node.js - 如何将本地文件附加到嵌入？

问题描述

const Discord = require('discord.js');
const {Client, MessageAttachment} = require('discord.js');
const bot3 = new Client();


const mark2 = '*info personal'
const mark3 = '*info guild'
const mark4 = '*info roles'
bot3.on('message', msg =>{

    if (msg.content.startsWith(mark2)){
        const hashitag = msg.author.id
        const actualhashitag = msg.author.discriminator
        const evenbetterhashitag = "#" + actualhashitag 
        const personalembed = new Discord.MessageEmbed()
            .setTitle('Stuff about you')
            .setImage(msg.author.displayAvatarURL())
            .setColor('#D11111')
            .addField('Your username',  msg.author.username)
            .addField('Your hashtag', hashitag, true)
            .addField('Your actual hashtag', actualhashitag, true)
            .addField('Your even realer hashtag', evenbetterhashitag, true)   
            .addField('Your amount of friends', 'Discord bots can not know that sadly')
            .addField('Your role', msg.member.roles.cache.map(role => role.name).join(", ") )
            .addField('Your role id', msg.member.roles.cache.map(role => role.id).join(", ") )
            .addField('Your nickname', msg.member.nickname);
        msg.channel.send(personalembed)
    }
    if (msg.content.startsWith(mark3)){




        const guildembed = new Discord.MessageEmbed()

            .setTitle(msg.guild.name)
            .setImage(msg.guild.iconURL())
            .setColor('#97FF00')
            .addField('the id of the server', msg.guild.id)
            .addField('the owner', msg.guild.owner.user.username)
            .addField('the owner tag', msg.guild.owner.user.tag)
            .addField('the owner id', msg.guild.ownerID)
            .addField('the owner nickname', msg.guild.owner.nickname)
            .addField('all roles', msg.guild.roles.cache.map(role => role.name).join(", ") ) 
            .addField('the bots', msg.guild.members.cache.filter(member => member.user.bot).map(member => member.user.tag).join(' | '))
            .addField('the bots actual name', msg.guild.members.cache.filter(member => member.user.bot).map(member => member.user.username).join(' | '))
            .addField('the bot ids', msg.guild.members.cache.filter(member => member.user.bot).map(member => member.user.id).join(' | '))
            .addField('the bots hashtag(without the hashtag)', msg.guild.members.cache.filter(member => member.user.bot).map(member => member.user.discriminator).join(' | '))
        msg.channel.send(guildembed)

    }  

    if(msg.content.startsWith(mark4)){
        const attachmento = new MessageAttachment('./stuff\role5.png', 'name') 
        const roleembed = new Discord.MessageEmbed()
            .setTitle('All roles and the people with the roles')
            .attachFiles(attachmento)
            .setThumbnail(attachmento)
            .setColor('FFA737')
        msg.channel.send(roleembed)
    }


})

bot3.login(process.env.token3)

如果您想知道，discord.js 版本是 12.2.0。我想将图像附加到第三个嵌入（忽略嵌入的标题，我稍后会尝试处理）它是一个名为 role5 的本地文件。我似乎无法将该文件附加到嵌入中。这就是发生的事情。

解决方案

从discord.js 文档中，创建嵌入时，您需要使用.attachFiles()将本地文件附加到嵌入。之后，您可以attachment://fileName.extension在设置嵌入图像/图标时使用。

嵌入角色的示例：

const roleembed = new Discord.MessageEmbed()
            .setTitle('All roles and the people with the roles')
            .attachFiles('./stuff/role5.png')
            .setThumbnail("attachment://role5.png")
            .setColor('FFA737')
        msg.channel.send(roleembed)
