通过 ID discord.js 添加对消息的反应

Question

I would like to add a reaction to a message by message ID. For example, messageID.react('') . Is there a way to do that?

Answer 1

messages.fetch() returns a promise. So in order to react to the message fetched, you can do it in two ways.

Using .then() :

channel.messages.fetch(msg).then(m => {
    m.react("👍");
});

Using await :

const m = await channel.messages.fetch(msg);
m.react("👍");

Answer 2

You need to have the text channel the message is sent in, then you can just do:

channel.messages.fetch(messageId).react("👍");

Answer 3

Found the answere:

channelID.messages.fetch(MESSAGE_ID).then(function (message) { message.react("") })
