javascript - 解析发送给 0 个收件人的推送通知

Question

我正在尝试让我的应用程序向个人用户发送推送通知(用户之前已经注册过)。我试图做的目的是通知用户他们之前在我的商店下的订单已经发货。

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
NSString *loggedUser = [userDefaults stringForKey:@"loggedUser"];

PFInstallation *installation = [PFInstallation currentInstallation];
[installation addUniqueObject:loggedUser forKey:@"channels"];
[installation saveInBackground];

(我没有使用 PFUser 而是有一个变量 loggedUser 可以正常工作。)

上面的代码似乎工作正常，因为如果我去 Parse 上的数据浏览器，我可以在安装表 channel 列上看到用户名。

但是，虽然我在云代码上看到了用户，这意味着我在发送推送通知时已成功上传，但我看到它已发送给 0 个收件人。

使用以下代码通过 JavaScript 发送推送:

(变量 user 如上所述，我确保它也能正常工作。)

Parse.Push.send({
    channels: "[\""+user+"\"]",
    data: {
        alert: "Your order has been shipped."
    }
}, {
    success: function() {
        alert('The push notification has been sent correctly')
    },
    error: function(error) {
        alert('Error: '+ error)
    }
});

有人知道我在做什么错吗？是吗 channels:写错了吗？或者是因为我不能在这个 Parse 发送操作中使用变量？

我要做的第一件事是更改您在 Parse.Push.send() 中发送 channel 的方式

channels: [user],

假设 user是匹配 loggedUser 的字符串从前面的代码。
