根据document，Open Graph API支持在不指定 og:title 属性的情况下创建对象 . 我'm using the Object API, and since the objects I' m在我的请求中定义了don 't have meaningful titles, I presumed that I could do the same by just not including a ' title'字段 .

我发送的请求（通过Graph API Explorer）与此相同：

POST https://graph.facebook.com/me/objects/namespace:foo
     object={
       "image": "http://cdn.example.com/images/bar/l",
       "url": "http://example.com/photos/baz?image=bar",
       "description": "Image caption",
       "site_name": "Example"
     }

除此之外，我一直得到的回应是：

{
  "error": {
    "message": "(#100) Object Missing a Required Value: Object at URL 'http://example.com/photos/baz?image=bar' of type 'namespace:foo' is invalid because a required property 'og:title' of type 'string' was not provided.", 
    "type": "OAuthException", 
    "code": 100
  }
}

那么，根本不可能通过Object API创建没有 Headers 的对象吗？这仅适用于自托管对象吗？
