推送到 heroku 后出现 500 错误 - DEBUG

Question

我在生产时遇到 openuri 问题。下面的代码在开发中有效，但在生产中出现未经授权的错误。我解决这个问题的唯一方法是将 api 键直接放在 url 中，显然我不想这样做。知道为什么我当前的代码不起作用吗？

 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 returns 一个 401 错误，我的猜测是 ENV['NEWS_API'] 未设置。您可以在终端中运行 heroku config 或在 Web 界面上查找：Settings -> Reveal Config Vars

推送到 heroku 后出现 500 错误 - DEBUG

500 error after pushing to heroku - DEBUG

ruby-on-rails

heroku

migration

open-uri
