【问题描述】：

我有客户端提供的 WSDl，我需要根据它创建 WCF 服务

它在我尝试使用以下配置在 WCF 中实现的 soap 1.2 下没有提供任何肥皂动作

当我尝试使用soap UI提交和应用程序时，我收到以下错误

<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope">

This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver.  Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).</s:Text>

【解决方案1】：

有various interpretations如果没有指定soapAction怎么办（例如可能有默认soapaction）。我建议设置 wcf 客户端和服务器，看看客户端发送了什么soapAction。这是所有客户端都应该发送的soapAction。
