Open Graph SMS rich messages on Android and iOS

由 点点圈 提交于 2020-01-02 05:23:29
问题 I am trying to leverage the rich text messages with open graph meta tags. So I have included my meta tags in my website head and it passes all of the Facebook debug and iOS API validation tool.

Dynamic Image for Facebook Opengraph og:image meta tag

由 北慕城南 提交于 2020-01-01 06:08:06
问题 I am trying to share an image from my website on facebook. The image can be dynamic, but other meta will remain the same. Is there a way I can have dynamic data in OG:IMAGE tag, or will I have to go with the other option of FB Post APIs. 回答1: Yes and no. Facebook scrapes your site once, and cached the metadata that it finds, unless you specifically go here and force the scraper to crawl your site again. The cache does generally expire (perhaps after 1-2 days?), so when requested again outside

由 混江龙づ霸主 提交于 2020-01-01 04:40:08

Facebook open graph meta tags maximum content length

由 自古美人都是妖i 提交于 2019-12-31 10:19:14
问题 Does anyone know the maximum valid length for each of Facebook's open graph meta tags? The description of the meta tags on http://ogp.me/ does not list maximum lengths, only general descriptions such as "A one to two sentence description of your object" for the og:description meta tag. From what I understand, there is no maximum content length for meta tags in general, just recommendations to keep them under certain lengths for SEO reasons. I'd be curious to know if there is a hard limit and

Facebook Open Graph Single Page Apps

由 倾然丶 夕夏残阳落幕 提交于 2019-12-30 07:12:30
问题 I have built a single page application using backbone js.

Facebook Debugger lint tool gets HTTP 206 - doesn't detect Open Graph meta tags (others tools do)

由 北战南征 提交于 2019-12-29 01:38:17
问题 I believe my site has the correct markup for Facebook & Open Graph meta tags. But checking Facebook's linter shows that none of the tags are being detected. You can see for yourself here: http://developers.facebook.com/tools/debug/og/object?q=goodloesolitaire.com When I use a different site, the tags are found: http://www.opengraph.in/?url=goodloesolitaire.com&format=html I went through the similar questions and none of those check out. Any ideas on why Facebook's debugger might see nothing?

How to do Facebook Open Graph friendly meta tags with client-side template engines like AngularJS, Mustache, Handlebars

由 依然范特西╮ 提交于 2019-12-28 15:58:22
问题 According to my testing, Facebook's crawlers do not render client-side templates like a browser. I want to avoid a webserver and building HTML files for Open Graph objects at all costs. I want to generate the meta tags on the fly via the URL, but it seems Facebook cannot do this. Can someone from Facebook please confirm? I asked the head of Open Graph at #mobiledevcon and she said that Facebook can render stuff like {{value}} My meta tags are as follows, and they render fine in every browser.
