WCF在增加郵件時仍然會收到最大郵件大小錯誤

Question

我剛剛研究了很多主題，無法找出原因，但我仍然遇到此問題。 我在服務器上的配置。

<?xml version="1.0" encoding="utf-8"?> 
<configuration> 
    <appSettings> 
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true"/> 
    </appSettings> 
    <system.web> 
    <compilation debug="true"/> 
    </system.web> 
    <system.serviceModel> 
    <services> 
     <service name="MyService.Services.Service"> 
     <endpoint behaviorConfiguration="LargeDataBehavior" address="" binding="wsHttpBinding" contract="MyService.Services.UI.IService" bindingConfiguration="MyBinding"> 
      <identity> 
      <dns value="localhost"/> 
      </identity> 
     </endpoint> 
     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
     <host> 
      <baseAddresses> 
      <add baseAddress="http://localhost:8733/MyService.Services/Service/"/> 
      </baseAddresses> 
     </host> 
     </service> 
    </services> 
    <bindings> 
     <wsHttpBinding> 
     <binding bypassProxyOnLocal="True" name="MyBinding" textEncoding="utf-8" 
       maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647"> 
      <readerQuotas maxDepth="2147483647" 
        maxStringContentLength="2147483647" 
        maxArrayLength="2147483647" 
        maxBytesPerRead="2147483647" 
        maxNameTableCharCount="2147483647" /> 
      <security mode="None"> 
      <transport clientCredentialType="None" proxyCredentialType="None" realm=""/> 
      <message clientCredentialType="UserName" algorithmSuite="Default"/> 
      </security> 
     </binding> 
     </wsHttpBinding> 
    </bindings> 
    <behaviors> 
     <endpointBehaviors> 
     <behavior name="LargeDataBehavior"> 
      <dataContractSerializer maxItemsInObjectGraph="2147483646" /> 
     </behavior> 
     </endpointBehaviors> 
     <serviceBehaviors> 
     <behavior> 
      <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/> 
      <serviceDebug includeExceptionDetailInFaults="True"/> 
      <dataContractSerializer ignoreExtensionDataObject="false" maxItemsInObjectGraph="2147483646" /> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    </system.serviceModel> 

    <startup> 
    <supportedRuntime version="v2.0.50727"/> 
    </startup> 
</configuration> 

然後我運行WCF Test Client。

傳入消息的最大消息大小配額（65536）已被超出。要增加配額，請在適當的綁定元素上使用MaxReceivedMessageSize屬性。

內部異常： 傳入消息的最大消息大小配額（65536）已被超出。要增加配額，請在適當的綁定元素上使用MaxReceivedMessageSize屬性。

對不起，我的英語不好。 非常感謝您的幫助！

Answer 1

基於錯誤，這聽起來像你需要增加maxReceivedMessageSize屬性在WCFTestClient配置，而不是服務。

爲此，請轉到WCFTestClient左側的底部並右鍵單擊配置文件節點，然後選擇「使用SvcConfigEditor編輯」。

在彈出的窗口中選擇要編輯的結合，並根據需要在右側窗格中，您可以調整所有的值。

注意，這隻會堅持認爲WCFTestClient會議;一旦你關閉它，你會失去設置，它會恢復到默認值。

Answer 2

似乎配置對服務不正確，因爲在端點級別應用綁定配置後，它仍然給最大大小提供同樣的問題。 您的綁定配置是正確的，但行爲配置應該位於服務級別而不是終點級別。

將behaviorConfiguration="newBehaviour"行爲添加到服務級別節點，即'<services>'標記，並且您可以刪除端點標記上的行爲，因爲行爲是服務級別，因此請在服務標記上指定您的行爲配置。

<system.serviceModel> 
    <services name="MyService.Services.Service" behaviorConfiguration="newBehaviour" > 
    <endpoint address="" binding="wsHttpBinding" contract="MyService.Services.UI.IService" bindingConfiguration="MyBinding"> 
      <identity> 
       <dns value="localhost" /> 
      </identity> 
     </endpoint><endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
     <host> 
      <baseAddresses> 
       <add baseAddress="http://localhost:8733/MyService.Services/Service/" /> 
      </baseAddresses> 
     </host> 
     </service> 
    </services> 
    <bindings> 
     <wsHttpBinding> 
     <binding bypassProxyOnLocal="True" name="MyBinding" textEncoding="utf-8" maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647"> 
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> 
      <security mode="None"> 
       <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> 
       <message clientCredentialType="UserName" algorithmSuite="Default" /> 
      </security> 
     </binding> 
     </wsHttpBinding> 
    </bindings> 
    <behaviors> 
     <endpointBehaviors> 
     <behavior name="LargeDataBehavior"> 
      <dataContractSerializer maxItemsInObjectGraph="2147483646" /> 
     </behavior> 
     </endpointBehaviors> 
     <serviceBehaviors> 
     <behavior name="newBehaviour"> 
      <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True" /> 
      <serviceDebug includeExceptionDetailInFaults="True" /> 
      <dataContractSerializer ignoreExtensionDataObject="false" maxItemsInObjectGraph="2147483646" /> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors>
