javascript - 我正在尝试为我的私有(private) Discord JS 机器人执行 Autorole 功能

Question

所以我试图用 Discord JS 做一个 Autorole 函数，但问题是我出现了一个大错误，我不知道为什么。这是我使用的代码:

client.on('guildMemberAdd', member => {
    console.log(`[${b}:${c}` + member.user.tag + 'ist dem Server beigetreten!');

    var role = member.guild.roles.find('name', 'user');
    member.addRole(role);
    member.send('', Embeds.autorole)
});

(我已经在 var 中定义了我的 Angular 色)

错误是:

[${b}:${c}]DoomCity#3747ist dem Server beigetreten!

我不知道如何解决

Answer 1

要删除 DeprecationWarning: Collection#find: pass a function instead 警告，您需要使用:

var role = member.guild.roles.find((role) => role.name === "user");

而不是:

var role = member.guild.roles.find("name", "user");

对于类型错误:提供的参数既不是 Angular 色也不是雪花。，我认为这是因为找不到 Angular 色。尝试在 var 之后添加 console.log。

然后，对于 DiscordAPIError: Cannot send anempty message 错误，这是因为您无法发送空字符串。使用:

member.send(Embeds.autorole);

而不是:

member.send('', Embeds.autorole);
