javascript - 未使用“messageReactionAdd”事件定义消息以执行操作

问题描述

我希望我的机器人对“message.member”执行操作，因为该成员对来自我的机器人的消息使用某个表情符号做出反应。但是，我有一个错误“未定义消息”，我对此无能为力。

我想我需要使用“messageReactionAdd”，因为我需要知道服务器上的每个反应，检查它们是否应用于我的机器人消息，然后将操作返回给执行它们的用户。这必须涉及来自我的机器人的所有消息，甚至是旧消息。我想使用的所有方法都是 GuildMember 的方法：https ://discord.js.org/#/docs/main/stable/class/GuildMember 。

client.on('messageReactionAdd', (reaction, user) => {
  console.log(`mess id : ${reaction.message.id} emoji user = ${reaction.message.member.id}`);
    if ((reaction.message.author.id == client.user.id) && (user.id != client.user.id)) {
      if (reaction.emoji.name == '') {
        message.member.send('You picked   '); 
      }
    }
  });

解决方案

我确实添加了“reaction.message [...]”，但看不到该消息。所以我把“.nickname”方法放上来看看是否有效。但是我将昵称更改为他自己，而不是做出表情反应的用户。请问有什么帮助吗？

client.on('messageReactionAdd', (reaction, user) => {
  console.log(`mess id : ${reaction.message.id} emoji user = ${reaction.message.member.id}`);
    if ((reaction.message.author.id == client.user.id) && (user.id != client.user.id)) {
      if (reaction.emoji.name == '') {
        reaction.message.member.setNickname('')
        .then(console.log)
        .catch(console.error);
      }
    }
  });
