NodeJS和MongoDB的模式结构建议

问题出在代码中

let count = 0;
tokens.forEach(function (to) {
    let message = {
        to: to,
        notification: {
            title: varConst.APP_NAME,
            body: notification
        },
        data: payload
    };

    fcmWeb.send(message, function (err, response) {
        if (err) {
            console.log("Something has gone wrong!");
        } else {
            console.log("Successfully sent with response: ", response);
        }

        count++;
        if (count == tokens.length) {
            callback("Send All");
        }
    });
});

在上面的代码块中,不用使用forEach,只需给出注册id的数组,fcm将处理其余的部分。

let message = {
    registration_ids:["eJ8-S5jddyI:APA91bG1jmJBVEtB04","eJ8-S5jddyI:APA91bG1jmJBVEtB04"],
    notification: {
        title: varConst.APP_NAME,
        body: notification
    },
    data: payload
};
