Question

我正在尝试开发Discord机器人，当有人添加到服务器时，我希望它发送问候消息。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 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上或其他任何地方尝试过不同的教程，但我不了解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活动。

我发现defaultChannel已过时，但没有找到任何可以满足我需求的东西。

任何人都可以指导我解决此错误吗？

Answer 1

新的不和谐服务器不再具有默认频道，因此Guild#defaultChannel已弃用，并且对于较新的行业协会返回未定义。

如果您希望漫游器仅按名称查找频道，则可以使用：

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，或者可以进行配置以设置日志通道。

Answer 2

由于api的更改，.defaultChannel不再可用。但是，您可以指定名称或ID来选择所需的频道。

带有ID：

guild.channels.find(ch => ch.id === "channel id here".send(`Welcome ${member.user} on my Discord server !`).catch(console.error);

名称：

guild.channels.find(ch => ch.name === "channel name here").send("Welcome ${member.user} on my server Discord !").catch(console.error);
