如何使用facebook php SDK访问Facebook个人资料图片？ [英] How to access facebook profile picture using facebook php SDK?

问题描述

我正在使用以下代码访问用户个人资料图片。

I am using the following code to access users profile picture.

这是我如何创建请求

<?php 
session_start();

include 'facebook-php-sdk/autoload.php';

use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookSession;

$permissions = array(
  'email',
  'user_location',
  'user_birthday',
  'user_photos',
  'public_profile'
);

/* Set the public and secret keys */
FacebookSession::setDefaultApplication('XXX', 'XXX');

$helper = new FacebookRedirectLoginHelper('http://localhost/oauth/login.php');
$loginUrl = $helper->getLoginUrl($permissions);
// Use the login url on a link or button to redirect to Facebook for authentication

?>
    <a href="<?php echo $loginUrl; ?>">Login using facebook</a>

<?php

？

这是页面用户被重定向到..

<?php 
session_start();
include 'facebook-php-sdk/autoload.php';

use Facebook\FacebookRedirectLoginHelper;
use Facebook\FacebookRequest;
use Facebook\FacebookSession;

FacebookSession::setDefaultApplication('XXXX', 'XXXX');
$helper = new FacebookRedirectLoginHelper('http://localhost/oauth/login.php');
try {

  $session = $helper->getSessionFromRedirect();

} catch(FacebookRequestException $ex) {
// When Facebook returns an error

} catch(\Exception $ex) {
// When validation fails or other local issues

}
if ($session) {
    // Logged in


    // $request = new FacebookRequest($session, 'GET', '/me');
    // $response = $request->execute();
    // $graphObject = $response->getGraphObject();


    // var_dump($graphObject->asArray());

    $request = new FacebookRequest(
      $session,
      'GET',
      '/me/picture'
    );
    $response = $request->execute();
    $graphObject = $response->getGraphObject();

    var_dump($graphObject->asArray());
}

？

我总是得到输出为array（0）{} - >一个空数组。我无法弄明白这个代码有什么问题，我在访问图形查询时遇到了一些访问权限吗？

I am always getting output as "array(0) { }" -> an empty array. I cant figure out whats wrong with this code, did I missed some permission while getting login url or anything wrong with the graph query??

推荐答案

我预计有一些默认行为，但结果是需要额外的选项才能使查询成功。

I expected some default behavior but turns out that extra option is required for the query to be successful.

$request = new FacebookRequest(
          $session,
          'GET',
          '/me/picture',
          array (
                'redirect' => false,
                'type' => 'large'
              )
        );
