HttpWebRequest 15秒延遲性能問題

2011-09-07 351 views

我有一個C＃Windows應用程序作爲「NT AUTHORITY \ Network Service」運行，需要通過HTTPS向託管在Apache Tomcat上的服務器發出POST請求。我使用HttpWebRequest發出請求。我通過設置ServicePointManager.ServerCertificateValidationCallback委託來接受服務器證書。調用HttpWebRequest.GetRequestStream（）和調用ServerCertificateValidationCallback回調之間有很長的延遲（約15秒）。HttpWebRequest 15秒延遲性能問題

當我運行與LocalSystem相同的代碼時，它工作正常，沒有延遲。可能會出現什麼問題？

事情我試過到目前爲止：

  • 通過設置request.Proxy = null，並且通過設置defaultProxy啓用了的app.config = 「假」
  • 設置request.ServicePoint.Expect100Continue =禁用代理假
  • 設置ServicePointManager.CheckCertificateRevocationList =假
  • ServicePointManager.Expect100Continue =假

================================================ ========================

這似乎沒有工作。在HttpWebRequest.GetRequestStream（）中仍然有15秒的一致延遲。還收集System.Net跟蹤。

代碼：

 ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateRemoteCertificate); 

     ServicePointManager.Expect100Continue = false; 

     ServicePointManager.CheckCertificateRevocationList = false; 





    public static bool ValidateRemoteCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors policyErrors) 

    { 

     Trace.TraceInformation("HttpWebClient.ValidateRemoteCertificate: Implicitly allowing SSL certificate"); 

     return true; 

    }

Web客戶機：

 HttpWebRequest request = (HttpWebRequest) HttpWebRequest.Create(uri); 

     request.KeepAlive = false; 

     request.ProtocolVersion = HttpVersion.Version11; 

     request.Method = "POST"; 

     request.Proxy = null; 

     request.AuthenticationLevel = AuthenticationLevel.None; 

     request.AllowWriteStreamBuffering = false; 

     request.ServicePoint.Expect100Continue = false; 



     byte[] postBytes = Encoding.ASCII.GetBytes(post_data); 



     request.ContentType = "application/x-www-form-urlencoded"; 

     request.ContentLength = postBytes.Length; 



     try 

     { 

      Stream requestStream = request.GetRequestStream(); 



      Trace.TraceInformation("HttpWebClient.SendRequest Sending request of length {0}...", postBytes.Length); 

      requestStream.Write(postBytes, 0, postBytes.Length); 

      Trace.TraceInformation("HttpWebClient.SendRequest Request sent"); 

      requestStream.Close(); 

     } 

     catch (Exception e) 

     { 

      Trace.TraceInformation("HttpWebClient.sendRequest: exception {0}, {1}", e.Message, e.StackTrace); 

     } 



     Trace.TraceInformation("HttpWebClient.SendRequest Fetching HTTP response..."); 

     HttpWebResponse response; 

     response = (HttpWebResponse)request.GetResponse();

System.net痕跡： 從痕跡，15秒的延遲是從2011-09-07T21：42： 16.7796885Z至2011-09-07T21：42：31.7897095Z。報告的錯誤爲： 遠程證書有錯誤：，證書名稱不匹配。證書鏈已處理，但終止於信任提供程序不信任的根證書。

當您使用LocalSystem時，跟蹤是什麼？它會拋出同樣的錯誤嗎？ – TheCodeKing

的延遲是在網絡日誌可見...

DateTime=2011-09-07T21:42:16.7696885Z System.Net Information: 0 :

[0412]的InitializeSecurityContext（憑證= System.Net.SafeFreeCredential_SECURITY，上下文= 4b0cd8：12d34d0， 目標名稱= 172.16.2.142，inFlags = ReplayDetect，SequenceDetect， Confidentiality，AllocateMemory，InitManualCredValidation） DateTime = 2011-09-07T21：42：16.7696885Z System.Net信息：0： [04 12] InitializeSecurityContext（In-Buffers count = 2，Out-Buffer length = 0，返回代碼= OK）。 DateTime = 2011-09-07T21：42：16.7696885Z系統。網絡信息：0： [0412]遠程證書：[版本] V3

這樣：

DateTime=2011-09-07T21:42:31.7897095Z System.Net Information: 0 :

[0412] SecureChannel＃46104728 - 證書名稱不匹配。 DateTime = 2011-09-07T21：42：31.7897095Z System.Net信息：0： SecureChannel＃46104728 - 證書鏈已處理，但 終止於不受信任提供商信任的根證書。

DateTime=2011-09-07T21:42:31.7897095Z System.Net Information: 0 :

[0412] SecureChannel＃46104728 - 遠程證書驗證爲 用戶有效。 * *

是否有可能在網絡服務帳戶，您的代理設置等配置不正確，所以Schannel中不能獲得證書吊銷列表，以及做其他事情（如散步根證書鏈）來快速驗證證書？

當作爲網絡服務運行時，使用Wireshark進行網絡嗅探。這會告訴你發生了什麼事。當然，由於SSL的原因，這將是一句胡言亂語，但您至少應該能夠看到明文傳出的CRL和根證書的HTTP請求。

終於找到根本原因。這裏是：

在ssl連接期間，調用windows update來更新根證書。這需要互聯網連接。如果機器連接到互聯網，則不會出現延遲。如果機器未連接到互聯網，則會看到15秒的延遲，因爲這是更新的根證書的網絡檢索的默認超時值。

這是按設計而定，而不是根據以下來自Microsoft的知識庫文章的錯誤。 http://support.microsoft.com/kb/317541

我遇到了一個類似的問題，沒有互聯網訪問的服務器。解決方案是禁用自動根證書更新並將crl列表的超時降低到一秒。
要做到這一點。

開始輸入gpedit.msc - >本地計算機策略 - >計算機配置 - >管理模板 - >系統 - > Internet通信管理 - > Internet通信設置 - >關閉自動根證書更新=啓用

而

啓動gpedit.msc - >本地計算機策略 - >計算機配置 - > Windows設置 - >安全設置 - >公鑰策略 - >證書路徑驗證路徑。 選擇標籤「網絡檢索」並啓用「定義這些策略設置」。取消選擇「自動更新根...」 最重要的是將超時值設置爲1.
