Making a POST request with Chef - ruby

Question

I need to post a .json file to a server with a rest API with a Chef recipe, following Chef's documentation I came up with this code:
http_request '/tmp/bpp.json' do
url 'http://localhost:8080/api/v1/blueprints/bpp'
headers ({
'AUTHORIZATION' => "Basic #{Base64.encode64(user)}",
'CONTENT-TYPE' => 'aplication/json'
})
action :post
end
For authorization token, user is a variable that contains 'user:password'
When I run this chef recipe I obtain the following response:
Error executing action `post` on resource 'http_request[POST /tmp/bpp.json]'
Net::HTTPServerException
------------------------
400 "Bad Request"
Prior to this I was just executing a curl call and it was working fine, but I need to change to the http_request resource. This was the old (working) curl request:
curl --user user:password -H 'X-Requested-By:My-cookbook' --data #/tmp/bpp.json localhost:8080/api/v1/blueprints/bpp
I am not very used with REST apis and seems like an uncharted territory to me.

You forget about message. Using file name as resource name won't send this file as data. Try adding:
...
message lazy { IO.read('/tmp/bpp.json') }
...
In your case only the resource name - /tmp/bpp.json, will be sent. Not a file content. As stated in linked doc:
The message that is sent by the HTTP request. Default value: the name of the resource block See “Syntax” section above for more information.
