之前一篇文章介绍了ios推送，使用php做客客户端，这里介绍java实现服务端，证书的配置以及IOS客户端的代码这里就不赘述了，主要介绍服务端证书的生成和推送的代码，java需要的证书实现方式，直接导出就可以了
输入密码导出文件push.p12
java的实现代码为：
public static void main(String[] args) {
try {
String deviceToken = "xxxxxxx";
//被推送的iphone应用程序标示符
PayLoad payLoad = new PayLoad();
payLoad.addAlert("测试我的push消息");
payLoad.addBadge(1);
payLoad.addSound("default");
PushNotificationManager pushManager = PushNotificationManager.getInstance();
pushManager.addDevice("iphone", deviceToken);
String host="gateway.sandbox.push.apple.com"; //测试用的苹果推送服务器
int port = 2195;
String certificatePath = "D:/push.p12"; //刚才在mac系统下导出的证书
String certificatePassword= "123456";
pushManager.initializeConnection(host, port, certificatePath,certificatePassword, SSLConnectionHelper.KEYSTORE_TYPE_PKCS12);
//Send Push
Device client = pushManager.getDevice("iphone");
pushManager.sendNotification(client, payLoad); //推送消息
pushManager.stopConnection();
pushManager.removeDevice("iphone");
}
catch (Exception e) {
e.printStackTrace();
System.out.println("push faild!");
return;
}
System.out.println("push succeed!");
}
需要用到的jar包
bcprov-jdk16-145-1.jar
commons-io-2.0.1.jar
commons-lang-2.5.jar
javapns-jdk16-163.jar 见附件，其他的都很容易下载
log4j-1.2.16.jar
--------------------------------------------------------------
以上用到的是开源项目javapns的推送方式，还有另外一种方式
public static void main(String[] args) {
String keyPath = "/Users/allen/Desktop/push.p12";
String ksType = "PKCS12";
String ksPassword = "123456";
String ksAlgorithm = "SunX509";
String deviceToken = "cd265a77f1b4421e10902b2d3422d6b47bcdc0e96de836d89b86c6c2037a571d";
String serverHost = "gateway.sandbox.push.apple.com";
int serverPort = 2195;
try {
InputStream certInput = new FileInputStream(keyPath);
KeyStore keyStore = KeyStore.getInstance(ksType);
keyStore.load(certInput, ksPassword.toCharArray());
KeyManagerFactory kmf = KeyManagerFactory.getInstance(ksAlgorithm);
kmf.init(keyStore, ksPassword.toCharArray());
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(kmf.getKeyManagers(), null, null);
SSLSocketFactory socketFactory = sslContext.getSocketFactory();
Socket socket = socketFactory.createSocket(serverHost, serverPort);
StringBuilder content = new StringBuilder();
String text = "this is a test.";
content.append("{\"aps\":");
content.append("{\"alert\":\"").append(text)
.append("\",\"badge\":1,\"sound\":\"")
.append("ping1").append("\"}");
content.append(",\"cpn\":{\"t0\":")
.append(System.currentTimeMillis()).append("}");
content.append("}");
byte[] msgByte = makebyte((byte)1, deviceToken, content.toString(), 10000001);
System.out.println(msgByte);
socket.getOutputStream().write(msgByte);
socket.getOutputStream().flush();
socket.close();
} catch (Exception e) {
e.printStackTrace();
}
}
