PowerShell的 - 如何正确地传递字符串参数？ [英] PowerShell - How do I pass string parameters correctly?

问题描述

是否有文档或字符串传递到PowerShell函数的规则的文章？我只是试图做一些字符串连接/格式，但它把所有的参数代入第一个占位符。

code

 函数CreateAppPoolScript（[字符串] $ AppPoolName，[字符串] $ AppPoolUser，[字符串] $ AppPoolPass）
{
    ＃命令创建一个IIS应用程序池
    $ AppPoolScript =CSCRIPT ADSUTIL.VBS CREATESVC / AppPools / $ AppPoolNameIIsApplicationPool`n
    $ AppPoolScript + =的cscript adsutil.vbs设置，SVC / AppPools / $ AppPoolName / wamusername将$ AppPoolUser'N
    $ AppPoolScript + =的cscript adsutil.vbs设置，SVC / AppPools / $ AppPoolName /的WAMUserPass$ AppPoolPass'N
    $ AppPoolScript + =的cscript adsutil.vbs设置，SVC / AppPools / $ AppPoolName / AppPoolIdentityType，3    返回$ AppPoolScript
}
$ S = CreateAppPoolScript（名，用户，通）
写主机$ S
 

输出

  CSCRIPT ADSUTIL.VBS创建SVC / AppPools /名用户通行证IIsApplicationPool
CSCRIPT adsutil.vbs设置SVC / AppPools /用户名合格/ wamusername将
CSCRIPT adsutil.vbs设置SVC / AppPools /用户名合格/的WAMUserPass
CSCRIPT adsutil.vbs设置SVC / AppPools /用户名合格/ AppPoolIdentityType3
 

解决方案

失去了括号和逗号。

调用你的函数为：

  $ S = CreateAppPoolScript名，用户，通行证
 

给出了：

  CSCRIPT ADSUTIL.VBS创建SVC / AppPools /名IIsApplicationPool
CSCRIPT adsutil.vbs设置SVC / AppPools /名/ wamusername将，用户
CSCRIPT adsutil.vbs设置SVC / AppPools /名/的WAMUserPass，通行证
CSCRIPT adsutil.vbs设置SVC / AppPools /名/ AppPoolIdentityType3
 

Is there documentation or an article on the rules for passing strings into PowerShell functions? I just trying to do some string concatenation/formatting, but it's putting all the parameters into the first placeholder.

Code

function CreateAppPoolScript([string]$AppPoolName, [string]$AppPoolUser, [string]$AppPoolPass)
{
    # Command to create an IIS application pool
    $AppPoolScript = "cscript adsutil.vbs CREATE ""w3svc/AppPools/$AppPoolName"" IIsApplicationPool`n"
    $AppPoolScript += "cscript adsutil.vbs SET ""w3svc/AppPools/$AppPoolName/WamUserName"" ""$AppPoolUser""`n"
    $AppPoolScript += "cscript adsutil.vbs SET ""w3svc/AppPools/$AppPoolName/WamUserPass"" ""$AppPoolPass""`n"
    $AppPoolScript += "cscript adsutil.vbs SET ""w3svc/AppPools/$AppPoolName/AppPoolIdentityType"" 3"

    return $AppPoolScript
}
$s = CreateAppPoolScript("name", "user", "pass")
write-host $s

Output

cscript adsutil.vbs CREATE "w3svc/AppPools/name user pass" IIsApplicationPool
cscript adsutil.vbs SET "w3svc/AppPools/name user pass/WamUserName" ""
cscript adsutil.vbs SET "w3svc/AppPools/name user pass/WamUserPass" ""
cscript adsutil.vbs SET "w3svc/AppPools/name user pass/AppPoolIdentityType" 3

解决方案

Lose the parentheses and commas.

Calling your function as:

$s = CreateAppPoolScript "name" "user" "pass"

gives:

cscript adsutil.vbs CREATE "w3svc/AppPools/name" IIsApplicationPool
cscript adsutil.vbs SET "w3svc/AppPools/name/WamUserName" "user"
cscript adsutil.vbs SET "w3svc/AppPools/name/WamUserPass" "pass"
cscript adsutil.vbs SET "w3svc/AppPools/name/AppPoolIdentityType" 3
