让 Discord bot 命令不区分大小写？

Question

我为我的 discord 机器人创建了一个 "roleinfo" 命令。我不确定如何使角色搜索不区分大小写。请参阅下面的代码：

const Discord = require("discord.js");

module.exports.run = async (bot, message, args) => {

    //Message checks
    if (!args[0]) return message.channel.send("You must specify a role name");

    //Grab args and specify as rolename
    let roleName = `${args[0]}`

    //@rolename
    let roleMention = message.guild.roles.find(roles => roles.name === roleName)

    let rolefind = message.guild.roles.find(roles => roles.name === roleName)
    if (!rolefind) return message.channel.send(`Can't find role ${args[0]}`);

    //Filter members for role
    let membersWithRole = message.guild.members.filter(member => {
        return member.roles.find(roles => roles.name === roleName);
    }).map(member => {
        return member.user.username;
    })

    let serverembed = new Discord.RichEmbed()
        .setColor("#FFD700")
        .addField("Role name", roleMention)
        .addField("Number of users with the role", rolefind.members.size)
        .addField("Users with the role", membersWithRole.join("\n"))


    message.channel.send(serverembed);
}

module.exports.help = {
    name: "roleinfo",
    usage: "``prefix`` roleinfo or ``prefix`` roleinfo rolename",
    description: "Displays detailed role information",
}

我知道我必须使用 .toLowerCase() 或 .toUpperCase() 但我不确定 how/where 在这种情况下。谁能帮帮我？将不胜感激。提前致谢！

Answer 1

照你自己说的去做

roleMention = message.guild.roles.find(roles => roles.name.toLowerCase() === roleName.toLowerCase())

那将是：

'Role-name' === 'Role-NAME'

'role-name' === 'role-name'

Answer 2

使用 .toLowerCase() 或 .toUpperCase() 会产生有关特殊 Unicode 字符的问题。

所以，使用：String.prototype.localeCompare() https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/localeCompare

对于更改，您只需编辑委托 roles => roles.name === roleName

Answer 3

也许这样的事情对你有用？（干编码，YMMV。）

想法是在全局角色列表和每个成员角色列表中的两个查看角色名称的过滤语句中使用 .toLowerCase()。

module.exports.run = async (bot, message, args) => {
  const roleName = args[0];
  //Message checks
  if (!roleName) return message.channel.send("You must specify a role name");

  const roleFind = message.guild.roles.find(roles => roles.name.toLowerCase() === roleName.toLowerCase());
  if (!roleFind) return message.channel.send(`Can't find role ${roleName}`);

  const memberNamesWithRole = [];
  message.guild.members.forEach(member => {
    if (member.roles.some(memberRole => memberRole.name.toLowerCase() === roleName.toLowerCase())) {
      memberNamesWithRole.push(member.user.username);
    }
  });

  const serverembed = new Discord.RichEmbed()
    .setColor("#FFD700")
    .addField("Role name", roleName)
    .addField("Number of users with the role", memberNamesWithRole.length)
    .addField("Users with the role", memberNamesWithRole.join("\n"));

  message.channel.send(serverembed);
};

让 Discord bot 命令不区分大小写？

Making Discord bot command case insensitive?

javascript

node.js

discord.js

case-sensitive
