我使用HttpWebRequest訪問其餘網站時,出現"請求被停止：沒法創建 SSL / TLS安全通道"錯誤,因而goog和百度了一番,提供的答案基本是:ServicePointManager.ServerCertificateValidationCallback寫委託安全

 
         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,該出現的錯誤仍是繼續出現.網站

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

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