Wcf中/部分信任（Mosso） - 奇怪的問題/配置錯誤

Question

噢！好的...我解決了我的Wcf/Linq錯誤（並且學到了很多東西 - 一系列的博客文章將在接下來的較弱版本中發佈）。現在我需要部署。我們運行在Mosso/Rackspace雲環境中，目前環境運行在部分信任環境中。

爲了簡單起見，我在我的Wcf服務中添加了一個方法，它幾乎不做任何事情。

public string Echo(string what) 
{ 
    return what; 
} 

我建這一切，並將它與以下Web.Config運到測試服務器（只有相關的部分）......是的，我需要明顯暴露危險方法之前添加的安全性，但現在我jsut想要匿名的東西運行:)

<system.serviceModel> 
<bindings> 
    <basicHttpBinding> 
     <binding name="BasicAnonymous"> 
      <security mode="None"/>     
     </binding> 
    </basicHttpBinding> 
</bindings> 
<behaviors> 
    <serviceBehaviors> 
    <behavior name="FooBar.Backend.Web.Services.CoreDataWcfServiceBehavior"> 
    <serviceMetadata httpGetEnabled="true" /> 
    <serviceDebug includeExceptionDetailInFaults="true" /> 
    </behavior> 
    </serviceBehaviors> 
</behaviors> 
<services> 
    <service behaviorConfiguration="FooBar.Backend.Web.Services.CoreDataWcfServiceBehavior" 
    name="FooBar.Backend.Web.Services.CoreDataWcfService"> 
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicAnonymous" contract="FooBar.Backend.Web.Services.ICoreDataWcfService" /> 
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
    </service> 
</services> 
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"> 
    <baseAddressPrefixFilters> 
     <add prefix="http://backend.FooBar.com"/> 
    </baseAddressPrefixFilters> 
</serviceHostingEnvironment> 
</system.serviceModel> 

因此，我打電話給我以最簡單的方式，我可以與控制檯應用程序。我添加了服務參考，它增加了罰款。然後我打電話給我（爲了簡潔，我拿了無效代碼）...

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 

using CoreWcfHarness.CoreDataServiceReference; 

namespace CoreWcfHarness 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      var context = new CoreDataWcfServiceClient(); 

      var echoval = context.Echo("Hello World!"); 
      Console.WriteLine(String.Format("{0}\n", echoval)); 
      Console.ReadKey(); 
     } 
    } 
} 

和blammo。我遇到了一個例外。

System.ServiceModel.FaultException`1 was unhandled 
    Message="Request failed." 
    Source="mscorlib"

    InnerException: 

這是因爲它得到一樣簡單。任何熟悉中等信任環境和/或具有堆棧跟蹤的人員？

謝謝！

「請求失敗」可能是一些事情。

看起來最可能的原因是請求沒有到達服務器。您應該檢查服務器日誌以確保將請求發送到正確的位置。
