curl - How to set Content-Length header at command line?

Im using the curl command line tool. I do something like

curl -XPUT "https://example.org?p1=value1&p2=value2" -H"Content-Type:application/x-www-form-urlencoded"

The server replies with

HTTP/1.1 411 Length Required

The solution is usually to set the appropriate Content-Length header.

But what is the Content-Length in this case and how to set it with curl?

By default curl sets appropriate Content-Length header for you when data is provided with -d parameter. In your case the server seems to wait for some data in the body. But for some reason you decided to pass the data in the url.

1. Simple Solution

Add -d"" to the command. This will cause curl to set the appropriate length to 0. You could also set the appropriate header to -H"Content-Length:0"

2. Why transport data as query parameters?

Try instead: curl -XPUT -d'p1=value1\np2=value2' https://example.org
