WCF字符串過(guò)長(zhǎng)問(wèn)題解決方法指南
作者：佚名
WCF字符串過(guò)長(zhǎng)問(wèn)題在實(shí)際使用中比較常見(jiàn)。不過(guò)這種問(wèn)題的解決方法也是比較簡(jiǎn)單的，在這里就為大家詳細(xì)介紹相關(guān)解決方案。
WCF框架是一個(gè)比較常用的開(kāi)發(fā)框架，可以幫助開(kāi)發(fā)人員實(shí)現(xiàn)許多功能，提供了相當(dāng)大的幫助。編寫(xiě)基于WCF服務(wù)的程序時(shí)，向WCF服務(wù)端發(fā)送一長(zhǎng)串的HTML源碼，結(jié)果客戶(hù)端收到提示如下：#t#
格式化程序嘗試對(duì)消息反序列化時(shí)引發(fā)異常: 對(duì)操作“AddArticle”的請(qǐng)求消息正文進(jìn)行反序列化時(shí)出現(xiàn)錯(cuò)誤。讀取 XML 數(shù)據(jù)時(shí)，超出***字符串內(nèi)容長(zhǎng)度配額 (8192)。通過(guò)更改在創(chuàng)建 XML 讀取器時(shí)所使用的 XmlDictionaryReaderQuotas 對(duì)象的 MaxStringContentLength 屬性，可增加此配額。 第 64 行，位置為 79。
WCF字符串過(guò)長(zhǎng)問(wèn)題主要是maxStringContentLength和maxReceivedMessageSize的設(shè)置會(huì)影響到消息的發(fā)送和接收，于是全部改為2MB大小，即2097152。
客戶(hù)端app.config修改以解決WCF字符串過(guò)長(zhǎng)問(wèn)題：
- < 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" maxName
TableCharCount="16384" /> - < security mode="None">
- < transport clientCredentialType="None"
proxyCredentialType="None" - realm="" />
- < message clientCredentialType="UserName"
algorithmSuite="Default" /> - < /security>
- < /binding>
- < /basicHttpBinding>
- < /bindings>
服務(wù)端web.config修改解決WCF字符串過(guò)長(zhǎng)問(wèn)題：
- < system.serviceModel>
- < !-- add for the message size -->
- < bindings>
- < basicHttpBinding>
- < binding name="NewBinding2MB"
maxReceivedMessageSize="2097152">- < readerQuotas maxString
ContentLength="2097152" />- < /binding>
- < /basicHttpBinding>
- < /bindings>
- < !-- add for the message size -->
- < behaviors>
- < serviceBehaviors>
- < behavior name="Web.WCF.
ShareServiceBehavior">- < serviceMetadata httpGetEnabled="true"/>
- < serviceDebug includeException
DetailInFaults="false"/>- < /behavior>
- < /serviceBehaviors>
- < /behaviors>
- < serviceHostingEnvironment aspNet
CompatibilityEnabled="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>
