Interagieren mit Yahoo -Tischler in Ruby

Question

Ich versuche zu benutzen net/http mit der Yahoo -Tischemacher -API zu interagieren, aber ich kann es nicht zum Laufen bringen. Hier ist, was ich bisher habe:

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}"

Dies gibt mir den folgenden Fehler:

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>'

Nachdem ich den @host typo behoben habe, bekomme ich jetzt:

Response 400 Bad Request:
<?xml version="1.0" encoding="UTF-8" ?>
<yahoo:error xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" xmlns:cle="http://wherein.yahooapis.com/v1/schema.rng" xmlns:xml="http://www.w3.org/XML/1998/namespace" xml:lang="en"><yahoo:description><![CDATA[Please provide a document URL or content.]]></yahoo:description>
<yahoo:detail><code>-9999</code>

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

Answer 1

Sie schicken ihnen JSON und sie scheinen nach einer regelmäßigen Abfragebrunde im Postkörper zu suchen. Sie sollten auch HTTParty verwenden, um Webdienste zu konsumieren, es sei denn, Sie haben einen guten Grund, nicht:

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

Möglicherweise nur ein Tippfehler? @host sollte sein host Rechts?
