}

2 注册windows服务

2.1cmd操作windows服务

而我们启动一般的exe文件却要先登陆Windows后才能启动它,通常还有一个用户界面命令行或者是GUI界面,通常由用户手动启动和停止。

  1. 注册服务
# 注册一个ServiceTest服务
sc create ServiceTest binpath="/path/to/exe"
  1. 启动服务
sc start ServiceTest
  1. 停止、删除服务
sc stop ServiceTest
sc delete ServiceTest

2.2 golang注册windows服务

package main

import (
	"fmt"
	"github.com/kardianos/service"
	"os"
)


func main() {
	srvConfig := &service.Config{
		Name:        "MyGoService",
		DisplayName: "MyGoService服务",
		Description: "this is a service about go",
	}
	prg := &program{}
	s, err := service.New(prg, srvConfig)
	if err != nil {
		fmt.Println(err)
	}
	if len(os.Args) > 1 {
		serviceAction := os.Args[1]
		switch serviceAction {
		case "install":
			err := s.Install()
			if err != nil {
				fmt.Println("安装服务失败: ", err.Error())
			} else {
				fmt.Println("安装服务成功")
			}
			return
		case "uninstall":
			err := s.Uninstall()
			if err != nil {
				fmt.Println("卸载服务失败: ", err.Error())
			} else {
				fmt.Println("卸载服务成功")
			}
			return
		case "start":
			err := s.Start()
			if err != nil {
				fmt.Println("运行服务失败: ", err.Error())
			} else {
				fmt.Println("运行服务成功")
			}
			return
		case "stop":
			err := s.Stop()
			if err != nil {
				fmt.Println("停止服务失败: ", err.Error())
			} else {
				fmt.Println("停止服务成功")
			}
			return
		}
	}

	err = s.Run()
	if err != nil {
		fmt.Println(err)
	}
}

type program struct{}

func (p *program) Start(s service.Service) error {
	fmt.Println("服务运行...")
	go p.run()
	return nil
}
func (p *program) run() {
	// 具体的服务实现
}
func (p *program) Stop(s service.Service) error {
	return nil
}

添加上启动参数

package main

import (
	"fmt"
	"github.com/kardianos/service"
	"log"
	"os"
	"time"
)

// Program 结构定义了实现Service接口所需的方法
type Program struct {
	exit chan struct{}
}

// Start 是在service.Start方法调用时被自动调用的方法
// 在启动服务时执行具体的业务代码
func (p *Program) Start(s service.Service) error {
	go p.run()
	return nil
}

// Stop 是在service.Stop方法调用时被自动调用的方法
func (p *Program) Stop(s service.Service) error {
	close(p.exit)
	return nil
}

func main() {
	// 创建一个ServiceConfig对象用于描述服务的配置信息
	svcConfig := &service.Config{
		Name:        "MyService",
		DisplayName: "MyService",
		Description: "This is a service for Guard.",
		Arguments:   []string{"run"},
		Option: service.KeyValue{
			"StartType":              "automatic",
			"OnFailure":              service.OnFailureRestart,
			"OnFailureDelayDuration": "1m",
			"OnFailureResetPeriod":   10,
		},
	}

	// 创建一个Program对象
	prog := &Program{exit: make(chan struct{})}

	// 将Program对象与ServiceConfig对象绑定,并创建一个新的Service对象
	s, err := service.New(prog, svcConfig)
	if err != nil {
		log.Fatal(err)
	}

	// 如果命令参数为install、start、stop或restart,则执行对应的操作
	// 如果没有命令参数,则输出命令行帮助信息
	switch os.Args[1] {
	case "install":
		err = s.Install()
		if err != nil {
			log.Fatal(err)
		}
		log.Printf("Service %s installed.", s.String())
	case "start":
		err = s.Start()
		if err != nil {
			log.Fatal(err)
		}
		log.Printf("Service %s started.", s.String())
	case "stop":
		err = s.Stop()
		if err != nil {
			log.Fatal(err)
		}
		log.Printf("Service %s stopped.", s.String())
	case "uninstall":
		err = s.Uninstall()
		if err != nil {
			log.Fatal(err)
		}
		log.Printf("Service %s uninstall.", s.String())
	case "run":
		err = s.Run()
		if err != nil {
			log.Fatal(err)
		}
		log.Printf("Service %s run.", s.String())
	case "restart":
		err = s.Stop()
		if err != nil {
			log.Fatal(err)
		}
		log.Printf("Service %s stopped.", s.String())
		err = s.Start()
		if err != nil {
			log.Fatal(err)
		}
		log.Printf("Service %s started.", s.String())
	default:
		log.Printf("Usage: %s install|uninstall|start|stop|restart", os.Args[0])
	}
}

