關於解決 請求被中止：無法建立SSL / TLS安全通道(The request was aborted: Could not create SSL/TLS secure channel)的問題

我使用HttpWebRequest訪問其他網站時,出現"請求被中止：無法建立SSL / TLS安全通道"錯誤,於是goog和百度了一番,提供的答案基本是:ServicePointManager.ServerCertificateValidationCallback寫委託

public ResponseModel GetHtml(string url){ServicePointManager.ServerCertificateValidationCallback = ValidateServerCertificate;HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);}private bool ValidateServerCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors){return true;}

 但這種方法對我無效,該出現的錯誤還是繼續出現.

最終解決辦法是,在訪問url前執行語句  ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;即可

public ResponseModel GetHtml(string url) {     ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3; 　　　HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); } 

 整個世界安靜多了.哈哈
