require 'openssl' require 'net/http'  uri =uri.parse("https://www.googleapis.com/androidpublisher/v2/applications/#{package}/reviews/#{review_id}:reply?access_token=#{access_token}") http = net::http.new(uri.host, uri.port) http.use_ssl = true http.verify_mode = openssl::ssl::verify_peer request = net::http::post.new(uri.request_uri,                   initheader = {'content-type' =>'application/json'}) request.form_data = {"replytext" => text} response = http.request(request)
