【问题描述】:

我得到一个解禁命令代码,我在控制台中得到以下错误:

(node:9348) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'member' of undefined 在 Object.execute (C:\Users\19nik\Documents\GitHub\bot-project\commands\unban.js:9:22) 在客户端。 (C:\Users\19nik\Documents\GitHub\bot-project\gb.js:81:17) 在 Client.emit (events.js:315:20) 在 MessageCreateAction.handle (C:\Users\19nik\Documents\GitHub\bot-project\node_modules\discord.js\src\client\actions\MessageCreate.js:31:14) 在 Object.module.exports [as MESSAGE_CREATE] (C:\Users\19nik\Documents\GitHub\bot-project\node_modules\discord.js\src\client\websocket\handlers\MESSAGE_CREATE.js:4:32) 在 WebSocketManager.handlePacket (C:\Users\19nik\Documents\GitHub\bot-project\node_modules\discord.js\src\client\websocket\WebSocketManager.js:384:31) 在 WebSocketShard.onPacket (C:\Users\19nik\Documents\GitHub\bot-project\node_modules\discord.js\src\client\websocket\WebSocketShard.js:444:22) 在 WebSocketShard.onMessage (C:\Users\19nik\Documents\GitHub\bot-project\node_modules\discord.js\src\client\websocket\WebSocketShard.js:301:10) 在 WebSocket.onMessage (C:\Users\19nik\Documents\GitHub\bot-project\node_modules\ws\lib\event-target.js:132:16) 在 WebSocket.emit (events.js:315:20)

这是我的代码:

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

module.exports = {
    name: `unban`,
    description: `Unbans given user ID or mentioned user.`,
    async execute(bot, args, message) {

        if (!message.member.hasPermission(["BAN_MEMBERS"])) return message.channel.send("You do not have the required permissions to use the unban command.")

        if (!args[0]) return message.channel.send("Provide me a valid USER ID.");
        //This if() checks if we typed anything after "!unban"

        let bannedMember;
        //This try...catch solves the problem with the await
        try {
            bannedMember = await bot.users.cache.fetch(args[0])
        } catch (e) {
            if (!bannedMember) return message.channel.send("That's not a valid USER ID.")
        }

        //Check if the user is not banned
        try {
            await message.guild.fetchBan(args[0])
        } catch (e) {
            message.channel.send('This user is not banned.');
            return;
        }

        let reason = args.slice(1).join(" ")
        if (!reason) reason = "No reason provided."

        if (!message.guild.me.hasPermission(["BAN_MEMBERS"])) return message.channel.send("I am missing permissions to unban.")
        message.delete()
        try {
            message.guild.members.unban(bannedMember, { reason: reason })
            message.channel.send(`${bannedMember.tag} has been unbanned.`)
            console.log(`AUDIT LOG: [UNBAN] ${message.author.tag} unbanned ${member.user.tag} from ${message.guild.name}.`);
            var readmessagefile = fs.readFileSync('./logging/UnbanLog.txt', 'utf-8');
            var writemessagefile = fs.writeFileSync('./logging/UnbanLog.txt', 'Type: [UNBAN] ' + 'Time ' + '(' + message.createdAt + ')' + ' | ' + member.user.tag + ' from ' + message.guild.name + ' | Moderator ' + message.author.tag + '\n' + readmessagefile)
            console.log('BOT LOG: [INTERNAL] Writing to unban log file.');
        } catch (e) {
            console.log(e.message)
        }
    }
}

我不知道该怎么办。它还弹出无法读取未定义的属性'hasPermissions'的错误。

【问题讨论】:

  • 看来message 是未定义的。你检查过它的价值吗?
  • 我已将消息放在异步执行()上。我必须把它放在别的地方吗
  • 你应该edit your post 并添加你如何调用.execute() 函数。
  • 我确实包含了 async execute() 。但是,不用担心。有人给了我一个解决方案,但遇到了一个不同的问题......

【解决方案1】:

我相信您的问题的主要来源是您的回调,在 messageargs 之前先调用了您的 client。 由于 JS 对回调参数的放置很敏感,因此您应该将回调编写如下:

async execute(message, args, bot)

【讨论】:

  • 现在试试这个。
  • 修复了无法读取的错误,但我现在遇到了一个新问题。我使用的用户 ID 已在服务器中被禁止,但机器人在聊天中返回以下消息,请提供有效的用户 ID。
【解决方案2】:

第 9 行似乎有错误

if (!message.member.hasPermission(["BAN_MEMBERS"])) return message.channel.send("You do not have the required permissions to use the unban command.")

