【中文标题】HTTP Get 请求错误“身份验证失败，因为远程方已关闭传输流。”

【英文标题】：HTTP Get request error "Authentication failed because the remote party has closed the transport stream."

【问题描述】：

当我尝试从我的 .net 3.5 winform 应用程序调用 rest webservice(HTTP get) 时，我收到以下错误：

     `Authentication failed because the remote party has closed the transport stream. 
StackTrace:    at System.Net.Security.SslState.StartReadFrame(Byte[] buffer, Int32 readBytes, AsyncProtocolRequest asyncRequest)
       at System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest)
       at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest)
       at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult)
       at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
       at System.Net.TlsStream.ProcessAuthentication(LazyAsyncResult result)
       at System.Net.TlsStream.Write(Byte[] buffer, Int32 offset, Int32 size)
       at System.Net.PooledStream.Write(Byte[] buffer, Int32 offset, Int32 size)
       at System.Net.ConnectStream.WriteHeaders(Boolean async)`

从浏览器运行时请求运行良好。 那么，问题是否与使用更高 tls 协议的服务器有关，而 .net 3.5 不支持该协议？ 这是我调用网络服务的代码：

XElement response = XElement.Load(url);

【参考方案1】：

是的，最可能的原因是 Web 服务器 TLS 1.2。如果您无法升级您的 .net 框架，那么这可能会有所帮助：https://github.com/juhovh/AaltoTLS 顺便说一句，我没有使用过这个第三方代码，也不认可它 - 由你来决定它的适用性。
