如何正确转义命令行参数

Question

我正在开发一个简单的应用程序，该应用程序应该加密命令行给出的字符串，然后将其写入注册表。不幸的是，如果密码包含特殊字符，例如 " & < > | .所以例如：

Encrypt.exe /Password:Password /reg       --> works fine
Encrypt.exe /Password:Password"&<>| /reg  --> the password variable contains: Password&<>| /reg which is wrong
Encrypt.exe /Password:Password&<>|        --> this outputs: "> was unexpected at this time." but no idea where this text is coming from
Encrypt.exe /Password:"Password&<>|"      --> this works, but note that the password can't contains a " char and the encrypted/decrypted string will contain a " at the beginning and at the end

所以我的问题是，如何将字符串Password&<>|正确传递给我的应用程序？

Answer 1

转义.bat文件中的某些字符：

&   use  ^&
<   use  ^<
>   use  ^>
|   use  ^|
"   use  ""
