PowerShell equivalent of curl
Is there an equivalent of curl
in PowerShell? Does it have some similar built-in capability or is there a 3rd party cmdlet?
Solution 1:
PowerShell 3.0 has the new command Invoke-RestMethod
:

Solution 2:
As of Powershell 5.0, if not before, curl
is an alias for Invoke-WebRequest
.
PS> Get-Alias -Definition Invoke-WebRequest | Format-Table -AutoSize
CommandType Name Version Source
----------- ---- ------- ------
Alias curl -> Invoke-WebRequest
Alias iwr -> Invoke-WebRequest
Alias wget -> Invoke-WebRequest
To use the unaliased command ...
PS> Invoke-WebRequest -Uri https://localhost:443/
PS> Invoke-WebRequest -Uri https://www.google.com
So return several properties of the request as follows ...
PS> Invoke-WebRequest -Uri https://www.google.com
StatusCode : 200
StatusDescription : OK
Content : <!doctype html><html itemscope="" itemtype="http://schema.org/WebPage" lang="en-AU"><head><meta content="text/html; charset=UTF-8"
http-equiv="Content-Type"><meta content="/images/branding/googleg/1x/...
RawContent : HTTP/1.1 200 OK
X-XSS-Protection: 1; mode=block
X-Frame-Options: SAMEORIGIN
Vary: Accept-Encoding
... or just the content ...
PS> Invoke-WebRequest -Uri https://www.google.com | Select-Object -ExpandProperty Content
<!doctype html><html itemscope="" itemtype="http://schem[etc ...]
The equivalent aliased commands are ...
PS> curl -Uri https://www.google.com
PS> curl -Uri https://www.google.com | Select-Object -ExpandProperty Content
Leveraging Powershell defaults and other aliases you could shorten the commands to
PS> curl https://www.google.com
ps> curl https://www.google.com | Select -ExpandProperty Content
... but I wouldn't recommend it. Verbose commands help others when reading your code.
Update:
Powershell 6.x
Use of Aliases discouraged
As of Powershell 6.x "Core" curl
is no longer an alias for Invoke-WebRequest
(the alias wget
is also removed) . Instead use Invoke-WebRequest
directly.
PS> Get-Alias -Definition Invoke-WebRequest | Format-Table -AutoSize
CommandType Name Version Source
----------- ---- ------- ------
Alias iwr -> Invoke-WebRequest
Curl is no longer an alias for Invoke-WebRequest (tested on Powershell 6.2.3), despite an apparent rejection of a motion in an RFC "to to remove the aliases curl and wget from Windows PowerShell".
That RFC notes "The wget/curl aliases were already removed from PowerShell Core so the problem [of having those aliases] was limited to Windows PowerShell."
In the conclusion the Powershell team also encourages users "to not rely on aliases in scripts".
As @v6ak has noted in the comments using curl
and wget
in PowerShell (5.0 or lower) can be a problem in: unintentionally invoking the real curl or wget if installed side-by-side; and, in any case, causes confusion.
New Encoding
It is recommended you upgrade Powershell "core" (6.x or above) in order to take advantage of the default encoding utf8NoBOM
, when using Invoke-WebRequest
(and many other text outputting commands). If one was doing this explicitly you could do something like:
Invoke-WebRequest `
-Uri https://raw.githubusercontent.com/fancyapps/fancybox/master/dist/jquery.fancybox.min.js `
| Select-Object -ExpandProperty Content `
| Out-File jquery.fancybox.min.js `
-Encoding utf8NoBOM
However, even when using a shorter, implicit, command ...
Invoke-WebRequest `
-Uri https://raw.githubusercontent.com/fancyapps/fancybox/master/dist/jquery.fancybox.min.js `
-OutFile jquery.fancybox.min.js
... encoding with utf8NoBOM
will be done (you can verify this, for example, by opening the saved file in Visual Studio Code and observing "UTF-8" in the status bar).
Files saved with utf8NoBOM
tend to cause fewer problems when traveling through various ecosystems. Of course, if you need some other encoding you can set some alternative explicitly.
In Powershell 5.0 and lower the utf8NoBOM
encoding was not available, let alone the default.
