使用 Embed 列出没有角色的用户在太多时会出错

【中文标题】使用 Embed 列出没有角色的用户在太多时会出错

【英文标题】：Listing users without roles with Embed getting error when too many

【发布时间】：2021-10-04 17:46:37

【问题描述】：

当没有角色的用户只有大约 1-15 个用户列表时它可以工作，但是当它超过 100 个用户时它无法打印并且它给出错误，这是说它达到了文本的限制嵌入..你们能帮我了解如何生成具有页面功能的列表吗？

编辑：人们说阅读错误，我知道错误超出了嵌入的限制，我试图寻求帮助是一种为嵌入创建动态页面的方法，我已经尝试过 discord.js-pagination 但没有希望它是手动创建而不是动态的。

顺便说一下，我使用 discord.js 和 ^12.5.1

版本

    require ('dotenv').config()
    const Discord = require('discord.js');
    const usedCommand = new Set();
    const config = process.env;

    module.exports.run = async (bot, message, args) => 
        if(usedCommand.has(message.author.id))
            message.reply("You cannot use " + config.prefix + "unorole command beacuse of the cooldown.")
         else 
            if (message.content.toLowerCase().startsWith(config.prefix + "unorole")) 
                //check if no perm
                if(!message.member.hasPermission("ADMINISTRATOR"))
                  return message.reply("You don't have `ADMINISTRATOR` permission to do that!");
                  
                    
                  var memberscount = message.guild.members.cache.filter(member => member.roles.cache.array().length < 2).size;
            
                    if (memberscount == 0)
                    message.reply('Looks like everyone has a role already.') 
                    
                    else  
                    
                    //Embed List of users without role
                    const ListEmbed = new Discord.MessageEmbed() 
                   .setTitle(`Prune Bot | Users`)
                   .setDescription(`Users that has no role.`)
                   .setColor('#b491c8')
                   .addFields(
                   name: 'Users:', value: message.guild.members.cache.filter(member => member.roles.cache.array().length < 2).map(member => member.user.tag).join('\n') ,)
                 .setFooter('PruneBot is created by Mashwishi', 'https://i.imgur.com/DxWDaGv.png');
                 message.channel.send(ListEmbed);  
                  
                     
            
            usedCommand.add(message.author.id);
            setTimeout(() => 
                usedCommand.delete(message.author.id);
            , 5000); 
        
    

    module.exports.config = 
        name: "unorole",
        description: "",
        usage: "?unorole",
        accessableby: "Admins",
        aliases: []
    

我也试过正常的消息发送

message.channel.send(`Users that has no role.`);    
message.channel.send(message.guild.members.cache.filter(member => member.roles.cache.array().length < 2).map(member => member.user.tag).join('\n'))

错误：

【问题讨论】：

我有一个简短的问题，与您的问题无关，但是您为什么要过滤掉少于 2 个角色的成员？

我想我当时是因为意图而设置的..

【参考方案1】：

我已经修好了。

【参考方案2】：

错误清楚地表明消息太长。限制消息的长度。
