javascript - How to send Push Notifications with Parse.com Cloudcode

Question

I want to send a Push Notification with Cloudcode on Parse.com.

The push notification should be sent to all android devices that are subscribed to a specific channel and trigger a service.

Answer 1

您所需要的只是一个安装查询以及随附的推送。例如：

var pushQuery = new Parse.Query(Parse.Installation);
pushQuery.containedIn("user", userlist);
Parse.Push.send({
  where: pushQuery, 
  data: {
     alert: "Your push message here!"
  }
}, {
  success: function() {
    response.success("pushed");
  }, error: function(error) {
   reponse.error("didn't push");
  }
});

该安装查询可以是基于通道的查询，并且您可以为推送查询制定其他规范，在文档中给出：

您无需查询即可向频道发送推送。只需调用Parse.Push.send并将通道数组添加到数据对象。

Parse.Push.send({
        channels: [ "channel_name" ],
        data: {
            alert: "Alert message"
        }
    }, {
        success: function () {
            response.success("Push was sent");
        },
        error: function (error) {
            response.error("Could not send push " + error)
        }
    });

确保不要在频道名称中使用空格和大写字母。该频道不会添加到后端订阅的频道中。

1) 添加

Parse.initialize("APPLICATION_ID", "JAVASCRIPT_KEY");

2) 在 Parse.com 中启用 Java 脚本推送通知

3）下载Java脚本项目“parse-js-blank”

4）使用Channel创建安装对象

5) 发送请求。

Parse.Push.send({
          channels: [ "Giants","Vaquar" ],
          data: {
            alert: "Vaquar Alert Message."
          }
        }, {
          success: function() {
            // Push was successful
          },
          error: function(error) {
            // Handle error
            alert("(error"+eval(error));
          }
        });
