c＃.net4 webRequest通過SSL不起作用

Question

嗨這工作時發佈到http地址，但發佈到HTTPS地址發佈失敗，無法建立信任關係！

我需要做些什麼或這是一個服務器錯誤！？

private static string HttpPost (string uri, string parameters) 
{ 
    //return "ok"; 
    // parameters: name1=value1&name2=value2  
    try 
    { 
     WebRequest webRequest = WebRequest.Create(uri); 

     webRequest.ContentType = "application/x-www-form-urlencoded"; 
     webRequest.Method = "POST"; 
     byte[] bytes = Encoding.ASCII.GetBytes(parameters); 
     Stream os = null; 
     try 
     { // send the Post 
      webRequest.ContentLength = bytes.Length; //Count bytes to send 
      os = webRequest.GetRequestStream(); 
      os.Write(bytes, 0, bytes.Length);   //Send it 
     } 
     catch (WebException ex) 
     { 
      MessageBox.Show(ex.Message, "HttpPost: Request error", 
       MessageBoxButtons.OK, MessageBoxIcon.Error); 
     } 
     finally 
     { 
      if (os != null) 
      { 
       os.Close(); 
      } 
     } 

     try 
     { // get the response 
      WebResponse webResponse = webRequest.GetResponse(); 
      if (webResponse == null) 
      { return null; } 
      StreamReader sr = new StreamReader(webResponse.GetResponseStream()); 
      return sr.ReadToEnd().Trim(); 
     } 
     catch (WebException ex) 
     { 
      MessageBox.Show(ex.Message, "HttpPost: Response error", 
       MessageBoxButtons.OK, MessageBoxIcon.Error); 
     } 
    } 
    catch 
    { 

    } 
    return null; 
} // end HttpPost 

Answer 1

SSL證書已過期或無效。在服務器上部署新的有效SSL證書。

Answer 2

或者明確地信任證書，如果這是正確的事情。
