Original GitHub issue: https://github.com/fatedier/frp/issues/2712

Describe the feature request

Currently to integrate the functionality of the frp to another package we have to integrate the .exe file. Can we use the frp package directly to integrate it. I have requested this feature before as well for version 0.37.1 ( related issue #2516 )

Describe alternatives you've considered

func runClient(cfgFilePath string) error {
	cfg, pxyCfgs, visitorCfgs, err := config.ParseClientConfig(cfgFilePath)
	if err != nil {
		return err
	}
	return startService(cfg, pxyCfgs, visitorCfgs, cfgFilePath)
}

func startService(
	cfg config.ClientCommonConf,
	pxyCfgs map[string]config.ProxyConf,
	visitorCfgs map[string]config.VisitorConf,
	cfgFile string,
) (err error) {

	log.InitLog(cfg.LogWay, cfg.LogFile, cfg.LogLevel,
		cfg.LogMaxDays, cfg.DisableLogColor)

	if cfg.DNSServer != "" {
		s := cfg.DNSServer
		if !strings.Contains(s, ":") {
			s += ":53"
		}
		// Change default dns server for frpc
		net.DefaultResolver = &net.Resolver{
			PreferGo: true,
			Dial: func(ctx context.Context, network, address string) (net.Conn, error) {
				return net.Dial("udp", s)
			},
		}
	}
	svr, errRet := client.NewService(cfg, pxyCfgs, visitorCfgs, cfgFile)
	if errRet != nil {
		logrus.Errorln(err)
		return
	}
	err = svr.Run()
	if err != nil {
		logrus.Errorln("unable to start client: ", err)
	}
	return
}

Something like this, this is the code snippet picked from the frp client but it doesn't work it gives the error like:

@fatedier Please let me know if I can help with this in any possible way, as I would really like this feature to be there with frp. I will be happy to help and contribute.
Thanks!

read error: message type error

From this log, i guess your server version is not compatible with your client.

[common]

[web]
type = http
local_port = 8090
custom_domains = 
use_compression = true

For the reference above is my cfg file. @fatedier
It will be really helpful if you could please guide here

It's not releated to your configures. This error means received message type is not registered in github.com/fatedier/frp/pkg/msg/msg.go.

I can't help you without any debugging method or full codes.
