使用 Windows Powershell 打开浏览器

Question

我正在学习 Powershell。我在网上找到了几个脚本，修改它们以使文件在 Chrome 和 IE 中打开。该脚本可以正常工作，但 IE 打开时会显示空白页面，但不会像在 Chrome 中那样在其他选项卡中打开所有其他 link。此外，我收到以下错误消息。我希望看到的行为是在 Chrome 和 IE 中打开每个 link，然后在一定时间后关闭每个浏览器。

收到错误：

You cannot call a method on a null-valued expression.
At line:92 char:13
+             $ie.navigate($site );
+             ~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : ObjectNotFound: (ie:String) [Remove-Variable], ItemNotFoundException

代码如下，下面列出了文本文件中的 link。

# How long to wait between open site commands
$waitBetweenSitesS = 7;

# How long to wait after a browser's last site before closing its window
$waitBeforeBrowserClose = 7;

# How long to wait between browsers
$waitBetweenBrowsers = 7;

# Name of the file containing the sites to open
$siteUrlFile = "C:\Scripts\URLs.txt";


# Browsers to start
$browsers = @("chrome", "iexplore")

# Start of the script

Function Open-IETabs {
param (
[string[]]$sites )
begin {
$Ie = New-Object -ComObject InternetExplorer.Application }
process {

foreach ($Link in $sites)
{
$Ie.Navigate2($Link, 0x1000)
}
}
end
{
$Ie.Visible = $true }
}
#$path = read-host 'Enter the path of ppm list file'
$sites = gc "C:\Scripts\URLs.txt"
Open-IETabs -Url $sites

# Browsers
   foreach ($browser in $browsers)
   {

# Sites
      $siteCount = 0;
      foreach ($site in $sites)
      {
         $siteCount++;

         if ($siteCount -eq 1)
         {
            if ($browser -eq "chrome" -or $browser -eq "iexplore")
            {
               # Start the browser with an empty tab because the first page load is currently not captured by uberAgent
               $process = Start-Process -PassThru $browser "about:blank"
            }
            else
            {
               # Start the browser with the first site
               $process = Start-Process -PassThru $browser $site
            }

            # Store the browser's main process (the first one started)
            $browserProcess = $process;

            # Wait for the window to open
            while ($process.MainWindowHandle -eq 0)
            {
               Start-Sleep 1
            }

            if ($browser -eq "chrome" -or $browser -eq "firefox")
            {
               # Open the first site in a new tab
               Start-Process $browser $site
            }
         }
         elseif ($browser -eq "iexplore")
         {
            # Additional IE tabs need to be opened differently, or new windows will be created instead

            $navOpenInNewTab = 0x800;

            # Get running Internet Explorer instances
            $app = New-Object -ComObject shell.application;

            # Grab the last opened tab
            $ie = $app.Windows() | Select-Object -Last 1;

            # Open the site in a new tab
            $ie.navigate($site, $navOpenInNewTab);

            # Release the COM objects
            Remove-Variable ie;
            Remove-Variable app;
         }
         else
         {
            # Addition tabs in Chrome/Firefox
            Start-Process $site #$browser 
         }

         Start-Sleep $waitBetweenSitesS;
      }

      Start-Sleep $waitBeforeBrowserClose;

      # Close the browser
      $browserProcess.CloseMainWindow();
      $browserProcess = $null;

      Start-Sleep $waitBetweenBrowsers;

      }

我无法重现您的错误。不管怎样，你的代码对于你想做的事情来说似乎过于复杂了。我没有得到 Open-IETabs 函数（因为它似乎应该做你在浏览器迭代中的代码所做的事情。也许这可能是一个开始：

# How long to wait between open site commands
$waitBetweenSitesS = 7;

# How long to wait after a browser's last site before closing its window
$waitBeforeBrowserClose = 7;

# How long to wait between browsers
$waitBetweenBrowsers = 7;

$sites = 
"https://www.google.com/maps/",
"https://www.nytimes.com/",
"https://www.nbcnews.com/"

# Start of the script

#IEXPLORE
$Ie = New-Object -ComObject InternetExplorer.Application
$ie.visible = $true
foreach ($site in $sites){
    $Ie.Navigate2($site, 0x1000)
    start-sleep -seconds $waitBetweenSitesS
}

Start-Sleep -seconds $waitBetweenBrowsers

#CHROME
$process = Start-Process -PassThru "chrome" "about:blank"
foreach ($site in $sites){
    Start-Process "chrome" $site
    start-sleep -seconds $waitBetweenSitesS
}
