如何在外部网站内访问 Facebook 粉丝专页照片

Question

我们正在尝试利用 facebook 照片托管，并允许我们的访问者通过我们的网页查看已上传到粉丝墙的照片。

有人知道如何实现吗？

提前致谢！ 史蒂文。

使用社交图谱，您可以执行此操作，前提是脚本具有您的 Facebook 页面应用 ID 的访问令牌，或者您的照片权限设置为完全公开。

使用社交图谱，您基本上可以通过类似 REST 的 Web 服务访问照片。 webservice调用会返回一个dataExample的JSON对象：

https://graph.facebook.com/cocacola/albums

（可口可乐粉丝专页相册）

因此，第一步是使用上述 URL 检索相册。 遍历相册，获取想要的相册的对象ID。

{
         "id": "455377148305",
         "from": {
            "name": "Coca-Cola",
            "category": "Company",
            "id": "40796308305"
         },
         "name": "Coca-Cola Fanmeile FIFA WM 2010",
         "link": "http://www.facebook.com/album.php?aid=249745&id=40796308305",
         "count": 20,
         "type": "normal",
         "created_time": "2010-10-22T15:53:36+0000",
         "updated_time": "2010-10-22T15:55:23+0000",
         "comments": {}
},

获得对象 ID 后，只需将其作为图形 URL 的第一个参数即可访问它。例如：

https://graph.facebook.com/40796308305

从那里，您应该能够获取图像的实际 URL（取决于权限设置）

{
   "id": "40796308305",
   "name": "Coca-Cola",
   "picture": "http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs236.ash2/50516_40796308305_7651_s.jpg",
   "link": "http://www.facebook.com/coca-cola",
   "category": "Company",
   "website": "http://www.coca-cola.com",
   "username": "coca-cola",
   "products": "Coca-Cola is the most popular and biggest-selling soft drink in history, as well as the best-known product in the world.\n\nCreated in Atlanta, Georgia, by Dr. John S.

Coca-Cola was introduced in 1886, patented in 1887, registered as a trademark in 1893 and by 1895 it was being sold in every state and territory in the United States. In 1899, The Coca-Cola Company began franchised bottling operations in the United States.\n\nCoca-Cola might owe its origins to the United States, but its popularity has made it truly universal. Today, you can find Coca-Cola in virtually every part of the world.",
