can't work in the win service

[jinmao88]

in the win ,normal exe ,is work good but in the win service is not work same code can't read and watch

[changkun]

Can you provide a reproducible code?

[jinmao88]

func WatchClipboard(ctx context.Context) {

err := clipboard.Init()
if err != nil {
	logger.Error(ctx, err)
	return
}
logger.Print(ctx, "新开始监听")

ch := clipboard.Watch(ctx, clipboard.FmtText)
for data := range ch {
	// print out clipboard data whenever it is changed
	//println(string(data))
	s := string(data)
	logger.Print(ctx, s)
	if s != "" {
		checkTxt(s)
		logger.Print(ctx, s)
	}
}

}

build exe ，and run in the win service

run in the win service

github.com/kardianos/service

use the demo

I dont' know how to run your code, but it looks to me that your desired case is very similar to this application: https://github.com/changkun/midgard, which was tested on window as a service.

[jinmao88]

package main

import (
	"context"
	"flag"
	"github.com/gogf/gf/v2/container/garray"
	"github.com/gogf/gf/v2/os/gctx"
	"github.com/gogf/gf/v2/os/glog"
	"github.com/takama/daemon"
	"golang.design/x/clipboard"
	"os"
)

var content = garray.New(true)

var (

	logger        = glog.New()
)

type Service struct {
	daemon.Daemon
}

// Manage by daemon commands or run the daemon
func (service *Service) Manage() (string, error) {
	ctx := gctx.New()

	// If received any kind of command, do it
	if len(os.Args) > 1 {
		logger.Print(ctx, "参数", os.Args[1])
		command := os.Args[1]
		switch command {
		case "install":
			return service.Install()
		case "remove":
			return service.Remove()
		case "start":
			return service.Start()
		case "stop":
			// No need to explicitly stop cron since job will be killed
			return service.Stop()
		case "status":
			return service.Status()
		default:
			return "", nil
		}
	}
	// Set up channel on which to send signal notifications.
	// We must use a buffered channel or risk missing the signal
	// if we're not ready to receive when the signal is sent.
	p := &program{}

	return service.Run(p)
}

type program struct{}

func (p *program) Start() {
	// Start should not block. Do the actual work async.
	go p.Run()
}
func (p *program) Run() {
	ctx := gctx.New()
	logger.SetPath(`C:\run\log`)
	logger.Print(ctx, "启动")
	//interrupt := make(chan os.Signal, 1)
	//signal.Notify(interrupt, os.Interrupt, os.Kill, syscall.SIGTERM)

	go func() {
		WatchClipboard(ctx)
	}()


}
func (p *program) Stop() {
	// Stop should not block. Return with a few seconds.

}

func main() {
	flag.Parse()
	//v1, v2, v3 = GetSystemVersion()
	//
	ctx := gctx.New()
	logger.SetPath(`C:\run\log`)


	name := "GoDaemonService1"

	srv, err := daemon.New(name, name, daemon.SystemDaemon)
	if err != nil {
		logger.Error(ctx, err)
		os.Exit(1)
	}

	service := &Service{srv}
	status, err := service.Manage()
	if err != nil {
		logger.Error(ctx, err)
		os.Exit(1)
	}

	logger.Print(ctx, status)

}





func WatchClipboard(ctx context.Context) {

	err := clipboard.Init()
	if err != nil {
		logger.Error(ctx, err)
		return
	}
	logger.Print(ctx, "新开始监听")

	textCh := clipboard.Watch(ctx, clipboard.FmtText)
	for {
		select {
		case <-ctx.Done():
			return
		case text, ok := <-textCh:
			if !ok {
				return
			}

			logger.Print(ctx, string(text), 123)

		}
	

	}
}

this my code ，run in the service ，the clipboard.watch not work
