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。

核心代码
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 传教士 转帖并修改的文章 2016-01-01, 允许再次转载，但必须保留名字和出处，否则追究法律责任 }原文函数

The built in Invoke-WebRequest and Invoke-RestMethod fail miserably.