哪个没有错误,也许该命令是在 DMS 中运行的?也许使用:

if(!message.guild) return;

这应该可以解决问题。

【讨论】:

    【解决方案3】:

    两个可能的原因:

    回调

    确保 execute() 的参数与主文件中的顺序完全相同

    命令在公会外使用

    错误可能是因为该命令在公会外部使用来修复此问题,请将其添加到执行()下方的代码中

    if (!message.guild) return;

      【解决方案4】:

      const findUser = message.guild.members.cache.get(message.author.id)
      if(!findUSer) return;
      const isMemberHavePermission = findUser.hasPermission("BAN_MEMBERS")
      iF(isMemberHavePermission){
        // Member Have Permission
       }else{
        // Member Have not Permission
       }

      【讨论】:

      • 请在您的回答中提供更多详细信息。正如目前所写的那样,很难理解您的解决方案。
      【解决方案5】:

      非常确定您使用的是 discord.js v12,还请确保您使用的是 node.js 的最新(或 v14)版本,如果不是至少在 v14 中,请在https://node.js.org下载

      这是来自我的机器人,试试这个,它有效,我已将其更改为您的处理程序:

      
      const { MessageEmbed } = require("discord.js")
      const fs = require("fs")
      
      module.exports = {
        name: "unban",
        description: "Unbans given user ID or mentioned user.",
        async execute(bot, message, args) {
          
          if (!message.member.hasPermission('BAN_MEMBERS')) return message.channel.send(`You need the permission **Ban Members** to execute this command.`)
          if (!message.guild.me.hasPermission('BAN_MEMBERS')) return message.channel.send(`**${client.user.tag}** needs the permission **Ban Members** to execute this command.`)
          
          const id = args[0];
          
          if (!id) return message.channel.send(`Please mention the user's ID to unban.`)
      
      const bannedMember = client.users.fetch(args[0]);    
      
          const bans = await message.guild.fetchBans();
          if (bans.size == 0) return message.channel.send(`There are no users banned on this server.`);
          let bUser = bans.find(b => b.user.id == id);
          if(!bUser) return message.channel.send(`This user is not banned or was not found.`)
      
            const reason = args.slice(1).join(" ")
            if (!reason) return message.channel.send('Please include a reason!');
      
          try {
                          message.guild.members.unban(bannedMember, { reason: reason })
                  message.channel.send(`${bannedMember.tag} has been unbanned.`)
                  console.log(`AUDIT LOG: [UNBAN] ${message.author.tag} unbanned ${member.user.tag} from ${message.guild.name}.`);
                  var readmessagefile = fs.readFileSync('./logging/UnbanLog.txt', 'utf-8');
                  var writemessagefile = fs.writeFileSync('./logging/UnbanLog.txt', 'Type: [UNBAN] ' + 'Time ' + '(' + message.createdAt + ')' + ' | ' + member.user.tag + ' from ' + message.guild.name + ' | Moderator ' + message.author.tag + '\n' + readmessagefile)
                  console.log('BOT LOG: [INTERNAL] Writing to unban log file.');
      
           } catch (e) {
            console.error(e);
      }
       }
      }

        【解决方案6】:

        我认为这会奏效。

        const { MessageEmbed } = require('discord.js');
        const fs = require("fs");
        
        module.exports = {
            name: `unban`,
            description: `Unbans given user ID or mentioned user.`,
            async execute(bot, args, message) {
                if(!message.guild) return message.channel.send("This Command Can't Be Executed In DMs.");
                if (!message.author.hasPermission(["BAN_MEMBERS"])) return message.channel.send("You do not have the required permissions to use the unban command.")
        
                if (!args[0]) return message.channel.send("Provide me a valid USER ID.");
                //This if() checks if we typed anything after "!unban"
        
                let bannedMember;
                //This try...catch solves the problem with the await
                try {
                    bannedMember = await bot.users.cache.fetch(args[0])
                } catch (e) {
                    if (!bannedMember) return message.channel.send("That's not a valid USER ID.")
                }
        
                //Check if the user is not banned
                try {
                    await message.guild.fetchBan(args[0])
                } catch (e) {
                    message.channel.send('This user is not banned.');
                    return;
                }
        
                let reason = args.slice(1).join(" ")
                if (!reason) reason = "No reason provided."
        
                if (!message.guild.me.hasPermission(["BAN_MEMBERS"])) return message.channel.send("I am missing permissions to unban.")
                message.delete()
                try {
                    message.guild.members.unban(bannedMember, { reason: reason })
                    message.channel.send(`${bannedMember.tag} has been unbanned.`)
                } catch (e) {
                    console.log(e.message)
                }
            }
        }
        

        我删除了控制台日志记录部分,因为它可能会开始出现一些错误。

        我是新手,可能是错误的
