Facebook Sharer看不到OG：IMAGE标签在第一次检查 [英] Facebook Sharer Can't See OG:IMAGE Tag At First Check

问题描述

我正在尝试通过Facebook分享此网址（由于facebook缓存，用任意随机字符串更改RANDOM_STRING）：

I am trying to share this url via facebook(change RANDOM_STRING with any random string because of facebook cache):

http://www.ikposta.com/blog/goster/72/test_RANDOM_STRING

首先尝试Facebook将决定图片是有一个男人。刷新Facebook页面，然后再次尝试分享相同的网址，此时图片将被更改，您将看到正确图像的键盘图像。

at first try facebook will decide picture which is there is a men. Refresh facebook page and try again share with same url at this time picture will be changed and you will see keyboard image which is correct image.

og ：image 标签总是正确的，为什么会发生这种情况？

og:image tag is always correct why this is happening ?

如何防止？

推荐答案

Facebook对象调试器，以确保您的OG图像标记正确被Facebook接收。这也将强制重新缓存图像。

Run your URL through the Facebook Object Debugger to make sure that your OG image tag is correctly being picked up by Facebook. This will also force a re-cache of the image.

我快速运行，出现了几个错误。主要缺少URL和标题OG标签。你会想要避免循环重定向。参见这里： Debugged

I ran it through quickly and there were a couple errors that came up. Primarily missing URL and title OG tags. You'll want to have these to avoid circular redirects. See here: Debugged

我将个人删除那个缓存中的一切。这是Facebook的混乱，因为它看起来像一个目录。如果有的话，请使用查询字符串。

I would personally remove that cache bust all together. It's confusing Facebook because it looks like a directory. If anything, use a query string.
