413實體太大異常，WCF服務

Question

我的代碼因以下異常而崩潰：

mscorlib.dll中發生了類型為'System.ServiceModel.ProtocolException'的未處理異常

附加信息：遠程服務器返回了意外的響應：（413）請求實體太大。

這是我的web.config文件：

<?xml version="1.0"?>
<configuration>
  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>

          </baseAddresses>
        </host>
      </service>
    </services>

這是我的客戶端app.config文件：

        <identity>
          <userPrincipalName value="Administrator" />
        </identity>

    </client>

    <bindings>

        </binding>
      </wsHttpBinding>
    </bindings>
  </system.serviceModel>
</configuration>

我沒看到什么？

在此先感謝您的幫助。

一個問題是，您永遠不會將在服務配置中定義的綁定分配給端點，因此服務將使用wsHttpBinding的默認值。 嘗試通過bindingConfiguration屬性將“ SafeServiceConf”綁定配置分配給端點：

<endpoint address="wsHttp" 
          binding="wsHttpBinding"
          bindingConfiguration="SafeServiceConf"
          contract="WcfService1.IService1" />

然后，服務將使用您指定的值，而不是默認值。
