点击此反应表情符号DIscord.js时是否可以删除消息

Question

如何修复此问题？我想在用户点击反应X 时删除消息

client.on('message', async message => {
if (message.channel.id === emojiChannelID) {
try {
await message.react('✅');
await message.react('✖');
} catch(err) {
console.error(err);
}
}
});```

Answer 1

discord.js中有一个message.awaitReaction()，它将返回用户的反应

// Filter for only
const filter = function(reaction, user) { 
return reaction.emoji.name === '✅' || reaction.emoji.name === '✖';
}
// {...}
let reactionMessage = await message.react('✅');
// Make sure to set max: 1 so that the promise returns after the first reaction
let reactionCollection = await reactionMessage.awaitReactions(filter, { max: 1});
// reactionCollection is a Collection<string, MessageReaction>
// Use first() to get the first (and only)
let reaction = reactionCollection.first();

Kian在这里，

这个代码应该适用于您，如果你愿意，我可以浏览并解释每一行：)

祝你今天愉快，酋长！

async function emojiMessage(message, validReactions) {
for (const reaction of validReactions) await message.react(reaction);
const filter = (reaction, user) => validReactions.includes(reaction.emoji.name) && (!user.bot)
return message
.awaitReactions(filter, {
max: 1,
time: 42000
})
.then(collected => collected.first() && collected.first().emoji.name);
}
async function deleteMessage(message) {
const emoji = await emojiMessage(message, ["✅", "❌"]);
console.log(emoji)
// if the emoji is a tick:
if (emoji === "✅") {
// delete their message
console.log("tick")
if (message.deletable == true) {
console.log("can delete")
console.log("attempting to delete")
message.delete()
}
if (!message.deletable == false) {
"cannot delete"
}
} else if (emoji === "❌") { // if the emoji is a cross
/*
*  do something else
*/
return;
}
}

client.on('message', message => {
if (message.channel.id === emojiChannelID) {
// runs the function
deleteMessage(message)
}
/*
* do something else
*/
})

示例用法：

const m = await message.channel.send('hi!');
reactionDelete(m, message, 20000); // assuming 'message' is the actual sent message

async function reactionDelete (botMessage, playerMessage, timeout) {
const filter = (reaction, user) => {
return ['  ️'].includes(reaction.emoji.name) && user.id === playerMessage.author.id;
};
botMessage.react('  ️');
botMessage.awaitReactions(filter, { max: 1, time: timeout})
.then(collected => {
const reaction = collected.first();
if (reaction.emoji.name === '  ️') {
botMessage.delete();
}
})
.catch(collected => {
if (botMessage.deletable) botMessage.reactions.removeAll();
});
};
