Html 是否可以使用powershell单击angularjs按钮？

然后，当我写入控制台以查看$BTN是什么时，我得到一个错误：

$Link = 'https://url.com/folder/2880'
$html = Invoke-WebRequest -Uri $Link -UseDefaultCredentials
$btnclick = $html.getElementsByTagName("div") | Where-object{$_.Name -like 'ng-click="vm.callbacks.compareAll();"' }

最后，我想我会像

$btnclick.Click（）

，然后在

href

上执行另一个

getElement

，这样我就可以拉

分出来

任何帮助完成这项工作的人都将不胜感激。高级概述是，我需要从网页中单击AngularJS按钮，然后从生成的a href标记中提取一段URL以在wget中使用。

在AngularJS网页中调用WebRequest

是无用的，因为存在客户端javascript呈现。您可以将powershell+selenium+量角器组合使用（需要powershell v5）：

如果你不想依赖Chrome浏览器，你可以使用无头幻影。它将以同样的方式工作，您只需下载不同的软件包：

# initialize selenium
$protractorPackage = Install-Package Protractor -Destination ".\NugetPackages" -Force -Source 'https://www.nuget.org/api/v2' -ProviderName NuGet
Add-Type -Path ".\Selenium.WebDriver.$($protractorPackage.Where({$_.name -eq "Selenium.WebDriver"}).version)\lib\net40\WebDriver.dll"
Add-Type -Path ".\Protractor.$($protractorPackage.Where({$_.name -eq "Protractor"}).version)\lib\net40\Protractor.dll"

# initialize chrome driver
$chromeDriverPackage = Install-Package Selenium.WebDriver.ChromeDriver -Destination "." -Force -Source 'https://www.nuget.org/api/v2' -ProviderName NuGet
$Env:Path += ";" + ((Resolve-Path ".\Selenium.WebDriver.ChromeDriver.$($chromeDriverPackage.Version)\driver\win32") -join ";")
$Selenium = New-Object OpenQA.Selenium.Chrome.ChromeDriver

# interact with website
$Selenium.Manage().Timeouts().SetScriptTimeout([TimeSpan]::FromSeconds(15)) # Configure timeouts (important since Protractor uses asynchronous client side scripts)
$Protractor = New-Object Protractor.NgWebDriver($Selenium)
try
{
    $Protractor.Url = "https://url.com/folder/2880"
    $Protractor.WaitForAngular() # sync with angular, this waits for all elements to load

    $Protractor.FindElement([OpenQA.Selenium.By]::CssSelector('[ng-click="vm.callbacks.compareAll();"]')).Click();

    Write-Host "Url is: $($Protractor.Url)"
    $FullhtmlDOM = $Protractor.PageSource
    Write-Host "Full page source: $FullhtmlDOM"
}
finally
{
    $Protractor.Dispose()
}

如果你对IE很满意，那么创建IE COM对象就会得到你想要的

...
# initialize phantomjs driver
$phantomJsDriverPackage = Install-Package Selenium.WebDriver.PhantomJS -Destination "." -Force -Source 'https://www.nuget.org/api/v2' -ProviderName NuGet
$Env:Path += ";" + ((Resolve-Path ".\Selenium.WebDriver.PhantomJS.$($phantomJsDriverPackage.Version)\driver") -join ";")
$Selenium = New-Object OpenQA.Selenium.PhantomJS.PhantomJSDriver
...

如果要使其可见，请执行以下操作：

$ie = New-Object -ComObject "InternetExplorer.Application"
$ie.Navigate("URL GOES HERE")
$Document = $ie.document
$Document.GetElementsByTagName('div')

这是COM对象上的Microsoft页面

还有一个是在powershell中使用它

---

值得一提的是，默认情况下未定义NuGet源代码，因此如果

安装包

抛出错误，请尝试添加参数

-source'https://www.nuget.org/api/v2'-ProviderName NuGet

感谢您的示例，我只是修改了安装部分，因为Digrator nuget install也带来了Selenium.WebDriver.

调用WebRequest

的Microsoft.PowerShell.Commands.HtmlWebResponseObject使用IE无头渲染DOM，除非添加

-UseBasicParsing

。您尝试过

$html.ParsedHtml.getElementsByTagName（'div'）吗|名称在哪里-如“…”

Invoke WebRequest

的Microsoft.PowerShell.Commands.HtmlWebResponseObject使用IE无头呈现DOM，除非您添加

-UseBasicPassing

，并且返回的对象似乎具有

click（）

方法。
