如何追踪discord.js中删除消息的用户？

Question

我刚刚开始学习如何创建discord机器人，我正在努力弄清楚如何记录谁删除了一条消息。

我尝试了message.author，但当然，那会记录发送消息的人，而我不知道很多语法，所以没有尝试其他任何东西。

您可以使用messageDelete事件，该事件在消息被删除时触发。您可以检查审核日志，以查看用户是否删除了其他用户的消息。

首先，确保您具有所需的意图：Guilds，GuildMembers和GuildMessages。您还需要partials：Channel，Message和GuildMember，以处理在您的机器人上线之前发送的消息。

一旦消息被删除，您可以使用fetchAuditLogs方法来获取被删除消息所在的服务器的审核日志。

const client = new Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildMembers,
    GatewayIntentBits.GuildMessages,
  ],
  partials: [
    Partials.Channel,
    Partials.GuildMember,
    Partials.Message,
  ],
});

client.on('messageDelete', async (message) => {
  const logs = await message.guild.fetchAuditLogs({
    type: AuditLogEvent.MessageDelete,
    limit: 1,
  });
  // logs.entries is a collection, so grab the first one
  const firstEntry = logs.entries.first();
  const { executorId, target, targetId } = firstEntry;
  // Ensure the executor is cached
  const user = await client.users.fetch(executorId);

  if (target) {
    // The message object is in the cache and you can provide a detailed log here
    console.log(`A message by ${target.tag} was deleted by ${user.tag}.`);
  } else {
    // The message object was not cached, but you can still retrieve some information
    console.log(`A message with id ${targetId} was deleted by ${user.tag}.`);
  }
});

在discord.js v14.8+中，有一个新的事件GuildAuditLogEntryCreate。您可以在收到相应的审核日志事件（GuildAuditLogEntryCreate）时立即找出谁删除了消息。它需要启用GuildModeration意图。

const { AuditLogEvent, Events } = require('discord.js');

client.on(Events.GuildAuditLogEntryCreate, async (auditLog) => {
  // Define your variables
  const { action, executorId, target, targetId } = auditLog;

  // Check only for deleted messages
  if (action !== AuditLogEvent.MessageDelete) return;

  // Ensure the executor is cached
  const user = await client.users.fetch(executorId);

  if (target) {
    // The message object is in the cache and you can provide a detailed log here
    console.log(`A message by ${target.tag} was deleted by ${user.tag}.`);
  } else {
    // The message object was not cached, but you can still retrieve some information
    console.log(`A message with id ${targetId} was deleted by ${user.tag}.`);
  }
});
