Facebook分享找不到og：image標簽

Question

我試圖弄清楚Facebook共享協議如何獲取其圖像。

示例文章： http : //www.startribune.com/sleepy-eye-quads-celebrate-65th-birthday/302364361/

截至目前（CDT 2015年5月8日1:00 pm），將該URL插入https://developers.facebook.com/tools/debug/og/object/會發出以下警告： og:image was not defined, could not be downloaded or was not big enough. Please define a chosen image using the og:image metatag, and use an image that's at least 200x200px and is accessible from Facebook. Image 'http://stmedia.stimg.co/obed021814.JPG?w=600&h=600' will be used instead. og:image was not defined, could not be downloaded or was not big enough.

但是，在頁面的“基於原始標記”頁面的下方，我們構造了頁面的以下“打開圖屬性”，它清楚地顯示了頁面上og：image標記中的正確圖像。

為什么打開圖會認為og：image未定義，或者在可以找到它的頁面很遠的地方無法訪問它？

標頭中的meta標簽如下：

    <link rel="canonical" href="http://www.startribune.com/sleepy-eye-quads-celebrate-65th-birthday/302364361/" />
    <meta property="og:url" content="http://www.startribune.com/sleepy-eye-quads-celebrate-65th-birthday/302364361/" />
    <meta property="og:title" content="Sleepy Eye quads celebrate 65th birthday" />
    <meta property="og:site_name" content="Star Tribune" />
    <meta name="news_keywords" content="" />
    <meta name="description" content="The Sleepy Eye quads have returned to their childhood home in southern Minnesota to celebrate their 65th birthday." />
    <meta property="og:description" content="The Sleepy Eye quads have returned to their childhood home in southern Minnesota to celebrate their 65th birthday."/>
    <meta property="og:image" content="http://stmedia.startribune.com/images/1430701562_10026501+Quads+Birthday.JPG" />

Answer 1

如@CBroe所述，最好在Facebook調試器中運行與頁面相關的所有鏈接。

至於具體的圖像問題，如果可能的話，我還建議您添加og:image:width和og:image:height元標記，以幫助抓取工具按照此文檔抓取您的圖像。

如果您還有其他頁面遇到相同的問題，那么在嘗試在調試器中運行圖像url本身之前，我將提供上述標簽，以查看是否有幫助。
