C＃Web服务客户端独立计算每个安全标头元素

Question

我正在尝试手动创建一个肥皂信封，并尝试创建如下所示的安全标头。 由于Web服务服务器端对名称空间进行了严格的验证，因此请求始终会失败，并显示“无效的安全标题错误”。 C＃.NET中是否有一种方法可以逐行形成整个Signature元素。 以下是我期望的输出XML。

Answer 1

通常，这应该通过一些基础结构代码（例如WCF客户端绑定（或旧的WSE扩展）或某些其他Ws-Security库）来完成。

但是，如果必须的话，可以使用System.Security中的SignedXml类。

https://msdn.microsoft.com/zh-cn/library/system.security.cryptography.xml.signedxml(v=vs.110).aspx

您需要遵循一个严格的工作流程（元素引用，转换，规范化，哈希算法，密钥算法，密钥类型），并且通常取决于服务，该服务是设置规则的一个。

这些特性实际上是大多数开发人员世界讨厌 SOAP并开始使用REST的原因。
