control is a automation tool written from scratch using golang on top of Chrome DevTools
Warning This is an experimental project, backward compatibility is not guaranteed!
go get -u github.com/ecwid/control
Here is an example of using:
func main() { session, cancel, err := control.Take("--no-startup-window") if err != nil { panic(err) } defer cancel() retrier := retry.Static{ Timeout: 10 * time.Second, Delay: 500 * time.Millisecond, // delay between attempts } session.Frame.MustNavigate("https://zoid.ecwid.com") var products []string err = retry.Func(retrier, func() error { products = []string{} return session.Frame.QueryAll(".grid-product__title-inner").Then(func(nl control.NodeList) error { return nl.Foreach(func(n *control.Node) error { return n.GetText().Then(func(s string) error { products = append(products, s) return nil }) }) }) }) if err != nil { panic(err) } // "must way" throws panic on an error for _, node := range session.Frame.MustQueryAll(".grid-product__title-inner") { log.Println(node.MustGetText()) } }
You can call any CDP method implemented in protocol package using a session
err = security.SetIgnoreCertificateErrors(session, security.SetIgnoreCertificateErrorsArgs{ Ignore: true, })
or call a custom unimplemented method
err = session.Call("Security.setIgnoreCertificateErrors", sendStruct, receiveStruct)
Subscribe on the domain event
future := control.Subscribe(session, "Target.targetCreated", func(t target.TargetCreated) bool { return t.TargetInfo.Type == "page" }) defer future.Cancel() // do something here ... ctx, cancel := context.WithTimeout(context.TODO(), time.Second*10) result /* target.TargetCreated */, err := future.Get(ctx)
