从另一个分片缓存自定义表情符号

im试图获得一个更大的我的不和谐机器人，以将它从另一个分片抓取的所有自定义表情符号保存到缓存中，以便为每个分片提供更好的响应时间。举一个理论上的例子，我的机器人生成了4个分片，并且只有一个分片服务于行会，该行会包含我要在所有分片中使用的所有自定义表情符号。我正在使用此功能来捕获表情符号，但是我需要等待每个表情符号，由于需要捕获许多表情符号，它可以使我的响应时间长达15秒。

function findEmoji(id) {
    const temp = this.emojis.get(id);
    if (!temp) return null;

    const emoji = Object.assign({}, temp);
    if (emoji.guild) emoji.guild = emoji.guild.id;
    emoji.require_colons = emoji.requiresColons;

    return emoji;
  }
  async function grabEmoji(emojiID) {
    const emojiArray = await client.shard.broadcastEval(`(${findEmoji}).call(this, '${emojiID}')`);

    const foundEmoji = emojiArray.find(emoji => emoji);
    if (!foundEmoji) return;

    const raw = await client.rest.makeRequest('get', Discord.Constants.Endpoints.Guild(foundEmoji.guild).toString(), true);
    const guild =  new Discord.Guild(client, raw);
    const emoji =  new Discord.Emoji(guild, foundEmoji);

    return await emoji;
  }
// then when I send the message, I call the function with the said ID of the emoji I want:
await grabEmoji("530800350656200705");

另一方面，当我删除await时，它将给我侦听器错误（达到maxListeners）或其他，然后显示“ null”。

这是我尝试过的方法，但我无法使其正常工作。

const emojiMap = new Map();
createMap();
async function createMap() {
  let woodenPick = await grabEmoji("601256699629797379"),

}

client.on('message', ... //rest of the code continues for my command handler.

//grab emojis
  let woodenPick =   emojiMap.get('woodenPick')
  let stonePick =   emojiMap.get('stonePick')
  let ironPick =   emojiMap.get('ironPick')

  let staffBadge =   emojiMap.get('staffBadge')
  let donatorBadge =   emojiMap.get('donatorBadge')
  let contributorBadge =   emojiMap.get('contributorBadge')

这样做返回未定义，如下所示：resulting message

有人有什么想法吗？我直接将表情符号对象保存到地图上，以为以后可以使用。

完全没有必要获得discord.js对Emoji对象的抽象以便将其显示在消息中，但我不能怪您，因为discord.js倾向于将其用户推向这些种类实践。

您已经知道表情符号名称和ID。您不需要从您的机器人尚不具备的其他分片中获取其他信息。在Discord消息中，自定义表情符号表示如下：

Custom Emoji            - <:NAME:ID>  -> <:mmLol:216154654256398347>

Custom Emoji (Animated) - <a:NAME:ID> -> <a:b1nzy:392938283556143104>

来源：discord api docs reference

因此，您不需要发出任何请求，任何广播评估或任何种类的事情：您只需要静态数据。像这样：

let emojiMap = {
  woodenPick: "601256699629797379",
  stonePick: "601256431076769803",
  //etc
};

我建议使用util函数将表情符号放入消息中

function getEmoji(name) {
  return `<:${name}:${emojiMap[name]}>`;
}

像这样使用它：

await msg.react(emojiMap.woodenPick); //might need to be :name:id
//etc, probably use an array for that (or Object.keys(emojiMap))

//make embed
let description = `${getEmoji("woodenPick")} --> Wooden Pickaxe\netc...`;
