抓?。ㄅ廊。┚W(wǎng)上信息的腳本程序，俗稱網(wǎng)絡(luò)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(xiàn)在轉(zhuǎn)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

原文函數(shù)
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.
