今天遇到一个问题,系统基于WCF框架,不同的服务完全相似的代码,一个就报错,一个成功。而且报错的代码其实际顺利运行完毕所有代码,事务也成功地提交了,只是在返回信息时WCF给了一个错误信息:
<Fault xmlns="http://schemas.microsoft.com/ws/2005/05/envelope/none"><Code><Value>Receiver</Value><Subcode><Value xmlns:a="http://schemas.microsoft.com/net/2005/12/windowscommunicationfoundation/dispatcher">a:InternalServiceFault</Value></Subcode></Code><Reason><Text xml:lang="zh-CN">message 对象已被释放。</Text></Reason><Detail><ExceptionDetail xmlns="http://schemas.datacontract.org/2004/07/System.ServiceModel" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><HelpLink i:nil="true"/><InnerException i:nil="true"/><Message>message 对象已被释放。</Message><StackTrace> 在 System.ServiceModel.Channels.ByteStreamMessage.InternalByteStreamMessage.get_Properties() ? 在 System.ServiceModel.OperationContext.get_IncomingMessageProperties() ? 在 System.ServiceModel.Web.IncomingWebRequestContext.get_UriTemplateMatch() ? 在 System.ServiceModel.Description.WebHttpBehavior.TrySetupJavascriptCallback(String callbackParameterName) ? 在 System.ServiceModel.Dispatcher.JavascriptCallbackMessageInspector.BeforeSendReply(Message& reply, Object correlationState) ? 在 System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.BeforeSendReplyCore(MessageRpc& rpc, Exception& exception, Boolean& thereIsAnUnhandledException)</StackTrace><Type>System.ObjectDisposedException</Type></ExceptionDetail></Detail></Fault>
具体web.config配置文件和代码如下:
<?xml version="1.0" encoding="utf-8"?> <configuration> <system.serviceModel> <services> <service behaviorConfiguration="Service.ServiceBehavior" name="VME.Service.PictureService"> <endpoint address="" behaviorConfiguration="VME.Service.ServiceAspNetAjaxBehavior" binding="webHttpBinding" contract="VME.Contract.IPictureService" bindingConfiguration="webBinding" /> </service> <service behaviorConfiguration="Service.ServiceBehavior" name="VME.Service.ServiceService"> <endpoint address="" behaviorConfiguration="VME.Service.ServiceAspNetAjaxBehavior" binding="webHttpBinding" contract="VME.Contract.IServiceService" bindingConfiguration="serviceBinding" /> </service> </services> <behaviors> <endpointBehaviors> <behavior name="VME.Service.ServiceAspNetAjaxBehavior"> <enableWebScript /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="Service.ServiceBehavior"> <serviceThrottling maxConcurrentCalls="50" maxConcurrentSessions="50" maxConcurrentInstances="50"/> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true" /> <dataContractSerializer maxItemsInObjectGraph="2147483647"/> </behavior> </serviceBehaviors> </behaviors> <protocolMapping> <add binding="webHttpBinding" scheme="http" /> </protocolMapping> <bindings> <webHttpBinding> <binding name="webBinding" useDefaultWebProxy="false" crossDomainScriptAccessEnabled="true" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" sendTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:01:00" closeTimeout="00:01:00" transferMode="Streamed" hostNameComparisonMode="StrongWildcard"> <readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647" maxDepth="32" maxBytesPerRead="4096" maxNameTableCharCount="16384"/> <security mode="None"></security> </binding> <binding name="serviceBinding" useDefaultWebProxy="false" crossDomainScriptAccessEnabled="true" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" maxBufferPoolSize="2147483647" sendTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:01:00" closeTimeout="00:01:00" transferMode="Streamed" hostNameComparisonMode="StrongWildcard"> <readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647" maxDepth="32" maxBytesPerRead="4096" maxNameTableCharCount="16384"/> <security mode="None"></security> </binding> </webHttpBinding> </bindings> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel> </configuration>
[ServiceContract] public interface IPictureService { [OperationContract] [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)] bool SendIdCardPicture(Stream idCardImg); } [ServiceContract] public interface IServiceService { [OperationContract] [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)] bool AddService(Stream service); }上面IPictureService接口的程序是能正常返回信息,而IServiceService接口的程序就报错。
有高手请给予指点迷津,到底哪里出了问题。
