channels.fetchMessage 在原始事件中未触发

Question

我正在尝试制作一个 Discord 机器人，它会根据反应给出一个角色。目前，我正在测试原始事件是否会触发。

我不知道为什么，但是 channels.fetchMessage 不会触发 .then，我尝试手动输入仍然不会响应的频道 ID。

我在 Discord.js ^12.1.1 上运行

这不是完整的代码示例，因为我在最后取出了客户端登录

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

client.on("ready", async () => {

    client.user.setActivity('Redacted');

});

client.on('raw', packet => {
    // We don't want this to run on unrelated packets
    if (!['MESSAGE_REACTION_ADD', 'MESSAGE_REACTION_REMOVE'].includes(packet.t)) return;


    // Grab the channel to check the message from
    const channel = client.channels.cache.get(packet.d.channel_id);

    // There's no need to emit if the message is cached, because the event will fire anyway for that
    //if (channel.messages.has(packet.d.message_id)) return;


    // Since we have confirmed the message is not cached, let's fetch it
    console.log("Passed")


    channel.fetchMessage(packet.d.message_id).then(message => {

        console.log("Passed Again")


        // Emojis can have identifiers of name:id format, so we have to account for that case as well
        const emoji = packet.d.emoji.id ? `${packet.d.emoji.name}:${packet.d.emoji.id}` : packet.d.emoji.name;


        // This gives us the reaction we need to emit the event properly, in top of the message object
        const reaction = message.reactions.get(emoji);


        // Adds the currently reacting user to the reaction's users collection.
        if (reaction) reaction.users.set(packet.d.user_id, client.users.get(packet.d.user_id));


        // Check which type of event it is before emitting
        if (packet.t === 'MESSAGE_REACTION_ADD') {
            console.log("yes")
        }


        if (packet.t === 'MESSAGE_REACTION_REMOVE') {
            console.log("no")
        }
    });
});

您获取频道的方式不正确，您需要获取 GuildChannel。

您的解决方案是：

const channel = client.guilds.cache.get(guildID).channels.cache.get(channelID);

channel.messages.fetch(messageID);
