Will this be OK?
func ListenAndServe(ctx context.Context, srv *http.Server) error {
ctx,cancel := context.WitchCancel(ctx)
wg := sync.WaitGroup{}
defer wg.Wait()
wg.Add(1)
go func(ctx context.Context) {
defer cancel()
err := srv.ListenAndServe()
fmt.Println("Server err is", err)
}(ctx)
select {
case <-ctx.Done():
srv.Close()
}
return ctx.Err()
}
When the http server error and quit, it will call the cancel to unblock the
select.
When the ctx is cancelled, it will call svr.Close() to unblock the server.
Does it works?
