golang open Downloads folder explorer window on Windows 10 not working

问题

我可以使用Windows 10的cmd打开资源管理器窗口。

  1. explorer C:\Users\bruce\Downloads\

所以我想在Go中执行这个命令，但它打开的是“文档”文件夹而不是“下载”文件夹，我该如何解决这个问题？

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"os"
  6. 	"os/exec"
  7. 	"runtime"
  8. )
  10. func main() {
  11. 	homeDir, _ := os.UserHomeDir()
  13. 	if runtime.GOOS == "darwin" {
  14. 		downloadDir := homeDir + "/Downloads/"
  15. 		cmd := `open "` + downloadDir + `"`
  16. 		exec.Command("/bin/bash", "-c", cmd).Output()
  17. 	} else {
  18. 		downloadDir := homeDir + "\\Downloads\\"
  19. 		cmd := `explorer ` + downloadDir
  20. 		fmt.Println("cmd: ", cmd)
  21. 		exec.Command("cmd", "/C", cmd).Output()
  22. 	}
  23. }

I can open a explorer window using on Windows 10 cmd

  1. explorer C:\Users\bruce\Downloads\

So I'm thinking executing this command in go, but it opens Documents folder instead of Downloads folder, how can I solve this issue

  1. package main
  3. import (
  4. 	"fmt"
  5. 	"os"
  6. 	"os/exec"
  7. 	"runtime"
  8. )
  10. func main() {
  11. 	homeDir, _ := os.UserHomeDir()
  13. 	if runtime.GOOS == "darwin" {
  14. 		downloadDir := homeDir + "/Downloads/"
  15. 		cmd := `open "` + downloadDir + `"`
  16. 		exec.Command("/bin/bash", "-c", cmd).Output()
  17. 	} else {
  18. 		downloadDir := homeDir + "\\Downloads\\"
  19. 		cmd := `explorer ` + downloadDir
  20. 		fmt.Println("cmd: ", cmd)
  21. 		exec.Command("cmd", "/C", cmd).Output()
  22. 	}
  23. }

问题解决了，原来exec.Command()的第一个参数应该使用explorer而不是cmd。

下面的代码片段是可行的：

  1. package main
  3. import (
  4. 	"os"
  5. 	"os/exec"
  6. 	"runtime"
  7. 	"strings"
  8. )
  10. func main() {
  11. 	homeDir, _ := os.UserHomeDir()
  12. 	downloadDir := homeDir + "/Downloads/"
  13. 	if runtime.GOOS == "darwin" {
  14. 		cmd := `open "` + downloadDir + `"`
  15. 		exec.Command("/bin/bash", "-c", cmd).Start()
  16. 	} else {
  17. 		downloadDir = strings.ReplaceAll(downloadDir, "/", "\\")
  18. 		exec.Command("explorer", downloadDir).Start()
  19. 	}
  20. }

更简化的版本，使用downloadDir := filepath.Join(homeDir, "Downloads")代替downloadDir = strings.ReplaceAll(downloadDir, "/", "\\")：

  1. package main
  3. import (
  4. 	"os"
  5. 	"os/exec"
  6. 	"path/filepath"
  7. 	"runtime"
  8. )
  10. func main() {
  11. 	homeDir, _ := os.UserHomeDir()
  12. 	downloadDir := filepath.Join(homeDir, "Downloads")
  13. 	if runtime.GOOS == "darwin" {
  14. 		exec.Command("open", downloadDir).Start()
  15. 	} else {
  16. 		exec.Command("explorer", downloadDir).Start()
  17. 	}
  18. }

根据@panapol-p在这里指出的内容：

  1. package main
  3. import (
  4. 	"os"
  5. 	"os/exec"
  6. 	"path/filepath"
  7. 	"runtime"
  8. )
  10. func main() {
  11. 	homeDir, _ := os.UserHomeDir()
  13. 	cmd := "open"
  14. 	downloadDir := filepath.Join(homeDir, "Downloads")
  15. 	if runtime.GOOS == "windows" {
  16. 		cmd = "explorer"
  17. 		downloadDir = "shell:downloads"
  18. 	}
  19. 	exec.Command(cmd, downloadDir).Start()
  20. }
英文:

Problem solved, turns out that the first parameter of exec.Command() should use explorer instead of cmd

The snippet below is working

  1. package main
  3. import (
  4. 	"os"
  5. 	"os/exec"
  6. 	"runtime"
  7. 	"strings"
  8. )
  10. func main() {
  11. 	homeDir, _ := os.UserHomeDir()
  12. 	downloadDir := homeDir + "/Downloads/"
  13. 	if runtime.GOOS == "darwin" {
  14. 		cmd := `open "` + downloadDir + `"`
  15. 		exec.Command("/bin/bash", "-c", cmd).Start()
  16. 	} else {
  17. 		downloadDir = strings.ReplaceAll(downloadDir, "/", "\\")
  18. 		exec.Command("explorer", downloadDir).Start()
  19. 	}
  20. }

Edit

More simplified version, use downloadDir := filepath.Join(homeDir, "Downloads") instead of downloadDir = strings.ReplaceAll(downloadDir, "/", "\\")

  1. package main
  3. import (
  4. 	"os"
  5. 	"os/exec"
  6. 	"path/filepath"
  7. 	"runtime"
  8. )
  10. func main() {
  11. 	homeDir, _ := os.UserHomeDir()
  12. 	downloadDir := filepath.Join(homeDir, "Downloads")
  13. 	if runtime.GOOS == "darwin" {
  14. 		exec.Command("open", downloadDir).Start()
  15. 	} else {
  16. 		exec.Command("explorer", downloadDir).Start()
  17. 	}
  18. }

  15. 		cmd = "explorer"

According to @panapol-p point out here

  1. package main
  3. import (
  4. 	"os"
  5. 	"os/exec"
  6. 	"path/filepath"
  7. 	"runtime"
  8. )
  10. func main() {
  11. 	homeDir, _ := os.UserHomeDir()
  13. 	cmd := "open"
  14. 	downloadDir := filepath.Join(homeDir, "Downloads")
  15. 	if runtime.GOOS == "windows" {
  16. 		cmd = "explorer"
  17. 		downloadDir = "shell:downloads"
  18. 	}
  19. 	exec.Command(cmd, downloadDir).Start()
  20. }

我建议您使用特定的文件夹，而不是自己拼接路径，因为当您将应用程序安装在自定义下载路径上时，您的应用程序将以错误的条件运行。

特定文件夹是在系统中注册的标准文件夹，适用于XP或更高版本的Windows。

对于手动操作，您可以按照以下步骤进行：

win + r -> shell:{specific folder}

例如：

win + r -> shell:downloads

对于Golang，您可以使用以下代码：

  1. err := exec.Command("explorer", "shell:downloads").Start()
  2. if err != nil {
  3.     log.Fatalln(err.Error())
  4. }

[for window]<br>
I recommend using a specific folder instead of joining the path by yourself,
because when you install the application on a custom download path, your application will be run with the wrong condition.

a specific folder is a standard folder that was registered with the system and this one is on XP or higher version of window

for manual, you can use like this
> win + r -> shell:{specific folder}

example
> win + r -> shell:downloads

for golang you can use like this

  1. err := exec.Command(&quot;explorer&quot;, &quot;shell:downloads&quot;).Start()
  2. if err != nil {
  3. 	log.Fatalln(err.Error())
  4. }
