使用http的Windows文件复制

Question

是否有windows命令将文件从http url复制或下载到文件系统？我试过复制,xcopy和robocopy,他们似乎不支持http网址.

您可以使用powershell脚本来完成此任务.
Get-Web http://www.msn.com/ -toFile www.msn.com.html

function Get-Web($url, 
    [switch]$self,
    $credential, 
    $toFile,
    [switch]$bytes)
{
    #.Synopsis
    #    Downloads a file from the web
    #.Description
    #    Uses System.Net.Webclient (not the browser) to download data
    #    from the web.
    #.Parameter self
    #    Uses the default credentials when downloading that page (for downloading intranet pages)
    #.Parameter credential
    #    The credentials to use to download the web data
    #.Parameter url
    #    The page to download (e.g. www.msn.com)    
    #.Parameter toFile
    #    The file to save the web data to
    #.Parameter bytes
    #    Download the data as bytes   
    #.Example
    #    # Downloads www.live.com and outputs it as a string
    #    Get-Web http://www.live.com/
    #.Example
    #    # Downloads www.live.com and saves it to a file
    #    Get-Web http://wwww.msn.com/ -toFile www.msn.com.html
    $webclient = New-Object Net.Webclient
    if ($credential) {
        $webClient.Credential = $credential
    }
    if ($self) {
        $webClient.UseDefaultCredentials = $true
    }
    if ($toFile) {
        if (-not "$toFile".Contains(":")) {
            $toFile = Join-Path $pwd $toFile
        }
        $webClient.DownloadFile($url, $toFile)
    } else {
        if ($bytes) {
            $webClient.DownloadData($url)
        } else {
            $webClient.DownloadString($url)
        }
    }
}

我不熟悉Windows上可以执行此操作的任何命令,但我总是在Windows上下载GNU wget用于这些和类似目的.
