Asp.net WCF响应太长-身份验证错误
在我目前工作的项目中,公开了一个WCF服务,它返回一个业务实体数组,我们称之为Invoice:Asp.net WCF响应太长-身份验证错误,asp.net,wcf,windows-authentication,communicationexception,Asp.net,Wcf,Windows Authentication,Communicationexception,在我目前工作的项目中,公开了一个WCF服务,它返回一个业务实体数组,我们称之为Invoice: Invoice[] GetInvoicesByTypeAndTime(InvoiceType invoiceType, byte startHour, byte? endHour); 使用的身份验证机制是Windows身份验证,WCF服务托管在IIS 6上托管的Web应用程序中 起初,当我获取超过64kB的数据时,抛出了一个CommunicationException,指出“已超过传入消息的最大消息
Invoice[] GetInvoicesByTypeAndTime(InvoiceType invoiceType, byte startHour, byte? endHour);
使用的身份验证机制是Windows身份验证,WCF服务托管在IIS 6上托管的Web应用程序中
起初,当我获取超过64kB的数据时,抛出了一个CommunicationException,指出“已超过传入消息的最大消息大小配额(65536)。若要增加配额,请在相应的绑定元素上使用MaxReceivedMessageSize属性。”
很好,我只是在App.config中将maxReceivedMessageSize和maxBufferSize的值增加到65536000(我在末尾公然添加了三个零)(后者是因为它在ArgumentException中抱怨“对于TransferMode.Buffered,maxReceivedMessageSize和maxBufferSize必须是相同的值。
参数名称:bindingElement“)
现在我可以收到更多的回复
直到我达到另一个极限(我想),在624个元素(大约2.2MB)之后,会抛出一个奇怪的异常:
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.

对经过身份验证的响应有限制吗?ASP.NET设置是否有限制?在客户端查看一下,如果您想要TLDR版本-要查看这是否确实是您的问题,您可以设置最大值(Int32.MaxValue),如下所示
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
我猜您使用的是Windows身份验证,因此是401,而不是一条解释您如何突破消息限制的消息。当您通过Windows身份验证请求发送时,WCF会发送SOAP请求两次,一次失败并返回accepts标头,第二次与Windows身份验证标头一起发送 然而,从我的测试来看,如果消息真的通过了,那么它实际上会失败,那么您仍然会得到401 要解决此问题,我必须将服务器跟踪日志设置为:
<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>
然后,我必须输入更大的读者配额,如上所述(但我使用了更小的值):
然后,通常必须加入自定义行为以增加对象图中的最大项数:
<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>
您需要向“
”元素添加一个值为“MaximumItemsBehaviour”的“行为配置”属性
我读过的其他建议,但我并不需要自己补充:
<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpRuntime maxRequestLength="2097151" />
</system.web>
