Artifactory AQL post over ruby - ruby

Question

I'm trying to query the Artifactory's AQL API using ruby code, I already checked that this code works on bash using curl:
curl -u admin:password -i -H "Accept: application/json" -X POST http://server.example.com:8081/artifactory/api/search/aql -T aql.aql
Where aql.aql contents are as follows:
items.find
(
{
"repo":{"$eq":"test-ASO"}
}
)
.include("name","property.*")
Now I'm trying to do the same using Ruby with this code:
#!/usr/bin/ruby
require 'rubygems'
require 'json'
require 'open-uri'
require 'uri'
require 'net/http'
payload ='items.find
(
{
"repo":{"$eq":"test-ASO"}
}
).include("name","property.*")'
uri = URI.parse("http://server.example.com:8081/artifactory/api/search/aql")
http = Net::HTTP.new(uri.host,uri.port)
req = Net::HTTP::Post.new(uri.path)
req.basic_auth 'user', 'password'
req.set_form_data(payload)
res = http.request(req)
puts res.body
But all that I get is:
{
"errors" : [ {
"status" : 400,
"message" : "Bad Request"
} ]
}
My guess is that the payload of the query has to be a file, as I did before with curl (-T parameter) but I don't think that using files for queries is a very elegant way to achieve this.

EDIT
Finally I achieved this by declaring the req.body variable with the proper content:
#!/usr/bin/ruby
require 'rubygems'
require 'json'
require 'open-uri'
require 'uri'
require 'net/http'
payload = 'items.find().include("name","property.*")'
uri = URI.parse("http://server.example.com:8081/artifactory/api/search/aql")
http = Net::HTTP.new(uri.host,uri.port)
req = Net::HTTP::Post.new(uri.path)
req["Content-Type"] = "text/plain"
req.basic_auth 'admin', 'password'
req.body = payload
res = http.request(req)
puts res.body
