Interacting w/ Yahoo Placemaker in Ruby

Question

I'm trying to use net/http to interact w/ the Yahoo Placemaker API but I can't seem to get it to work. Here is what I have so far:

host = 'wherein.yahooapis.com'
payload = {
    'documentContent' => 'Columbus Ohio',
    'appid' => APP_ID,
    'outputType' => 'json',
    'documentType' => 'text/plain'
}.to_json

req = Net::HTTP::Post.new('/v1/document', initheader = { 'Content-Type' =>'application/json'})
req.body = payload
response = Net::HTTP.new(host).start {|http| http.request(req) }
puts "Response #{response.code} #{response.message}: #{response.body}"

This gives me the following error:

Errno::ECONNREFUSED: Connection refused - connect(2)
    from /Users/Kyle/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/net/http.rb:762:in `initialize'

    from (irb):3
    from /Users/Kyle/.rvm/rubies/ruby-1.9.3-p0/bin/irb:16:in `<main>'

After fixing the @host typo I now get:

Response 400 Bad Request:
<?xml version="1.0" encoding="UTF-8" ?>

<yahoo:detail><code>-9999</code>

</yahoo:detail></yahoo:error>

Answer 1

You're sending them json and they seem to be looking for a regular query string in the post body. Also you should probably use httparty to consume web services unless you have a good reason not to:

require 'httparty'

class Yahoo
    include HTTParty
    base_uri 'http://wherein.yahooapis.com/'
end

json = Yahoo.post '/v1/document', :body => {:documentContent => 'Columbus Ohio', :appid => APP_ID, :outputType => 'json', :documentType => 'text/plain'}

Answer 2

Possibly just a typo? @host should be host right?
