Ruby on rails Omniauth用户值返回null

我正在用rails和Angular制作一个应用程序。用户通过Spotify进行身份验证，搜索音乐，将音乐添加到播放列表（制作播放列表），然后将该信息存储在PostgreSQL中。我对所有这些数据制作了一个API，并以角度显示

我已经能够让音乐+音乐搜索功能正常工作。我正在努力创建一个用户和用户模型，但在会话和验证用户时，我做得不对。我被重定向到正确的路径，没有看到任何错误，但我的代码返回

{

"display_name": null,
"email": null,
"images": null,
"product": null,
"external_urls": null,
"href": null,
"id": null,

"uri": null
}

我还注意到，我没有从Spotify收到

uid

。当我跑的时候

render:text=>“”+env[“omniauth.auth”]。发送到_yaml并返回

@spotify_user = RSpotify::User.new
render :json => @spotify_user

---

在我的

会话#create

中，它返回了信息，但

uid

为空。作为参考，我能使用的唯一指南是。我已经有一段时间遇到这个问题了，我知道我很快就能解决它了，因为我最终没有错误，并且可以看到数据。如果有人以前做过这样的事情，能给我指出正确的方向，我将不胜感激。谢谢你的帮助

您将应用程序的

用户

s与Spotify gem的

RSpotify:：User

s混淆了

当用户注册OmniAuth时，必须将其保存到数据库中。然后，在UsersController中，您必须找到该用户并将其作为json发送

看看你在这里做什么：

---

您正在创建一个新用户（每个属性都为nil），然后将其呈现为json。

谢谢。会话控制器和用户模型与Rspotify没有交互？它只是在数据库中保存rspotify用户信息？如果我删除rspotify并将其设置为

@spotify\u user=user.new

，然后将其余代码保持原样？对不起，我想我把它复杂化了。。。
