今天又看到"這可能是由於服務終結點綁定未使用 HTTP 協議造成的" 這個蛋疼的錯誤
這個錯誤之前也遇到過多次 歸納原因有
1、沒有重新生成代理文件
2、這是因為WCF返回值無法序列化造成的
但我今天遇到時 我想這次肯定不是這兩個原因之一 我想應該是數據量過大 於是把數據減少一部分后 一切正常 那就找解決方案 最后看到 這個帖子 http://topic.csdn.net/u/20080708/08/8158eac6-08fd-4e04-b37d-7dfc8137a6d9.html?seed=937996111&r=60490402#r_60490402 按文中的配置方法配置后 問題解決。
既然是好東西 那我就“偷”來 呵呵
解決方法：
用SvcConfigEditor為客戶端和服務端都加上一個behavior (服務端添加servicehehavior, 客戶端添加endpointbehavior),然后為這兩個服務各添加一個dataContractSerializer,把他的maxItemsInObjectGraph字段變成更大的數。
服務端配置：
<system.serviceModel>
<diagnostics>
<messageLogging logMalformedMessages="true" logMessagesAtServiceLevel="true"
logMessagesAtTransportLevel="true" />
</diagnostics>
<behaviors>
<serviceBehaviors>
<behavior name="NewBehavior">
<serviceMetadata httpGetEnabled="true" httpGetUrl="http://localhost:8000/ContactManager/md" />
<serviceDebug includeExceptionDetailInFaults="true" />
<dataContractSerializer maxItemsInObjectGraph="65536000" /> </behavior>
</serviceBehaviors>
</behaviors>
<services>
<service behaviorConfiguration="NewBehavior" name="WcfServiceLibrary1.ContactManager">
<endpoint address="http://localhost:8000/ContactManager" binding="wsHttpBinding"
bindingConfiguration="NewBindingStationCnfg" contract="WcfServiceLibrary1.IContactManager" />
<endpoint address="http://localhost:8000/ContactManager/mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<bindings>
<wsHttpBinding>
<binding name="NewBindingStationCnfg" maxReceivedMessageSize="483647" />
</wsHttpBinding>
</bindings>
</system.serviceModel>
客戶端的config:
<system.serviceModel>
<behaviors>
<endpointBehaviors>
<behavior name="NewBehavior">
<dataContractSerializer maxItemsInObjectGraph="6553600" />
</behavior>
</endpointBehaviors> </behaviors>
