Question

我想执行/链接几个PowerShell cmdlet。来自CSV的初始输入。 CSV中的值可能会比初始命令所需的要多，但在链的下游可能需要它们。像这样：

 CSV
 email, fname, lname, clubNo, permission
 A@email.com, John, Smith, 12, R
 B@email.com, Jean, Smith, 12, R
 C@email.com, Jack, Smith, 12, R

然后连锁

 import-csv file.txt | new-user -env Dev | set-role | export-csv result.txt

新用户只需要电子邮件，env 设定角色需要电子邮件，clubNo，env和烫发

我认为我的新用户cmdlet应该看起来像这样，但是不起作用：

function global:new-user {
param(  
    [Parameter(ValueFromPipelineByPropertyName = $true, mandatory = $true)][validateset('DEV', 'QA', 'PT', 'PLT', 'SIT', 'APIS', 'PD', 'Sandbox')][STRING]$env,
    [Parameter( mandatory = $True, ValueFromPipelineByPropertyName = $true)][ValidateScript({ValidateEmail($_)})][String]$Email,
    [String]$userKey="xyz",
    [String]$secret="abc"
) 

Begin {
    $dc = "domain.com"
    $auth = "env=$env&userkey=$userKey&secret=$secret"
    $record = New-Object psobject
    $record | add-member env $env
}

process {
    $result = Invoke-RestMethod "https://accounts.$dc/accounts.search?$auth" -Method Post -Body @{"query" = "select UID FROM accounts where profile.email contains '$Email'"}
    If (-not $result.errorCode ) {
        $record | Add-Member uid $result.uid
    }
    $record | Add-Member ErrorCode $result.errorCode -Force
}

end {
    Write-Output $rescord
}

}

但是我在出站管道上只看到一条记录

开始/结束块在cmdlet执行期间被调用一次，因此您只需在开始处创建一个$ record对象，覆盖其在流程块中的属性，然后在管道末尾将其发送一次。您也不会保留csv文件中的其他属性。我猜您只需要在流程块中做所有事情，而不是创建新对象，而只需继续使用输入对象（$ _）

begin {
   $dc = "domain.com"
   $auth = "env=$env&userkey=$userKey&secret=$secret"
}
process {

    $_ | add-member env $env
    $result = Invoke-RestMethod "https://accounts.$dc/accounts.search?$auth" -Method Post -Body @{"query" = "select UID FROM accounts where profile.email contains '$Email'"}
    If (-not $result.errorCode ) {
        $_ | Add-Member uid $result.uid
    }
    $_ | Add-Member ErrorCode $result.errorCode -Force
    Write-Output $_
}
end {}

将管道输入直接写入管道输出
