APNS - 无法使用 Java 向 iOS 设备发送通知

Question

我需要让它工作，但我完全没有选择...任何帮助将不胜感激。

我正在尝试使用 Java 向我的 iOS 设备发送通知，并且遵循了许多教程和论坛帖子，主要是这些：raywenderlich.com, JavaPNS Basic Example 和 java-apns 示例如下所示。

不过，我可以使用 PHP 发送通知。有人能看到我做错了什么吗？我已经为此工作了好几天，但无法弄清楚问题是什么 b/c 我已经复制了其他人声称有效的确切代码。这是我的代码：

public static void main(String[] args) {
    try {
        // Not my real token
        String token = "2919333333333545F19B427AE7E98307B1B2AA9390A38BC0E533E77E11111111";
        ApnsService service = APNS.newService()
                .withCert("C://code//Dev.p12", "password")  // (path to cert, password)
                .withSandboxDestination()
                //.withProductionDestination()
                .build();

        //System.out.println("Testing the connection...");
        //service.testConnection();
        //System.out.println("...Successful!");

        String payload = APNS.newPayload()
                .alertBody("Java test message!")
                .sound("default")
                .build();

        System.out.println("About to send the message...");
        service.push(token, payload);
        System.out.println("...message sent!");
    } catch (Exception e) {
        e.printStackTrace();
    }
}

这是我得到的异常：

当我输入错误的密码时，我会收到错误密码的异常，因此我知道它正在查找 .p12 文件。我可以使用我在网上找到的 PHP 示例发送通知，但是 Java 代码中一定有我遗漏的东西。我已经尝试了 java-apns 库（如上所示）和 JavaPNS 库，我得到了相同的结果。

我们不应该使用私钥 p12 文件，而应该从您的私钥和从 Apple 下载的证书生成一个 p12。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
