Facebook PHP SDK getSession（）无法获取会话。 Cookie问题？ [英] Facebook PHP SDK getSession() fails to get session. Cookie problem?

问题描述

背景：

• 使用Facebook PHP SDK v 2.1.2


• cookieSupport = true


• Facebook上的应用程式已启用Canvas的OAuth 2.0


• Facebook连线/登入逻辑是透过单独的子网域（secure.mysite.com）


• 开发网站为dev.mysite.com:PORT_NUM

• 我可以使用Facebook Connect成功登录


• 在通过Facebook对话框授权后，重定向到fbconnect.php，它实例化Facebook类并调用$ facebook-> getSession（）


• 这返回一个有效的Facebook会话，然后继续我们的post-signin逻辑


• 然后我们重定向到已登录的主页
。

不起作用

• 之后的任何时间，$ facebook-> getSession（）返回NULL。无论是什么。


• 根据文档，Facebook应根据cookie重新生成有效的会话，只要它有效。持续时间设置为默认值1小时，但是在Cookie设置失败后30秒内完成调用。

想知道fbs_ cookie中是否有某些东西阻止了登录后会话的再生。与安全子域相关的东西或者我们在开发者网站上使用的端口号？

有很多人在Facebook会话中遇到类似的问题看到，但是我遇到的建议似乎没有解决fbs_ cookie，域，端口等的内容。我理解这样的事情与cookie的关系相对较轻，但我想至少检查他们作为非问题，所以我可以看别处。

欣赏任何分析。

解决方案

新的Facebook PHP SDK（v3）问题消失了

Background:

• Using Facebook PHP SDK v 2.1.2
• cookieSupport = true
• App on Facebook has OAuth 2.0 for Canvas enabled
• Facebook Connect / sign in logic happens over https on a separate subdomain (secure.mysite.com)
• Dev sites are dev.mysite.com:PORT_NUM

What works

• I can sign in successfully using Facebook Connect
• After authorizing via Facebook dialog, we sign the user in and then redirect to fbconnect.php which instantiates the Facebook class and calls $facebook->getSession()
• This returns a valid Facebook session and we proceed with our post-signIn logic
• We then redirect to the signed in home page

What doesn't work

• Any time after that, the $facebook->getSession() returns NULL. No matter what.
• According to the docs, Facebook should regenerate a valid session based on the cookie as long as it's valid. The duration is set to the default of 1 hour, but calls done even 30 seconds after the cookie is set fail.

I'm wondering if there's something in the fbs_ cookie that's preventing the regeneration of a session post sign-in. Something related to the secure subdomain or possibly the port numbers we use on our dev sites?

There are a lot of people having similar problems with Facebook sessions from what I've seen, but the suggestions I've come across don't seem to address the content of the fbs_ cookie, domains, ports etc. My understanding of how such things relate to cookies is relatively light, but I'd like to at least check them off as non-issues so I can look elsewhere.

Appreciate any insights.
