Linkedin Share Api using simple curl - api

Question

I do a simple request to share something on my linkedin profile
I try to just do it with curl but it doesn't work
I set the content-type to JSON in the header and I also set the authorization in the header
curl -v -H 'Authorization: OAuth oauth_consumer_key="V9uKPtEEB7JxQvYzbR2DuDfLe4qXjASgP5UhPJp8k13CYgSnN3BRFILxUJ6ApuCH",oauth_token="d6af5cda-b46e-4c38-b566-11428a9584fc",oauth_signature_method="HMAC-SHA1",oauth_signature="1PofnBExFc7pMB8b08fV34B5sTg%3D",oauth_timestamp="1323544645",oauth_nonce="516e0a1eadda4c24bfbcc4ca5e0cbedc",oauth_version="1.0"' -H 'Content-Type: application/json' -X POST -d '{"recipients":{"values": [{"person":{"_path": "/people/~"}}]}, "subject": "JSON POST test", "body": "You rule"}' http://api.linkedin.com/v1/people/~/shares
When I post this I get this result
