我正在尝试通过 opengraph 创建自定义对象并将其发布到 facebook 时间线。已按照开发人员 Facebook 上的教程进行操作。
我遇到了几个错误 - 第一个是如果我尝试以教程中建议的方式发布对象（使用 js SDK），我会收到以下错误消息：
OG：(#3502) URL http://markaprice.co.uk/2012dev/fb-ojects/dow.html上的对象具有 og:type 的“网站”。属性 'travel_goal' 需要 og:type 'mp-object-ns:travel_goal' 的对象
（类型在元中正确设置）
做了一些研究，这似乎是由于同时的 http 请求，我读到的一个建议是你可以强制 openGraph 抓取页面，然后执行你的帖子以避免这个问题 -
我已经尝试过了，除了我现在遇到了一个不同的错误：
scrape: (#803) 您请求的某些别名不存在：id=http:
我在以下位置设置了一个非常粗略的工作示例：

请有人告诉我我做错了什么，因为我不确定接下来要尝试什么 - 非常感谢。
我的代码在这里：
