在Facebook上共享链接. Facebook不获取描述和图像 [英] Share link on facebook. facebook do not fetch to get description and image

问题描述

我正在开发sucsongmoi.net(越南语)，当查看者从他们的墙上共享站点的链接时，某些链接facebook获得描述和图像，而某些链接facebook无法获得描述和图像.

I'm develop sucsongmoi.net (vietnamese language) and when viewer share link of site from their wall some link facebook get description and image, some link facebook could not get description and image.

例如:分享sucsognmoi.net facebook没有得到描述，图片 但是当我分享时:sucsongmoi.net/nau-gi-hom-nay-84.html Facebook可以获取描述和图像.

eg: share sucsognmoi.net facebook do not get description, image but when i share: sucsongmoi.net/nau-gi-hom-nay-84.html facebook could get description and image.

我感到很奇怪，因为我为此实现了相同的代码.

I feel odd because I implement same code for this.

当我通过以下方式分享时:
https://www.facebook.com/sharer/sharer.php?u=http://www.sucsongmoi.net/?a=1
然后就可以了.那是Facebook缓存我的网站吗(nhưgoogle index)?那我该如何更新呢?

when I share through:
https://www.facebook.com/sharer/sharer.php?u=http://www.sucsongmoi.net/?a=1
then it works. Is that facebook cache my site (như google index)? Then how can I update it?

预先感谢

推荐答案

在这里，facebook提供了一个很好的工具来处理这些问题-
认识Facebook的 URL调试器.

关于您的问题，您可以从

Here is a great tool facebook provides us to deal with exactly these issues -
Meet facebook's URL Debugger.

With regard to YOUR problems, you can see from this report that facebook is unable to retrieve the title & url og:tags.... this is possibly due to the non-standard character set that you are using... can you try change the og:title value to something with only regular English letters? Or alternatively placing some Unicode characters instead.
