修正 FB 元标签
经过测试,我发现我错了图像或网址的元标记。更正我网页上的信息后,FB似乎仍然反映旧信息。我可以做些什么来纠正这个问题吗?或者 FB 是否需要一定的时间才能生效?如果需要,需要多长时间?

Facebook share url thumbnail problem
I discovered, after testing, that I had the wrong meta tags for image or url. After correcting the information on my webpage, FB still seems to reflect the old information. Is there something I can do to correct this? Or does FB just take a certain length of time to kick in and if so, how long?

更改标签应该足够了,但是有些标签不允许更改超过某些限制(请检查此处:https://developers.facebook.com/docs/opengraph/“编辑元标签”)。您可以使用 linter 工具检查您的标签是否正确,或者查看它们是否错误 - 为什么它们是错误的:

Changing the tags should be enough, but there are some tags that aren't allowed to change past certain limits (check here: https://developers.facebook.com/docs/opengraph/ under "Editing Meta Tags"). You can use the linter tool to check that your tags are correct, or see, if they are wrong - why they are wrong:
