Question

目的：向公会所有者发送消息，然后创建邀请，然后将邀请发送到指定频道。

代码

client.on("guildCreate", async guild => {
    // This event triggers when the bot joins a guild.
    console.log(``);
    console.log(greenBright(`[GUILD JOINED] ${guild.name} | [ID] ${guild.id} | [ (+) MEMBERCOUNT: ${guild.memberCount}]`));
    console.log(``);

    const Owner = guild.ownerID;
    const fetchOwner = client.users.fetch(Owner);
    const InviteLogGuild = client.guilds.cache.get("761134473395306507")
    const InviteLogChannel = InviteLogGuild.channels.cache.find(ch => ch.id === "803512574573543454");
    const getChennel = guild.channels.cache.first();

    (await fetchOwner).send(`Thank you for allowing lovell to  be added to your server, ${guild.name}, ${(await fetchOwner).username} !\nPrefix:\`${prefix}\`\nAll commands are displayed by saying \`${prefix}help\`\nFeel free to join lovell server: ${MainServer}`)
        .then(console.log(cyanBright(`[GUILD OWNER MESSAGED]`)))
        .catch(() => {
            console.error(redBright(`[GUILD OWNER MESSAGE DEINIED]`));
        });

    if (!getChennel) {
        return console.error(redBright('[CHANNEL COULD NOT BE FETCHED]'));
    } else {
        console.log(yellow('[CHANNEL FETCHED]'))
    }

    const link = getChennel.createInvite({
        unique: true,
        maxAge: 0,
        temporary: false,
        maxUses: 100
    })

    if (!link) {
        return console.log(redBright(`[INVITE FAILED]`));
    } else {
        console.log(blueBright(`[INVITE INITIATED]`));
    }

    if (!InviteLogGuild) {
        console.error(red(`\n[LOG GUILD NOT IDENTIFIED]\n`))
    } else if (InviteLogGuild || !InviteLogChannel) {
        console.error(red(`\n[LOG GUILD IDENTIFIED | CHANNEL UNIDENTIFIED]\n`))
    } else if (!InviteLogChannel) {
        console.error(red(`\n[LOG CHANNEL NOT PRESENT]\n`));
    } else if (InviteLogChannel) {
        console.log(cyanBright(`[LOGGING INVITE]`));
        const LogChannel = new Discord.MessageEmbed()
            .setTitle(`New Guild Joined:`)
            .setDescription(`**Guild Name:** ${guild.name} \n\n**MemberCount:** ${guild.memberCount} \n\n**Onwer:** \`${(await fetchOwner).tag}\` \n\n**Invite Link:** ${(await link).url}`)
            .setThumbnail(`${guild.iconURL({ dynamic: true })}`);
        InviteLogChannel.send(LogChannel);
        console.log(cyan(`[INVITE LOGGED]\n`));
    }

});

输出/错误：

[GUILD JOINED] Ghoulish Hangout | [ID] 618894612769275959 | [ (+) MEMBERCOUNT: 23]

[GUILD OWNER MESSAGED]
[CHANNEL FETCHED]
[INVITE INITIATED]

[LOG GUILD IDENTIFIED | CHANNEL UNIDENTIFIED] <---- Error

错误可能伴随着：

(node:12052) UnhandledPromiseRejectionWarning: DiscordAPIError: Unknown Channel

我尝试了多种方法来获取不和谐频道，但它不会发送消息或识别频道。任何帮助将不胜感激;)

我不太清楚为什么这会起作用，但我从 if 语句中取出了我的消息命令并且它起作用了。

    if (!InviteLogGuild) {
        return console.error(red(`\n[LOG GUILD NOT IDENTIFIED]\n`));
    } else if (InviteLogGuild) {
        console.log(greenBright(`[LOG GUILD IDENTIFIED]`));
    } else if (!InviteLogChannel) {
        return console.error(red(`\n[LOG CHANNEL NOT PRESENT]\n`));
    } else if (InviteLogChannel) {
        console.log(cyanBright(`[LOG CHANNEL IDENTIFIED]`));
    } 

    console.log(cyanBright(`[LOGGING INVITE]`));
    const SendMessage = new Discord.MessageEmbed()
        .setTitle(`New Guild Joined:`)
        .setDescription(`**Guild Name:** ${guild.name} \n\n**MemberCount:** ${guild.memberCount} \n\n**Onwer:** \`${(await fetchOwner).tag}\` \n\n**Invite Link:** ${(await link).url}`)
        .setThumbnail(`${guild.iconURL({ dynamic: true })}`);
    InviteLogChannel.send(SendMessage);
    console.log(cyan(`[INVITE LOGGED]\n`));

结果：

[GUILD JOINED] test | [ID] 2389372187328783 | [ (+) MEMBERCOUNT: 9]

[GUILD OWNER MESSAGED]
[CHANNEL FETCHED]
[INVITE INITIATED]
[LOG GUILD IDENTIFIED]
[LOGGING INVITE]
[INVITE LOGGED]

如果有人能解释为什么会这样，请随意！

编辑：

你的 if 语句是错误的：

if (!InviteLogGuild) {
  console.error(red(`\n[LOG GUILD NOT IDENTIFIED]\n`))
} else if (InviteLogGuild || !InviteLogChannel) {

这是错误的，它总是会进入这种情况，因为您正在检查InviteLogGuild是否已定义或 InviteLogChannel是否未定义。由于第一种情况已经检查了要定义的 InviteLogGuild，因此这将始终返回 true。要使其正常工作，您必须将其更改为：

if (!InviteLogGuild) {
  console.error(red(`\n[LOG GUILD NOT IDENTIFIED]\n`))
} else if (InviteLogGuild && !InviteLogChannel) {

但是您可以完全删除 &&，因为第一种情况已经检查了 InviteLogGuild 是否已定义：

if (!InviteLogGuild) {
  console.error(red(`\n[LOG GUILD NOT IDENTIFIED]\n`))
} else if (!InviteLogChannel) {

如果您将这些因素考虑在内，您最终的“if-chain”将如下所示（并且有效）：

if (!InviteLogGuild) {
  console.error(red(`\n[LOG GUILD NOT IDENTIFIED]\n`));
} else if (!InviteLogChannel) {
  console.error(red(`\n[LOG GUILD IDENTIFIED | CHANNEL UNIDENTIFIED]\n`));
} else {
  console.log(cyanBright(`[LOGGING INVITE]`));
  const LogChannel = new Discord.MessageEmbed()
    .setTitle(`New Guild Joined:`)
    .setDescription(`**Guild Name:** ${guild.name} \n\n**MemberCount:** ${guild.memberCount} \n\n**Onwer:** \`${(await fetchOwner).tag}\` \n\n**Invite Link:** ${(await link).url}`)
    .setThumbnail(`${guild.iconURL({ dynamic: true })}`);
  InviteLogChannel.send(LogChannel);
  console.log(cyan(`[INVITE LOGGED]\n`));
}

为了避免此类问题，我建议您改用 TypeScript 或开始使用 ESLint，它可以建议您进行不必要的检查。

旧答案

尝试使用 guild.channels.resolve(channelId) 和 client.guilds.resolve(guildId) 而不是使用缓存。可能是频道还没有加载到缓存中，找不到。

无法在获取的频道中发送消息 | Discord.js
