检查用户是否在特定的公会中 discord.js

问题描述

我不知道这是否可能，但我正在尝试让我的机器人返回它与用户共享的所有服务器.

I don't know if it's possible, but I'm trying to make my bot returning all the servers it shares with an user.

所以我从 bot 所在的公会那里获得了所有 id，以及来自用户的 id.

So I got all the ids from the guilds' where the bot is, and the id from the user.

而且我不知道如何检查每个公会是否有用户的 id.

And I don't know how to check for each guild if the user's id is on it or not.

我尝试过这样做:

let user_id = message.author.id;

let guild_list = [];

client.guilds.cache.forEach(guild => {
    guild_list.push(guild.id);
    })

for (let i = 0; i < guild_list.length; i++){

    let thisGuild = client.guilds.cache.get(guild_list[i]);

    if(thisGuild.member(user_id)){

        message.channel.send("Shared server : " + guild_list[i]);

    }

}

但是 Guildmember 类只检查运行命令的服务器上的用户 ID.我不知道这是否可能，而且我在文档中找不到任何可以帮助我的东西.

But the Guildmember class only checks the user's id on the server where the command is run. I don't know if it's possible, and I don't find anything that could help me in the documentation.

推荐答案

很有可能...

我们可以使用 Collector#filter 方法，因为我们想要过滤 bot 和作者所在的公会.

We can use the Collector#filter method for this since we would want to filter the guild(s) the bot and the author is.

const mutualGuilds = client.guilds.cache.filter((guild) => {
   return guild.members.cache.has(message.author.id);
});

    // This will log the mutual guild(s) the bot and the author is in, of course you can change it however you'd like.
console.log(mutualGuilds);

就这么简单.
