如何验证一个Facebook用户的访问令牌上编程服务器端（Node.js的）？ [英] How to verify a Facebook user's access token programmatically on the server-side (Node.js)?

问题描述

我有一个Facebook用户的访问令牌，我想验证这个访问令牌是否有效，即无论是已知的Facebook，目前有效的，等等...

I have an access token by a Facebook user, and I'd like to verify whether this access token is valid, i.e. whether it is known to Facebook, currently valid, and so on…

到目前为止，我已经采取了看看Facebook的的各种的API，基本上，我什么需要的是的用户的功能得到用户的细节组合，但对于用户标识由一个访问令牌（不是他/她的ID）。

So far, I have taken a look at the various APIs of Facebook, and basically, what I need is a combination of the User functionality to get the user's details, but for a user identified by an access token (not his / her ID).

我想，不知怎的，我需要处理访问令牌API ，但作为我完全新开发Facebook应用程序，我不知道从哪里开始。

I suppose that somehow I need to deal with the access token API, but as I am completely new to developing Facebook applications, I'm not sure where to start.

基本上，我无法想象，这应该是一个相当艰巨的任务。直觉上，我期望的东西，如：

Basically, I can not imagine that this should be a quite hard task. Intuitively I'd expect something such as:

GET http://graph.facebook.com/me?accessToken=$INSERT_TOKEN_HERE

请问像这样的东西存在吗？如果是的话，可以请你点我在正确的方向？即使在什么搜索（术语，例如，）一些提示可能会有所帮助。

Does anything like this exist? If so, can you please point me in the right direction? Even a few hints on what to search for (terms, e.g.) might be helpful.

顺便说一下，此请求外壳被从服务器发送的，而不是从浏览器

By the way, this request shell be sent from a server, not from the browser.

我不知道是否是重要的，但我使用Node.js的这一点。此外，如果有哪个可以抽象的REST调用走了一个现成的模块，这也可能是有益的，有趣的。

I don't know whether it is important, but I am using Node.js for this. Additionally, if there's a ready-made module which can abstract the REST calls away, this might also be helpful and interesting.

任何想法？

推荐答案

您可以检索通过发出GET请求到 debug_token 连接与特定的访问令牌中的信息。是这样的：

You can retrieve the information related to a particular Access Token by issuing a GET request to the debug_token connection. Something like:

GET /debug_token?
     input_token={input-token}&
     access_token={access-token}

您可以得到关于它的更多信息，获取有关信息的令牌和调试参考。

You can get more information about it in the Getting Info about Tokens and Debugging reference.
