是否可以在Windows Scripting Host(WSH)VBS脚本中读取系统环境变量?

(我正在使用Windows Scripting Host编写VBScript以获取Cruise Control的任务,并希望获取项目构建URL。)

以下是一个示例(取自here):

Set oShell = CreateObject( "WScript.Shell" )
user=oShell.ExpandEnvironmentStrings("%UserName%")
comp=oShell.ExpandEnvironmentStrings("%ComputerName%")
WScript.Echo user & " " & comp

来自here ...

Set WshShell = WScript.CreateObject("WScript.Shell")

Set WshProccessEnv = WshShell.Environment("Process")
Set WshSysEnv = WshShell.Environment("System")

Wscript.Echo WshSysEnv("NUMBER_OF_PROCESSORS")
Wscript.Echo WshProccessEnv("Path")

现有答案都很有帮助,但让我尝试务实的摘要

通常,您希望 当前流程定义环境变量

CreateObject("WScript.Shell").ExpandEnvironmentStrings("%TEMP%")

这相当于(注意变量名称周围没有%):

CreateObject("WScript.Shell").Environment("Process").Item("TEMP")

警告:不要忽略("Process)部分:如果这样做,您将获得系统范围' s变量的定义;见下文。

.ExpandEnvironmentStrings在概念上更简单,更灵活:它可以使用 embedded %扩展任意字符串 - 附带的)环境变量参考; e.g:

CreateObject("WScript.Shell").ExpandEnvironmentStrings("My name is %USERNAME%")

在极少数情况下,您可能必须特定范围访问环境变量定义 (当前流程除外)。

  sScope = "System" ' May be: "Process", "User", "Volatile", "System"
  CreateObject("WScript.Shell").Environment(sScope).Item("TEMP")

注意:如上所述,省略scope参数默认为System范围。

警告:以这种方式访问​​值不会展开:环境变量值可以嵌套:它们可以引用其他环境变量 在上面的示例中,返回值为%SystemRoot%\TEMP,其中包含未展开%SystemRoot%的引用。
要展开结果,请将其传递给.ExpandEnvironmentStrings(),如上所示。

Set WshShell = CreateObject("WScript.Shell")    
Set WshEnv = WshShell.Environment
WScript.Echo "WINDIR=" & WshEnv.Item("WINDIR")  & vbCrLf & vbCrLf   
Set WshShell = CreateObject("WScript.Shell")
WScript.Echo "Environment System:"              & vbCrLf & _ 
         "..............................................."

For Each IEnv In WshShell.Environment("System")
    WScript.Echo IEnv
Next

WScript.Echo vbCrLf & "Environment User:"       & vbCrLf & _   
        "..............................................."

For Each IEnv In WshShell.Environment("User") 
    WScript.Echo IEnv
Next

WScript.Echo vbCrLf & "Environment Volatile:"   & vbCrLf & _ 
       "..............................................."

For Each IEnv In WshShell.Environment("Volatile")
    WScript.Echo IEnv
Next

WScript.Echo vbCrLf & "Environment Process:"    & vbCrLf & _ 
       "..............................................."

For Each IEnv In WshShell.Environment("Process")
    WScript.Echo IEnv
Next

这对我有用:

Dim objNetwork
Set objNetwork = CreateObject("WScript.Network")
MsgBox objNetwork.UserName

或来自shell:

Set wshShell = WScript.CreateObject( "WScript.Shell" )
strUserName = wshShell.ExpandEnvironmentStrings( "%USERNAME%" )

或来自环境变量(它应该可以工作,但是当我测试它是错误的!):

Set WshShell = CreateObject("WScript.Shell")
Set WshEnv = WshShell.Environment
MsgBox "USERNAME=" & WshEnv.Item("USERNAME")
