Using Ruby + OAuth to access Yelp API

I just getting started with OAuth, and I tried to make a small client to connect to some webservices... I tried twitter and it worked like a charm, however, I also tried to access Yelp V2 API (following their Python example) 开发者_运维百科but I always get back as an answers: HTTP 400 Bad Request

Missing parameter: oauth_consumer_key

Here's my code:

require 'rubygems'
require 'oauth'

CONSUMER_KEY = "MY_CONSUMER_KEY"
SECRET = "MY_CONSUMER_SECRET"
TOKEN = "MY_TOKEN"
TOKEN_SECRET = "MY_TOKEN_SECRET"


consumer = OAuth::Consumer.new( CONSUMER_KEY,SECRET, {:site => "http://api.yelp.com", :signature_method => "HMAC-SHA1", :scheme => :header})

access_token = OAuth::AccessToken.new( consumer, TOKEN,TOKEN_SECRET)

p access_token.get("/v2/search?location=new+york").body

Regardless to say, that code works with twitter API without any problem (I actually followed twitter's example code)

Cheers and thanks in advance, Ze

Use :query_string instead of :header and everything will work (at least for me).

Same code, using Signet:

require 'signet/oauth_1/client'
client = Signet::OAuth1::Client.new(
  :consumer_key =>        'MY_CONSUMER_KEY',
  :consumer_secret =>     'MY_CONSUMER_SECRET',
  :access_token_key =>    'MY_TOKEN_KEY',
  :access_token_secret => 'MY_TOKEN_SECRET'
)
response = client.fetch_protected_resource(
  :uri => 'http://api.yelp.com/v2/search?location=new+york'
)
# The Rack response format is used here
status, headers, body = response
p body

As per the Yelp documentation, the OAuth parameters do not have to be passed in the query string. The fact that the accepted answer resolved the issue indicates to me that there's probably a bug in the oauth gem causing this.
