【问题描述】：

我想知道如何使用!clear [number] 之类的命令删除消息并将这些消息提取回一个频道，包括：

使用命令删除消息的用户ID 删除消息的用户 ID 消息的内容 它已被删除的频道 消息的时间戳

所有这些东西都在一个不和谐的嵌入中。 我对编码比较陌生，我正在为一个有 40,000 人的服务器开发这个机器人，我们需要保留所有已删除消息的日志。

请有人帮帮我。我将不胜感激：D。如果需要，如果您仍然不确定我想用这个机器人做什么，我可以更详细地解释：D

要使用命令删除消息，您必须使用TextChannel.bulkDelete()，在这种情况下，可能是在通过TextChannel.fetchMessages() 获取消息之后。 要“记录”它们，您可能需要建立一个 RichEmbed 并将您的信息放在字段中。 我会尝试这样的事情：

// ASSUMPTIONS:
// logs = the TextChannel in wich you want the embed to be sent
// trigger = the Messages that triggered the command
// 
// This is just a sample implementation, it could contain errors or might not be the fastest
// Its aim is not to make it for you, but to give you a model

async function clear(n = 1, logs, trigger) 
  let channel: source, author = trigger;
  if (n < 1 || !logs || !source) throw new Error("One of the arguments was wrong.");

  let coll = await source.fetchMessages( limit: n ), // get the messages
    arr = coll.array(),
    collected = [],
    embeds = [];

  // create groups of 25 messages, the field limit for a RichEmbed
  let index = 0;
  for (let i = 0; i < arr.length; i += 25) 
    collected.push([]);
    for (let m = i; m < i + 25; m++)
      if (arr[m]) collected[index].push(arr[m]);
    index++;
  

  // for every group of messages, create an embed
  // I used some sample titles that you can obviously modify
  for (let i = 0; i < collected.length; i++) 
    let embed = new Discord.RichEmbed()
      .setTitle(`Channel cleaning$collected.length > 1 ? ` - Part $i+1` : ""`)
      .setDescription(`Deleted from $source`)
      .setAuthor(`$author.tag ($author.id)`, author.displayAvatarURL)
      .setTimestamp(trigger.editedAt ? trigger.editedAt : trigger.createdAt),
      group = collected[i];
    for (let msg of group) 
      let a = `$msg.author.tag ($msg.author.id) at $msg.editedAt ? msg.editedAt : msg.createdAt`,
        c = msg.content.length > 1024 ? msg.content.substring(0, msg.content.length - 3) + '...' : msg.content;
      embed.addField(a, c);
    
    embeds.push(embed);
  

  // once the embeds are ready, you can send them
  source.bulkDelete(coll).then(async () => 
    for (let embed of embeds) await source.send(embed);
  ).catch(console.error);


// this is a REALLY basic command implementation, please DO NOT use this as yours
client.on('message', async msg => 
  let command = 'clear ';
  if (msg.content.startsWith(command)) 
    let args = msg.content.substring(command.length).split(' ');
    if (isNaN(args[0]) || parseInt(args[0]) < 1) msg.reply(`\`$args[0]\` is not a valid number.`);
    else 
      await msg.delete(); // delete your message first
      let logs; // store your channel here
      clear(parseInt(args[0]), logs, msg);
    
  
);

注意：这种带有大量反引号字符串和对象的东西的高亮显示非常糟糕。我建议在另一个编辑器中阅读代码，否则您可能最终什么都不懂
