如何让PowerShell脚本请求网络凭据时自动预设域名？

需求概述 #

现有PowerShell脚本可实现PS模块自动安装、最新文件获取功能，需优化以下两点：

• 自动预设域名，用户无需在用户名字段手动输入域名前缀
• 请求网络凭据而非本地凭据，适配共享资源访问和远程脚本执行场景

Add-Type -Name Window -Namespace Console -MemberDefinition '
[DllImport("Kernel32.dll")]
public static extern IntPtr GetConsoleWindow();

[DllImport("user32.dll")]
public static extern bool ShowWindow(IntPtr hWnd, Int32 nCmdShow);'

[VOID] [Console.Window]::ShowWindow([Console.Window]::GetConsoleWindow(), 0)

    # 替换为实际域名
    $domain = "YOUR_DOMAIN"
    # 弹出凭据窗口，自动填充域名前缀
    $credential = Get-Credential -UserName "$domain\" -Message "请输入网络凭据"

    # 使用网络凭据启动主脚本
    Start-Process -FilePath powershell.exe -ArgumentList "C:\Local Folder\Main script.ps1" -Credential $credential
}

[void]$Form.ShowDialog()

关键修改说明 #

• 预设域名的凭据请求：在otbx函数中，通过Get-Credential -UserName "$domain\"自动在用户名输入框填充域名\前缀，用户仅需输入自身用户名即可
• 网络凭据适配：Get-Credential弹出的标准凭据窗口默认支持网络身份验证，满足共享资源访问和远程脚本执行的权限需求
• 控件逻辑修复：将进度条创建移到函数外，避免控件添加时的未定义错误；移除原脚本中未定义的$Button1引用；修正结束按钮的初始可见性设置
• 模块安装优化：在Install-Module中添加-Force -AllowClobber -Scope CurrentUser参数，避免安装过程中的交互提示和权限问题
• 凭据传递优化：将完整凭据对象传入Start-Process，替代原脚本中不完整的Domain\写法，确保身份验证正常执行
