discord.js v12：如何在 DM 頻道中等待消息？

Question

這是我嘗試過的代碼：

message.author.dmChannel.awaitMessages(msg => {
    console.log(msg.content)
});

但它返回此錯誤消息：

TypeError: Cannot read property 'awaitMessages' of null

更新代碼：

message.author.send("What is your name?")

const filter = m => m.author.id === message.author.id

message.author.dmChannel.awaitMessages(filter)
     .then((collected) => console.log(collected.first().content))

Answer 1

您沒有正確使用awaitMessages() ，您需要通過一個filter

const filter = (m) => m.author.id === message.author.id
message.author.dmChannel.awaitMessages(filter)
  .then((collected) => console.log(collected.first().content))

Answer 2

您應該先嘗試創建一個 DM 頻道：

let channel = message.author.dmChannel;
if (!channel) channel = await message.author.createDM();

請注意，createDM() 返回一個 Promise，這將要求您將命令切換到異步 function（如果它已經不是）
