更新2：
好的,通过改变它“有点”工作：
$loginUrl = $facebook->getLoginUrl(array(
'canvas' => 1,
'fbconnect' => 0,
'req_perms' => 'publish_stream',
'next' => 'http://'.$_SERVER['SERVER_NAME'].'/success.php',
'cancel_url' => 'http://'.$_SERVER['SERVER_NAME'].'/cancel.php'
));
对此：
$loginUrl = $facebook->getLoginUrl(array(
'canvas' => 1,
'fbconnect' => 0,
'req_perms' => 'publish_stream',
'next' => 'http://'.$_SERVER['SERVER_NAME'].'/success.php',
'cancel_url' => 'http://'.$_SERVER['SERVER_NAME'].'/cancel.php'
));
header('Location: '.$loginUrl);
即我添加了标题(‘Location：’.$loginUrl);.
但页面表现得很奇怪.我必须导航到页面,登录,然后刷新页面,再次登录,然后它会要求我允许发布到页面,并最终发布到页面.
为什么我要登录两次？
更新1：
我现在有以下脚本似乎不起作用.在这种状态下,我只是想张贴到自己的墙上,但最终也想发布到朋友的墙上：

我收到以下错误：
[Wed Apr 27 22:28:16 2011] [error] [client <ip address removed for security reasons>] OAuthException: (#200) The user hasn't authorized the application to perform this action, referer: http://<ip address removed for security reasons>/index.php
原始问卷：
我有以下工作脚本,允许有人使用他们的Facebook详细信息登录我的页面,然后我可以捕获他们的access_token,所以我可以使用它与图形api：

用户登录后,我了解到我可以通过以下方式获取他们的朋友列表：
https://graph.facebook.com/me/friends?access_token=...
我无法弄清楚如何使用扩展权限,所以我的应用程序可以发布给用户朋友的Facebook墙.
显然我应该使用扩展的权限加上以下内容：
curl -F 'access_token=...' \
-F 'message=Hello, Arjun. I like this new API.' \
https://graph.facebook.com/arjun/feed
我不明白我应该如何从PHP做到这一点.
解决方法:
更新：
好吧,我自己无法真正测试它,所以只需要一些建议就可以尝试.将$loginUrl更改为：
$loginUrl = $facebook->getLoginUrl(array(
'req_perms' => 'publish_stream',
'next' => 'http://'.$_SERVER['SERVER_NAME'].'/success.php',
'cancel_url' => 'http://'.$_SERVER['SERVER_NAME'].'/cancel.php'
));
在整个上下文中,文件的顶部应如下所示：
require 'facebook.php';
$facebook = new Facebook(array(
'appId' => '<appId removed for security reasons>',
'secret' => '<secret removed for security reasons>',
'cookie' => true,
));
$session = $facebook->getSession();
$me = null;
if ($session)
{
try
{
$uid = $facebook->getUser();
$me = $facebook->api('/me');
$post = $facebook->api("/me/feed", "POST", array('message' => 'Hello! I\'m using the FB Graph API!'));
}
catch (FacebookApiException $e)
{
error_log($e);
}
}
else
{
$loginUrl = $facebook->getLoginUrl(array(
'req_perms' => 'publish_stream',
'next' => 'http://' . $_SERVER['SERVER_NAME'] . '/success.php',
'cancel_url' => 'http://' . $_SERVER['SERVER_NAME'] . '/cancel.php'
));
header('Location: ' . $loginUrl);
}
那么,首先检查您是否有会话,因此您需要像示例中那样配置Facebook SDK：
$facebook = new Facebook(array(
'appId' => 'app id goes here',
'secret' => 'secret id goes here',
'cookie' => true,
));
然后,您可以检查用户是否已登录并且您的应用已获得授权：
if ($facebook->getSession() == null) {
// not logged in or not authorized
}
在if子句中,您必须重定向到正确的login-url以获得所需的所有权限：
$loginUrl = $facebook->getLoginUrl(array(
'canvas' => 1,
'fbconnect' => 0,
'req_perms' => 'publish_stream',
'next' => // url where to go when you were authorized
'cancel_url' => // url to go to when user cancelled
));
header('Location: '.$loginUrl);
获得权限后,您可以使用在文档中提到的发布
$facebook->api(/* url */, array(/* additional parameters go here */));
