如何使用 Discord 机器人发送问候消息 - NodeJS

Question

我正在尝试开发一个 Discord 机器人，我希望它在有人添加到服务器时发送问候消息。我收到此错误：

/perso-workspace/discordtest/index.js:31
guild.defaultChannel.send(`Bienvenue ${member.user} sur mon serveur Discord !  `).catch(console.error);
                         ^

TypeError: Cannot read property 'send' of undefined
    at Client.bot.on.member (/home/spoisson/Documents/perso-workspace/discordtest/index.js:31:26)
    at Client.emit (events.js:189:13)

    at Receiver._receiver.onmessage (/home/spoisson/Documents/perso-workspace/discordtest/node_modules/ws/lib/websocket.js:137:47)

这是我的代码：

const Discord = require('discord.js')
const bot = new Discord.Client()


bot.on('ready', function(){
    console.log('I am ready to learn !')
})

bot.on('message', function (message){
    if (message.content === '!ping') {
        message.channel.send('Pong !')
    }
})

bot.on("guildMemberAdd", member => {
    let guild = member.guild;
    console.log('Guild is ' + guild + ' and member is ' + member.user)
    guild.defaultChannel.send(`Bienvenue ${member.user} sur mon serveur Discord !  `).catch(console.error);
});

bot.login('i_set_my_token_here')

我已经在 YouTube 或其他网站上尝试过不同的教程，但我不明白我与正在观看的人之间的区别。第一个命令 ( !ping ) 运行良好。我设法为我的机器人设置了 activity。

我看到 defaultChannel 已被弃用，但我没有找到任何符合我想要的内容。

谁能指导我解决/更正此错误？

Answer 1

新的 Discord 服务器不再有默认频道，因此 Guild#defaultChannel 已弃用并且 returns 未为新公会定义。

如果您希望机器人仅通过名称查找频道，您可以使用：

guild.channels.find(channel => channel.name === 'general-chat');

您还可以遍历可能的通道名称列表以允许更多通道，或者您可以有一个设置日志通道的配置。
