facebook上的Open Graph Protocol vs sharing链接？

Question

当我使用图形协议让facebook获取我们的链接时，我有一个问题，如下所示。(我的网站是越南语)

Fisrt:我在susongmoi.net/facebook.html上做了一个测试(它工作得很好)

第二:我将这个(标签)应用到其他页面，比如url：http://sucsongmoi.net/48/tam-kieu-ca-si-thu-minh-6882s.html，但是它不再起作用了。我觉得很奇怪。我在https://developers.facebook.com/tools/debug上做了一个测试，但我似乎找不到问题所在。

提前感谢

代码：

这是第二个链接的meta：

<title>Tắm kiểu ca sĩ Thu Minh - SSM</title>
<meta property="og:title" content="Tắm kiểu ca sĩ Thu Minh - SSM" />
<meta property="og:type" content="article" />
<meta property="og:url" content="sucsongmoi.net/48/tam-kieu-ca-si-thu-minh-6882s.html"; />

<meta property="og:image" content="sucsongmoi.net/images/logo.png"; />
<meta property="og:site_name" content="SSM" />
<meta property="og:description" content="des" />

一个小问题，为什么你的属性后面有分号？

<meta property="og:url" content="sucsongmoi.net/facebook.html"; />
<meta property="og:url" content="sucsongmoi.net/48/tam-kieu-ca-si-thu-minh-6882s.html"; />

当我调试你的链接时，FB调试器说：

Inferred Property:  The og:url property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property:  The og:title property should be explicitly provided, even if a value can be inferred from other tags.

这意味着您没有在页面上放置meta标签，请再次检查
