表情符号列表命令 Discord.js v12

Question

我创建了一个表情符号列表命令，这里是我的命令代码：

const { MessageEmbed } = require('discord.js');

module.exports = {
    name: "emojis",
    description: "Gets a guild\'s emojis",

    async run (client, message, args) {
 const emojis = [];
    message.guild.emojis.cache.forEach(e => emojis.push(`${e} **-** \`:${e.name}:\``));
 const embed = new MessageEmbed()  
    .setTitle(`Emoji List`)
    .setDescription(emojis.join('\n'))
    message.channel.send(embed)
  }
};

但是，如果嵌入中的字符超过 2048 个字母，我会收到此错误：

(node:211) UnhandledPromiseRejectionWarning: DiscordAPIError: Invalid Form Body
embed.description: Must be 2048 or fewer in length.
    at RequestHandler.execute (/home/runner/Utki-the-bot/node_modules/discord.js/src/rest/RequestHandler.js:170:25)

(node:211) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

机器人有什么办法仍然可以显示表情符号和名称。通过使用不和谐菜单或类似的方式。我无法理解如何做到这一点。你能帮我吗？提前致谢

您可能从错误消息中可以看出，您的嵌入描述太长了。您可以使用string.split() 将您的消息分成几个部分，并将每个缩短的字符串作为单独的消息发送。这是一个基本示例。

const charactersPerMessage = 2000;
  // we're going to go with 2000 instead of 2048 for breathing room
const emojis = message.guild.emojis.cache.map(e=> { return `${e} **-** \`:${e.name}:\`` }); // does virtually the same thing as forEach()
const numberOfMessages = Math.ceil(emojis.length/charactersPerMessage); // calculate how many messages we need

const embed = new MessageEmbed()
                  .setTitle(`Emoji List`);

for(i=0;i<numberOfMessages;i++) {
  message.channel.send(
    embed.setDescription(emojis.slice(i*charactersPerMessage, (i+1)*charactersPerMessage))
  );
}

请注意 emojis 现在是 string 而不是 Array。
