SSL 證書錯誤：certificate_unknown

我想創建推送通知伺服器，在伺服器中安裝 SSL 證書和 .p12 文件時，我們遇到以下錯誤：我想知道 ssl 證書有什麼問題，因為我收到了 certificate_unknown 錯誤。

main, RECV TLSv1 ALERT:  fatal, certificate_unknown
main, called closeSocket()
main, handling exception: javax.net.ssl.SSLHandshakeException: Received fatal alert: certificate_unknown
Error pushing notification(s):
Invalid certificate chain (Received fatal alert: certificate_unknown)!  Verify that the keystore you provided was produced according to specs...

               // TODO Auto-generated catch block
               e.printStackTrace();
           }

       }


}

將私鑰作為客戶端請求載入到 SSL 套接字是不常見的。我個人認為你應該載入公鑰。私鑰由伺服器端的 SSL 套接字載入。您需要私鑰的唯一原因是充當伺服器並接受來自另一端的連接，但您似乎沒有這樣做。

這可能解釋了“格式錯誤的證書”消息。

在參照：

private static String certificate = "D:/./trunk/Development/JavaPNS/src/com/applicationname/pns/privateKey.p12"
