1.jpushClient.sendPush（pushpayLoad）：是发送推送的主要方法

2.pushpayload是具体推送消息、推送对象范围的封装

3.jpushClient.sendPush()的返回值是pushResult,pushResult封装了返回相关的具体信息，包括messageID

4.pushpayload的构造方法为静态方法，

pushpayload = PushPayload.newBuilder()                      .setAudience(Audience.alias(alias))                      .setPlatform(Platform.all())                      .setMessage(Message.content(content)).build();

5.获得推送消息的mid：long messigeID = pushResult.msg_id;//静态方法

6.查询推送消息的成功数：

通过receivedResult。receivedResult的获取方法是通过mid获得,jpushClient.getReportReceiveds(mid); 

jpushClient = new JPushClient(MASTERSECRET, APPKEY, Integer.valueOf(DAY));          PushPayload payload = null;          try {              ReceivedsResult result = jpushClient.getReportReceiveds(mid);              Received received = result.received_list.get(0);              System.out.println("android_received:" + received.android_received                      + "\nios:" + received.ios_apns_sent);              log.debug("Got result - " + result);