func (p *Program) run() {
	file, err := os.OpenFile("E:\Go\GoPro\src\go_code\work\ziyi-Guard\log.txt", os.O_WRONLY|os.O_RDONLY, os.ModePerm)
	defer file.Close()
	if err != nil {
		log.Println("open file err=", err)
		return
	}
	for {
		time.Sleep(time.Second * 5)
		file.WriteString(fmt.Sprintf(time.Now().String()) + " hellon")
	}
}

2.3 检测服务是否存在

windows
package main

import (
	"fmt"
	"os/exec"
	"strings"
)

func main() {
	var serviceName string
	fmt.Println("please enter the serviceName you want to check:")
	fmt.Scanln(&serviceName)
	// 判断AJRouter服务是否启动
	cmd := exec.Command("sc", "query", serviceName)
	cmdOutput, err := cmd.Output()
	if err != nil {
		fmt.Printf("%v is not installedn", serviceName)
		return
	} else {
		fmt.Printf("%v is installedn", serviceName)
	}
	if strings.Contains(string(cmdOutput), "RUNNING") {
		fmt.Printf("%v is runningn", serviceName)
	} else if strings.Contains(string(cmdOutput), "STOPPED") {
		fmt.Printf("%v is stoppedn", serviceName)
	}
}

linux
package main

import (
	"bytes"
	"fmt"
	"os/exec"
)

func main() {
	// 判断sshd是否存在
	cmd := exec.Command("which", "sshd")
	err := cmd.Run()
	if err != nil {
		fmt.Println("sshd not found")
		return
	}

	// 判断sshd服务是否启动
	cmd = exec.Command("systemctl", "status", "sshd")
	var out bytes.Buffer
	cmd.Stdout = &out
	err = cmd.Run()
	if err != nil {
		fmt.Println("failed to check sshd status:", err)
		return
	}
	if out.String() == "" {
		fmt.Println("sshd is not running")
	} else {
		fmt.Println("sshd is running")
	}
}

mac
package main

import (
	"bytes"
	"fmt"
	"os/exec"
)

func main() {
	// 判断sshd服务是否存在
	cmd := exec.Command("launchctl", "list", "ssh")
	var out bytes.Buffer
	cmd.Stdout = &out
	err := cmd.Run()
	if err != nil {
		fmt.Println("failed to check sshd service:", err)
		return
	}
	if out.String() != "" {
		fmt.Println("sshd service is installed")
	} else {
		fmt.Println("sshd service is not installed")
	}

	// 判断sshd服务是否启动
	cmd = exec.Command("launchctl", "list", "ssh")
	cmdOutput, err := cmd.Output()
	if err != nil {
		fmt.Println("failed to check sshd service:", err)
		return
	}
	statusStr := "statust"
	if bytes.Contains(cmdOutput, []byte(statusStr+"0")) {
		fmt.Println("sshd service is stopped")
	} else if bytes.Contains(cmdOutput, []byte(statusStr+"1")) {
		fmt.Println("sshd service is running")
	} else {
		fmt.Println("failed to get sshd service status")
	}
}

3 tips

3.1去掉.exe运行的黑窗口

go build -ldflags "-s -w -H=windowsgui"
 
-s 省略符号表和调试信息
-w Omit the DWARF symbol table 省略DWARF符号表
-H windowsgui  不打印信息到console (On Windows, -H windowsgui writes a "GUI binary" instead of a "console binary."),就不会有cmd窗口

