Rails omniauth 获得真正的 Facebook 个人资料链接

Question

我想获得一个真正的 Facebook 链接。 因此，在使用 Omniauth Gem 进行身份验证后，我的链接如下： https://www.facebook.com/app_scoped_user_id/960601127305294/ 但我的真实个人资料链接是：https://www.facebook.com/kuzevanoff

所以对于我的系统，有两个不同的链接。

我该如何解决我的问题？

谢谢！

我的 Omniauth 哈希：

如果您使用的是omniauth-facebook gem，那么您将获得以下身份验证哈希request.env['omniauth.auth']

# Example from omniauth-facebook gem
# https://github.com/mkdynamic/omniauth-facebook#auth-hash
{
  :provider => 'facebook',
  :uid => '1234567',
  :info => {
    :nickname => 'jbloggs',
    :email => 'joe@bloggs.com',
    :name => 'Joe Bloggs',
    :first_name => 'Joe',
    :last_name => 'Bloggs',
    :image => 'http://graph.facebook.com/1234567/picture?type=square',
    :urls => { :Facebook => 'http://www.facebook.com/jbloggs' },
    :location => 'Palo Alto, California',
    :verified => true
  },
  # Removed non-essential part for brevity..
}

您可以通过 info > urls > Facebook 看到个人资料网址。此外，您可以将昵称附加到根 url 以获取配置文件链接。

"http://www.facebook.com/" + omniauth_hash.info.nickname
