Facebook打开图形错误 - 推断属性 [英] Facebook Open Graph Error - Inferred Property
问题描述
在每个页面上，我都在头上部分显示了这个：
< html xmlns =http://www.w3.org/1999/xhtmlxmlns：og =http://ogp.me/ ns＃xmlns：fb =http://www.facebook.com/2008/fbml>
然后在头部我有：
< meta property =og：titlecontent =本页标题/>
< meta property =og：typecontent =product/>
< meta property =og：urlcontent =http://www.mywebaddress.com/>
< meta property =og：imagecontent =http：//www.myimage.jpg/>
< meta property =og：site_namecontent =我的网站名称/>
< meta property =fb：adminscontent =10101010101/>
< meta property =og：emailcontent =hello@mywebaddress.com/>
< meta property =og：descriptioncontent =我的产品说明。/>
然后我有一个喜欢按钮，代码如下：
< script>（function（d，s，id）{
var js，fjs = d.getElementsByTagName s）[0];
if（d.getElementById（id））{return;}
js = d.createElement（s）; js.id = id;
js.src = //connect.facebook.net/en_US/all.js#xfbml=1;
fjs.parentNode.insertBefore（js，fjs）;
}（document，'script'，'facebook- jssdk'））;< /脚本>
< div class =fb-likedata-href =http：// thispagesurldata-send =truedata-width =350data-show-faces =false> < / DIV>
对我来说，似乎所有的东西都可以复制到 Facebook开发者页面，但是当我喜欢'，Facebook似乎只是拾起页面标题和一般信息。
我已经尝试使用他们的对象调试器调试页面，我收到以下警告：
推断属性应该显式提供og：url属性，即使可以从其他标记推断值。
推断属性应该显式提供og：title属性，即使可以从其他标记推断值。
推断属性应该显式提供og：image属性，即使可以从其他标记推断值。
推断属性应该显式提供og：locale属性，即使可以从其他标记推断值。
据我所知，我已经按照Facebook的说明来信，但我没有快乐。任何人都可以指出，如果我做错了什么？
提前感谢
Dan
这些标签是http://www.mywebaddress.com吗？
请记住，linter将遵循og：url标签，因为此标签应指向该内容的规范网址，因此，如果您有一个页面，例如'http://mywebaddress.com/article1'与 og：url 标签指向http://mywebaddress.com，Facebook会去那里阅读标签还有。
如果没有，最常见的原因是看到正确的标签没有被linter检测到，因为用户代理检测将不同的内容返回到Facebook的抓取工具您手动检查
时所看到的内容
I'm trying to implement Facebook's OpenGRaph protocol on my product pages.
On each page i have this above the head section:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:og="http://ogp.me/ns#" xmlns:fb="http://www.facebook.com/2008/fbml">
Then within the head section i have:
<meta property="og:title" content="This Page Title"/>
<meta property="og:type" content="product"/>
<meta property="og:url" content="http://www.mywebaddress.com"/>
<meta property="og:image" content="http://www.myimage.jpg"/>
<meta property="og:site_name" content="My Site Name"/>
<meta property="fb:admins" content="10101010101"/>
<meta property="og:email" content="hello@mywebaddress.com"/>
<meta property="og:description" content="Description of my product."/>
I then have a 'like' button with this code:
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
<div class="fb-like" data-href="http://thispagesurl" data-send="true" data-width="350" data-show-faces="false"></div>
To my eye, everything seems to replicate what can be found on the Facebook Developers page but when i 'like', Facebook is seemingly only picking up on the page title and general info.
I have tried to 'debug' the page using their Object debugger, and i get these warnings:
Inferred Property The og:url property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property The og:title property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property The og:image property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property The og:locale property should be explicitly provided, even if a value can be inferred from other tags.
As far as i can tell, i have followed Facebook's instructions to the letter, but i have no joy. Can anyone point out if i'm doing anything wrong?
Thanks in advance, Dan
Are those tags on 'http://www.mywebaddress.com'?
Bear in mind the linter will follow the og:url tag as this tag should point to the canonical URL of the piece of content - so if you have a page, e.g. 'http://mywebaddress.com/article1' with an og:url tag pointing to 'http://mywebaddress.com', Facebook will go there and read the tags there also.
Failing that, the most common reason i've seen for seemingly correct tags not being detected by the linter is user-agent detection returning different content to Facebook's crawler than the content you're seeing when you manually check
