Facebook 如何使用 Graph API 获取实际照片 URL？

Question

可以使用 Graph api 获取 Facebook 图片的实际图片 url 吗？？

例如，对于下面的照片 http://www.facebook.com/photo.php?fbid=357755307655174

实际网址是 https://fbcdn-sphotos-a-a.akamaihd.net/hphotos-ak-ash4/252428_530045532341_5136_n.jpg

是否有一些图形 API 方法可以实现这一点？

Answer 1

• 来自 https://developers.facebook.com/docs/graph-api/using-graph-api :

By default, not all fields in a node or edge are returned when you make a query. You can choose the fields or edges that you want returned with the fields query parameter.

这就是为什么当您检索照片时，您可能只会得到 created_time、name 和 id。

• 来自 https://developers.facebook.com/docs/graph-api/reference/photo/ :

source 字段在最新的 API (v2.8) 中已弃用。请改用 images。

因此您的查询可能如下所示:

GET graph.facebook.com/{photo-id}?fields=images

响应应该是这样的:

{

"images":[
    {
        "height":358,
        "source":"https://scontent.xx.fbcdn.net/v/t1.0-9/15327427_585435148333529_xxxxxxxxxxxx_n.jpg?oh=xxxxxxxx&oe=xxxxxxxxx",
        "width":518
    },
    {
        "height":320,
        "source":"https://fb-s-c-a.akamaihd.net/h-ak-xtl1/v/t1.0-0/p320x320/15327427_xxxxxxxxxxxxxx_n.jpg?oh=xxxxxxxxxx&oe=xxxx&__gda__=xxxxxxxxxxxx",
        "width":463
    },
    {
        "height":130,
        "source":"https://fb-s-c-a.akamaihd.net/h-ak-xtl1/v/t1.0-0/p130x130/15327427_xxxxxxxxxxxxxx_n.jpg?oh=xxxxxxxxxxx&oe=xxx&__gda__=xxxxxxxxxxxxxxxxxx",
        "width":188
    },
    {
        "height":225,
        "source":"https://fb-s-c-a.akamaihd.net/h-ak-xtl1/v/t1.0-0/p75x225/15327427_xxxxxxxxxxxxxxx_n.jpg?oh=xxxxxxxxxxxxxxxxx&oe=xxxxxxxxxxxxxxxxxx&__gda__=xxxxxxxxxxxxxxxxxx",
        "width":325
    }
],
"id":"585435148333529"

}
