动态调用受WS-Security保护的web服务

Question

我正在开发一个用.Net 4.5.1编写的客户端软件。该软件支持调用不同的web服务，其中有些是由WS-Security保护的，有些则不是。

有没有什么方法可以发送嵌入了WS-Security的请求，而不是嵌入WS-Security的请求？

非常感谢

您调用的每个服务在应用程序的配置文件中都有自己的配置节。

下面是从the MSDN article 'Client Configuration'复制的示例app.config。请注意，您调用的每个服务都有一个endpoint元素，并且每个endpoint元素都可以引用binding配置。WS-security配置是在绑定元素上完成的，有关here安全性的文档，请参阅WCF。基本上，您必须将安全模式设置为Message，才能对请求和响应使用WS-security加密。
