解析云代码 - 添加到阵列

标签： javascript parse-platform cloud parse-server

使用我的云代码尝试了不同变化的负载，但我无法使其工作。基本上我有一个推送通知功能，在这个功能中我想要一个对象添加到PFUser的阵列，但是你不能在Xcode中使用一个主密钥，所以这里有＃s我有什么：

Xcode云功能我提供了正确的信息，功能到底......只是函数没有因某种原因设置通知

答案 0 :(得分：0)

我最终弄清楚了这篇文章的答案。这不起作用的原因是因为我需要首先在单独的查询中获取用户对象，然后使用主密钥保存它。我还发现，有一个函数可以将数据附加到现有数组而无需创建另一个数据（parseObject.add（））：

var userQ   =   new Parse.Query(Parse.User);
userQ.get(userid, {
    success: function(theuser) {
        console.log("### got userrrrrrrrrr!");
        theuser.add("notifications", n_object);
        theuser.save(null, {useMasterKey:true});
    },
    error: function(object, error) {
        // The object was not retrieved successfully.
        // error is a Parse.Error with an error code and message.
    }
});

这组代码在之前执行：

response.success('success. end of iospush');
