mod-rewrite和Facebook $ _ GET变量 [英] Mod Rewrite and Facebook $_GET variables

问题描述

在写我的登录系统，我授权与Facebook的用户，当遇到一个小问题...

While writing my login system, I came across a little issue when authorizing an user with Facebook...

在有人点击登录与Facebook按钮，体征/授权我的应用程序，Facebook的重定向回我的网站，推出了一系列的 $ _ GET 的变量，正常。唯一的问题是我想看看如果这些变量之一是为了检查Facebook登录的状态设置。

After someone clicks the 'Login with Facebook' button and signs in/authorizes my app, Facebook redirects back to my site, with a series of $_GET variables, as normal. The only issue is I'd like to check if one of those variables are set in order to check the status of the Facebook login.

当我尝试拉 $ _ GET 变种，它说，它不存在。这个问题是我使用mod_rewrite清理我的网址的apparence：

When I try pulling the $_GET var, it 'says' it doesn't exist. The issue is with my using mod_rewrite to clean up the apparence of my url:

#RewriteRule ^([A-Za-z0-9]+)/?$ ?a=b&content=$1 [L]
#RewriteRule ^([A-Za-z0-9]+)/([A-Za-z0-9]+)/?$ ?a=b&content=$1&page=$2 [L]

这将打开：
www.mysite.com?content=login&page=2 进入
www.mysite.com /登录/ 2

所以，我的网址 www.mysite.com/content?state = [...]放; code = [...]放大器; ...等必须混淆Facebook的分配变量，与被重写 $ _ GET 瓦尔。

So my url of www.mysite.com/content?state=[...]&code=[...]&...etc must be confusing the variables Facebook assigns, with the to be rewritten $_GET vars.

同样的事情发生在一个url与的内容和页面设置。例如： www.mysite.com/content/page?state = ......

Same thing happens with a url with both the content and page set. eg: www.mysite.com/content/page?state=......

什么是解决这个的最好方法？我知道我能找到另一种方式来显示一个确认的Facebook登录，但是这仍将是一个问题，在今后的其他情况下，我敢肯定。

What would be the best way of solving this? I know I could find another way to show a confirmed Facebook login, but this will continue to be an issue for other situations in the future, I'm sure.

在此先感谢。

推荐答案

尝试使用 [L，QSA] ，而不是仅仅 [L] 。

Try using [L,QSA] instead of just [L].
