在我们用WCF传输数据的时候,如果启用默认配置,传输的数据量过大,经常会出这个错误。
WCF包含服务端与客户端,所以这个错误可能出现在服务端返回数据给客户端,或客户端传数据给服务端时。
1. 服务端返回数据给客户端报错
在客户端配置文件中,主要是配置maxReceivedMessageSize
<system.serviceModel> <bindings> <basicHttpBinding> <binding name="ServiceProxyBinding" closeTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <readerQuotas maxStringContentLength="134217728" /> </binding> </basicHttpBinding> </bindings> <client> <endpoint address="http://localhost:5239/AHMTService/PartService.svc" binding="basicHttpBinding" bindingConfiguration="ServiceProxyBinding" contract="UniCloud.ServiceContracts.IPartService" name="IPartService" /> </client> </system.serviceModel>
2 客户端传数据给服务端报错
修改服务端web.config,主要也是配置maxReceivedMessageSize
<system.serviceModel> <services> <!--DecodeService 服务端配置 增加接收文件大小--> <service name="UniCloud.Services.DecodeService" behaviorConfiguration="MyServiceBehaviour" > <endpoint address="" binding="basicHttpBinding" bindingConfiguration="MyServiceBinding" contract="UniCloud.ServiceContracts.IDecodeService"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> <host> <baseAddresses> <add baseAddress="http://localhost:5239/AHMTService"/> </baseAddresses> </host> </service> </services> <bindings> <basicHttpBinding> <binding name="MyServiceBinding" closeTimeout="00:10:00" receiveTimeout="00:20:00" sendTimeout="00:20:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <security mode="None"></security> </binding> </basicHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="MyServiceBehaviour"> <!-- 为避免泄漏元数据信息,请在部署前将以下值设置为 false --> <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> <!-- 要接收故障异常详细信息以进行调试,请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 --> <serviceDebug includeExceptionDetailInFaults="true" /> <dataContractSerializer maxItemsInObjectGraph="2147483647"/> </behavior> </serviceBehaviors> </behaviors> <protocolMapping> <add binding="basicHttpsBinding" scheme="https" /> </protocolMapping> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel>
其实要修改所有的服务,不管是服务端还是客户端,Binding那边增加一个没有设置名字的默认配置就OK了
<binding closeTimeout="00:10:00" receiveTimeout="00:20:00" sendTimeout="00:20:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
