HttpWebrequest 失败，内部异常身份验证失败，因为远程方已关闭传输流 [英] Failure on HttpWebrequest with inner exception Authentication failed because the remote party has closed the transport stream

问题描述

使用 C#、.Net 4.5，我正在尝试通过远程服务器上的 HttpWebRequest 发送 Web 请求.请看下面的代码.我尝试了一些论坛建议的大多数解决方案，但我总是以同样的错误告终.请参阅下面的堆栈跟踪.调用request.GetReponse()方法时抛出错误.

附加信息，基本上，我正在尝试调用安装在远程服务器上的 vmware 的 vCenter 组件的 reloadSslCertificate 函数.目前，该错误仅发生在 vCenter 5.5 上.它在 5.1 及以下版本中运行良好.

 var uri = String.Format("https://{0}/some_url", serverName);var request = (HttpWebRequest)WebRequest.Create(uri);request.KeepAlive = true;request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";request.Headers.Set(HttpRequestHeader.AcceptLanguage, "en-US,en;q=0.8");request.Credentials = 凭证；request.CookieContainer = cookieContainer;var response = request.GetResponse();

提前致谢.

解决方案

我只想分享这个问题已经解决了.

我只是在发出网络请求之前修改了设置安全协议的代码部分.

发件人:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

收件人:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 |安全协议类型.Tls;

事实证明，vCenter 5.5 在其配置中使用 TLS 作为其 SSL 协议.我希望人们在遇到同样的问题时会发现这对他们有所帮助.

Using C#, .Net 4.5, I'm trying to send out a web request through HttpWebRequest on a remote server. Please see the code below. I tried most of the solutions suggested by some forums but I always end up with the same error. Please see the stack trace below. The error is thrown when calling the request.GetReponse() method.

Additional info, basically, I'm trying to call the reloadSslCertificate function of vmware's vCenter component installed on a remote server. Currently, the error only happens on vCenter 5.5. It works fine in versions 5.1 and below.

        var uri = String.Format("https://{0}/some_url", serverName);
        var request = (HttpWebRequest)WebRequest.Create(uri);
        request.KeepAlive = true;
        request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
        request.Headers.Set(HttpRequestHeader.AcceptLanguage, "en-US,en;q=0.8");
        request.Credentials = credential;
        request.CookieContainer = cookieContainer;


        var response = request.GetResponse();

Exception : System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Authentication failed because the remote party has closed the transport stream. 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.CheckCompletionBeforeNextReceive(ProtocolToken message, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslState.ProcessAuthentication(LazyAsyncResult lazyResult) at System.Net.TlsStream.CallProcessAuthentication(Object state) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) 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) --- End of inner exception stack trace --- at System.Net.HttpWebRequest.GetResponse()

Thanks in advance.

解决方案

I just want to share that this issue has already been resolved.

I just modified the part of the code where I set the security protocol before issuing the web request.

From:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

To:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls;

As it turned out, vCenter 5.5 uses TLS as its SSL protocol in its configuration. I hope people may find this helpful when they encounter this same issue.
