Localhost facebook登录不适用于较低级别的URL

问题描述：

Thanks in advance for reading.

I've been working with facebook login (both php and javascript sdk methods) for a couple of years and I'm facing a particular problem with new apps I'm developing.

I have an app in my localhost configured as virtual directory as follows:

http://localhost/myapp/

On facebook, the following settings of my app are pointing to that url: App Domains, Facebook Login Website, App on Facebook (https and http) and Mobile Web.

When I do the login process and point the redirect_uri to http://localhost/myapp/, it works fine, the cookie is set and I can make queries to the graph api.

The problem comes when I try to use another redirect uri like http://localhost/myapp/user_controller/register (Adds the user to the database). Although it is inside the app url configured on facebook, the SDK outputs an error message (OAuthException | An active access token must be used to query information about the current user. | Code 2500).

I figured out that, to solve this problem for a while, I have to go to the facebook app page: apps.facebook.com/myapp. I have to do it everytime my access_token has expired and, since this app is not intended to be inside facebook, I don't think that this is the best way to solve this.

I hope together we can find a good way to solve this issue and this questions helps future developers.

I'm using CodeIgniter (which I've been using about a year) and Facebook PHP SDK (downloaded directly from the github official repo) as CI library.

Thanks again.

提前感谢您的阅读。 p>

我一直在与Facebook合作登录（php和javascript sdk方法）已经有几年了，我正面临着我正在开发的新应用程序的特殊问题。 p>

我的localhost配置为app 虚拟目录如下： p>

  http：// localhost / myapp / 
  code>  pre> 
 
 在Facebook上，进行以下设置 我的应用程序指向该URL：App域，Facebook登录网站，Facebook上的应用程序（https和http）和移动Web。 p> 
 
 
当我执行登录过程并将redirect_uri指向  http：// localhost / myapp /  code>，它工作正常，cookie已设置，我可以对图形api进行查询。 p> 
 
 
当我出现问题时 尝试使用另一个重定向uri，如 http：// localhost / myapp / user_controller / register  code>（将用户添加到数据库）。 虽然它位于Facebook上配置的应用程序URL中，但SDK会输出错误消息（OAuthException |必须使用活动访问令牌来查询有关当前用户的信息。| Code 2500）。 p> 
 
 
我想出来，要解决这个问题一段时间，我必须去facebook应用页面：apps.facebook.com/myapp。 每次我的access_token过期时我都必须这样做，因为这个应用程序不打算在facebook里面，我认为这不是解决这个问题的最佳方法。 p> 
 
 

 I 希望我们能够找到解决这个问题的好方法，这个问题可以帮助未来的开发人员。 p> 
 
 
我正在使用CodeIgniter（我已经使用了大约一年）和Facebook PHP SDK  （直接从github官方仓库下载）作为CI库。 p> 
 
 
再次感谢。 p>

At no point would you get that error during authentication.

I'm pretty sure that you instead have an error in your code that fails to exchange the code for the access_token on the .../register endpoint, and so you end up using an invalid access_token.
