問題描述
有沒有辦法讓機器人在繼續代碼之前等待一段時間(例如 5 秒)?我需要類似的東西:
Is there any way to make a bot wait for some time (for example 5 seconds) before continuing the code? I need something like:
client.on('messageCreate', message => {
message.channel.send('1st message')
wait(5000)
message.channel.send('2nd message')
wait(5000)
message.channel.send('3rd message')
})
我嘗試使用 setInterval，就像許多人建議的那樣，但這似乎不是我的解決方案.我也不能使用 await setTimeout(time) 因為 SyntaxError: await 僅在異步函數和模塊的頂層主體中有效 和 TypeError [ERR_INVALID_CALLBACK]:回調必須是一個函數.收到5000
I tried using setInterval, like many people suggest, but that doesn't seem to be a solution for me.
Also I can't use await setTimeout(time) because of SyntaxError: await is only valid in async functions and the top level bodies of modules and TypeError [ERR_INVALID_CALLBACK]: Callback must be a function. Received 5000
推薦答案
你可以promisify setTimeout 與 Node 的 Util 庫.然后使 messageCreate 回調異步.
You can promisify setTimeout with Node's Util library. Then make the messageCreate callback asynchronous.
const wait = require('util').promisify(setTimeout);
client.on('messageCreate', async message => {
message.channel.send('1st message')
await wait(5000)
message.channel.send('2nd message')
await wait(5000)
message.channel.send('3rd message')
})
