javascript - Discord.js v12 表情符号列表命令

Question

我正在尝试在 discord.js v12 中创建一个表情符号列表命令。但是，如果我在具有许多表情符号的服务器中运行该命令，则会收到 Invalid Form Body 错误，因为嵌入描述不能超过 2048 个字符。因此，我试图拆分消息。这是我的代码：

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

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

 async run(client, message, args) {
  const charactersPerMessage = 2000;
  const emojis = message.guild.emojis.cache.map((e) => {
   return `${e} **-** \`:${e.name}:\``;
  });
  const numberOfMessages = Math.ceil(emojis.length / charactersPerMessage);
  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)
    )
   );
  }
 },
};

即使在此之后，我也会收到相同的 Invalid Body Form 错误。这是我得到的错误：

(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)

你能帮我吗？提前致谢！

问题在于它emojis是一个数组，而不是一个字符串。该.map函数返回一个数组（在您的情况下为字符串）。修复应该很简单，只需.join在函数末尾添加一个.map使其成为字符串即可。检查下面的代码：

const emojis = message.guild.emojis.cache
 .map((e) => `${e} **-** \`:${e.name}:\``)
 .join(', ');
