Powershell向下滚动网页/ Powershell屏幕截图 [英] Powershell Scroll down a webpage / Powershell Screenshot

问题描述

如何在powershell中打开网页并向下滚动。

实际上，我制作一个脚本，它会自己做一个网络报告，我想要。我可以打开网页，并用我的脚本开始测试，但我想让我的脚本向下滚动，以便可以采取正确的屏幕截图。请帮助。

准确地说，我希望我的脚本打开一个名为testmy.net的网站，并做一个网络报告。我想要的只是报告的截图，裁剪一切。我非常感谢任何帮助。

Q）如何在PS中向下滚动网页？我打开网站，我想向下滚动？

Q）如何截取特定内容的屏幕截图？
（经过一些研究，我得到了一些可以截取整个桌面的屏幕截图）

我附上了我需要的确切的屏幕截图。 p>

脚本从这里开始：

  $ ie = new-object -comobject InternetExplorer.Application -property`
 @ {navigate2 =http://testmy.net/SmarTest/combinedAuto; visible = $ true} 
 
＃等待页面完成加载
 
 $ ie.fullscreen = $ true 
 
 do {sleep 5} until （$ not.Busy））
 
＃获取ScreenShot（从Stackflow获取的脚本）
 [Reflection.Assembly] :: LoadWithPartialName（System.Drawing）
函数截图（[Drawing.Rectangle] $ bounds，$ path）{
 $ bmp = New-Object Drawing.Bitmap $ bounds.width，$ bounds.height 
 $ graphics = [Drawing.Graphics] :: FromImage（$ bmp）
 
 $ graphics.CopyFromScreen（$ bounds.Location，[Drawing.Point] :: Empty，$ bounds.size）
 
 $ bmp。保存（$ path）
 
 $ graphics.Dispose（）
 $ bmp.Dispose（）
} 
 
 $ bounds = [Drawing.Rectangle] :: FromLTRB（0，0，1000，900）
截图$ boundsC：\screenshot.png
  

解决方案

我想你正在寻找真的速度和肮脏。如果这是真的，并且您不介意丑陋，请尝试使用SendKeys 。 p>

  $ ie = new-object -comobject InternetExplorer.Application -property`
 @ {navigate2 =http：// testmy .net / SmarTest / combinedAuto; visible = $ true} 
 
＃等待页面完成加载
 
 $ ie.fullscreen = $ true 
 
 do {sleep 5} until （-not（$ ie.Busy））
 
 [System.Windows.Forms.Cursor] :: Position = New-Object system.drawing.point（700,700）
 [System.Windows 
 
 [Reflection.Assembly] :: LoadWithPartialName（System.Drawing）。 ）
函数截图（[Drawing.Rectangle] $ bounds，$ path）{
 $ bmp = New-Object Drawing.Bitmap $ bounds.width，$ bounds.height 
 $ graphics = Drawing.Graphics] :: FromImage（$ bmp）
 
 $ graphics.CopyFromScreen（$ bounds.Location，[Drawing.Point] :: Empty，$ bounds.size）
 
 $ bmp.Save（$ path）
 
 $ graphics.Dispose（）
 $ bmp.Dispose（）
} 
 
 $ bounds = Drawing.Rectangle] :: FromLTRB（0，0，1000，900）
截图$ boundsC：\tmp\screenshot.png
  

继续用你发送的向下箭头的数量来解决问题，因此编辑 {DOWN 10} 。

害怕你会有足够的时间问题，你最终会回去使用另一个工具，但是。

请注意，我在测试期间更改了espn.com的网址。不知道发生了什么 - 你的速度测试？似乎要加载大约三个不同的网页。

How to open a webpage in powershell and scroll down.

Actually I am making a script which will do a network report on its own and give me a screenshot which I want. I can open the webpage and start the test with my script, but I want my script to scroll down so that the correct screenshot could be taken. Please Help.

To be precise, I want my script to open a website called testmy.net and do a network report. I want to take the screenshot of just the report and crop everything else. I would really appreciate any help.

Q) How do I scroll down a webpage in PS? I open the website and I want to scroll down?

Q) How do I take a screenshot of only a particular thing? (After some research I got some part which could take a screenshot of the whole desktop)

I have attached the screenshot of exact thing I need.

Script Starts Here:

$ie = new-object -comobject InternetExplorer.Application -property `
    @{navigate2="http://testmy.net/SmarTest/combinedAuto"; visible = $true}

# Wait for the page to finish loading

$ie.fullscreen = $true

do {sleep 5} until (-not ($ie.Busy))

# Take A ScreenShot (Script taken from Stackflow)
[Reflection.Assembly]::LoadWithPartialName("System.Drawing")
function screenshot([Drawing.Rectangle]$bounds, $path) {
$bmp = New-Object Drawing.Bitmap $bounds.width, $bounds.height
$graphics = [Drawing.Graphics]::FromImage($bmp)

$graphics.CopyFromScreen($bounds.Location, [Drawing.Point]::Empty, $bounds.size)

$bmp.Save($path)

$graphics.Dispose()
$bmp.Dispose()
}

$bounds = [Drawing.Rectangle]::FromLTRB(0, 0, 1000, 900)
screenshot $bounds "C:\screenshot.png"

解决方案

I think you're looking for really quick and dirty. If that's true, and you don't mind ugly, try using SendKeys.

$ie = new-object -comobject InternetExplorer.Application -property `
    @{navigate2="http://testmy.net/SmarTest/combinedAuto"; visible = $true}

# Wait for the page to finish loading

$ie.fullscreen = $true

do {sleep 5} until (-not ($ie.Busy))

[System.Windows.Forms.Cursor]::Position = New-Object system.drawing.point(700,700)
[System.Windows.Forms.SendKeys]::SendWait({DOWN 10})

# Take A ScreenShot (Script taken from Stackflow)
[Reflection.Assembly]::LoadWithPartialName("System.Drawing")
function screenshot([Drawing.Rectangle]$bounds, $path) {
    $bmp = New-Object Drawing.Bitmap $bounds.width, $bounds.height
    $graphics = [Drawing.Graphics]::FromImage($bmp)

    $graphics.CopyFromScreen($bounds.Location, [Drawing.Point]::Empty, $bounds.size)

    $bmp.Save($path)

    $graphics.Dispose()
    $bmp.Dispose()
}

$bounds = [Drawing.Rectangle]::FromLTRB(0, 0, 1000, 900)
screenshot $bounds "C:\tmp\screenshot.png"

Keep messing around with the number of down arrows you send until it's right -- so edit {DOWN 10}.

Scared you're going to have enough timing issues that you eventually go back and use another tool, however. How many of these do you have to take?

Note that I did change the URL to espn.com while testing. Not sure what's going on at yours -- a speed test? Seemed to load about three different pages.
