PowerShell : 如何使用PowerShell呼叫WebRequest?

節錄出程式內的function應該就能了解了:

function GoRefresh($gdString)
{
    $today = Get-Date
    write-host "更新:" $id "-->" $today

    $url = "http://192.168.1.100/refresh_html.ashx?id=" + $id
    write-host "url:" $url

    $request = [System.Net.WebRequest]::Create($url)

    $response = $request.GetResponse()
    $requestStream = $response.GetResponseStream()
    $readStream = new-object System.IO.StreamReader $requestStream
    new-variable tmp
    $tmp = $readStream.ReadToEnd()
    write-host "response:" $tmp
    $readStream.Close()
    $response.Close()
}
