DiscordJS机器人-如何在通道中紧跟另一条消息之前获取消息？

const Discord = require('discord.js');
const client = new Discord.Client();

client.on('message', async (message) => {
  if (message.content.startsWith('!getPreviousMessage')) {
    // 获取目标消息的ID
    const targetMessageId = message.content.split(' ')[1];

    // 获取目标通道的消息列表
    const channel = message.channel;
    const messages = await channel.messages.fetch({ limit: 100 });

    // 遍历消息列表，找到紧跟在目标消息之前的消息
    let previousMessage = null;
    messages.forEach((msg) => {
      if (msg.id === targetMessageId) {
        return false; // 停止遍历
      }
      previousMessage = msg;
    });

    if (previousMessage) {
      // 获取紧跟消息之前的消息内容
      const content = previousMessage.content;
      const author = previousMessage.author.username;
      const timestamp = previousMessage.createdAt;

      // 处理或展示紧跟消息之前的消息
      message.channel.send(`紧跟在目标消息之前的消息内容：${content}`);
      message.channel.send(`消息作者：${author}`);
      message.channel.send(`消息时间戳：${timestamp}`);
    } else {
      message.channel.send('未找到紧跟在目标消息之前的消息！');
    }
  }
});
