Facebook Open Graph API - og：元标记被忽略 [英] Facebook Open Graph API - og:metatags being ignored
问题描述
我正在排除页面标题和图像未被包含在Facebook上的问题。打了OG调试器后，看起来没有一个 og：元标签正在被Facebook访问：
I'm troubleshooting an issue where the page title and image aren't being included on facebook likes. Having hit the OG debugger, it looks like none of the og:metatags are being accessed by facebook:
< a href =https://developers.facebook.com/tools/debug/og/object?q=http://transactivstaging.cloudapp.net:8080/Pages/ProductSummary.aspx?OrganizationProductID=617c54a0-189a-48af- 9b5e-002148210208& StoreID = a1d6bc99-9a6a-4e46-bdb4-790be4e59bd4& ProductID = d6748a89-41f4-48aa-a1c1-5c28f87cc47f& FBUserId = 100002152993326& PageName = MHMTest& PageID = 236549899706529& CurrentPage = 0rel =noreferrer>这是一个调试器的链接 - 这是说它推断出 og：url 和 og：title 属性存在于页面上。
Here's a link to the debugger — it's saying it is inferring the og:url and og:title properties which are present on the page.
作为测试的问题，我从开发人员文档中的示例中直接复制了元标记和HTML模式，我仍然得到相同的警告。
As a matter of testing, I copied the metatags and HTML schema straight from the example on the developer docs and I still get the same warnings.
以下是生成的标签的HTML和开头：
Here's the HTML and start of the head tag as generated:

有什么想法吗？
推荐答案
Facebook读取您可以在此输入您的网址的所有属性：
https://developers.facebook.com/tools/debug
Facebook reads all properties you can enter your url here: https://developers.facebook.com/tools/debug
Facebook将阅读您指定的属性，但有时只有当所有4被指定（而不是空）时才会使用它们，而不仅仅是最后3个。
Facebook will read the properties you specified, but sometimes will use them only when all 4 are specfied (and not empty), not only the last 3.
<meta property="og:url" content="YOUR_URL" />
<meta property="og:title" content="YOUR_TITLE" />
<meta property="og:description" content="YOUR_DESCRIPTION" />
<meta property="og:image" content="YOUR_IMAGE" />
