trying to get status codes from different sites concurrently, but getting a deadlock error. not sure what the issue is
@JustinObanor, I added a
fmt.Printf before the loop and see the first
sites is empty. That means you’re adding 6 to the wait group and calling
Done only 5 times. I recommend this inatead: https://play.golang.org/p/l9ut4uQ6W1L
You can also filter out empty strings in your slice before iterating, like this https://play.golang.org/p/RcTQomu2j7d (1)
It’s still recommended to add to the WaitGroup as skillian does.
(1) For reasons unknown my example doesn’t work on the playgroup but works locally with go version go1.14 windows/amd64.
Thanks. It doesn’t work on playground because all internet requests are banned there. It works locally as you said
