413 请求实体太大错误 - WCF 服务

Question

我有一个 wcf 服务，当我把请求消息放入大数据时（我有一个请求包括 base64 字符串，这个请求是一个长文本）
我收到此错误“413 请求实体太大”。
帮我调用此服务。
这是我的 wcf 配置

Answer 1

您增加了绑定属性的大小，但您从未将该绑定分配到端点，因此 WCF 使用指定绑定的默认值。要解决此问题，请在服务配置中的 <endpoint> 元素上使用 bindingConfiguration 属性，如下所示：

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

请注意，您的客户端配置已将指定的绑定分配给客户端端点。
