Facebook Graph API：获取帖子/状态附加的照片 [英] Facebook Graph API: Get post/status attached photos

问题描述

如何在组中获得多个附件的帖子/状态？

How can one get multiple attachments of a post/status in a group?

例如：某个成员写入并添加多张照片的组状态

For example: A group status that some member wrote and added multiple photos to..

目前，我正在使用Graph api来获取group_id / feed的组流，并且无法查看附加到单个状态的图像 - 从Facebook本身访问Feed可以验证状态附近有几张照片。

Currently I am using Graph api to get the group stream with group_id/feed and unable to see images attached to a single status - while accessing the feed from Facebook itself I can validate that there are few photos attached to the status.

使用FQL可以使用以下查询获取附件：

Using FQL it is possible to get the attachments with the following query:

SELECT attachment FROM stream WHERE post_id = each_post_id

SELECT attachment FROM stream WHERE post_id = each_post_id

考虑到我将不得不发送每个帖子的请求，FQL很快就会消失，我正在寻找一个

Considering I will have to send this request per post and that FQL will soon be gone I am searching for an alternative.

推荐答案

我正在寻找一个解决方案，实际上只是找到了。

I was looking for a solution for this as well and actually just found it.

Facebook Platform changelog 说如下：

/v2.1/ {post-id}现在将返回附加到帖子的所有照片：
以前版本的API只有第一张照片返回一个
的帖子。这消除了使用FQL获取所有帖子的照片的需要。

/v2.1/{post-id} will now return all photos attached to the post: In previous versions of the API only the first photo was returned with a post. This removes the need to use FQL to get all a post's photos.

有了这个知识，我去了一个 Graph Api Explorer ，并找到一个添加了2个附件的帖子。

With this knowledge I went to the Graph Api Explorer and found a post that had 2 attachments or more added to it.

找到帖子后，发贴号，我尝试了Facebook告诉我要做的请求：

After finding the post, and with that the post id, I tried the request Facebook told me to do:

/v2.1/ {post_id}

/v2.1/{post_id}

这不给你所需的结果。关于浏览器的好处是，您可以搜索要添加到请求中的字段。

This does NOT give you the desired result. The nice thing about the explorer is that you can search for fields you want to add to your request.

您要添加附件复数）字段。注意：可能图形api资源管理器仅显示附件（单数）字段。这是不对的。

You want to add the attachments (plural) field. NOTE: It might be that the graph api explorer only shows the attachment (singular) field. This is NOT right.

所以，总结一下：

1. 获取帖子


2. 向图api创建一个新的请求，如下所示：/v2.1/ {post_id}？fields = attachments

然后阅读结果以获取所需的附件。

Then read the result to get your desired attachments.

我希望这可以帮助您，因为我一直在努力一段时间。

I hope this helps you out as I have been struggling for a while as well.

KR

PS：这是用户测试的，而不是一个组，但它应该基本相同。

PS2：这只是一个解释如何获得单个帖子的附件。您还可以将附件字段添加到 / me / home egde中，以便在每个帖子中立即获取所有附件：

PS: This is tested with a user and not a group, but it should be basically the same.
PS2: This is just an explanation of how you get attachments of a single post. You can also add the attachments field to the /me/home egde to immediately get all attachments at every post like so:

我/ home？fields = message，from，附件

me/home?fields=message,from,attachments

PS3：权限你需要是

PS3: The permissions you need are

1. user_status


2. read_stream


3. user_photos


4. user_videos

1. user_status
2. read_stream
3. user_photos
4. user_videos

Facebook在这件事上不是很清楚，很难想像这样的事情。所以我希望这将帮助所有寻求这个解决方案的人。

Facebook is not very clear on this matter and it is very hard to figure things out like this. So I hope this will help everyone that is searching for this solution.
