这里有一份C#控制台客户端和服务器端代码样例(虽然它们在同一示例中,但仅用于演示目的)使用HTTPS。
对于客户端,我们重用SoapHttpClientProtocol
类,但是对于服务器端,不幸的是,我们不能重用任何东西,因为类完全绑定到ASP.NET的(IIS)HttpContext
类。
对于服务器端,我们使用HttpListener
,因此,根据您的配置,服务器端可能需要管理员权限才能调用HttpListener
的Prefixes.Add(url)
。
该代码未使用客户端证书,但可以在我放置// TODO注释的位置添加。
代码假定与使用的url和端口关联的证书。如果没有(使用 netsh http show sslcert
转储所有相关证书),则可以使用此处描述的过程来添加一个:https://dev59.com/Hmgu5IYBdhLWcg3wU1qN#11457719
