asmx网络服务，带有附件的soap请求

• 问答

这是我的第一篇文章，所以如果我的问题没有达到标准，请不要苛刻：）

我在使用asmx设置Web服务时遇到问题。 Web服务在IIS上运行。 主要问题是带有附件的SOAP请求。这些请求以“多部分/相关”的形式发送。 IIS在接收带有此格式（多部分/相关格式）的数据的请求时返回错误。停留在不支持此类数据的错误状态。

所以我的问题是，此错误是否是IIS配置，asmx限制或其他原因造成的？

WSDL看起来像这样：

zhang_alex34 回答：asmx网络服务，带有附件的soap请求

一段时间后，我找到了解决方案。 因此，asmx不支持多部分/相关请求。但是，您可以使用一种称为“肥皂扩展”的东西。这样，您可以在请求到达实际服务之前捕获请求并对其进行处理。您也可以根据需要做出任何回应。
