Create a post request on ruby, based on a php version - php

Question

i was away from Ruby for a while...now, i need to recreate a php api connection (curl) on ruby, to add it to my rails app, but all im getting is a Net::HTTPMovedPermanently message
here is the original php version:
$url = "https://marketplace.walmartapis.com/v3/token";
$uniqid = uniqid();
$authorization_key = base64_encode($client_id.":".$client_secret);
$code = "";
$ch = curl_init();
$options = array(
"WM_SVC.NAME: Walmart Marketplace",
"WM_QOS.CORRELATION_ID: $uniqid",
"Authorization: Basic $authorization_key",
"Accept: application/json",
"Content-Type: application/x-www-form-urlencoded",
),
);
curl_setopt_array($ch,$options);
$response = curl_exec($ch);
$code = curl_getinfo($ch,CURLINFO_HTTP_CODE);
curl_close($ch);
if($code == 201 || $code == 200)
{
$token = json_decode($response,true);
return $token['access_token'];
}
}
And this is my Ruby version so far:
require 'net/http'
require 'base64'
client_id = "id"
client_secret = "secret"
url = "https://marketplace.walmartapis.com/v3/token/"
uniqid = "1234567890abc"
uri = URI(url)
request = Net::HTTP::Post.new(uri)
request['WM_SVC.NAME'] = 'Walmart Marketplace'
request['WM_QOS.CORRELATION_ID'] = uniqid
request.basic_auth(client_id, client_secret)
request['Accept'] = 'application/json'
request['Content-Type'] = 'application/x-www-form-urlencoded'
http = Net::HTTP.new(uri.host)
response = http.request(request)
puts response
What im missing?
Update...
i've changed some things based on curl-to-ruby web, and is at follows...now im getting a 400 error
require 'net/http'
require 'uri'
client_id = "foo"
client_secret = "bar"
url = "https://marketplace.walmartapis.com/v3/token"
uniqid = "1234567890abc"
uri = URI.parse(url)
request = Net::HTTP::Post.new(uri)
request["WM_SVC.NAME"] = "Walmart Marketplace"
request["WM_QOS.CORRELATION_ID"] = uniqid
request.basic_auth(client_id, client_secret)
request["Accept"] = "application/json"
request.content_type = "application/x-www-form-urlencoded"
req_options = {
use_ssl: uri.scheme == "https",
}
response = Net::HTTP.start(uri.hostname, req_options) do |http|
http.request(request)
end
puts response.code
puts response.body
i created a new question to clear out whats working so far, and the missing fields comparing to php

It looks like the resource you are trying to access has been moved. The HTTPMovedPermanently reponse is a form of HTTPRedirection. Your code should make another request to the new location.
This is the example directly from the Net::HTTP documentation:
def fetch(uri_str, limit = 10)
# You should choose a better exception.
raise ArgumentError, 'too many HTTP redirects' if limit == 0
response = Net::HTTP.get_response(URI(uri_str))
case response
when Net::HTTPSuccess then
response
when Net::HTTPRedirection then
location = response['location']
warn "redirected to #{location}"
fetch(location, limit - 1)
else
response.value
end
end
