将应用程序部署到Heroku后出现错误。在当地它工作正常。我正在使用Sinatra和Wordnik API。
以下是代码：
require 'rubygems'
require 'sinatra'
require 'haml'
require 'json'
require 'wordnik'
Wordnik.configure do |config|
config.api_key = '6bdddbf6a24e7dbdf400407f4670ff071b7d92089d30451b1'
end
get '/word' do
resp = Wordnik.words.get_random_word(:hasDictionaryDef => 'true', :maxCorpusCount => 20, :minLength => 10)
result = JSON.parse(resp.to_json)
word = result["word"]
return word.to_s
end
heroku日志输出：
