我正在尝试使用net/httpYahoo Placemaker API 进行交互，但我似乎无法让它工作。这是我到目前为止所拥有的：

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}"

这给了我以下错误：

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>'

修复 @host 错字后，我现在得到：

Response 400 Bad Request:

您正在向他们发送 json，他们似乎正在寻找帖子正文中的常规查询字符串。此外，您可能应该使用 httparty 来使用 Web 服务，除非您有充分的理由不这样做：

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'}

可能只是一个错字？@host应该是host对的？
