使用字段参数查询FB Graph API feed？ [英] Querying FB Graph API feed with fields parameter?

问题描述

当Facebook Facebook被Facebook Graph API添加了对象）

what happens when a Facebook page is queried for its feed with Facebook Graph API (JS SDK) and a URL parameter fields (like for the post object) is added?

我想从Feed只加载帖子id，分享，喜欢和评论，因为页面非常活跃，JSON中的文本数据2天约为2MB（25个项目）...

I would like to load from the feed only the posts id's, shares, likes and comments, because the page is pretty active and the text data in JSON for 2 days is about 2MB (25 items)...

我希望可以这样做： FB.api（'/ SomePage？fields = id，shares，likes'），但是我想你可以访问的唯一字段是直接的子代（对于 feed ，即数据& 分页）？如果不幸的是这种情况，是否有任何其他方式可以从日期x到日期y检索所有帖子，而无需下载整个Feed？

I would hope one could do like this: FB.api('/SomePage?fields=id,shares,likes'), but I suppose the only fields you can access are the direct children (for feed, that is data & paging)? If this unfortunately is the case, is there any other way to retrieve all posts from date x to date y without downloading the entire feed?

推荐答案

这是不正确的。 feed edge基本上是一个Post对象的数组。您可以使用现场扩展以及时间分页，如下所示：

That's not correct. The feed edge is basically an array of Post objects. You can use the Field Expansion together with time pagination as follows:

GET /{page_id}/feed?fields=id,shares,likes.summary(true)&since={start_unix_timestamp}&until={end_unix_timestamp}
