无法使用通道工厂调用匿名WCF服务

本文关键字：WCF 服务 调用 工厂 通道 | 更新日期: 2023-09-27 18:24:34

我正在迁移服务引用以使用通道工厂。

我将服务实现中的接口拆分为一个单独的类库。

  • 类库：IService
  • 类库：Service
  • Web应用程序：参考IService

代码：

配置

<bindings>
      <basicHttpBinding>
        <binding name="basicHttpBindingEndpoint" maxReceivedMessageSize="5242880"/>
      </basicHttpBinding>
    </bindings>

类别：

public class ProxyManager
{
    internal static ConcurrentDictionary<string, ChannelFactory<IService>> proxies = 
                    new ConcurrentDictionary<string, ChannelFactory<IService>>();
    internal static ChannelFactory<IService> CreateChannelFactory()
    {
        Global.Logger.Info("ProxyManager:CreateChannelFactory");
        BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
        EndpointAddress endpointAddress = new EndpointAddress("http://domain/Service.svc");
        var channelFactory = new ChannelFactory<IService>(basicHttpBinding, endpointAddress);
        return channelFactory;
    }
    internal static IService GetProxy(string key)
    {
         Global.Logger.Info("ProxyManager:GetProxy");
         return proxies.GetOrAdd(key, m => CreateChannelFactory()).CreateChannel();
    }
    internal static bool RemoveProxy(string key)
    {
        Global.Logger.Info("ProxyManager:RemoveProxy");
        ChannelFactory<IService> proxy;
        return proxies.TryRemove(key, out proxy);
    }
}

全局：

public static IService ServiceProxy
{
    get
    {
        return ProxyManager.GetProxy("Service");
    }
}

用法：

ServiceProxy.Method();

错误：

例外：

在http://domain/Service.svc上没有侦听到可以接受该消息。这通常是由不正确的地址引起的或SOAP动作。有关更多详细信息，请参见InnerException（如果存在）。

InnerException：远程服务器返回错误：（404）找不到。

  1. "http://domain/Service.svc"上可以访问该服务
  2. 该服务在IIS上启用了"匿名"身份验证，并禁用了"Windows"身份验证

我在这里错过了什么？

故障排除：1.我尝试将绑定设置为"BasicHttpSecurityMode.None"，但没有帮助。2.尝试将Channel Factory窗口凭据设置为"TokenImpersonationLevel.Anonymous"，但没有帮助3.尝试读取endpointaddress的IsAnonymous属性，结果为false

是否可以将通道或通道工厂设置为匿名？是否可以将通道或通道工厂设置为具有命名空间？

详细的错误消息：

无法使用通道工厂调用匿名WCF服务

Service有两个端点——Ajax和Basic。

我没有提到我想在ProxyManager中使用Basic端点。

一旦我更改了下面的代码段，它就起作用了：

internal static ChannelFactory<IService> CreateChannelFactory()
    {
        Global.Logger.Info("ProxyManager:CreateChannelFactory");
        BasicHttpBinding basicHttpBinding = new BasicHttpBinding();
        EndpointAddress endpointAddress = new EndpointAddress("http://domain/Service.svc/Basic");
        var channelFactory = new ChannelFactory<IService>(basicHttpBinding, endpointAddress);
        return channelFactory;
    }

我不清楚错误消息，因为服务地址有效。我应该根据错误消息更正端点地址。
