Yahoo Oauth in Ruby API Request - Signature Invalid -


i have gotten access token , access secret. i'm trying make api request oauth information.

i'm following alongside yahoo docs (not helpful): https://developer.yahoo.com/oauth/guide/oauth-make-request.html https://developer.yahoo.com/oauth/guide/oauth-signing.html

also, i'm trying follow example closely: https://gist.github.com/cheenu/1469815

here code: (i split long url convenience)

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 access token secret - should putting there?  testable_url = url + '?' + parameters + '&oauth_signature=' + oauth_signature p testable_url response = httparty.get(testable_url)

my response gives me "signature_invalid."

what doing wrong?

thank you!

    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

the parameters have ordered alphabetically! also, secret key yahoo consumer secret plus final oauth secret!

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
