从 Powershell 中的文本文件中提取值

Question

我有一个脚本应该连接到服务器并更新用户的值。现在，我可以让该脚本为单个用户执行此操作，但我正在尝试获取它，以便它可以从文本文件中为多个用户执行此操作。该脚本具有三个功能，第一个创建与服务器的连接，第二个搜索用户，并从服务器的数据库中提取用户 GUID，第三个设置用户的值。

我尝试更新 getuser 函数，以便它使用 get-content 从文本文件中提取用户数据，然后使用 foreach-object，但是当我运行脚本时，它会继续询问电子邮件地址，然后出错。

这里是来自 getuser 的 sn-ps 和主要功能。如果有人有任何建议，我将不胜感激。

function getUser($email)
{

   $methodName = "getUser()";
   enterMethod($methodName);
   $response = $null;

   <# Create and set the headers for the REST request #>
   $headers = @{}
   $headers.add("Authorization", $global:authString);
   $headers.add("Content-Type", "application/vnd.blackberry.users-v1+json");



   $request = $global:uemBaseUrl + "/users?query=emailAddress=" + $email;


   # Invoke RESTMethod to call users API to obtain users in the system
   try
   {
       $response = Invoke-RestMethod -Method GET -Headers $headers -Uri $request;
       if (($response.users -ne $null) -and ($response.users.length -eq 1))
       {
           Write-Host([string]::Format("User with email address '{0}' was found", $email));

这是完整的工作脚本。此脚本允许您一次执行一个用户。

你的问题很可能在这里：

 $getUserResponse = get-content .\users.txt $emailaddress;
 $getUserResponse = ForEach-Object

如果不运行它会很难调试，但是你想用这个做什么？：

$getUserResponse = get-content .\users.txt $emailaddress

$emailAddress 从我可以看到是一个从未定义过的。 users.txt 是否只是一个充满用户文件的逐行文件？

ForEach-Object 还需要通过管道传输数据。
