Question

如何处理用户撤销对其LinkedIn帐户的访问权限？我使用Ruby on Rails与Omniauth，Omniauth-LinkedIn和linkedin gem（后者合并oauth gem）。

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
