无法使用Javapns / Javaapns SSL握手失败发送推送通知

Question

我的推送通知有问题。我有一个由团队成员创建的p.12证书，并且我拥有要推送到的设备的设备令牌。我正在使用javapns库进行推送（也尝试了具有相同结果的javaapns
lib），但我一直收到此错误：

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

这是我用来测试的代码

try {
    List<PushedNotification> n = Push.combined(text, 20, null, file, "********", false, token);

    for (PushedNotification notification : n) {
        if (notification.isSuccessful())  
            System.out.println("Push notification sent successfully to: " + notification.getDevice().getToken());
        else {
            String invalidToken = notification.getDevice().getToken();

            Exception theProblem = notification.getException();
            theProblem.printStackTrace();

            ResponsePacket theErrorResponse = notification.getResponse();
            if (theErrorResponse != null)
                System.out.println(theErrorResponse.getMessage());
        }
    }
}
catch (CommunicationException e)  {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
catch (KeystoreException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

我阅读并尝试了其他几篇文章中的建议，包括将证书导入cacerts密钥库，但导入也失败。我正在Windows机器上使用Eclipse开发。

有人熟悉这个问题吗？我是使用ssl的新手，所以也许我做错了什么，还是无法使用在另一台计算机上生成的证书？

我是一名新的iOS开发人员，之前也遇到过同样的问题。

我终于发现问题是由引起的p12 certificate。我们不应该使用私钥p12文件，而是应该根据您的私钥和从Apple下载的证书生成p12。

请执行以下OpenSSL命令以获取正确的p12文件：

developer_identity.cer <= download from Apple
mykey.p12 <= Your private key

openssl x509 -in developer_identity.cer -inform DER -out developer_identity.pem -outform PEM
openssl pkcs12 -nocerts -in mykey.p12 -out mykey.pem
openssl pkcs12 -export -inkey mykey.pem -in developer_identity.pem -out iphone_dev.p12

之后，您应该用于iphone_dev.p12与Apple服务器进行通信。
