Discord.js：从所有通道获取消息

Question

message.channel.messages.fetch does fine at fetching from the channel the command is run in, but I need to be able to fetch messages from ANY channel in the server. For reference, I'm making a command to quote a message via message ID, but as of right now it can only quote messages from the same channel that the command is run in.

Answer 1

Loop through every channel and fetch messages in them.

message.guild.channels.cache.forEach(channel => {
  channel.messages.fetch().then(messages => {
    messages.forEach(msg => console.log(msg.content));
  });
});

This example fetches as many messages as possible from every channel in the server and logs the content of each one. You could use an if statement to check if the message content is the specified quote to look for.

MessageManager.fetch()

Answer 2

let found; message.guild.channels.cache.each(channel => { if(found) return; found = await channel.messages.fetch("ID_HERE").catch(() => undefined); });