3.2让exe程序管理员身份运行(获取UAC)

windows上执行有关系统设置命令的时候需要管理员权限才能操作比如修改网卡的禁用、启用状态双击执行是不能正确执行命令的,只有右键管理员身份运行才能成功。

① 不带图标
  1. 安装rsrc工具
go get github.com/akavel/rsrc
  1. nac.manifest 文件拷贝当前windows项目根目录
    nac.manifest:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
    version="9.0.0.0"
    processorArchitecture="x86"
    name="myapp.exe"
    type="win32"
/>
<description>myapp</description>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
        <requestedPrivileges>
            <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
        </requestedPrivileges>
    </security>
</trustInfo>
</assembly>
  1. 执行rsrc命令生成.syso文件
rsrc -manifest nac.manifest -o nac.syso
  1. build文件

build的时候不带任何参数,即:go build

go build

如果写成指定文件编译–go build main.go 将无法成功获取UAC。(go build编译开始时,会搜索当前目录的 go 源码以及.syso文件,最后将所有资源一起打包到EXE文件。go build main.go 这种指定文件的编译命令,会编译指定文件和指定文件里面的所需要依赖包,但是不会将.syso 文件打包到EXE。)如果,你的golang程序需要UAC权限或带GUI界面的,一定要注意正确使用编译命令!

最后目录结构:
在这里插入图片描述

② 带图标
  1. 安装rsrc

  2. 将icon.ico图标文件放在与main.go文件相同的文件夹

  3. 编写main.manifest

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity
    version="9.0.0.0"
    processorArchitecture="x86"
    name="myapp.exe"
    type="win32"
/>
<description>myapp</description>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
    <security>
        <requestedPrivileges>
            <requestedExecutionLevel level="requireAdministrator" uiAccess="false"/>
        </requestedPrivileges>
    </security>
</trustInfo>
</assembly>
  1. 运行命令,生成.syso文件
 rsrc -arch amd64 -manifest main.manifest -ico main.ico -o main.syso

需要加上arch amd64,不然回报 is incompatible with i386:x86-64 output 错误

  1. 编译打包文件
go build -ldflags "-s -w" -o xguard.exe

最后目录结构:
在这里插入图片描述

注意:如果报错的话,可能是因为没有gcc环境下载并配置即可

③运行时不展示黑窗口
go build -ldflags "-H=windowsgui" main.go
//go build -ldflags "-s -w -H=windowsgui" -o test.exe

4 go-bindata使用

有时候我们需要将静态资源打包进.exe文件中,除了go后面官方提供的embed,还可以使用第三方组件:go-bindata

4.1 安装

1. go get -u github.com/go-bindata/go-bindata/...
// 引入fs(go-bindata-assetfs:提供fs服务)
2. go get github.com/elazarl/go-bindata-assetfs/...

4.2 打包生成bindata.go

# 将assets目录下的静态资源打包生成bindata/bindata.go文件中
go-bindata -o bindata/bindata.go -pkg bindata assets/...

4.3 main.go中引用bindata.go数据

项目结构:
在这里插入图片描述

func_file.go:

package service

import (
	"bytes"
	"compress/gzip"
	"fmt"
	"github.com/aobco/log"
	"github.com/getlantern/systray"
	"net/http"
	"os"
	"os/exec"
	"path/filepath"
	"runtime"
	"ziyi.com/xguard/bindata"
)

func init() {
	// 注册静态文件处理函数
	http.HandleFunc("/", serveStaticFile)
}

// serveStaticFile 返回静态文件内容
func serveStaticFile(w http.ResponseWriter, r *http.Request) {
	// 获取文件路径
	filePath := filepath.Join(staticDir, r.URL.Path)
	log.Info("filePath:", filePath)
	// 从 bindata.go 文件中读取文件内容
	file, err := bindata.Asset(filePath)
	if err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
		return
	}

	// 设置 Content-Type
	contentType := "text/html"
	if filepath.Ext(filePath) == ".css" {
		contentType = "text/css"
	} else if filepath.Ext(filePath) == ".js" {
		contentType = "application/javascript"
	}
	w.Header().Set("Content-Type", contentType)

	// 返回静态文件内容
	fmt.Fprint(w, string(file))
}
# 编译
go build main.go
