Blogger：Facebook分享 - 图片问题

Question

当我尝试在Facebook上分享我的博主的任何内容时，或者如果我只是复制链接并粘贴那里会发生这样的事情（请参阅应该有图像的空白方块）：

我试着看看Facebook developer tool，并说：

Warnings That Should Be Fixed
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.
Inferred Property   The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.
Share App ID Missing    The 'fb:app_id' property should be explicitly provided, Specify the app ID so that stories shared to Facebook will be properly attributed to the app. Alternatively, app_id can be set in url when open the share dialog.

我试图遵循我找到的一些解决方案：

1）编辑HTML并在</head>标记上方粘贴以下代码。

<b:if cond='data:blog.postImageThumbnailUrl'>
<meta expr:content='data:blog.postImageThumbnailUrl' property='og:image'/>
<b:else/>
<meta content='http://www.your-blog-logo.jpg' property='og:image'/>
</b:if>

2）搜索<b:includable id='post' var='post'>并在此标记后粘贴以下代码

<meta expr:content='data:blog.pageName' property='og:title'/>
<meta expr:content='data:blog.canonicalUrl' property='og:url'/>
<meta expr:content='data:blog.title' property='og:site_name'/>
<meta content='article' property='og:type'/>
<b:if cond='data:post.firstImageUrl'>
<meta expr:content='data:post.firstImageUrl' property='og:image'/>
<meta content='1200' property='og:image:width'/>
<meta content='630' property='og:image:height'/>
<b:else/>
<b:if cond='data:blog.postImageUrl'>
<meta expr:content='data:blog.postImageUrl' property='og:image'/>
<meta content='1200' property='og:image:width'/>
<meta content='630' property='og:image:height'/>
<b:else/>
<meta content='https://lh3.googleusercontent.com/-9Fy3-ME-5VA/VfhZDh1oQOI/AAAAAAAABFc/SPkLmVpV1aY/s1600/no-thumbanil-available.png' property='og:image'/>
</b:if>
</b:if>
<b:if cond='data:blog.metaDescription'>
<meta expr:content='data:blog.metaDescription' name='og:description'/>
<b:else/>
<meta expr:content='data:post.snippet' name='og:description'/>
</b:if>

这些解决方案都没有解决问题。你能救我吗？
