How to post PUT request under the Windows using curl?

Question

I need to post XML data via curl.exe under windows using PUT request.

In the curl help I found:

-d/--data <data>   HTTP POST data (H)

What should I supply for <data>?

Haven't used curl with this option, but according to manual, it is simply string that is passed to the server as entity body. If your data starts with '@', then what follows is name of file that will be read and sent to the server. Check man page: http://curl.haxx.se/docs/manpage.html — Peter Štibraný, Nov 23 '10 at 15:18
@Peter Štibraný Thanks! overlooked this - though that this is something specific for unix command line syntax and there is no in windows. — sergtk, Nov 23 '10 at 15:25

curl sample calls

# with inlining plain data
curl -X PUT -d "payload" http://localhost
# referrring file
curl -X PUT -d @myXmlFile.xml http://localhost

If your windows curl-port does not support it go for cygwin. It is a linux-like environment for windows and also offers "a proper" curl.

I tried cygwin and obtained error with getaddrinfo. Ran on other PC - all ok. – sergtk Nov 25 '10 at 23:48
so this then looks like a problem with your machine or network stack? The other PC which OS is it, also windows? – manuel aldana Nov 26 '10 at 10:38
I struggled with posting data payload from file on windows too and in the end I found my data file was in UTF8 (starting with FF FE bytes) so I had to use `--data-binary` instead of just `-d` (which is alias for `--data`). – eXavier Mar 03 '14 at 12:31
on Windows PowerShell curl refers to Invoke-WebRequest which does not work as expected because it has a different syntax. Instead curl.exe is the Windows equivalence of Unix curl command and works as expected. – Saeed Mohtasham Jun 27 '22 at 12:14

in windows you'll need to put the @ inside the quotes for the file you're sending:

curl -XPUT --data-binary "@uploadme.txt"

otherwise you'll get weird errors as it tries to use the content of the file as the url:

curl: (6) Couldn't resolve host 'upload'
curl: (6) Couldn't resolve host 'me!'

(uploadme.txt contains "upload me!")

It was the putting of the @ insde the quotes that's had me guessing for hours. Thanks Paul – Martin Parry Apr 12 '17 at 02:09

Thanks for specifying that the @ needed to be put inside the quotes. I've been banging my head on the keyboard for the past few hours trying to figure this out. Thanks again – Mike Barlow - BarDev Oct 06 '17 at 19:09

In windows, if a double-quoted argument itself contains a double quote character, the double quote must be doubled.

For example, enter 'This is "quoted" payload' as "This is ""quoted"" payload" which is very different than in Unix.

Example:

curl -X PUT -d "This is ""quoted"" payload" http://localhost

on Windows CMD, curl refers to C:\Windows\System32\curl.exe so you can use

curl -X PUT -d "payload" http://localhost

instead on Windows PowerShell curl refers to Invoke-WebRequest so it is not working with curl syntax. you can use curl.exe on PowerShell to call C:\Windows\System32\curl.exe so it will solve the issue.

curl.exe -X PUT -d "payload" http://localhost
