Discord.js 未将数据写入 .json 文件

Question

这是我的禁令命令，我试图导出代码以在命令处理程序中工作。 Iv 这个命令有很多问题，但最终我几乎可以正常工作。代码运行完美，直到它应该写入 .json 文件（我更改了 .json 目录以确保它被找到，并且它抛出了一个错误，因此前一行代码肯定正在运行，并且它找到了 .json 文件。 json）。任何帮助将不胜感激，谢谢

我也试过替换这条线

let bannedIDs = require('../../bannedIDs.json').ids || []

与

let file = fs.readFileSync('../../bannedIDs.json')
let bannedIDs = JSON.parse(file).ids || []

仍然没有数据写入 .json

const { RichEmbed } = require("discord.js");
const fs = require('fs');

module.exports = {
  config: {
    name: "ban",
    description: "Bans a user from the guild!",

    accessableby: "Administrators",
    aliases: ["b", "banish", "remove"]
  },
  run: async (bot, message, args) => {

    if (!message.member.hasPermission(["BAN_MEMBERS", "ADMINISTRATOR"])) return message.channel.send("You do not have permission to perform this command!");

    const user1 = message.mentions.users.first();
    let member = message.mentions.members.first();


    if (member) {

      const member = message.mentions.members.first();

      let reason = args.slice(2).join(' ');
      var user = message.mentions.users.first();

      member.ban({ reason: `${args.slice(2).join(' ')}` }).then(() => {
        let uEmbed = new RichEmbed()
          .setTitle('**' + `Sucessfully Banned ${user1.tag}!` + '**')

      let args = message.content.substring(PREFIX.length).split(" ");

      let user = message.mentions.users.first(),

        if (!bannedIDs.includes(userID)) bannedIDs.push(userID);

        fs.writeFileSync('../../bannedIDs.json', JSON.stringify({ ids: bannedIDs }));

Answer 1

require('../../bannedIDs.json').ids || []我猜为什么这不起作用是因为如果require(...)不存在，您将无法访问.id，这是js中常见的事情，您通常可以只需执行obj && obj.property 或使用 babel obj?.property

这是我个人的做法

let file = require('../../bannedIDs.json') || { ids: [userID] };
const bannedIDs = file.bannedIDs;

if (!bannedIDs.includes(userID)) bannedIDs.push(userID);

fs.writeFile('../../bannedIDs.json', JSON.stringify(file));

你也可以这样做

const collection = await <Guild>.fetchBans();
const ids = collection.map(e => e.user.id).array();

获取被禁止用户或 ID 的列表
