抓?。ㄅ廊。┚W上信息的腳本程序，俗稱網絡蜘蛛。
powershell中自帶了這樣的兩個命令，【Invoke-WebRequest】和【Invoke-RestMethod】，但這兩個命令有時候會亂碼。

現在轉帖分享， 某個【歪果仁】寫的腳本。來源于 墻外出處： https://gist.github.com/angel-vladov/9482676

核心代碼

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($Response)# Returns a HTMLDocumentClass instance just like Invoke-WebRequest ParsedHtml$Doc#powershell 傳教士 轉帖并修改的文章 2016-01-01, 允許再次轉載，但必須保留名字和出處，否則追究法律責任}

原文函數

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  $Doc}

PowerShell function you can use for reading UTF8 encoded HTML pages content. The built in Invoke-WebRequest and Invoke-RestMethod fail miserably.
