如何使用 Discord.js 列出角色中的成员.

How I can list members in a role using Discord.js.

我的代码:

client.on("message", message => {
    var guild = message.guild;
    let args = message.content.split(" ").slice(1);
    if (!message.content.startsWith(prefix)) return;
    if (message.author.bot) return; 
    if(message.content.startsWith(prefix + 'go4-add')) {
        guild.member(message.mentions.users.first()).addRole('415665311828803584');                     
    }
});

我将如何在嵌入中列出所有具有 go4 角色的成员.当在频道中输入消息 .go4-list 时，我希望机器人通过嵌入响应.

How would I go about listing all the members that have the go4 role in an embed. When the message .go4-list is entered in a channel I would like the bot to respond with the embed.

推荐答案

<Role>.members 返回一个 GuildMember 的 rel="noreferrer">集合s.只需映射此集合即可获得所需的属性.

<Role>.members returns a collection of GuildMembers. Simply map this collection to get the property you want.

根据您的情况，这是一个示例:

Here's an example according to your scenario:

message.guild.roles.get('415665311828803584').members.map(m=>m.user.tag);

这将从具有go4"角色的成员中输出一组用户标签.现在您可以.join(...) 将此数组转换为您想要的格式.

This will output an array of user tags from members that have the "go4" role. Now you can .join(...) this array to your desired format.

另外，guild.member(message.mentions.users.first()).addRole('415665311828803584'); 可以缩短为:message.mentions.members.first().addRole('415665311828803584');

下面是一个粗略的示例，说明结果如何:

Here's a rough example of how it would look as a result:

client.on("message", message => {

    if(message.content.startsWith(`${prefix}go4-add`)) {
        message.mentions.members.first().addRole('415665311828803584'); // gets the <GuildMember> from a mention and then adds the role to that member                     
    }

    if(message.content == `${prefix}go4-list`) {
        const ListEmbed = new Discord.RichEmbed()
            .setTitle('Users with the go4 role:')
            .setDescription(message.guild.roles.get('415665311828803584').members.map(m=>m.user.tag).join('
'));
        message.channel.send(ListEmbed);                    
    }
});

正如@Wright 在他的回答中提到的那样，如果成员过多，则会引发错误，因为嵌入最多只能容纳 2048 个字符，因此您可能需要在发送嵌入之前进行一些检查，然后处理超大嵌入通过将它们拆分为多个嵌入消息，或者使用基于反应的页面.

As @Wright mentioned in his answer, if there are over many members it will throw an error as an embed can only hold 2048 characters maximum, so you may want to do some checks before sending out the embed and then handle oversized embeds by either splitting them into multiple embed messages, or using reaction based pages maybe.
