAN 地址和一个公共(public)互联网地址。

我究竟应该如何才能发布这项服务，同时兼具两者的可访问性？

• 地址 1:http://serverName/ServiceName/Service.svc
• 地址 2:http://www.companyName.com/ServiceName/Service.svc

起初我想:没什么大不了的，2个端点。所以我有

<endpoint 
    address="Address 1" 
    binding="wsHttpBinding" 
    bindingConfiguration="DefaultBindingConfiguration" 
    name="RemoteEndpoint" />

<endpoint
    address="Address 2" 
    binding="wsHttpBinding" 
    bindingConfiguration="DefaultBindingConfiguration" 
    name="LocalEndpoint" />

客户端代码如下所示:

public void createServiceProxy()
{
    if (Util.IsOperatingLocally())
        this.proxy = new ProxyClient("LocalEndpoint");
    else
        this.proxy = new ProxyClient("RemoteEndpoint");
}

没有骰子。无法添加服务引用。

No protocol binding matches the given address 'Address 1'. Protocol bindings are configured at the Site level in IIS or WAS configuration.

然后我想:也许主机标签和它的 dns 标签会有帮助。不，那是为了身份验证。

然后我想:我将使用 net.tcp 作为本地端点。糟糕...IIS 6 不支持 net.tcp。

然后我想:我知道，ProxyClient 构造函数将 remoteAddress 字符串作为其第二个参数。现在它看起来像:

<endpoint
    address="" 
    binding="wsHttpBinding" 
    bindingConfiguration="DefaultBindingConfiguration" 
    name="MyEndpointName" />

public void createServiceProxy()
{
    if (Util.IsOperatingLocally())
        this.proxy = new ProxyClient("MyEndpointName", "Address 1");
    else
        this.proxy = new ProxyClient("MyEndpointName", "Address 2");
}

显然不是。尝试实例化 ProxyClient 时...

Could not find endpoint element with name 'MyEndpointName' and contract MyService.IService' in the ServiceModel client configuration section.

这将我引向 app.config，其生成的客户端部分如下所示:

<client>
    <endpoint address="http://localhost:3471/Service.svc" binding="customBinding"
        bindingConfiguration="MyEndpointName" contract="MyService.IService"
        name="MyEndpointName">
        <identity>
            <userPrincipalName value="DevMachine\UserNa,e" />
        </identity>
    </endpoint>
</client>

我觉得这肯定不对。

我的下一个想法是不健康的。请帮忙。

Answer 1

这是我的做法:

PortClient client = new PortClient(); // from the service reference

EndpointAddress endpointAddress;

if (local)
    endpointAddress = new EndpointAddress("http://local/Service.svc");
else
    endpointAddress = new EndpointAddress("http://remote/Service.svc");

client.ChannelFactory.CreateChannel(endpointAddress);
client.RemoteMethod();

等等
