Hi,
we are using this lib to do long polling for our REST API, but we facing issue when sending data to our API, it seems the channel not blocked and not waits till data written to a variable, so we don't know when it's finished or not, please check following code for details:
for {
datach, err := c.pollChannel.Get(poll.PollTime) // this line will get data from longpoll
if err != nil {
break
}
rows := <-datach // get data from channel
logrus.Debugf("from poll channel: %d", rows) // this debug will print data from channel (data exists)
if (rows != nil){
// processing the data and pass it to API
}
}
// return data empty to API
// in our case, we always got empty data even though debug prints the data to console.
our question: Is there any Flag to check the go routine / channel are done? so, we can tells API to waits and response if data ready.
