Can Powershell be used to list the contents of a URL directory?

问题

We have a bunch of zip files hosted on an FTP server, which are also accessible via HTTP. I would love to do something like (gci http://test.com/test/ *.zip ) and give me all the zip files which exist on the webserver.

Does anyone know of a way to do such a thing in a clean way?

TIA

回答1:

this is quite easy with invoke-webrequest (PS V3)

$r=iwr http://asite.com/test2/ -UseBasicParsing  
$r.Links |?{$_.href -match ".zip"} 

of course as +arco444 states, the directory index must be enable

Edit To get the last modified file, you will have to parse the HTML, here is an example (the regex will have to be addapted to your config) :

$col=@()
$link,$date,$size=""
$r=iwr http://asite.com/test2/ 
$r.ParsedHtml.body.getElementsByTagName('TR')|%{ 
    $_.getElementsByTagName('TD') |select -expand innerHTML |%{     
        switch -regex ($_){
            "(.)*zip"{ $link = $_;break}
            "\d{2}-...-\d{4}(.)*"{$date=$_;break}
              "^\d*[KM]"    {$size=$_;break }       
            default{}
        }

    }
        if( $link -and $date -and $size){
        $o=new-object -typename psobject |select  -property "link","date","size"
        $o.link=$link
        $o.date=$date
        $o.size=$size

        $col+=$o
        }
    } 
    $col |select -unique "link","date","size" |sort -desc date |select -last 1
