无法使用 Javapns/Javaapns SSL 握手失败发送推送通知 [英] Cannot send push notifications using Javapns/Javaapns SSL handshake failure

问题描述

我有推送通知问题.我有一个由团队成员创建的 p.12 证书，并且我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 javaapns 库，结果相同)但我不断收到此错误:

I have an issue with push notifications. I have a p.12 certificate that was created by a team member and I have the device token for the device to be pushed to. I am using the javapns library to do the push (also tried the javaapns lib with same results) but I keep getting this error:

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，但导入也失败了.我正在 Windows 机器上使用 eclipse 进行开发.

I read and tried the suggestions from several of the other posts including importing the certificate into cacerts keystore but the import fails as well. I am developing using eclipse on a windows machine.

有人熟悉这个问题吗?我刚开始使用 ssl，所以可能是我做错了什么，还是我无法使用在另一台机器上生成的证书?

Anyone familiar with this issue? I am new to using ssl so perhaps I'm doing something wrong or is it that I cannot use a certificate generated on another machine?

推荐答案

我是一个新的 iOS 开发者，我之前也遇到过同样的问题.

I am a new iOS developer and I had the same issue before.

最后发现问题出在p12证书上.我们不应该使用私钥 p12 文件，而是应该从您的私钥和从 Apple 下载的证书生成 p12.

I finally found that the problem was due to the p12 certificate. We should not use the private key p12 file, instead we should generate a p12 from your private key and the cert download from Apple.

请执行以下 OpenSSL 命令以获取正确的 p12 文件:

Please execute the following OpenSSL command to get the correct p12 file:

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，您应该使用iphone_dev.p12与苹果服务器进行通信.

After that, you should use iphone_dev.p12 to communicate with apple server.
