Discord.js 获取用户 DM 和日志消息 [关闭]

Question

我希望我的机器人记录来自特定 ID 的消息，或者如果无法记录所有 DM 消息并发送到不和谐服务器频道。如果特定 ID 发送“Hello！”，机器人将发送“Hello！”到指定的频道ID。

如果您启用了所有必需的 Intent，您只需侦听 messageCreate（message 用于 DiscordJS v12 及更早版本）并检查您的消息来自的频道类型。例如：

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

// Initializing your client
const client = new Client({
  intents: [
    // Intent for catching direct messages
    Intents.DIRECT_MESSAGES,
    // Intents for interacting with guilds
    Intents.GUILDS,
    Intents.GUILD_MESSAGES
  ]
});

// Subscribe to the messages creation event
client.on('messageCreate', async (message) => {
  // Here you check for channel type
  // We only need direct messages here, so skip other messages
  if (message.channel.type !== 'DM')
    return;
  
  // Now we need guild where we need to log these messages
  // Note: It's better for you to fetch this guild once and store somewhere
  // and do not fetch it on every new received message
  const targetGuild = await client.guilds.fetch('YOUR GUILD ID');

  // Here you getting the channel from the list of the guild channels
  const targetLoggingChannel = await targetGuild.channels.fetch('LOGGING CHANNEL ID');
  
  // Sending content of the message to the target channel
  // You can also cover the message into embed with some additional
  // information about sender or time this message was sent
  await targetLoggingChannel.send(message.content);
});

// Authorizing
client.login('TOKEN HERE');

这是一个非常简单的示例，说明如何将来自 bot 的 DM 的消息记录到您想要的任何公会的某个频道。您还应该检查日志通道和公会是否存在以防止错误。还要确保机器人可以向目标频道发送消息。
