Facebook Connect来对个人进行身份验证API [英] Facebook Connect to authenticate on a personal API

问题描述

我开发了一个简单的API，允许我的Andr​​oid / iPhone应用程序，我的服务器之间的通信。在我的应用程序，用户需要验证自己和他们这样做是使用登录/用下面的API调用密码凭据：

I have developed a simple API to allow communication between my Android/iPhone apps and my server. In my application, users need to authenticate themselves and they do it using login/password credentials with the following API call:

http://api.myapp.com/login?user=xxx&pass=pass

应用程序收到回报：

Application receives in return:

{ "api_token": "xxxx-xxxx-xxxx-xxxx" }

所以基本上我交换我的凭据对 api_token 。

我想补充的Facebook连接的支持。我已经成功地使用Facebook的SDK和接收到正确的的access_token 。

I would like to add Facebook connect support. I have successfully used the Facebook SDK and receives the correct access_token.

不过，我需要实现一种机制来交换的access_token 与 api_token

However, I need to implement a mechanism to exchange access_token with api_token

假设用户已经连他的账户与Facebook（他的网站用户面板上），这将是着手交流的最佳执行？

Assuming the user has already connected his account with Facebook (on his web user panel), what would be the best implementation to proceed to the exchange?

推荐答案

下面是如何我终于做到了。它的工作非常好一年多，从未有过任何问题。我们的想法是使用下面的API调用交换标记：

Here is how I finally did it. It's working very well for more than one year, never had any problem. The idea is to exchange tokens using the following API call:

http://api.myapp.com/login/facebook?access_token=<facebook_access_token>

服务器端，您验证的access_token 的有效性用一个简单的

wget -qO- https://graph.facebook.com/me?access_token=<facebook_access_token>

它发送回你一个JSON的所有用户信息，包括用户的Facebook ID。假设已经连他账户的Facebook用户，你可以查找在 USER_ID 并发送回一个 api_token 。
