Facebook Open Graph API - og:元标签被忽略

发布于 2024-12-13 16:32:33 字数 1811 浏览 0 评论 0 原文

我正在解决页面标题和图像未包含在 Facebook 点赞中的问题。点击 OG 调试器后，facebook 似乎没有访问任何 og: 元标签：

这是调试器的链接 - 它表示它正在推断 og:url 和 og:title 属性，这些属性存在于页。

作为测试，我直接从开发人员文档的示例中复制了元标记和 HTML 架构，但仍然收到相同的警告。

这是生成的 HTML 和 head 标签的开头：

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<title>123-ABC Butterfly Fun Carpet 3'10" x 5'5" Rectangle</title>
<meta name="description" content="Transactiv Products" />
<meta name="title" content="Transactiv" />
<meta property="fb:app_id" content="289501899130" />
<meta property="og:site_name" content="Transactiv InRecv" />
<meta property="og:url" content="http://localhost:2609/Pages/ProductSummary.aspx?OrganizationProductID=617c54a0-189a-48af-9b5e-002148210208&StoreID=a1d6bc99-9a6a-4e46-bdb4-790be4e59bd4&ProductID=d6748a89-41f4-48aa-a1c1-5c28f87cc47f&PageName=MHMTest&PageID=236549899706529" />
<meta property="og:title" content="123-ABC Butterfly Fun Carpet 3'10" x 5'5" Rectangle" />
<meta property="og:type" content="website" />
<meta property="og:description" content="" />
<meta property="og:image" content="http://transactivazureprod.blob.core.windows.net/pictureblob/831a4d4a-dbe3-44f5-9ff8-12286cdc33f5" />

对此有什么想法吗？

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:

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.

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.

Here's the HTML and start of the head tag as generated:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml">
<head>
<title>123-ABC Butterfly Fun Carpet 3'10" x 5'5" Rectangle</title>
<meta name="description" content="Transactiv Products" />
<meta name="title" content="Transactiv" />
<meta property="fb:app_id" content="289501899130" />
<meta property="og:site_name" content="Transactiv InRecv" />
<meta property="og:url" content="http://localhost:2609/Pages/ProductSummary.aspx?OrganizationProductID=617c54a0-189a-48af-9b5e-002148210208&StoreID=a1d6bc99-9a6a-4e46-bdb4-790be4e59bd4&ProductID=d6748a89-41f4-48aa-a1c1-5c28f87cc47f&PageName=MHMTest&PageID=236549899706529" />
<meta property="og:title" content="123-ABC Butterfly Fun Carpet 3'10" x 5'5" Rectangle" />
<meta property="og:type" content="website" />
<meta property="og:description" content="" />
<meta property="og:image" content="http://transactivazureprod.blob.core.windows.net/pictureblob/831a4d4a-dbe3-44f5-9ff8-12286cdc33f5" />

Any ideas on this?

Facebook 会读取您可以在此处输入网址的所有属性：
https://developers.facebook.com/tools/debug

Facebook 将读取您指定的属性，但有时仅当指定所有 4 个（且不为空）时才会使用它们，而不仅仅是最后 3 个。

<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" />

Facebook reads all properties you can enter your url here:
https://developers.facebook.com/tools/debug

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" />

明显的缺陷。你没有直接结束标题。你里面有 " 。

我建议在 echo'ing 之前执行 str_replace('"', "''", $str) 。

即

编辑：

您还可以考虑执行 htmlentities($str, ENT_QUOTES)，如 @TwoWholeWorms 所建议，

Facebook 的抓取工具在尝试访问您的网站。

您可以通过调试页面底部的“准确查看我们的抓取工具所看到的内容”链接来访问 Facebook 抓取工具的页面视图。

ShoppingCart.GetShoppingCartItems.Failed If this Error persists, you can contact our support and provide the following Error Id as a reference

Facebook's scraper is seeing an error page when it tries to visit your site.

You can access the Facebook scraper's view of your pages through the link 'See exactly what our scraper sees' at the bottom of the debug page.

Also it doesn't just seem to be a scraper related problem as I'm also seeing the same message when I visit the link: 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=0

我猜想，以及 Robin Castlin" > （您也可以将其转义为 "），您的 og:url 包含未转义的 & 符号，

如果替换 & 是否有效。代码> 与& 位于 og:url 字段中？

因此您需要替换

<meta property="og:title"
  content="123-ABC Butterfly Fun Carpet 3'10" x 5'5" Rectangle" />
<meta property="og:url"
  content="http://localhost:2609/Pages/ProductSummary.aspx?
  OrganizationProductID= ... &StoreID= ..." />

<meta property="og:title"
   content="123-ABC Butterfly Fun Carpet 3'10" x 5'5" Rectangle" />

<meta property="og:url"
  content="http://localhost:2609/Pages/ProductSummary.aspx?
  OrganizationProductID= ... &StoreID= ..." />

以确保元数据全部包含有效的 HTML。

I would guess that, as well as the " in the title values mentioned by Robin Castlin (which you could also escape as "), that your og:url contains unescaped ampersands.

Does it work if you replace & with & in that og:url field?

So you'd replace

<meta property="og:title"
  content="123-ABC Butterfly Fun Carpet 3'10" x 5'5" Rectangle" />
<meta property="og:url"
  content="http://localhost:2609/Pages/ProductSummary.aspx?
  OrganizationProductID= ... &StoreID= ..." />

<meta property="og:title"
   content="123-ABC Butterfly Fun Carpet 3'10" x 5'5" Rectangle" />

<meta property="og:url"
  content="http://localhost:2609/Pages/ProductSummary.aspx?
  OrganizationProductID= ... &StoreID= ..." />

to make sure the metadata all contains valid HTML.
