I need to read data from the Go channel for a certain period of time (say 5 seconds). The select statement with timeout doesn't work for me, as I need to read as many values as available and stop exactly after 5 seconds. So far, I've come up with a solution using an extra time channel https://play.golang.org/p/yev9CcvzRIL
package main
import "time"
import "fmt"
func main() {
// I have no control over dataChan
dataChan := make(chan string)
// this is a stub to demonstrate some data coming from dataChan
go func() {
for {
dataChan <- "some data"
time.Sleep(time.Second)
}
}()
// the following is the code I'm asking about
timeChan := time.NewTimer(time.Second * 5).C
for {
select {
case d := <-dataChan:
fmt.Println("Got:", d)
case <-timeChan:
fmt.Println("Time's up!")
return
}
}
}
I'm wondering is there any better or more idiomatic way for solving this problem?
