【问题描述】：

我无法为 /oauth/applications 中创建的应用程序生成访问令牌

我在门卫初始化文件中做了以下更改

doorkeeper.rb

resource_owner_authenticator do
    User.find_by_id(session[:user_id]) || redirect_to(new_user_session_url)
  end

当我尝试从 /oauth/applications 授权应用程序时，我收到以下错误

我想生成身份验证令牌以授权应用程序为我的应用程序使用 api 调用

试图在Doorkeeper 上关注railscast 剧集

这是我的application

【解决方案1】：

resource_owner_authenticator 应替换为以下块，以便为您的客户端应用程序生成身份验证令牌

resource_owner_authenticator do |routes|
 current_user || warden.authenticate!(:scope => :user)
end

【讨论】：

这行得通，你能写一两行关于这里发生的事情吗？我知道 devise 的 current_user 方法是如何替换 User.find_by_id session[:user_id] 的。
