無法使用Channel Factory調用匿名WCF服務

Question

我正在遷移服務參考以使用渠道工廠。

我將接口從服務實現中拆分為一個單獨的類庫。

• 類庫： IService
• 類庫： Service
• Web應用程序：對IService引用

碼：

設定檔

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

類：

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);
    }
}

全球：

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

用法：

ServiceProxy.Method();

錯誤：

例外：

在http://domain/Service.svc上沒有偵聽終結點的端點可以接受該消息。 這通常是由不正確的地址或SOAP操作引起的。 有關更多詳細信息，請參見InnerException（如果存在）。

InnerException：遠程服務器返回錯誤：（404）找不到。

1. 該服務可以在"http://domain/Service.svc"
2. 該服務在IIS上啟用了“匿名”身份驗證，並禁用了“ Windows”身份驗證

我在這里想念什么？

故障排除： 1.我嘗試將綁定設置為沒有幫助的“ BasicHttpSecurityMode.None”。 2.嘗試將Channel Factory Windows憑據設置為“ TokenImpersonationLevel.Anonymous”，這無濟於事。3.嘗試讀取Endpointaddress的IsAnonymous屬性，並且它為false

可以將渠道或渠道工廠設置為匿名嗎？ 是否可以將通道或通道工廠設置為具有名稱空間？

Answer 1

服務有兩個端點-Ajax和Basic。

我沒有提到我想在ProxyManager中使用Basic端點。

一旦我更改了下面的代碼段，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;
    }

該錯誤消息對我來說並不清晰，因為服務地址有效。 我應該已經根據錯誤消息更正了端點地址。
