问题
I use to implement Facebook's OpenGRaph protocol on my pages (wordpress) based on All In One SEO plugin.
With each page:
<meta property="og:type" content="article">
<meta property="og:title" content="my_title">
<meta property="og:url" content="http://my_site.jp">
<meta property="og:description" content="my_content">
<meta property="article:published_time" content="my_published_time">
<meta property="article:modified_time" content="my_modified_time">
<meta property="og:site_name" content="my_site_name">
<meta property="og:image" content="http://my_site.jp/wp-content/uploads/2017/05/my_image.png">
<meta property="og:image:width" content="600">
<meta property="og:image:height" content="315">
<meta property="og:locale" content="my_cocale">
But i get these error when checking with Facebook developer debug:
URL returned a bad HTTP response code.
Inferred Property
The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.
I have ref from: Facebook Open Graph Error - Inferred Property
But I don't have any solution. Have your solution for this problem?
回答1:
Since your initial link's image issue is now fixed, it's difficult to say what was wrong with it, especially since the snippet you provided seems fine. With the latter link you provided, though, I'm getting this error:
The 'og:description' property should be explicitly provided, even if a value can be inferred from other tags.
This is because there isn't an explicitly og:description tag available on the page.
Someone unrelated: I'm noticing duplicate twitter:card and related tags. This shouldn't cause Open Graph to not work, but should be resolved.
My hunch is that you're using multiple plugins that might be providing the same thing, causing clashes and unexpected behavior. This is why I tend to stay away from "provide it all" plugins, and instead use plugins that do one thing and one thing well. In your case, this might mean using a simpler, more predictable plugin like Complete Open Graph:
