如何获取带有 ID 的消息，而不将其放入缓存中

Question

所以我编写了一个系统来保存某些频道（加上消息）的 ID 并将它们保存在一个文件中。重启机器人后，ID 将被读取并重复使用。因此，例如，获取特定消息以对其进行编辑。不幸的是，缓存未定义、为空或发生错误。有人可以告诉我如何获取不在缓存中的消息吗？

现有消息和频道的示例代码：

const {Discord, Client, Intents, Permissions, MessageEmbed} = require('discord.js');
const bot = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MEMBERS, Intents.FLAGS.GUILD_MESSAGES, Intents.FLAGS.GUILD_MESSAGE_REACTIONS, Intents.FLAGS.GUILD_MESSAGE_TYPING, Intents.FLAGS.GUILD_PRESENCES, Intents.FLAGS.DIRECT_MESSAGES, Intents.FLAGS.DIRECT_MESSAGE_REACTIONS, Intents.FLAGS.DIRECT_MESSAGE_TYPING, Intents.FLAGS.GUILD_VOICE_STATES]});

bot.channels.cache.get('597102497420673025').messages.cache.get('959413368911966251').embeds;

错误：

var test = bot.channels.cache.get('597102497420673025').messages.cache.get('959413368911966251').embeds;
                                                                                                  ^

你fetch留言，给cache吧。

// asynchronously
const channel = client.channels.cache.get(`channelId`);
const message = await channel.messages.fetch(`messageId`);
return message.embeds;

// synchronously
const channel = client.channels.cache.get(`channelId`);
channel.messages.fetch(`messageId`).then(message => {
   return message.embeds;
})

希望这能解决您的问题！
