从 doorkeeper 获取“授权服务器不支持此响应类型”

Question

我正在尝试使用 devise (3.4.1) + doorkeeper (2.4.1) + Rails 4.2 构建一个 api，当我尝试连接我的前端时，我不断收到错误“授权服务器不支持此响应类型” app 这是控制台的转储：

Started GET "/oauth/authorize?response_type=token&client_id=a91f8fea40322739310b0db9ee3e3d53878bff0df073f3aa36af7da4f99b365e&redirect_uri=http%3A%2F%2Flocalhost%3A9000&scope=public&state=" for ::1 at 2015-03-28 16:12:18 -0700

  Rendered /Users/osuthorpe/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/doorkeeper-2.1.4/app/views/doorkeeper/authorizations/error.html.erb within layouts/doorkeeper/application (287.7ms)
Completed 200 OK in 460ms (Views: 406.2ms | ActiveRecord: 11.4ms | Solr: 0.0ms)

前端应用程序运行良好，我可以使用其他 oauth2 提供商进行身份验证。

我认为新版本的看门人可能会禁用一些 grant_flows。您可以通过删除grant_flows %w(authorization_code implicit password client_credentials)config/initializers/doorkeeper.rb中的注释来启用它以启用所有授权流
