SSL握手通过Java的苹果推送通知服务器 [英] SSL handshake with Apple Push Notification Server via Java

问题描述

您好，我尝试发送推送消息到使用Java我的设备。但我'建立SSL连接时获得媒体链接的问题。
这里是code迄今：

Hello I am trying to send a push message to my device using Java. But I'am allready getting problems when establishing the ssl connection. Here is the code so far:

        KeyStore keyStore = KeyStore.getInstance("PKCS12");

        InputStream key = getClass().getResourceAsStream("apns-dev-key.p12");
        char[] c = key.toString().toCharArray();

        keyStore.load(getClass().getResourceAsStream("apns-dev-cert.p12"), c);
        KeyManagerFactory keyMgrFactory = KeyManagerFactory.getInstance("SunX509");
        keyMgrFactory.init(keyStore, c);

        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(keyMgrFactory.getKeyManagers(), null, null);
        SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

        SSLSocket sslSocket = (SSLSocket) sslSocketFactory.createSocket(host, port);
        String[] cipherSuites = sslSocket.getSupportedCipherSuites();
        sslSocket.setEnabledCipherSuites(cipherSuites);
        sslSocket.startHandshake();

我得到的错误是：

The error I am getting is:

java.io.IOException: failed to decrypt safe contents entry: javax.crypto.BadPaddingException: Given final block not properly padded

我想有一些问题与APNS-DEV-ke​​y.p12文件。任何提示？

I guess there is some problem with the apns-dev-key.p12 file. Any hints?

推荐答案

下面我工作的例子：

private String token = "<token>";
private String host = "gateway.sandbox.push.apple.com";
private int port = 2195;

private String payload = "{\"aps\":{\"alert\":\"Message from Java o_O\"}}";

public APNSender() {
    try {
        KeyStore keyStore = KeyStore.getInstance("PKCS12");

        keyStore.load(getClass().getResourceAsStream("cert.p12"), "<password>".toCharArray());
        KeyManagerFactory keyMgrFactory = KeyManagerFactory.getInstance("SunX509");
        keyMgrFactory.init(keyStore, "<password>".toCharArray());

        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(keyMgrFactory.getKeyManagers(), null, null);
        SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

        SSLSocket sslSocket = (SSLSocket) sslSocketFactory.createSocket(host, port);
        String[] cipherSuites = sslSocket.getSupportedCipherSuites();
        sslSocket.setEnabledCipherSuites(cipherSuites);
        sslSocket.startHandshake();

        char[] t = token.toCharArray();
        byte[] b = Hex.decodeHex(t);

        OutputStream outputstream = sslSocket.getOutputStream();

        outputstream.write(0);
        outputstream.write(0);
        outputstream.write(32);
        outputstream.write(b);
        outputstream.write(0);
        outputstream.write(payload.length());
        outputstream.write(payload.getBytes());

        outputstream.flush();
        outputstream.close();

    } catch (Exception exception) {
        exception.printStackTrace();
    }
}

什么我还是好奇的是如何收到错误codeS。我用

What I'm still curious about is how to receive error codes. I tried it with

InputStream in = sslSocket.getInputStream(); 
[...]   

但没有成功。

的<一个href=\"https://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CommunicatingWIthAPS/CommunicatingWIthAPS.html\"相对=nofollow>苹果文档说，没有发生时没有错误没有答案发送，但是，从另一方面他们列出一个状态code表示没有遇到错误。

The Apple docs say that there is no answer send when no errors occured but on the other hand they list a status code for "No errors encountered".
