apicloud是一款用html5封裝的手機端的一個東西，訊息推送就是我們經常說的手機開啟一個軟體後，該軟體會出現相應的訊息顯示在通知欄，例如這樣

怎麼才能實現呢，其實完成下面幾步就ok了

1、在極光推送網站（ https://www.jpush.cn ）註冊帳號，並建立應用，獲取APP_KEY

2、在應用的config.xml下寫下

<?xml version="1.0" encoding="UTF-8"?>

<widget id="A6903547912689" version="0.0.1">
  <name>helloworld</name>
  <description>世界你好</description>
  <author email="
 
[email protected]" href="http://www.apicloud.com">SK1995</author>
  <content src="indexdemo.html"/>
  <preference name="appBackground" value="rgba(0,0,0,0)"/>
  <preference name="windowBackground" value="rgba(0,0,0,0)"/>
  <preference name="frameBackgroundColor" value="rgba(0,0,0,0)"/>
  <preference name="autoLaunch" value="true"/>
  <preference name="autoUpdate" value="true"/>
  <preference name="smartUpdate" value="false"/>
  <preference name="debug" value="true"/>
  <preference name="statusBarAppearance" value="true"/>
  <permission name="location"/>
  <permission name="internet"/>
  <access origin="*"/>
  <feature name="ajpush">
    <param name="app_key" value="15d39c8316d86519244de74f"/>
    <param name="channel" value="17d3ea252e685d947a2911ac"/>
  </feature>
</widget>
 

示例如下：

<feature name="ajpush">
        <param name="app_key" value="123456789" />
        <param name="channel" value="your channel" />
    </feature>

1. app_key：通過極光推送網站獲得
2. channel: 渠道號

渠道號隨便寫，沒有關係

然後在頁面加入啟動就自動執行的方法，加上初始化和監聽

function test() {
				var ajpush = api.require('ajpush');
				var param = {
					alias : 'myalias',
					tags : ['tag1', 'tag2']
				};
				ajpush.bindAliasAndTags(param, function(ret) {
					var statusCode = ret.statusCode;
				});
				ajpush.init(function(ret) {
					if (ret && ret.status) {
						//success
						ajpush.setListener(function(ret) {
							var id = ret.id;
							var title = ret.title;
							var content = ret.content;
							var extra = ret.extra;
							console.log("id=" + id + ",title=" + title + ",content=" + content + ",extra=" + extra);
						});
					}
				});
			}
 

Java中程式碼這麼寫，appkey依然是極光的appkey

package qh.zcy.test;

	 static {
		 jPushClient =new JPushClient(masterSecret, appKey);
		 //PushPayload payload = buildPushObject_all_all_alert();
	 }
	 
	
	 public static PushPayload buildPushObject_all_all_alert(){
		return PushPayload.newBuilder().setPlatform(Platform.android()).setAudience(Audience.tag("tag1")).setNotification(Notification.android("樂吧一日遊", "title", null)).build();
	 }
}

@RequestMapping("/push")  
    public static String push(HttpServletResponse response) throws APIConnectionException, APIRequestException{  
		PushPayload payload = Jiguang.buildPushObject_all_all_alert();
		PushResult result = Jiguang.jPushClient.sendPush(payload);
		response.setContentType("text/html");  
        response.setCharacterEncoding("utf-8");  
        PrintWriter out=null;  
        try {  
            Map<String, String> maps=new HashMap<String, String>();
            maps.put("name", "推送成功");
            
            JSONArray array=JSONArray.fromObject(maps);
           // JSONObject obj = JSONObject.fromObject(app);
            out=response.getWriter();  
            out.print(array);
            
        } catch (IOException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }finally{
        	out.close();
        }
		return null;
    }
