Question

我需要下载（通过php：curl，file_get_contents ...）将完整图片发布到网站文件夹。

我可以获得帖子项目数据，甚至是full_picture网址，但是当我想通过wget或curl下载时，服务器会以403响应。

如果我尝试通过浏览器下载该网址，没问题，我可以看到它。

但如果我尝试使用curl或wget，我会收到401响应

wget https://scontent.xx.fbcdn.net/hvthumb-xta1/v/t15.0-10/s720x720/12525704_987920591279679_1409522552_n.jpg?oh=33b2b223cc3e6c2ddd1a94f098c44457&oe=5748C6D2

我也试过将访问令牌附加到路径：

...&access_token=XXXXXXXX

这是json帖子项目：

                                )

                )

        )

我以这种方式从Facebook页面获取帖子信息。

启动Facebook课程：

$this->facebook = new Facebook([
  'app_id' => $app_id,
  'app_secret' => $app_secret,
  'default_graph_version' => 'v2.5',
  //'default_access_token' => '{access-token}', // optional
]);

获取发布数据：

...
$fields = array(
  'id',
  'application',
  'call_to_action',
  'caption',
  'created_time',
  'description',
  'from',
  'icon',
  'is_hidden',
  'is_published',
  'link',
  'message',
  'message_tags',
  'name',
  'object_id',
  'picture',
  'full_picture',
  'place',
  'privacy',
  'properties',
  'source',
  'status_type',
  'story',
  'story_tags',
  'targeting',
  'to',
  'type',
  'updated_time',
  'with_tags',
  'actions',
  // 'tags',
  // 'object_attachment',
  'feed_targeting',
  'attachments',
);
$data = $this->facebook->get($id . '?fields=' . implode(',', $fields));
$item = json_decode($data->getBody());
$object (object) $item;

Ty设置UA就像@CBroe提到的那样：

wget -U Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36 {your-url}

您可以考虑使用cURL作为替代方案： Saving image from PHP URL

Facebook php sdk v5 - 下载feed的完整图片
