Discord.js 未将数据写入 .json 文件 [英] Discord.js not writing data to .json file

问题描述

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，它抛出了一个错误，所以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，谢谢您

This is my ban command, im trying to export the code to work within a command handler. Iv had numerous issues with this command but eventually i have almost everything working. The code runs perfectly until the point where it should write to .json file (I changed the .json directory to make sure it was being found, and it threw an error so the previous line of code is definitely running, and its finding the .json). Any help would be greatly appreciated, thank you

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

still results in no data being written to the .json

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

module.exports = {
  config: {
    name: "ban",
    description: "Bans a user from the guild!",
    usage: "!ban",
    category: "moderation",
    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}!` + '**')
          .setThumbnail('https://i.gyazo.com/8988806671312f358509cf0fd69341006.jpg')

        message.channel.send(uEmbed);

      }).catch(err => {
        message.channel.send('I was unable to kick the member');
        console.log(err);
      });
    } else {
      const PREFIX = '!';

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

      let user = message.mentions.users.first(),
        userID = user ? user.id : args[1];

      if (isNaN(args[1])) return message.channel.send("You need to enter a vlaid @Member or UserID #");

      if (args[1].length <= 17 || args[1].length >= 19) return message.channel.send("UserID # must be 18 Digits");

      if (userID) {
        let bannedIDs = require('../../bannedIDs.json').ids || [];

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

        fs.writeFileSync('../../bannedIDs.json', JSON.stringify({ ids: bannedIDs }));
        let reason = args.slice(2).join(' ');

        let uEmbed = new RichEmbed()
          .setTitle('**' + `UserID #${args[1]}
 Will be Banned on Return!` + '**')
          .setThumbnail('https://i.gyazo.com/8988806671312f358509cf0fd69341006.jpg')
          .setImage('https://i.imgur.com/6Sh8csf.gif')
          .setColor(0x320b52)

        message.channel.send(uEmbed);
        let reason1 = args.slice(2).join(' ');
      } else {
        message.channel.send('Error');
      }
    }
  }

};

推荐答案

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，这在 js 中很常见，你通常可以只做 obj &&obj.property 或使用 babel obj?.property

require('../../bannedIDs.json').ids || [] I'm guessing why this doesn't work is because if require(...) doesn't exist, you wouldn't be able to access .id, this is a common thing in js which you can usually just do obj && obj.property or with 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
