Ruby on rails TwitterOAuth:：未经授权的400错误请求，正在执行RailsApps OAuth教程

我正在学习RailsApps Oauth教程，在访问/auth/Twitter时，我不知道如何避免收到Twitter Oauth:：Unauthorized 400错误请求

一切都一模一样

花了好几个小时在谷歌上搜索，多种不同的回调url，放置不同的环境变量

    self.token_request(http_method, uri.path, token, request_options, arguments)
  when (400..499)
    raise OAuth::Unauthorized, response
  else
    response.error!
  end

非常感谢你的帮助，只想继续学习

您是否审查了OmniAuth回购协议的问题？也许你可以在那里提出一个问题。您的回调url应该是：

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :twitter, ENV['TWITTER_KEY'], ENV['TWITTER_SECRET'],
end

Rails.application.config.middleware.use OmniAuth::Builder do
  provider :twitter, 'TWITTER_KEY', 'TWITTER_SECRET'
end
