如何在外部网站访问Facebook粉丝页面照片

Question

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

有没有人知道这是如何实现的？

提前致谢！ Steven。

使用社交图谱，您可以执行此操作，前提是该脚本具有您的Facebook页面应用程序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Web服务的REST访问照片。该Web服务调用将返回dataExample的JSON对象：

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

（相册为可口可乐的粉丝专页）

因此，第一步将检索使用类似上面的一个URL的相册。 遍历相册并获取所需专辑的对象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": {} 
}, 

只要将对象ID设置为图形URL的第一个参数，就可以访问它。例如：

https://graph.facebook.com/40796308305 

从那里，你应该能够抓住实际的URL的图像（根据权限设置）

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.",
