Question

生产中出现openuri问题。以下代码在开发中可用，但在生产中会出现未经授权的错误。我解决此问题的唯一方法是，如果我将api键直接放在url中，显然我不想这样做。任何想法为何我当前的代码不起作用？

 api_key = ENV["NEWS_API"]
 url = "https://newsapi.org/v2/top-headlines?sources=techcrunch&apiKey=#{api_key}"
 article_serialized = open(url).read
@articles = JSON.parse(article_serialized)

OpenURI返回401错误，我的猜测是未设置ENV['NEWS_API']。您可以在终端中运行heroku config或在Web界面上查找它：Settings-> Reveal Config Vars

推送到heroku后出现500错误-调试
