Question

我正在尝试制作 Karuta 交易应用程序机器人，但它一直在说 Cannot read property “send” of undefined。

每次我试图找出问题时，它都会变得越来越糟。

有人可以帮我找出这个破坏我申请流程的问题吗？

尝试发送到名为 test 的通道时失败

代码：

const { Client, Message, MessageEmbed } = require('discord.js');

module.exports = {
    name: `apply`,
    /**
     * @param {Client} client 
     * @param {Message} message 
     * @param {String[]} args 
     */
    async execute(client, message, args) {
        const questions = [
            "Would you like to advertise your Karuta Card Trades?",
            "Cards FS:",
            "Cards FB:"
        ]
        let collectCounter = 0;
        let endCounter = 0;

        const filter = (m) => m.author.id === message.author.id;
        
        const appStart = await message.author.send(questions[collectCounter++]);
        const channel = appStart.channel

        const collector = channel.createMessageCollector(filter);
        
        collector.on("collect", () => {
            if(collectCounter < questions.length) {
                channel.send(questions[collectCounter++])
            } else {
                channel.send('Your application has been submitted!')
                collector.stop("fulfilled");
            }
        });
        const APPS_CHANNEL_ID = '822605997356875777'
        const appsChannel = await client.channels.fetch(APPS_CHANNEL_ID)
        collector.on('end', (collected, reason) => {
            if(reason == 'fulfilled') {
                let index = 1;
                const mappedResponses = collected.map((msg) => {
                    return `${index++}) ${questions[endCounter++]}\n-> ${msg.content}`;
                })
                .join('\n\n')
                appsChannel.send(
                    new MessageEmbed()
                        .setAuthor(message.author.tag, message.author.displayAvatarURL({dynamic: true})
                        )
                        .setTitle('New Application')
                        .setDescription(mappedResponses)
                        .setColor('RED')
                        .setTimestamp()
                )
                throw new Error('TOKEN_MISSING');
            }
        });
    },
    }

看起来 client.channels.cache.get('822605997356875777') 返回 undefined。这可能意味着频道没有被缓存。您可以使用 ChannelManager#fetch 获取频道。

您还创建了一个额外的 Client 对象（未登录）并将其传递给 execute 函数。你不需要它。从 const client = new Discord.Client() 中删除 index.js。

并将 command.execute 调用更新为仅发送 message 和 args。

command.execute(message, args)

您可以在 client 函数中从 message 获取 execute 对象。

async execute(message, args) {
  const { client } = message
  // ...

  const APPS_CHANNEL_ID = '822605997356875777'
  const appsChannel = await client.channels.fetch(APPS_CHANNEL_ID)
  // ...
}

请注意，您必须更新所有命令的 execute 函数，因为它们只会收到 message 和 args。

无法读取未定义的属性“发送”
