极光推送 使用实例 (一)服务端
最近一直在做后台开发,但心里还是总惦记着Android,感觉还是Android有意思。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
ok 接下来就看服务端的实现(JAVA),JdPush推送方法+一个Servlet

可以看到上面我们推送平台设置的是所有平台,Audience设置为all(所有用户),这里key值和masterSecret值放在servlet中了。
servlet很简单,只要传入两个key值,调用该方法就可以
- package com.weiwend.jdpush.servlet;
- import java.io.IOException;
- import javax.servlet.ServletException;
- import javax.servlet.http.HttpServlet;
- import javax.servlet.http.HttpServletRequest;
- import javax.servlet.http.HttpServletResponse;
- import com.sun.org.apache.xml.internal.serializer.utils.Utils;
- import com.weiwend.jdpush.Jdpush;
- import com.weiwend.jdpush.utils.Base64Utils;
- /**
- * Servlet implementation class tuisong
- */
- public class tuisong extends HttpServlet {
- private static final long serialVersionUID = 1L;
- private static final String appKey ="84cf5ee2099c654aa03a5d70";
- private static final String masterSecret = "7cf23f25a41806d5fd29e3c5";
- public tuisong() {
- super();
- // TODO Auto-generated constructor stub
- }
- /**
- * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
- */
- protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
- Jdpush.testSendPush(appKey,masterSecret);
- System.out.println("sucess");
- }
- /**
- * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
- */
- protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
- // TODO Auto-generated method stub
- }
- }
最后来看下运行的结果,可以看到,提交数据是以json格式。如果返回{"msg_id":1663001319,"sendno":1981162191}这样数据说明推送已经成功发送
- {"platform":"all","audience":"all","notification":{"alert":"祝大家新春快乐"},"options":{"sendno":1981162191,"apns_production":false}}
- {"msg_id":1663001319,"sendno":1981162191}................................
- sucess
源码分析:
JPushClient jpushClient = new JPushClient(masterSecret, appKey, 3);实际上是实例化了一下三个类
- public JPushClient(String masterSecret, String appKey, int maxRetryTimes) {
- _pushClient = new PushClient(masterSecret, appKey, maxRetryTimes);
- _reportClient = new ReportClient(masterSecret, appKey, maxRetryTimes);
- _deviceClient = new DeviceClient(masterSecret, appKey, maxRetryTimes);
- }
PushPayload payload = buildPushObject_all_all_alert();,PushPayload类里包含了传递和返回的所有数据
- public class PushPayload implements PushModel {
- private static final String PLATFORM = "platform";
- private static final String AUDIENCE = "audience";
- private static final String NOTIFICATION = "notification";
- private static final String MESSAGE = "message";
- private static final String OPTIONS = "options";
- private static final int MAX_GLOBAL_ENTITY_LENGTH = 1200; // Definition acording to JPush Docs
- private static final int MAX_IOS_PAYLOAD_LENGTH = 220; // Definition acording to JPush Docs
- private static Gson _gson = new Gson();
- private final Platform platform;
- private final Audience audience;
- private final Notification notification;
- private final Message message;
- private Options options;
- private PushPayload(Platform platform, Audience audience,
- Notification notification, Message message, Options options) {
- this.platform = platform;
- this.audience = audience;
- this.notification = notification;
- this.message = message;
- this.options = options;
- }
PushResult result = jpushClient.sendPush(payload);可以看到就是sendPost方法,然后接受返回的数据
- public PushResult sendPush(PushPayload pushPayload) throws APIConnectionException, APIRequestException {
- Preconditions.checkArgument(! (null == pushPayload), "pushPayload should not be null");
- if (_globalSettingEnabled) {
- pushPayload.resetOptionsTimeToLive(_timeToLive);
- pushPayload.resetOptionsApnsProduction(_apnsProduction);
- }
- ResponseWrapper response = _httpClient.sendPost(_baseUrl + PUSH_PATH, pushPayload.toString());
- return BaseResult.fromResponse(response, PushResult.class);
- }
另外我专门找了下sendNo如何生成的,其实就是随机生成的一个数字
- public static Options sendno() {
- return newBuilder().setSendno(ServiceHelper.generateSendno()).build();
- }
- public static int generateSendno() {
- return RANDOM.nextInt((MAX - MIN) + 1) + MIN;
- }
大家有兴趣也可以详细看一下代码的实现.
