使用 facebook graph API 时出现无效参数错误

Question

我传递“https://www.cnbc.com/2019/01/13/saudi-energy-minister-on-work-with-oil- Producers-to-balance-market.html”作为网址通过以下链接到 facebook 共享调试器：

Facebook 共享调试器

我们可以看到facebook抓取的所有结果。如果我们向下滚动并查看 URL 部分下列出的条目，我们会看到一个名为 Scrape API 的条目。如果我们单击它，它将打开图形 api 资源管理器，并自动填充字段。

POST/v3.2/?scrape=true&id=https://www.cnbc.com/2019/01/13/saudi-energy-minister-on-work-with-oil-producers-to-balance-market.html

之前可以用，但是突然就不行了。我得到的错误如下所示：

{
  "error": {
    "message": "Invalid parameter",
    "type": "OAuthException",
    "code": 100,
    "error_subcode": 1611008,
    "is_transient": false,
    "error_user_title": "Object Missing a Required Value",
    "error_user_msg": "Object at URL 'https://www.cnbc.com/2019/01/13/saudi-energy-minister-on-work-with-oil-producers-to-balance-market.html' of type 'article' is invalid because a required property 'al:ios:url' of type 'appsite' was not provided.",
    "fbtrace_id": "Gb0BSdJyfGb"
  }
}

我在这里想要实现的是获取 facebook 从提供给调试器的 url 中抓取的数据。

编辑1：

如果您使用以下 url 作为测试并按照上述方式执行 post 请求。成功了，结果如下：

测试网址：

https://www.bloomberg.com/news/articles/2019-01-13/asian-stocks-to-start-mixed-with-earnings-in-focus-markets-wrap?srnd=premium

结果：

{
  "url": "https://www.bloomberg.com/news/articles/2019-01-13/asian-stocks-to-start-mixed-with-earnings-in-focus-markets-wrap",
  "type": "article",
  "title": "Stocks Fall, Bonds Rise as China and Banks Weigh: Markets Wrap",
  "image": [

    }
  ],
  "description": "U.S. stocks declined and Treasuries rose as weak Chinese trade data and troubling signals in bank earnings weighed on investor confidence. The dollar edged lower.",
  "site_name": "Bloomberg.com",
  "updated_time": "2019-01-14T14:38:37+0000",
  "id": "2214485868588392"
}

有人可以解释为什么其他网址在调试器中工作但无法工作吗？
