Discord.js：机器人看不到消息

Question

我一直在研究快速数学命令，它的工作原理是这样的：我执行它，它在聊天中发送一个问题，发送正确答案的人获胜。

但是如你所见，它没有看到我的 46 消息，忽略它，并在 30 秒后发送“无人接听！”

我的代码是：

const { MessageEmbed } = require('discord.js');
const Discord = require("discord.js")

module.exports = {
  name: "game",
  description: "smth",
  aliases: ["gamestart", "startgame"],
  permissions: ["MANAGE_MESSAGES"],
  timeout: 10000,
execute: async (client, message, args) => {
    var a = Math.floor(Math.random() * 50) + 1
    var b = Math.floor(Math.random() * 50) + 1
    var ab = await a + b
    console.log(ab)
    let embed = new MessageEmbed()
    .setTitle(":chart_with_downwards_trend: Quick Math")
    .setDescription(`Solve the problem below and get XP.\n\n\`${a}\` + \`${b}\` = **???**`)
    .setFooter("123")

    const msg = await message.channel.send(embed)

    try {
      let filter = (m) => {
        if (m.author.bot) return;
        if (m.channel.id == msg.channel.id && m.content === ab) return true;
        else {
          return false;
        }
      };
      let res = await msg.channel.awaitMessages(filter, {
        time: 30000,
        errors: ["time"],
      });
      if (res) {
        let embed = new MessageEmbed()
        .setTitle(":chart_with_downwards_trend: Quick Math")
        .setDescription(`The correct answer was \`${ab}\`\n\nThe winner is **you**!`)
        .setFooter("123")
        msg.channel.send(embed)
      }
    } catch (err) {
      console.log(err)
      msg.channel.send(
        "No one answered!"
      );
    }
}
}

控制台没有报错，看起来像这样： 46

这真的很奇怪，我请求你的帮助。提前致谢。

更新：（将 === 更改为 == 之后）

控制台日志：

确保在 30000 毫秒后记录 Collection [Map] {} 部分。

猜猜问题出在这一行：

if (m.channel.id == msg.channel.id && m.content === ab) return true;

您正在搜索的消息的内容（当然是字符串）严格等于您之前计算的结果（数字）并且=== 不仅检查变量的内容，它还会检查还有变量的类型，所以：'46' === 46 将返回 false。 你可以做的是：

• 使用double equals operator（不推荐）=>'46' == 46 返回真
• 解析Number中的传入消息=>Number('46') === 46返回true

此外，我更喜欢使用消息的cleanContent 属性，以确保仅检索消息的有效内容而不更改它。 希望对您有所帮助：D

编辑： 刚刚看到您导入了两次 discord.js 库，而不是这样做，您只需从 Discord 模块中提取 MessageEmbed：

const Discord = require('discord.js');
const { MessageEmbed } = Discord;
