如何使用自定义表情符号添加反应角色功能?

Question

Stack Overflow社区的各位成员们，大家好，

我一直在研究一个功能，当版主批准使用 Auttaja 的网守用户时，该功能就会激活。基本上，新用户可以在两个服务器表情符号反应之间进行选择，这将为他/她提供角色。但是我一直在角色和表情符号常量方面遇到困难。

这是我的代码：

const ApprovalEmbed = new Discord.MessageEmbed()
.setColor('RED')
.setTitle('Hi there new user!')
.setDescription('Please react to this message with either one of the emojis in order to get a role.')
.addFields(
{ name: 'u200B', value: 'u200B' },
{ name: 'The Boomer emoji gives you the "Les boomers normaux" role, and the rat emoji gives you the "The normal Rat Haven dwellers" role.'},
{ name: 'u200B', value: 'u200B' },
{ name: 'Selecting the Boomer emoji will give you access to only the Boomer Haven compartment, and the rat emoji will give you access to the Rat Haven compartment. '},
{ name: 'u200B', value: 'u200B' },
{name: 'To get access to both of these compartments, please consider using the command "^AccessToBoth" to receive the "Access to both compartments" role.'},
)
.setTimestamp()
.setFooter('Time to pick a role!');
const roleOne = guild.roles.cache.find((role) => role.name === "The normal Rat Haven dwellers")
const roleTwo = guild.roles.cache.find((role) => role.name === "Les boomers normaux")
const BoomerEmoji = message.guild.emojis.cache.find(emoji => emoji.name === 'boomer');
const RatEmoji = message.guild.emojis.cache.find(emoji => emoji.name === 'robincutmoment');

client.on('message', async message => {
let AdminRole = message.member.roles.cache.find(role => role.name === "Server Moderators")
let RulerRole = message.member.roles.cache.find(role => role.name === "The Supreme Boomers")
let RatRole = message.member.roles.cache.find(role => role.name === "Rat Majesty Robin")
if (message.member.roles.cache.has(AdminRole)) {
} else if (message.member.roles.cache.has(RulerRole)) {
} else if (message.member.roles.cache.has(RatRole)) {}
if (message.content === `-approve`) {
message.channel.send(BoomerEmoji)
const reactionMessage = await message.channel.send(ApprovalEmbed);
message.channel.send(ApprovalEmbed).then(reactionMessage.react(BoomerEmoji), reactionMessage.react(RatEmoji))


}
const filter = (reaction, user) => {
return [(BoomerEmoji), (RatEmoji)].includes(reaction.emoji.name) && user.id === message.author.id;
};
message.awaitReactions(filter, { max: 1, time: 60000, errors: ['time'] })
.then(collected => {
const reaction = collected.first();

if (reaction.emoji.name === (BoomerEmoji)) {
message.member.roles.add(roleOne)
} else if (reaction.emoji.name === (RatEmoji)) {
message.member.roles.add(roleTwo)
}
})

});

您的第一个问题发生在以下代码段中：

if (message.member.roles.cache.has(AdminRole)) {
// ...
} else if (message.member.roles.cache.has(RulerRole)) {
// ...
} else if (message.member.roles.cache.has(RatRole)) {
// ...
}

Collection.prototype.has()检查集合中是否存在元素。它需要一个参数：您希望检查其是否存在的元素的键。由于角色是由雪花映射的，因此应传递角色 ID，而不是整个对象。

// `Collection.prototype.has()` is identical to `Map.prototype.has()`
// here's how it works:
const map = new Map();
// 'foo' is the key,
// 'bar' is the value
map.set('foo', 'bar');
console.log(map.has('foo')); // true
console.log(map.has('bar')); // 'bar' is not the key; false

if (message.member.roles.cache.has(AdminRole.id)) {
// ...
} else if (message.member.roles.cache.has(RulerRole.id)) {
// ...
} else if (message.member.roles.cache.has(RatRole.id)) {
// ...
}

如果你想花哨，你可以用Collection.prototype.findKey()代替普通的Collection.prototype.find()。此方法几乎相同，只是它返回找到的元素的键而不是值。同样，它几乎没有区别;只是另一种选择。

let AdminRole = message.member.roles.cache.findKey(
(role) => role.name === 'Server Moderators'
);
let RulerRole = message.member.roles.cache.findKey(
(role) => role.name === 'The Supreme Boomers'
);
let RatRole = message.member.roles.cache.findKey(
(role) => role.name === 'Rat Majesty Robin'
);
if (message.member.roles.cache.has(AdminRole)) {
// ...
} else if (message.member.roles.cache.has(RulerRole)) {
// ...
} else if (message.member.roles.cache.has(RatRole)) {
// ...
}

你的第二个问题有点类似。BoomerEmoji和RatEmoji是完整的GuildEmoji对象。但是，在这一行中：

return (
[BoomerEmoji, RatEmoji].includes(reaction.emoji.name) &&
user.id === message.author.id
);

还有这些行：

if (reaction.emoji.name === BoomerEmoji) {
message.member.roles.add(roleOne);
} else if (reaction.emoji.name === RatEmoji) {
message.member.roles.add(roleTwo);
}

您正在将其与另一个表情符号的名称属性进行比较。此修复程序相当简单，只需澄清声明每个变量时只需要name属性：

const BoomerEmoji = message.guild.emojis.cache.find(
(emoji) => emoji.name === 'boomer'
).name;
const RatEmoji = message.guild.emojis.cache.find(
(emoji) => emoji.name === 'robincutmoment'
).name;
