Java 每次推送获取多个通知

当我发送推送通知时，设备上会出现5个相同的通知。有什么原因吗？以下是我的application.java和清单：

公共类应用程序扩展了android.app.Application{

public Application() {
}

@Override
public void onCreate() {
    super.onCreate();
    Parse.setLogLevel(Parse.LOG_LEVEL_VERBOSE);

    // Initialize the Parse SDK.
    Parse.initialize(this, "__REMOVED KEY FOR SECURITY___", "__REMOVED KEY FOR SECURITY___");


    // Specify an Activity to handle all pushes by default.

    PushService.setDefaultPushCallback(this, SplashActivity.class);
    ParseInstallation.getCurrentInstallation().saveInBackground();
}

登录parse.com，转到您的仪表板，检查数据浏览器，在那里您将看到parse安装类的表和数据。似乎您的parse安装表中有相同设备令牌的重复行。您可以运行cron作业来删除重复项，并且只保留上次更新的一个

原因：

这是因为每次在（相同）设备上安装应用程序时，parse都会在“Installation”类中创建一条新记录，因此deviceToken会被复制

解决方案：

您可以通过查找重复条目来解决此问题，并避免在“Installation”类的“beforeSave”函数中插入。最好用javascript编写此部分，然后转到CloudCode。因此，可以减少客户端（android）设备与服务器之间的通信

Parse.Cloud.beforeSave(Parse.Installation, function(request, response) {
    if(!request.object.isNew()) {                       // Old Obj - Updating
        response.success();
    } else {                                            // New Obj - Inserting
        Parse.Cloud.useMasterKey();
        var query = new Parse.Query(Parse.Installation);
        query.equalTo("deviceToken", request.object.get("deviceToken"));
        query.first().then(function(duplicate) {
            if (typeof duplicate === "undefined") {
                console.log("New installation ..");
                response.success();
            } else {
                console.log("Duplicate exist ..");
                response.error();          
            }
        }, function(error) {
            console.warn(error.code + error.message);
            response.error();
        });
    }
});

您可以使用“deviceToken”或自定义字段（如“userID”）来检查重复项，或者根据需要同时使用这两个字段

更新： 在上面的代码中，我刚刚避免了重复条目，但是删除现有条目并插入新条目（如下所示）是一种很好的做法

我也遇到了同样的问题。问题是，当我调用云函数时，“params”参数为null。当我为其设置值时，问题得到了解决。

检查数据浏览器上的安装类，看看是否存在相同的多个设备令牌，以及如何实现这一点@johngomez@epicfinley登录parse.com，转到您的仪表板，并检查数据浏览器，在那里您将看到Parse安装类的表和数据。似乎您的Parse安装表中有相同设备令牌的重复行。您可以运行cron作业删除重复行，并仅保留最后更新的OneHanks@thiyagab将其作为答案发布，我将接受它。@phreakhead您可以在保存之前保存云代码，您可以在其中检查数据是否存在，然后允许添加或跳过我认为此代码将删除更新的安装，而不是旧的安装。是@iturki。正如我在回答中已经提到的，我只是避免了重复插入（新的）。但最好的做法是删除现有的，然后插入新的。Cron Job！！Parse没有Cron jobs。@iturki我指的是后台作业，请参阅此处。问题不在于如何在数据中运行查询。问题在于如何识别数据中的重复项。数据中可能有多行，但不同的开发人员iceTokens，指向同一物理设备。@iturki是的，我们有一种方法可以使用规范ID来处理这个问题，您将如何使用规范ID进行解析？
