WCF響應 - 驗證錯誤

Question

在我目前是有暴露它返回一個商業實體的陣列WCF服務工作的項目，讓我們把它發票：

Invoice[] GetInvoicesByTypeAndTime(InvoiceType invoiceType, byte startHour, byte? endHour); 

的身份驗證機制使用是Windows身份驗證，WCF服務託管在託管在IIS 6上的Web應用程序中。

首先，當我用於獲取超過64kB的數據時，拋出CommunicationException，指出「傳入消息的最大消息大小配額（65536 ）已超出。要增加配額，請使用適當的MaxReceivedMessageSize屬性綁定元素「。很好，我只是在App.config中將值增加到65536000（我最後在最後添加了三個零），這兩個值都是maxReceivedMessageSize和maxBufferSize（後者是因爲它在ArgumentException中抱怨「對於TransferMode.Buffered，MaxReceivedMessageSize和MaxBufferSize必須是相同的值。 參數名稱：bindingElement「）。

現在我能得到更大的反應......

直到我打了另一個極限（我認爲）後624元一個奇怪的異常被拋出（約2.2 MB）：

System.ServiceModel.Security.MessageSecurityException: The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'. ---> System.Net.WebException: The remote server returned an error: (401) Unauthorized. 
    at System.Net.HttpWebRequest.GetResponse() 
    at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout) 
    --- End of inner exception stack trace --- 

服務器堆棧跟蹤：

異常重新拋出

驗證響應是否有限制？ ASP.NET設置有沒有限制？

Answer 1

我猜你正在使用Windows身份驗證，因此是401而不是解釋你如何吹掉消息限制的消息。當您通過Windows Authenticated請求發送時，WCF會發送兩次SOAP請求，一次發送失敗並返回接受標頭，第二次用Windows Authentication標頭髮送它。

但是，從我的測試看來，如果郵件確實通過了，它仍然會失敗。

要解決這個問題，我不得不把服務器跟蹤日誌記錄中：

<system.diagnostics> 
    <trace autoflush="true" /> 
    <sources> 
     <source name="System.ServiceModel" switchValue="Critical, Error, Warning"> 
     <listeners> 
      <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData="C:\Logs\ServiceTrace.svclog"/> 
     </listeners> 
     </source> 
    </sources> 
    </system.diagnostics> 

然後，我不得不把在較大的讀者配額，如上述（但我用更小的值）：

那你一般都放在一個自定義的行爲，以增加對象圖的最大項目數：

<behaviors> 
    <serviceBehaviors> 
    <behavior name="MaximumItemsBehaviour"> 
     <dataContractSerializer maxItemsInObjectGraph="2147483647" /> 
     <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> 
     <serviceMetadata httpsGetEnabled="true" httpGetEnabled="false" /> 
     <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> 
     <serviceDebug includeExceptionDetailInFaults="true" /> 
    </behavior> 
    </serviceBehaviors> 
</behaviors> 

您需要爲值爲「MaximumItemsBehaviour」的「<system.serviceModel><services><service>」元素添加「behaviourConfiguration」屬性。

其他建議我讀，但也沒必要自己是添加：

<system.web> 
    <compilation debug="true" targetFramework="4.0" /> 
    <httpRuntime maxRequestLength="2097151" /> 
    </system.web> 

和：

<system.webServer> 
    <modules runAllManagedModulesForAllRequests="true" /> 
    <security> 
     <requestFiltering> 
     <requestLimits maxAllowedContentLength="209715200"/> 
     </requestFiltering> 
    </security> 
    </system.webServer>

在客戶端看看readerQuotas，如果你想要TLDR版本 - 看看這是否確實是你的問題，你可以設置最大值（Int32.MaxValue），如下所示。

<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
