在中讲述了消息推送的原理及实现总结，但并未讲到Provider服务端及Client App客户端的实现，但我在这里只是简单讲述Provider服务端（JAVA实现）步骤如下：
一、 制作Provider服务端所需要的*.p12文件：
在的图2-8中所展示的密钥、证书，我们并没有使用到它，那么为什么要展示出来呢，猜猜是为什么？为制作*.p12文件？哈哈，您猜对了，下面我们就利用它来制作*.p12文件，步骤：（[MacBookà应用程序à实用工具à钥匙串访问[钥匙串：登录,种类：证书]à选择刚刚生成的证书(Apple Development IOS Services:*******)à菜单à文件à导出项目…à[存储为：任意文件名(如：iPush),文件格式：默认（个人信息交换(.p12)）]à输入密码以进行导出[密码：任意，验证：与密码同一]à输入MACBook登录密码à允许à最终生成。 关键步骤如图1-1
1-1
二、 编写Client App客户端的关键代码，如下：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen]bounds]] autorelease];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
//消息推送支持的类型
UIRemoteNotificationType types =
(UIRemoteNotificationTypeBadge
|UIRemoteNotificationTypeSound
|UIRemoteNotificationTypeAlert);
//注册消息推送
[[UIApplication sharedApplication]registerForRemoteNotificationTypes:types];
return YES;
}
//获取DeviceToken成功
- (void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
NSLog(@"DeviceToken: {%@}",deviceToken);
//这里进行的操作，是将Device Token发送到服务端
}
//注册消息推送失败
- (void)application:(UIApplication *)application
didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
NSLog(@"Register Remote Notifications error:{%@}",[errorlocalizedDescription]);
}
//处理收到的消息推送
- (void)application:(UIApplication *)application
didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NSLog(@"Receive remote notification : %@",userInfo);
UIAlertView *alert =
[[UIAlertView alloc] initWithTitle:@"温馨提示"
message:@"推送成功！"
delegate:nil
cancelButtonTitle:@"确定"
otherButtonTitles:nil];
[alert show];
[alert release];
}
三、编写Provider服务端关键代码，如下：
import javapns.back.PushNotificationManager;
import javapns.back.SSLConnectionHelper;
import javapns.data.Device;
import javapns.data.PayLoad;
public class MainSend
{
public static void main(String[] args) throws Exception
{
try
{
//从客户端获取的deviceToken
String deviceToken = "3a20764942e9cb4c4f6249274f12891946bed26131b686b8aa95322faff0ad46";
System.out.println("Push Start deviceToken:" + deviceToken);
//定义消息模式
PayLoad payLoad = new PayLoad();
payLoad.addAlert("消息推送测试！");
payLoad.addBadge(4);
payLoad.addSound("default");
//注册deviceToken
PushNotificationManager pushManager = PushNotificationManager.getInstance();
pushManager.addDevice("iPhone", deviceToken);
//连接APNS
String host = "gateway.sandbox.push.apple.com";
int port = 2195;
String path = "/Users/iMilo/Work.localized/iShop/project/service/iPush/";
String certificatePath = (path + "src/ipush/iPush.p12");
//certificatePath 步骤一中生成的*.p12文件位置
String certificatePassword = "Love24mm";
pushManager.initializeConnection(host, port, certificatePath, certificatePassword, SSLConnectionHelper.KEYSTORE_TYPE_PKCS12);
//发送推送
Device client = pushManager.getDevice("iPhone");
pushManager.sendNotification(client, payLoad);
//停止连接APNS
pushManager.stopConnection();
//删除deviceToken
pushManager.removeDevice("iPhone");
System.out.println("Push End");
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
}
注意：如果Provider服务端为Objective-C实现的话，就不需要*.p12证书。下面给出网上的相应demo地址：
