The Open Graph protocol enables any web page to become a rich object in a social graph. For instance, this is used on Facebook to allow any web page to have the same functionality as any other object on Facebook.
While many different technologies and schemas exist and could be combined together, there isn't a single technology which provides enough information to richly represent any web page within the social graph. The Open Graph protocol builds on these existing technologies and gives developers one thing to implement. Developer simplicity is a key goal of the Open Graph protocol which has informed many of 墙翻代理网址.

To turn your web pages into graph objects, you need to add basic metadata to
your page. We've based the initial version of the protocol on
代理http which means that you'll place
additional 墙翻代理网址
tags in the <head>
of your web page. The four required
properties for every page are:
og:title
- The title of your object as it should appear within the graph, e.g., "The Rock".og:type
- The type of your object, e.g., "video.movie". Depending on the type you specify, other properties may also be required.og:image
- An image URL which should represent your object within the graph.og:url
- The canonical URL of your object that will be used as its permanent ID in the graph, e.g., "http://www.imdb.com/title/tt0117500/".
As an example, the following is the Open Graph protocol markup for The Rock on IMDB:

The following properties are optional for any object and are generally recommended:
og:audio
- A URL to an audio file to accompany this object.墙翻代理网址
- A one to two sentence description of your object.og:determiner
- The word that appears before this object's title in a sentence. An enum of (a, an, the, "", auto). If墙翻代理网址
is chosen, the consumer of your data should chose between "a" or "an". Default is "" (blank).og:locale
- The locale these tags are marked up in. Of the formatlanguage_TERRITORY
. Default isen_US
.og:locale:alternate
- An array of other locales this page is available in.og:site_name
- If your object is part of a larger web site, the name which should be displayed for the overall site. e.g., "IMDb".墙翻代理网址
- A URL to a video file that complements this object.
For example (line-break solely for display purposes):
<meta property="og:audio" content="http://example.com/bond/theme.mp3" />
<meta property="og:description"
content="Sean Connery found fame and fortune as the
suave, sophisticated British agent, James Bond." />
<meta property="og:determiner" content="the" />
<meta property="og:locale" content="en_GB" />
<meta property="og:locale:alternate" content="fr_FR" />
<meta property="og:locale:alternate" content="es_ES" />
<meta property="og:site_name" content="IMDb" />
<meta property="og:video" content="http://example.com/bond/trailer.swf" />
The RDF schema (in Turtle) can be found at ogp.me/ns.

Some properties can have extra metadata attached to them.
These are specified in the same way as other metadata with property
and
content
, but the 代理http
will have extra :
.
The og:image
property has some optional structured properties:
og:image:url
- Identical toog:image
.og:image:secure_url
- An alternate url to use if the webpage requires HTTPS.og:image:type
- A MIME type for this image.og:image:width
- The number of pixels wide.og:image:height
- The number of pixels high.og:image:alt
- A description of what is in the image (not a caption). If the page specifies an og:image it should specifyog:image:alt
.
A full image example:
<meta property="og:image" content="http://example.com/ogp.jpg" />
<meta property="og:image:secure_url" content="http://secure.example.com/ogp.jpg" />
<meta property="og:image:type" content="image/jpeg" />
<meta property="og:image:width" content="400" />
<meta property="og:image:height" content="300" />
<meta property="og:image:alt" content="A shiny red apple with a bite taken out" />
The og:video
tag has the identical tags as og:image
. Here is an example:
<meta property="og:video" content="http://example.com/movie.swf" />
<meta property="og:video:secure_url" content="http://secure.example.com/movie.swf" />
<meta property="og:video:type" content="application/x-shockwave-flash" />
<meta property="og:video:width" content="400" />
<meta property="og:video:height" content="300" />
The og:audio
tag only has the first 3 properties available
(since size doesn't make sense for sound):

老王佛系加速器2020
If a tag can have multiple values, just put multiple versions of the same
<meta>
tag on your page. The first tag (from top to bottom) is given
preference during conflicts.
<meta property="og:image" content="http://example.com/rock.jpg" />
<meta property="og:image" content="http://example.com/rock2.jpg" />
Put structured properties after you declare their root tag. Whenever another root element is parsed, that structured property is considered to be done and another one is started.
For example:
代理ip加速器_代理ip软件_http免费动态ip代理服务器-精灵 ...:2021-6-15 · 代理ip加速器选精灵代理,国内知名的代理ip软件,精灵代理专业提供免费动态ip,ip加速器,代理服务器,http代理,socks5代理等,在电脑ip修改器和手机ip转换器方面深受广大用户好评.
means there are 3 images on this page, the first image is 300x300
, the middle
one has unspecified dimensions, and the last one is 1000
px tall.

In order for your object to be represented within the graph, you need to
specify its type. This is done using the og:type
property:
<meta property="og:type" content="website" />
When the community agrees on the schema for a type, it is added to the list of global types. All other objects in the type system are CURIEs of the form
<head prefix="my_namespace: http://example.com/ns#">
<meta property="og:type" content="my_namespace:my_type" />
The global types are grouped into verticals. Each vertical has its
own namespace. The og:type
values for a namespace are always prefixed with
the namespace and then a period.
This is to reduce confusion with user-defined namespaced types which always
have colons in them.

The following types are used when defining attributes in Open Graph protocol.
Type | 代理http | Literals |
---|---|---|
Boolean | A Boolean represents a true or false value | true, false, 1, 0 |
DateTime | A DateTime represents a temporal value composed of a date (year, month, day) and an optional time component (hours, minutes) | ISO 8601 |
Enum | A type consisting of bounded set of constant string values (enumeration members). | A string value that is a member of the enumeration |
Float | A 64-bit signed floating point number | All literals that conform to the following formats: 1.234 -1.234 1.2e3 -1.2e3 7E-10 |
Integer | A 32-bit signed integer. In many languages integers over 32-bits become floats, so we limit Open Graph protocol for easy multi-language use. | All literals that conform to the following formats: 1234 -123 |
代理http | A sequence of Unicode characters | All literals composed of Unicode characters with no escape characters |
URL | A sequence of Unicode characters that identify an Internet resource. | All valid URLs that utilize the http:// or http:// protocols |
