Discord.js-已发送消息的计数器，DM到公会的所有成员

Question

因此，我有一个有效的代码示例，该示例将DM发送给行会的所有成员。 但是，我希望整个过程以一条消息结尾，例如：“成功发送XX条消息”。

        const sentMessages = 0;
        if (!message.member.hasPermission(`ADMINISTRATOR`)) {
            message.channel.send(`You don't have permission to use this command!`);
            message.client.channels.cache.get(logchannel).send(`${message.author} tried using DMALL! ` + dato.toLocaleTimeString() + dato.toLocaleDateString());
            return;
        } else {
            const delay = (msec) => new Promise((resolve) => setTimeout(resolve, msec));
            const sendMessage = args.join(" ");
            message.channel.send(`Sending messages, please wait...`);
            await delay(1000);
            let interval = 500; // how much time should the delay between two iterations be (in milliseconds)?
            let promise = Promise.resolve();
            message.guild.members.cache.forEach(function (user) {
                promise = promise.then(function () {
                    if (user.id != message.client.user.id) {
                        user.send(sendMessage);
                        sentMessages++;
                        return new Promise(function (resolve) {
                            setTimeout(resolve, interval);
                        });
                    }
                });
                message.channel.send(`Successfully sent ${sentMessages} messages!`);
            });

无论何时何地放置，结尾的消息（成功...）始终返回0。 如果我在 sentMessages ++ 下面放一个这样的行： message.channel.send（`Sent：$ {sentMessages}）; ； 我会得到一个期望的递增数字。

我在哪里做错什么？

最终找到了一个比我更擅长编码的朋友。 他想出了一种完全不同的到达目的地的方式：

        if (!message.member.hasPermission(`ADMINISTRATOR`)) {
            message.channel.send(`You don't have permission to use this command!`);
            message.client.channels.cache.get(logchannel).send(`${message.author} tried using DMALL in **${message.guild.name}**!` + dato.toLocaleTimeString() + dato.toLocaleDateString());
            return;
        } else {
            const delay = (msec) => new Promise((resolve) => setTimeout(resolve, msec));
            const sendMessage = args.join(" ");
            message.channel.send(`Sending messages, please wait...`);
            await delay(1000);
            const interval = 500;
            let array;
            try {
                const all = await message.guild.members.fetch();
                array = all.array();
            } catch {
                array = message.guild.members.cache.array();
            }
            let sentMessages = 0;
            for (var i = 0; i < array.length; i++) {
                const user = array[i];
                if (!user.bot) {
                    try {
                        await user.send(sendMessage);
                        sentMessages++;
                        await delay(interval);
                    } catch { }
                }
            }
            message.client.channels.cache.get(logchannel).send(`${message.author} sent a DM to all members of: **${message.guild.name}**!` + dato.toLocaleTimeString() + dato.toLocaleDateString());
            message.channel.send(`Finished sending messages to all users, ${sentMessages} messages sent!`);
        }

此代码经过测试，发现可以正常工作

使用let sentMessages = 0代替const sentMessages = 0

常量无法更新或重新分配，因此sentMessages++不会做任何事情

如果您不想成为Discord的禁令，请不要这样做，禁止将私人消息发送给行会的所有成员。
