【宋词】《南浦》 孔夷：风悲画角，听单于、三弄落谯门。投宿征骑，飞雪满孤村。酒市渐闲灯火，正敲窗、乱叶舞纷纷。送数声惊雁，下离烟水，嘹唳度寒云。

2、获取 Invoke-WebRequest 的相关帮助文档。执行命令：get-help invoke-webrequest

Plaintext

PS E:\wwwroot> get-help invoke-webrequest                                             
是否要运行 Update-Help?
Update-Help cmdlet 下载 Windows PowerShell 模块的最新帮助文件，并将其安装在你的计算机 上。有关 Update-Help cmdlet
 的详细信息，请参阅 https:/go.microsoft.com/fwlink/?LinkId=210614。

名称
    Invoke-WebRequest

摘要
    Gets content from a web page on the Internet.


语法
    Invoke-WebRequest [-Uri]  [-Body ] [-Certificate ] [-CertificateThumbpri
    nt ] [-ContentType ] [-Credential ] [-DisableKeepAlive] [-Headers ] [-InFile ] [-MaximumRedirection ] [-Metho
    d {Default | Get | Head | Post | Put | Delete | Trace | Options | Merge | Patch}]
     [-OutFile ] [-PassThru] [-Proxy ] [-ProxyCredential <
    System.Management.Automation.PSCredential>] [-ProxyUseDefaultCredentials] [-Sessi
    onVariable ] [-TimeoutSec ] [-TransferEncoding {chun
    ked | compress | deflate | gzip | identity}] [-UseBasicParsing] [-UseDefaultCrede
    ntials] [-UserAgent ] [-WebSession ] []


说明
    The `Invoke-WebRequest` cmdlet sends HTTP, HTTPS, FTP, and FILE requests to a web
     page or web service. It parses the response and returns collections of forms, li
    nks, images, and other significant HTML elements.

    This cmdlet was introduced in Windows PowerShell 3.0.

    > [!NOTE] > By default, script code in the web page may be run when the page is b
    eing parsed to populate the > `ParsedHtml` property. Use the `-UseBasicParsing` s
    witch to suppress this.

    > [!IMPORTANT] > The examples in this article reference hosts in the `contoso.com
    ` domain. This is a fictitious > domain used by Microsoft for examples. The examp
    les are designed to show how to use the cmdlets. > However, since the `contoso.co
    m` sites do not exist, the examples do not work. Adapt the examples > to hosts in
     your environment.
