根据参数向特定频道发送消息

Question

我在 Reddit 和 StackOverflow 上搜索并发现了多个论坛帖子，其中用户询问如何将消息发送到特定频道，但我找不到可以使用 Argument 发送到特定频道的帖子。我的意思是你使用

return bot.channels.get(channel).send(embed);

我一直在测试这个“功能”，并设法将消息发送到特定的频道，但它还包括 arg[0] 又名频道 ID。命令是

announce "CHANNEL ID" "MESSAGE"

它确实将带有消息的嵌入发送到我输入的特定频道，但是它将CHANNEL ID 添加到嵌入中，所以我尝试在嵌入的.setDescription(arg[0]) 中使用arg[0]，但它不起作用。它向我吐出一条错误消息，我不知道这是什么意思。但是，如果您的专业人士在那里知道我能做什么，也许一个。这是整个命令代码：

if (cmd === `${prefix}announce`) {
  console.log(message.author.username + " executed an Announcement in the channel #" + message.channel.name);
  const embed = new Discord.RichEmbed()
    .setColor("#e56b00")
    .setAuthor("Announcement from " + message.author.username, message.author.avatarURL)
    .setDescription(arg)
    .setFooter(message.author.username)
    .setTimestamp();

  return bot.channels.get(channel).send(embed);
}

这是错误代码。请注意，仅当我将 arg[0] 放入嵌入的 .setDescription() 部分时才会弹出错误。频道让 arg[1] 正常工作

您可以使用message.mentions 属性。因此，您将执行以下操作：

let announceChannel = message.mentions.channels.first();

然后发送消息执行以下操作； message.guild.channels.find(t => t.id == announceChannel.id).send(myMessage);
