ruby-on-rails - 如何在 Rails 中处理用户撤销 LinkedIn 访问权限

Question

我应该如何处理用户撤销我对其 LinkedIn 帐户的访问权限？我正在使用 Ruby on RailsOmniauth和gem Omniauth-LinkedIn（linkedin后者包含oauthgem）。

我的控制器代码

if !@user[:lnk_token].nil?
  client = LinkedIn::Client.new("xxxx","xxxx")
  client.authorize_from_access(@user[:lnk_token].strip,@user[:lnk_access_token_secret].strip)
  @lnk = client.profile(:fields => ["picture-url", "positions", "educations"])
end

Answer 1

使用简单的错误处理程序：

if !@user[:lnk_token].nil?
  client = LinkedIn::Client.new("xxxx","xxxx")
  client.authorize_from_access(@user[:lnk_token].strip,@user[:lnk_access_token_secret].strip)
  begin
    @lnk = client.profile(:fields => ["picture-url", "positions", "educations"])
  rescue
    @lnk = nil
  end
end
