获取我的网站访问者的 Facebook 用户 ID，无需身份验证 [英] Get Facebook User Id of my website visitors w/o auth

问题描述

有什么方法可以通过使用 FB API 获取我网站中访问者的 Facebook 用户 ID，而无需要求他们对我的 Facebook 应用进行身份验证?

Is there any way to get the Facebook User Id of visitors in my website by using the FB API, but without need to ask them to authenticate my Facebook app?

我只需要一些与 facebook 相关的标识符，它甚至不必是用户 ID，而是可以将用户与 facebook 个人资料相关联的任何类型的标识符.

All I need is some facebook-related-identifier, it does not even have to be the User Id, but any kind of identifier that can relate the user to a facebook profile.

想法?

推荐答案

如果用户没有明确授权您从他的 Facebook 帐户(包括他的 Facebook ID)获取一些私人数据，您将无法获取它们.

If the user does not explicitly authorize you to get some private data from his Facebook account (included his Facebook ID), you can not get them.

我想不出办法在没有用户授权的情况下获取 Facebook ID.

I cannot think of a way to get the Facebook ID without the authorization of the user.
