Facebook Session将js-SDK转移到php-SDK [英] Facebook Session Transfer js-SDK to php-SDK
问题描述
我正在使用PHP SDK 2.1.2，并使用标准的 http：//connect.facebook。 net / en_US / all.js 作为JS SDK。
I am using PHP SDK 2.1.2 and using the standard http://connect.facebook.net/en_US/all.js as the JS SDK.
这是我想要实现的：
1）初始化JS Sdk，使用（email，user_location，user_birthday）调用Fb.UI，方法：'oauth'作为响应，如果用户成功授予权限，可以执行ajax调用服务器然后使用PHP-SDK来调用Graph API并获取所需的数据。 （嗯，你可能会争论通过JS SDK调用graph API，但目前的情况需要我使用PHP SDK）
1) Initialize JS Sdk, Call Fb.UI with (email,user_location,user_birthday), method: 'oauth', in response, if the user successfully gives permission do an ajax call to the server and then use PHP-SDK to do a call to Graph API and get the required data. (Well, you might argue to do a call to graph API via JS SDK but the current scenario requires me to use PHP SDK)
问题
通过ajax调用的文件不会初始化会话，而是取消null，而是从理想的情况下加载该cookie并且有权限的活动会话已经在客户端授予。
The file which is called via ajax does not initialize the session and i get null, instead the facebook sdk should ideally load the cookies and have an active session since the permission is granted on the client side already.
我的代码
主文件
<?php
session_start();
header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');
require 'src/facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'xxxxxxxxxxxxxxxxxxxxxxxx',
'secret' => 'yyyyyyyyyyyyyyyyyyyyyyyy',
'cookie' => true,
));
$session = $facebook->getSession();
$me = null;
// Session based API call.
if ($session) {
try {
$uid = $facebook->getUser();
$me = $facebook->api('/me');
print_r($me);
} catch (FacebookApiException $e) {
error_log($e);
}
}

return;
},

}
});
}
});
}

通过AJAX
<?php
session_start();
header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');
require 'src/facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'xxxxxxxxxxxxxxxx',
'secret' => 'yyyyyyyyyyyyyyyyyyyyyyyyyyyy',
'cookie' => true,
));
$session = $facebook->getSession();
$me = null;
// Session based API call.
if ($session) {
try {
$uid = $facebook->getUser();
$me = $facebook->api('/me');
print_r($me);
} catch (FacebookApiException $e) {
error_log($e);
}
}
echo "hello";
?>
如果您在上述示例中看到，我应该在alert框中取得整个/ me对象我刚刚得到你好。我不知道为什么这不工作？我缺少什么？
If you see in the above example, i should get the whole /me object in the alert box instead i just get "hello". I don't know why this isn't working? What am i missing?
场景： -
如果我在页面重新加载（top.location.href）后，授予我获得所需的对象，但我们正在尝试避免重新加载此机制。我也试图设置所需的P3P头，因为我以为可能会有一些cookie问题，但仍然无法加载。
Scenario:- If i do a page reload (top.location.href) after permissions are granted i get the desired objects but we are trying to avoid a reload with this mechanism. I have also tried to set the desired P3P headers because i thought there might be some cookie issue but it still fails to load.
此外，我已经尝试过这个PHP SDK 2.1.1，2.1.2，3.0.1，我听说过较新的PHP-SDK尚不兼容JS SdK，是否真的？
Also, i have tried this with PHP SDK 2.1.1, 2.1.2, 3.0.1, i have heard somewhere that the newer PHP-SDKs are not yet compatible with JS SdK, is it true?
谢谢
推荐答案
您无法使用AJAX调用设置Cookie：在域B上设置第三方Cookie域A要求域B上的页面采取域A上的页面，您的ajax调用不在。
You can't set the cookie using an AJAX call: setting a third-party cookie on domain B by domain A requires that a page on domain B be in the act of fetching a page on domain A, which your ajax call is not doing.
我建议尝试使用您从响应oauth对话框（ permObj-> access_token 获取访问令牌的cookie，除非我错了，我可以）并发布作为AJAX调用的请求参数。然后，您可以使用令牌值调用 $ facebook-> setAccessToken 方法，您应该全部设置。
I'd suggest that instead of trying to use the cookie you fetch the access token from the response to the oauth dialog (permObj->access_token unless I'm wrong, and I could be) and post that as a request parameter with your AJAX call. You can then call the $facebook->setAccessToken method with the token value and you should be all set.
