I'm create program by golang like the picture above.
At first, we go through the authentication process and then main logic.
In main logic, I apply cron to execute it repeatedly.
problem is when http connection has lost.
If the http connection is lost in send data, I want to run the ping module and restart it from the first authentication.
Currently, I apply panic and recovery function and then recursive main().
Do you have a better idea?
package main
import (
"github.com/jasonlvhit/gocron"
"fmt"
"time"
)
var c = gocron.NewScheduler()
func authentication() bool {
fmt.Println("1.authentication")
return true
}
func collectData() {
fmt.Println("2.collectData")
}
func sendData() bool {
fmt.Println("3.sendData")
return false
}
func mainLogic(){
defer func() {
if r := recover(); r != nil {
fmt.Println("recovery")
main() ==> when ping result is success, I cause panic and then recursive call main() to restart from authentication.
}
}()
collectData()
if !sendData(){
if ping(true) {
c.Clear() // stop exist process of cron
panic("ping sucess")
}
}
}
func ping(pingResult bool) bool {
if pingResult {
fmt.Println("4.ping : true")
return pingResult
} else {
fmt.Println("4.ping : failed => retry after 3sec")
time.Sleep(3000000000)
ping(pingResult)
}
return pingResult
}
func main() {
c = gocron.NewScheduler()
if authentication() {
c.Every(5).Seconds().Do(mainLogic)
<-c.Start()
}
}
