问题Facebook PHP SDK登录机制

Question

我对Facebook PHP SDK登录机制有一些（理解）问题。

当我尝试使用我的应用设置中找到的静态access_token登录时，一切正常。

但是：我如何从代码参数解析它，这是由登录回调给出的？或者我在哪里动态获取access_token以便发布内容？

我尝试做的是使用我的用户帐户在Facebook页面上发布内容。

我使用静态令牌的代码是：

$redirected = $_GET('redirected');

if (!empty($redirected) && $redirected === 'true')
{
    $callback = $_GET('callback') . '?code=' . $_GET('code');
    header("Location: {$callback}");
    exit(0);
}


class CFacebookClient
{
    // BEGIN CONFIG settings
    protected $sAppId;
    protected $sSecret;
    protected $bFileUpload = false;
    protected $bAllowSignedRequest = false;
    // END CONFIG settings


    protected $facebook;

    protected $sUid;

    protected $sLoginCallback = 'http://localhost/facebook/test.facebookclient.php?loggedin=true';

    public function retrieveProfile()
    {
        return $this->facebook->api('/me/accounts', 'GET', array('access_token' => $this->sAuthCode));
    }
}

test.facebookclient.php文件：

$sAppId = 'xxxx';
$sSecret = 'xxxx';

$sLoggedin = $_GET('loggedin');
$fb = new CFacebookClient($sAppId, $sSecret);
$fb->init();

if ($sLoggedin === 'true')
{
    $fb->setAuthCode('ddddd');
    //$fb->setAuthCode($_GET('code'));
    var_dump($fb->retrieveProfile());
    exit(0);
}

if (!$fb->loginPages())
{
    header('Location: ' . $fb->getLoginUrl());
    exit(0);
}
else
{
    var_dump($fb->retrieveProfile());
    exit(0);
}
exit(0);

编辑：

解决方法是在/ me / accounts从方法retrieveProfile（）

中隐藏api调用之后删除所有内容
