如何获取由群组管理员以外的人上传的 Facebook 群组照片？ （通过 JavaScript）
我正在为一个反映 Facebook 群组的群组建立一个网站，我想从 Facebook 中提取该群组的所有照片并将其显示在我的网站上。但这些照片可能是由完全陌生的人上传的：所以基本上，一个随机的人拍摄该团体的照片并将其上传到 Facebook，我们希望该照片在我们的网站上可见。
我可以想到三种方法来执行此操作：
将照片标记为组并查找标记为组的所有照片
您似乎无法通过 Graph API 访问标记为特定组的照片（请证明我错了）。我可以在 FQL 中执行此操作：
SELECT images FROM photo WHERE pid in (SELECT pid FROM photo_tag WHERE subject=GROUP_ID)，但据我所知，这需要网站访问者登录 Facebook 才能创建FB 会话，这不好。在我们的 FB 页面上“分享”照片，并以某种方式找到我们在我们的页面上分享的所有照片
我似乎想不出一种方法来将共享对象的搜索限制为照片，但我愿意接受建议。
自行重新上传照片到群组控制相册
嗯。前两个选项不涉及在 facebook 上创建任何新对象，并且是首选，但我很难做到其中任何一个，这让我不得不从 facebook 下载照片并在我们的应用程序中重新上传它们。自己的相册，我知道怎么展示。
请告诉我有比#3更好的方法吗？
I'm building a website for a group that mirrors a facebook group, and I'd like to pull any photos of the group from facebook and display them on my site. BUT the photos might be uploaded by perfect strangers: so basically, a random person takes a picture of the group and uploads it to facebook, and we want that photo to be visible on our website.
I could think of three ways to do this:
tag the photo as the group and find all photos tagged as the group
It seems you can't get Graph API access to photos tagged as a particular group (please prove me wrong). I can do this in FQL:
SELECT images FROM photo WHERE pid in (SELECT pid FROM photo_tag WHERE subject=GROUP_ID), but from what I can tell, this requires the website visitor to log into facebook to create a FB session, which is no good.'share' the photo on our FB Page and somehow find all photos we've shared on our page
I can't seem to think of a way to restrict a search of shared objects to photos, but I'm open to suggestions.
re-upload the photo ourselves into a group-controlled photo album
meh. The first two options don't involve creating any new objects on facebook, and would be preferred, but I'm having a hard time doing either of them, which leaves me with downloading the photos from facebook and uploading them all over again in our own photo album, which I know how to show.
Please tell me there's a better way to do it than #3?

我编写了一个 PHP 小应用程序，它将我的 Facebook 新闻提要 (/me/home) 转换为 RSS，并可以通过 Google Reader 进行订阅。虽然我的项目与发布无关，但我认为您需要一些与我在那里使用的offline_access类似的技术。
所以，首先，你需要一个虚拟的 Facebook 用户帐户，该帐户有权在群组中读取和发布（因为这是一个公共群组，所以可以避免一些麻烦）
使用“offline_access”和其他方式获取该用户的 access_token发布所需的范围，例如此处的直接 url 示例 http://developers.facebook.com/docs/reference/dialogs/oauth/
然后...将访问令牌硬编码到 PHP 脚本中
因此，该脚本将充当该用户。浏览镜像网站的任何人甚至不需要 Facebook 帐户。
解决了认证问题之后，剩下的就是简单的查询、上传、发布的编码了。希望这会有所帮助
I've wrote a little PHP app which turned my Facebook news feed (/me/home) into RSS, and make it possible to subscribe by Google Reader. Although my project has nothing to do with publishing, I think you'll need some similar technique with the offline_access I've used there.
So, first of all, you'll need dummy Facebook user account which have the permission to read and publish in the group (since that's a public group so save you from some trouble)
Get the access_token of this user with "offline_access" and other scopes required for publishing like direct url example here http://developers.facebook.com/docs/reference/dialogs/oauth/
Then... hard code the access token into the PHP script
Therefor, this script would act as that user. Anyone browsing the mirrored website doesn't even need a Facebook account.
After solving the authentication issue, the rest just simple coding for querying, uploading, publishing. Hope this would help
