go - How to multiply duration by integer?

Question

asked Oct 24, 2021 in Technique[技术] by 深蓝 (71.8m points)

To test concurrent goroutines, I added a line to a function to make it take a random time to return (up to one second)

time.Sleep(rand.Int31n(1000) * time.Millisecond)

However when I compiled, I got this error

.crawler.go:49: invalid operation: rand.Int31n(1000) * time.Millisecond (mismatched types int32 and time.Duration)

Any ideas? How can I multiply a duration?
