抓取(爬取)网上信息的脚本程序,俗称网络蜘蛛。
powershell中自带了这样的两个命令,【Invoke-WebRequest】和【Invoke-RestMethod】,但这两个命令有时候会乱码。
现在转帖分享, 某个【歪果仁】写的脚本。来源于 墙外出处: https://gist.github.com/angel-vladov/9482676
function Read-HtmlPage {
param ([Parameter(Mandatory=$true, Position=0, ValueFromPipeline=$true)][String] $Uri) # Invoke-WebRequest and Invoke-RestMethod can't work properly with UTF-8 Response so we need to do things this way.
[Net.HttpWebRequest]$WebRequest = [Net.WebRequest]::Create($Uri)
[Net.HttpWebResponse]$WebResponse = $WebRequest.GetResponse()
$Reader = New-Object IO.StreamReader($WebResponse.GetResponseStream())
$Response = $Reader.ReadToEnd()
$Reader.Close() # Create the document class
[mshtml.HTMLDocumentClass] $Doc = New-Object -com "HTMLFILE"
$Doc.IHTMLDocument2_write($Response) # Returns a HTMLDocumentClass instance just like Invoke-WebRequest ParsedHtml
