基于javapns的IOS推送的配置

1.开启push log

javapns使用的log4j，为确保log的正常工作，在使用过程中添加如下代码：

import org.apache.log4j.*;
   ...
try {        
 BasicConfigurator.configure();  
    ... 
 } catch (Exception e) { 
 //do sth.
 }

log4j.properties中添加：

log4j.logger.javapns=debug

2.sandbox(开发环境)到production(产品环境)迁移的注意事项

两套环境的device tokens是不同的，在迁移后需要更新device tokens。

两套环境的certificates也是不同的，需要更新证书。

修复sandbox环境工作，production推送失败的解决方案。http://www.techjini.com/blog/how-we-fixed-production-push-notifications-not-working-while-sandbox-works/

3.定制消息内容

public void send (List<Device> devices, Object keystore, String password, boolean production) {  
      /* Build a blank payload to customize */       
     PushNotificationPayload payload = PushNotificationPayload.complex();  
      /* Customize the payload */        
     payload.addAlert("Hello World!");  //apple提示消息      
     payload.addCustomDictionary("webview", "http://www.womai.com"); //隐藏参数，用于实现一些定制操作，比如自动跳转。   
     payload.addCustomDictionary("mykey2", 2);     // etc.  
      /* Push your custom payload */        
     List<PushedNotification> notifications = Push.payload(payload, keystore, password, production, devices);  
}

 

4.多线程批量发送推送消息

public void send (List<Device> devices, Object keystore, String password, boolean production) {  
      /* Prepare a simple payload to push */        
PushNotificationPayload payload = PushNotificationPayload.alert("Hello World!");  
      /* Decide how many threads you want to create and use */         
int threads = 30;  
      /* Start threads, wait for them, and get a list of all pushed notifications */         
List<PushedNotification> notifications = Push.payload(payload, keystore, password, production, threads, devices);  
}

 

 备注:以上多线程方法在所有线程执行完后返回，如果不想等线程执行完毕，可以通过在内部创建一个单独的线程：

 (示例： new Thread() {public void run() {...}}.start();). 

 

5.创建消息队列(连接池)

一个队列就是一组连接APNS的多线程连接，队列会动态将消息分发到不同的线程中去。 

public void send (String token, Object keystore, String password, boolean production) {  
      /* Prepare a simple payload to push */        
PushNotificationPayload payload = PushNotificationPayload.alert("Hello World!");  
      /* Decide how many threads you want your queue to use */        
int threads = 30;  
      /* Create the queue */         
PushQueue queue = Push.queue(keystore, password, production, threads);  
      /* Start the queue (all threads and connections and initiated) */         
queue.start();  
      /* Add a notification for the queue to push */         
queue.add(payload, token);  
}

  备注:如果不通过queue.start消息队列，队列会在第一次调用queue.add 的时候启动

 

5.建议开启EnhancedNotificationFormat

  默认为开启状态，建议开启,开启后可以通过Payload对象获取到更多推送消息的详细信息，例如执行状态，失效时间等。

 

6.推送状态(错误)管理

1)error-response packets 

    pushedNotification.isSuccessful() //判断是否推送成功 

    pushedNotification.getException() //获取详细错误信息，系统中错误不会抛出，以保证多线程的正常运作,错误信息会记录到pushedNotification中。   

示例代码：

    List<PushedNotification> notifications = Push.alert("Hello World!",                                                          "keystore.p12", "keystore_password", false, devices);                          for (PushedNotification notification : notifications) {                                 if (notification.isSuccessful()) {                                         /* Apple accepted the notification and should deliver it */                                           System.out.println("Push notification sent successfully to: " +                                          notification.getDevice().getToken());                                         /* Still need to query the Feedback Service regularly */                                   } else {                                         String invalidToken = notification.getDevice().getToken();                                         /* Add code here to remove invalidToken from your database */                                           /* Find out more about what the problem was */                                           Exception theProblem = notification.getException();                                         theProblem.printStackTrace();                                         /* If the problem was an error-response packet returned by Apple, get it                                          ResponsePacket theErrorResponse = notification.getResponse();                                         if (theErrorResponse != null) {                                                 System.out.println(theErrorResponse.getMessage());                                         }                                 }                         }  

2)Feedback Service

 public class FeedbackTest {  

      public static void main(String[] args) {         

                List<Device> inactiveDevices = Push.feedback("keystore.p12", "keystore_password", false);                 /* remove inactive devices from your own list of devices */

    }

备注：Sandbox Feedback Service not listing device after app is removed

     Delays involving the Feedback service
