友盟U-Push推送与获取状态

Java中使用友盟消息推送

U-Push可以实现主动推送消息给App的终端用户，让用户实时实地的获取相关信息并拉活相应的app，那么如何在java中使用友盟U-Push 消息推送呢？

首先进入友盟官网去创建添加一个应用，以获取应用对应的Appkey和Umeng Message Secret。

然后进入开发者中心下载集成示例：

解压后，可以看到demo文件，以android广播推送为例,我们需要:

应用的appkey和appMasterSecret，DeviceToken 设备标识，Ticker 通知栏提示文字，Title 标题以及点击后显示的文字Text。

public void sendAndroidBroadcast() throws Exception {
        AndroidBroadcast broadcast = new AndroidBroadcast(appkey,appMasterSecret);
        broadcast.setTicker( "Android broadcast ticker");
        broadcast.setTitle(  "中文的title");
        broadcast.setText(   "Android broadcast text");
        broadcast.goAppAfterOpen();
        broadcast.setDisplayType(AndroidNotification.DisplayType.NOTIFICATION);
        // TODO Set 'production_mode' to 'false' if it's a test device. 
        // For how to register a test device, please see the developer doc.
        broadcast.setProductionMode();
        client.send(broadcast);
    }

那怎么在用户点击后显示图片等等附带数据呢？消息推送的有效期怎么设置？推送任务自动生成的id又怎么获取？

自定义接收类UmengResult

@Getter
@Setter
public class UmengResult {
        private String ret;
        private JSONObject data;
}

demo中,sendAndroidBroadcast（）

public void sendAndroidBroadcast() throws Exception {
        AndroidBroadcast broadcast = new AndroidBroadcast(appkey,appMasterSecret);
        broadcast.setTicker( "Android broadcast ticker");
        broadcast.setTitle(  "中文的title");
        broadcast.setText(   "Android broadcast text");
        broadcast.goAppAfterOpen();//默认点击消息拉活app
        broadcast.setDisplayType(AndroidNotification.DisplayType.NOTIFICATION);
        broadcast.setProductionMode();//生产模式，一开始改成测试避免手滑哦
        //可以使用setCustomField()给客户端推送附加数据
        JSONObject extraData = new JSONObject();
        extraData.put("img","imgUrl");
        extraData.put("source",new source());
        broadcast.setCustomField(extraData);
        //设置推送的有效期
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        Calendar c1 = Calendar.getInstance();
        Calendar c2 = Calendar.getInstance();
        c1.add(Calendar.MINUTE, 1);
        broadcast.setStartTime(sdf.format(c1.getTime()));
        // 友盟推送的有效期延迟一天
        c2.add(Calendar.DAY_OF_MONTH, 1);
        broadcast.setExpireTime(sdf.format(c2.getTime()));
        String result = client.send(broadcast);
         //获取推送消息的任务id
         UmengResult umengResult = JSON.parseObject(status.toString(), UmengResult.class);
         String taskid = umengResult.getData().get("task_id").toString();
    }

消息推送出去了，那怎么获取消息的状态，多少客户端收到推送消息，又有多少的点击量呢？

查阅api文档，可以看到获取任务状态的api为 '/api/status',需要以下参数

{
    "appkey":"xx",        // 必填, 应用唯一标识
    "timestamp":"xx",    // 必填, 时间戳，10位或者13位均可，时间戳有效期为10分钟
    "task_id":"xx"        // 必填, 消息发送时, 从返回消息中获取的task_id
}

打开pushClient.java,自定义我们获取状态的方法，代码如下：

protected static final String statusPath = "/api/status";

public String getPushStatus(String appkey,String task_id,String appMasterSecret) throws Exception {
    JSONObject getStatus = new JSONObject();
    getStatus.put("appkey", appkey);
    String timestamp = Integer.toString((int)(System.currentTimeMillis() / 1000));
    getStatus.put("timestamp", timestamp);
    getStatus.put("task_id",task_id);
    String url = host + statusPath;
    String postBody = getStatus.toString();
    String sign = DigestUtils.md5Hex(("POST" + url + postBody +                                           appMasterSecret).getBytes(StandardCharsets.UTF_8));
    url = url + "?sign=" + sign;
    HttpPost post = new HttpPost(url);
    post.setHeader("User-Agent", USER_AGENT);
    StringEntity se = new StringEntity(postBody, "UTF-8");
    post.setEntity(se);
    // Send the post request and get the response
    HttpResponse response = client.execute(post);
    System.out.println("Response Code : " + response.getStatusLine().getStatusCode());
    BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
    StringBuffer result = new StringBuffer();
    String line = "";
    while ((line = rd.readLine()) != null) {
        result.append(line);
    }
    return result.toString();
}

示例接口

    @RequestMapping(value = "/getStatus")
    public CommonResult GetStatus(@RequestBody MessageInfo model) throws Exception {
        PushClient pushClient = new PushClient();
        String s = pushClient.getPushStatus(model.getAppId(), model.getUmengTaskId(), model.getSecret());
        UmengResult umengResult = JSON.parseObject(s, UmengResult.class);
        //推送接收统计数目
        model.setSendCount((Integer) umengResult.getData().get("sent_count"));
        //推送打开统计数目
        model.setOpenCount((Integer) umengResult.getData().get("open_count"));
        //推送被忽略统计数目
        model.setDismissCount((Integer) umengResult.getData().get("dismiss_count"));
        messageInfoService.update(model);
        return processSuccess("更新成功");
    }

至此，U-Push的推送和获取后续状态的实例就完成了，单播，组播都可以用类似写法。
