极光推送服务端向手机app即时推送消息或通知
以前一直在做后台开发，对消息的推送很感兴趣，正好项目中要用到极光推送，今天抽空来记录下这两天的研究成果。
我们知道IOS有自己的推送服务，但很遗憾Android没有原生的推送服务，现在有很多第三方的推送服务，比如个推、极光、亚马逊、百度云、聚能等。今天我们就来研究下极光推送的后台服务器如何实现。
关键点：
1.首先最好是把极光官网java后台服务器的demo下载下来，里面有我们需要的jar包，以及example.
2.极光推送的关键jpushClient = new JPushClient(masterSecret, appKey, 3);就是这个类。其中的参数需要我们从极光官网注册开发者，然后创建具体项目获取相应的两个key值。其中appKey值就是我们手机端对应的key值
3.极光推送给我们提供了很多种推送的方式，我们可以选择某一个平台进行推送（Android ,IOS ,Windows Phone），也可以全部推送；我们可以针对某个特别的用户进行推送（设置alisa），也可以针对特别的群体进行推送（设置tag），第三个参数是设置推送保留的时间，只要在有效时间内上线就可以收到推送信息
4. 极光推送现在都用https连接，提交请求是post，获取数据为get
// 对android和ios设备发送
JPushClient jpush =
new
JPushClient(masterSecret, appKey);
// 对android和ios设备发送,同时指定离线消息保存时间
JPushClient jpush =
new
JPushClient(masterSecret, appKey, timeToLive);
// 指定某种设备发送
JPushClient jpush =
new
JPushClient(masterSecret, appKey, DeviceEnum.Android);
// 指定某种设备发送，并且指定离线消息保存时间
JPushClient jpush = new
JPushClient(masterSecret, appKey, timeToLive, DeviceEnum.IOS);
