javascript - 批量删除如何工作？

Question

我试图bulkDelete让我的机器人删除它的消息，但我收到了这个错误：

(node:5724) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Bad Request
(node:5724) DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

这是我的代码：

const Discord = require('discord.js');
const bot = new Discord.Client();
const config = require("./config.json");

bot.on('ready', () =>{
    console.log('I am ready!');
});

//var cleanarr=[];

bot.on("message", message =>{
    if (message.author.bot) return;
var cleanarr=[];
        let command = message.content.split(" ")[0];
command = command.slice(config.prefix.length);

        let args = message.content.split(" ").slice(1);
if (message.content == 'lol'){
    message.channel.sendMessage('LUL');
    cleanarr.unshift(`${message.channel.lastMessageID}`);
    }
if (command == "clean") {
    message.channel.sendMessage('Cleaning...');
    message.channel.bulkDelete(cleanarr);
    var cleanarr = [];

bulkDelete 需要什么？是消息ID还是其他？

我不知道我这样做是否正确（显然我不是），因为我开始编码时对 javascript 或任何相关知识的了解为零。

从通道中删除x消息的最简单方法是提供一个整数 from2 - 100作为<TextChannel>.bulkDelete方法的参数。

例子：

message.channel.bulkDelete(100).then(() => {
  message.channel.send("Deleted 100 messages.").then(msg => msg.delete(3000));
});

discord 批量删除端点需要您要删除的消息数组。昨天这里的小注意，批量删除端点不会删除超过 2 周的消息。

这是更新的一个；

    }else if (command === 'purge') {
    const amount = parseInt(args[0]);

    if (isNaN(amount)) {
        return message.reply('that doesn\'t seem to be a valid number.');
    }

    if (isNaN(amount)) {
    return message.reply('You have enterd a invalid amount. Try ``purge 5``');
} else if (amount < 2 || amount > 100) {
    return message.reply('you need to input a number between 2 and 100.');
}
message.channel.bulkDelete(amount);
message.channel.send(amount + ' ' +'messages deleted');

    }
});
