使用 Facebook 的 PHP SDK v4 创建用户拥有的 Open Graph 对象

Question

有没有人尝试使用v4.0.* of their PHP SDK 创建user-owned Facebook Open Graph objects？我无法在线找到最新的 Open Graph PHP 请求的任何工作示例。

目前，我的请求如下所示：

$graphObject = (
    new FacebookRequest(
        $this->facebookSession, 
        'POST', 
        "/me/objects/{$objectType}", [
            'title' => $title,
            'image' => $image,
            'url' => $url,
            'description' => $description,
            'site_name' => $this->siteName
        ]
    )
)->execute()->getGraphObject();

这会抛出一个FacebookAuthorizationException:

(#100) 参数对象为必填项

我也试过这个请求：

$graphObject = (
    new FacebookRequest(
        $this->facebookSession, 
        'POST', 
        "/me/objects/{$objectType}", [
            'title' => $title,
            'image' => $image,
            'url' => $url,
            'description' => $description,
            'type' => $objectType,
            'site_name' => $this->siteName
        ]
    )
)->execute()->getGraphObject();

这会抛出一个FacebookAuthorizationException：

不能在路径和查询参数中都指定类型

最后，我尝试了这个请求：

$graphObject = (
    new FacebookRequest(
        $this->facebookSession, 
        'POST', 
        "/me/objects/", [
            'title' => $title,
            'image' => $image,
            'url' => $url,
            'description' => $description,
            'type' => $objectType,
            'site_name' => $this->siteName
        ]
    )
)->execute()->getGraphObject();

这会引发FacebookAuthorizationException：

(#100) 参数对象为必填项

在我上面链接的用于创建 Open Graph 对象的文档中，我看到了正确的 cURL 请求是什么，我只是有点迷失了如何使用 PHP SDK 实际发出这个请求。提前感谢您的帮助！

我相信您需要像这样对object 参数进行 JSON 编码：

$graphObject = (
    new FacebookRequest(
        $this->facebookSession, 
        'POST', 
        "/me/objects/{$objectType}",
        [
          'object' => json_encode([
            'title' => $title,
            'image' => $image,
            'url' => $url,
            'description' => $description,
            'site_name' => $this->siteName
          ])
        ]
    )
)->execute()->getGraphObject();
