Question

我已经搜索并在Reddit和StackOverflow上找到了多个论坛帖子，用户正在询问如何向特定频道发送消息，但是我找不到可以使用Argument发送至特定频道的帖子。我的意思是您使用

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

我一直在使用此“功能”进行测试，并设法将消息发送到特定的频道，但是它也包含arg [0]，也就是频道ID。命令是

announce "CHANNEL ID" "MESSAGE"

它确实将嵌入的消息发送到我输入的特定频道，但是它向嵌入中添加了CHANNEL ID，所以我尝试在嵌入的arg[0]中使用.setDescription(arg[0])，但是它没有用。它向我吐出了一条错误消息，我不知道这意味着什么。但是，如果您是专业人士，也许有人知道我能做什么。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。该频道让arg[1]

可以正常工作

Answer 1

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，请执行以下操作； message.guild.channels.find(t => t.id == announceChannel.id).send(myMessage);

根据参数将消息发送到特定频道
