How to deal with quoted and unquotes strings when executing it in command prompt?
问题
// 输入来自一个 JSON 请求，格式如下{"inputString" : "\"C:\\Program Files (x86)\-Zip\z.exe\" x c:\\temp\\test.zip -oc:\\temp\\test"}package mainimport ("fmt""os/exec")func main() {// 接收到的输入将是这种格式var inputstring string = "\"C:\\Program Files (x86)\-Zip\z.exe\" x c:\\temp\\firmware8.zip -oc:\\temp\\fw"cmd := exec.Command("cmd", "/c", inputstring)out, err := cmd.Output()fmt.Println("doneee", string(out), "err", err)}
输出："C:\Program Files (x86)\7-Zip\7z.exe" 不被识别为内部或外部命令，可执行程序或批处理文件。
"C:\Program Files (x86)\7-Zip\7z.exe" x c:\temp\test.zip -oc:\temp\test - 我需要在命令提示符下运行这个命令，但它只执行了被标记的部分。
由于输入字符串不是静态的（它来自 JSON），所以我们不能将其拆分为参数。
英文:
input comes from an JSON request which looks like{"inputString" : "\"C:\\Program Files (x86)\\7-Zip\\7z.exe\" x c:\\temp\\test.zip -oc:\\temp\\test"}package mainimport ("fmt""os/exec")func main() {//Input received will be of this formatvar inputstring string = "\"C:\Program Files (x86)\7-Zip\7z.exe\" x c:\temp\firmware8.zip -oc:\temp\fw"cmd := exec.Command("cmd", "/c", inputstring)out, err := cmd.Output()fmt.Println("doneee", string(out), "err", err)}
Output : "'\"C:\Program Files (x86)\7-Zip\7z.exe\\
"' is not recognized as an internal or external command,\r\noperable program or batch file.\r\n"
"C:\Program Files (x86)\7-Zip\7z.exe" x c:\temp\test.zip -oc:\temp\test - I have to run this command on command prompt but it is just executing the part which is highlighted
As the input string is not static (it comes from a JSON),So we cannot split them into arguments

你可以使用原始字符串。查看这个教程。
var inputstring string = `"C:\Program Files (x86)-Zipz.exe" x c:\temp\test.zip -oc:\temp\test`
英文:
You can use raw string. look this tutorial.
var inputstring string = `"C:\Program Files (x86)-Zipz.exe" x c:\temp\test.zip -oc:\temp\test`

得分: -2
var inputstring string = ""C:\Program Files (x86)\7-Zip\7z.exe" x c:\temp\firmware8.zip -oc:\temp\fw"
var buf, stderr bytes.Buffer
proc := exec.Command("cmd")
proc.SysProcAttr = &syscall.SysProcAttr{CmdLine: fmt.Sprintf(/c "%s", inputstring)} //添加这行代码有助于将cmd添加为单行
proc.Stderr = &stderr
proc.Stdout = &buf
proc.Start()
time.Sleep(5 * time.Second)
fmt.Println("完成", buf.String(), "错误信息为", stderr.String())
英文:
var inputstring string = "\"C:\\Program Files (x86)\-Zip\z.exe\" x c:\\temp\\firmware8.zip -oc:\\temp\\fw"var buf, stderr bytes.Buffer*proc := exec.Command("cmd")proc.SysProcAttr = &syscall.SysProcAttr{CmdLine: fmt.Sprintf(`/c "%s"`, inputstring)}* //Adding this line helped to add the cmd as single lineproc.Stderr = &stderrproc.Stdout = &bufproc.Start()time.Sleep(5 * time.Second)fmt.Println("doneee", buf.String(), "error is ", stderr.String())
