通过 Java 与 Apple Push Notification Server 进行 SSL 握手 [英] SSL handshake with Apple Push Notification Server via Java
问题描述
您好,我正在尝试使用 Java 向我的设备发送推送消息.但是在建立 ssl 连接时我已经遇到问题了.这是到目前为止的代码:
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:
java.io.IOException: failed to decrypt safe contents entry: javax.crypto.BadPaddingException: Given final block not properly padded
我猜 apns-dev-key.p12 文件有问题.有什么提示吗?
I guess there is some problem with the apns-dev-key.p12 file. Any hints?

推荐答案
这是我的工作示例:
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();
}
}
我仍然好奇的是如何接收错误代码.我试过了
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.
Apple 文档说没有发生错误时没有应答发送,但另一方面,它们列出了未遇到错误"的状态代码.
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".
