ruby-on-rails - Ruby API 请求中的 Yahoo Oauth - 签名无效

Question

我已经成功获得访问 token 和访问密码。现在，我正在尝试使用 OAuth 信息发出 API 请求。

我正在关注雅虎文档(不是很有帮助): https://developer.yahoo.com/oauth/guide/oauth-make-request.html https://developer.yahoo.com/oauth/guide/oauth-signing.html

此外，我正在尝试密切关注此示例: https://gist.github.com/cheenu/1469815

这是代码:(为了方便，我把长 url 分开了)

require 'cgi'
require 'base64'
require 'openssl'

url = "http://fantasysports.yahooapis.com/fantasy/v2/game/nfl"
parameters = "format=json
  &realm=yahooapis.com
  &oauth_consumer_key=#{Rails.application.secrets.yhoo_consumer_key}
  &oauth_nonce=#{SecureRandom.hex}
  &oauth_signature_method=HMAC-SHA1
  &oauth_timestamp=#{Time.now.to_i}
  &oauth_token=#{ApiVar.final_oauth_token} #the access token
  &oauth_version=1.0"

base_string = 'GET&' + CGI.escape(url) + '&' + CGI.escape(parameters)

oauth_signature = CGI.escape(Base64.encode64("#{OpenSSL::HMAC.digest('sha1', ApiVar.final_oauth_secret + "&", base_string)}").chomp)

#ApiVar.final_oauth_secret is the access token secret - is that what I should be putting there?

testable_url = url + '?' + parameters + '&oauth_signature=' + oauth_signature
p testable_url
response = HTTParty.get(testable_url)

我的回复是“signature_invalid”。

我做错了什么？

谢谢!

Answer 1

    url = "http://fantasysports.yahooapis.com/fantasy/v2/league/{league-key}/players"
    parameters = "format=json&oauth_consumer_key=#{Rails.application.secrets.yhoo_consumer_key}&oauth_nonce=#{SecureRandom.hex}&oauth_signature_method=HMAC-SHA1&oauth_timestamp=#{Time.now.to_i}&oauth_token=#{ApiVar.final_oauth_token}&oauth_version=1.0&realm=yahooapis.com"
    base_string = 'GET&' + CGI.escape(url) + '&' + CGI.escape(parameters)
    secret = "#{Rails.application.secrets.yhoo_consumer_secret}&#{ApiVar.final_oauth_secret}"
    oauth_signature = CGI.escape(Base64.encode64("#{OpenSSL::HMAC.digest('sha1', secret, base_string)}").chomp)
    testable_url = url + '?' + parameters + '&oauth_signature=' + oauth_signature
    p testable_url
    response = HTTParty.get(testable_url)

#{Rails.application.secrets.yhoo_consumer_secret}&#{ApiVar.final_oauth_secret}" - correct secret key 

参数必须按字母顺序排列!另外，秘钥是yahoo consumer secret加上最终的oauth secret!
