Silverlight 調用WCF常見錯誤Silverlight wcf 上傳大資料

 

錯誤1 

錯誤描述：The remote server returned an error: NotFound

可能原因：WCF服務本身對資料包進行了限制，最大不能超過65535，Silverlight發送大資料包到伺服器端(例片直接存於資料庫)，   WCF返回以上錯誤。

傳輸時,最好用List<string> 代替 string做參數。

解決方案：

（1）修改Silverlight端ServiceReferences.ClientConfig檔案，增加Buffer 尺寸。
  <bindings> 
      <basicHttpBinding> 
                <binding name="BasicHttpBinding_IDataService" 
                         maxBufferSize="2147483647" 
                         maxReceivedMessageSize="2147483647"> 
                    <security mode="None" /> 
                </binding> 
       </basicHttpBinding> 
</bindings>

 

         System.ServiceModel.BasicHttpBinding binding = new System.ServiceModel.BasicHttpBinding(System.ServiceModel.BasicHttpSecurityMode.None);
            binding.MaxReceivedMessageSize = int.MaxValue;
            binding.MaxBufferSize = int.MaxValue;
            binding.ReceiveTimeout = TimeSpan.FromMinutes(5);
            binding.SendTimeout = TimeSpan.FromMinutes(5);
            binding.CloseTimeout = TimeSpan.FromMinutes(5);
            binding.OpenTimeout = TimeSpan.FromMinutes(5);
            EndpointAddress ep = new EndpointAddress("../DataService.svc");
            MyTest.DataService.DataServiceClient client = new DataServiceClient(binding,ep);

（2）修改伺服器端，在Web.config中添加自訂BasicHttpBinding對象，

 

　伺服器端：web.config

<configuration>
  <appSettings>
    <add key="ReturnTablePath" value="C:\TestData\test_data.csv"/>
  </appSettings>
    <system.web>
      <httpRuntime maxRequestLength="2147483647"/>
      <compilation debug="true" targetFramework="4.0" />
    </system.web>

  <system.serviceModel>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
    <behaviors>
      <serviceBehaviors>
        <behavior name="MappingDataEditor.Web.DataServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
          <dataContractSerializer maxItemsInObjectGraph="2147483647" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="MappingDataEditor.Web.DataServiceBehavior" name="MappingDataEditor.Web.DataService">
        <!--name=命名空間(ExcelServer)+類名(Server1)-->
        <endpoint address="" bindingConfiguration="LargeBuffer" binding="basicHttpBinding" contract="MappingDataEditor.Web.IDataService"/>
        <!--contract=命名空間(ExcelServer)+介面(IServer1)-->
      </service>
    </services>
    <bindings>
      <basicHttpBinding>
        <binding name="LargeBuffer" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <!--name=隨意命名-->
          <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647"/>
          <security mode="None"></security>
        </binding>
      </basicHttpBinding>
    </bindings>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>
