编写基于WCF服务的程序时,向WCF服务端发送一长串的HTML源码,结果客户端收到提示如下:
格式化程序尝试对消息反序列化时引发异常: 对操作“AddArticle”的请求消息正文进行反序列化时出现错误。读取 XML 数据时,超出最大字符串内容长度配额 (8192)。通过更改在创建 XML 读取器时所使用的 XmlDictionaryReaderQuotas 对象的 MaxStringContentLength 属性,可增加此配额。 第 64 行,位置为 79。
主要是maxStringContentLength和maxReceivedMessageSize的设置会影响到消息的发送和接收,于是全部改为2MB大小,即2097152。
客户端app.config修改:
<bindings> <basicHttpBinding> <binding name="BasicHttpBinding_ShareService" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="2097152" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <!-- Reset maxStringContentLength for deserialize --> <readerQuotas maxDepth="32" maxStringContentLength="2097152" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> </bindings>
服务端web.config修改:
<system.serviceModel> <!-- add for the message size --> <bindings> <basicHttpBinding> <binding name="NewBinding2MB" maxReceivedMessageSize="2097152"> <readerQuotas maxStringContentLength="2097152" /> </binding> </basicHttpBinding> </bindings> <!-- add for the message size --> <behaviors> <serviceBehaviors> <behavior name="Web.WCF.ShareServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="false"/> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> <services> <service behaviorConfiguration="Web.WCF.ShareServiceBehavior" name="Web.WCF.ShareService"> <endpoint address="" binding="basicHttpBinding" bindingConfiguration="NewBinding2MB" contract="Web.WCF.ShareService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> </system.serviceModel>
