Wget аналог для windows 10

I know I can download and install the aformentioned library (wget for Windows), but my question is this:

In Windows PowerShell, is there a native alternative to wget?

I need wget simply to retrieve a file from a given URL with HTTP GET. For instance:

wget http://www.google.com/

PowerShell V4 One-liner:

(iwr http://blog.stackexchange.com/).Content >index.html`

or

(iwr http://demo.mediacore.tv/files/31266.mp4).Content >video.mp4

This is basically Warren’s (awesome) V3 one-liner (thanks for this!) — with just a tiny change in order to make it work in a V4 PowerShell.

Warren’s one-liner — which simply uses wget rather than iwr — should still work for V3 (At least, I guess; didn’t tested it, though). Anyway. But when trying to execute it in a V4 PowerShell (as I tried), you’ll see PowerShell failing to resolve wget as a valid cmdlet/program.

For those interested, that is — as I picked up from Bob’s comment in reply to the accepted answer (thanks, man!) — because as of PowerShell V4, wget and curl are aliased to Invoke-WebRequest, set to iwr by default. Thus, wget can not be resolved (as well as curl can not work here).

If your Windows is new enough (like version 1809 or newer), there’s a «real» curl available. curl has the command-Line option «-O» (capital letter O; small letter won’t do the same!) The option «-O», alternatively «—remote-name» tells curl, that the saved file gets the same name as the file-name part of the URL.

One needs to start this as «curl.exe», to discern it from the Alias «curl» for «Invoke-WebRequest». Incidentally it works in cmd.exe without changes.

Using the same example as in another answer here

curl.exe -O http://demo.mediacore.tv/files/31266.mp4

(The site won’t allow me to add this as a comment, since I apparently need more «reputation» for that — so it gets a new answer)

Here is a PowerShell function that resolves short URLs before downloading the file

function Get-FileFromUri {  
    param(  
        [parameter(Mandatory=$true, Position=0, ValueFromPipeline=$true, ValueFromPipelineByPropertyName=$true)]
        [string]
        [Alias('Uri')]
        $Url,
        [parameter(Mandatory=$false, Position=1)]
        [string]
        [Alias('Folder')]
        $FolderPath
    )
    process {
        try {
            # resolve short URLs
            $req = [System.Net.HttpWebRequest]::Create($Url)
            $req.Method = "HEAD"
            $response = $req.GetResponse()
            $fUri = $response.ResponseUri
            $filename = [System.IO.Path]::GetFileName($fUri.LocalPath);
            $response.Close()
            # download file
            $destination = (Get-Item -Path ".\" -Verbose).FullName
            if ($FolderPath) { $destination = $FolderPath }
            if ($destination.EndsWith('\')) {
                $destination += $filename
            } else {
                $destination += '\' + $filename
            }
            $webclient = New-Object System.Net.webclient
            $webclient.downloadfile($fUri.AbsoluteUri, $destination)
            write-host -ForegroundColor DarkGreen "downloaded '$($fUri.AbsoluteUri)' to '$($destination)'"
        } catch {
            write-host -ForegroundColor DarkRed $_.Exception.Message
        }  
    }  
}  

Use it like this to download the file to the current folder:

Get-FileFromUri http://example.com/url/of/example/file  

Or to download the file to a specified folder:

Get-FileFromUri http://example.com/url/of/example/file  C:\example-folder  

The following function will get a URL.

function Get-URLContent ($url, $path) {
  if (!$path) {
      $path = Join-Path $pwd.Path ([URI]$url).Segments[-1]
  }
  $wc = New-Object Net.WebClient
  $wc.UseDefaultCredentials = $true
  $wc.Proxy.Credentials = $wc.Credentials
  $wc.DownloadFile($url, $path)
}

Some comments:

1. The last 4 lines are only needed if you are behind an authenticating proxy. For simple use, (New-Object Net.WebClient).DownloadFile($url, $path) works fine.
2. The path must be absolute, as the download is not done in your current directory, so relative paths will result in the download getting lost somewhere.
3. The if (!$path) {...} section handles the simple case where you just want to download the file to the current directory using the name given in the URL.

PowerShell Invoke-RestMethod may have fewer dependencies than other methods … in case you have a minimal (or older) Windows Server installed.

See error reported at Running Invoke-WebRequest as System account:

Invoke-WebRequest : The response content cannot be parsed because the
Internet Explorer engine is not available, or Internet Explorer’s
first-launch configuration is not complete. Specify the
UseBasicParsing parameter and try again.

This can be an alternative to applying the -UseBasicParsing option that is, in some cases, required with wget or Invoke-WebRequest.

However, the displayed response may be in a different format, based on data parsing:

PowerShell formats the response based to the data type. For an RSS or
ATOM feed, PowerShell returns the Item or Entry XML nodes. For
JavaScript Object Notation (JSON) or XML, PowerShell converts, or
deserializes, the content into [PSCustomObject] objects.

I come from a Linux/Unix background and I have been wondering if Windows has a binary that can download files from the console.

I would like to automate a certain process and one of my requirements it to not install much software, but use the built-in stuff as much as possible.

Thanks!

I like http-ping utility. You can run with these settings:
ping once and save the contents to google.html

http-ping.exe -n 1 http://www.google.com/ -f google.html

It does not require installation. Check more about http-ping here
