　　vb抓取网页内容(EndSub显示GoogleChrome显示的相同代码。怎么了？)

　　我正在尝试创建一个 Windows 桌面应用程序，该应用程序将转到指定站点并从该站点获取 HTML。我发现了很多这样做的例子，但由于某种原因，它不适用于传统的 Google 协作平台页面。该程序需要在 Google 协作平台页面的正文中找到简单的文本。当您“查看页面源代码”时，它不会显示与 Google Chrome 显示相同的代码。怎么了？

<p>Public Sub Scrape(strURL)

Try

Dim wrResponse As WebResponse

Dim wrRequest As WebRequest = HttpWebRequest.Create(strURL)

textScrape = "Extracting..." & Environment.NewLine

wrResponse = wrRequest.GetResponse()

Using sr As New StreamReader(wrResponse.GetResponseStream())

strOutput = sr.ReadToEnd()

&#39; Close and clean up the StreamReader

sr.Close()

End Using

textScrape = strOutput
