413請求實體太大錯誤-WCF服務

Question

當我放置大容量數據的請求消息時，我有一個wcf服務（我的請求包含base64字符串，並且此請求是長文本）
我收到此錯誤“ 413請求實體太大”。
幫我打電話給這項服務。
這是我的WCF配置

您增加了綁定屬性的大小，但從未將綁定分配給端點，因此WCF使用指定綁定的默認值。 要解決此問題，請在服務的配置中使用<endpoint>元素上的bindingConfiguration屬性，如下所示：

<endpoint address="soap" 
          binding="basicHttpBinding" 
          bindingConfiguration="ServiceSoap"
          contract="ApiFrame.IApiframe" />

請注意，您的客戶端配置已將指定的綁定分配給客戶端端點。
