如何获得Facebook页面的平均评分和评分数？ [英] How to get average rating and number of ratings of a facebook page?

问题描述

我正在尝试从Facebook页面中查找评分数和平均值。

我通过oauth获得了长期的页面标记，可以访问除了这些领域。我是否缺少某些东西，或者他们不会像谷歌的地方或四方面的API那样返回这些？

我可以通过/ {page-id} /评分收集个人评分，但是如果我有一个1,000个评论的页面，这些将被归还？这是计算我自己的平均值/计数的可靠替代方案吗？

Google地方评分数是一个隐藏字段（API文档中未显示）。希望Facebook可能有其中一个？？

解决方案

您可以使用 / page / ratings 节点。图表api文档中提到的F​​acebook页面没有一个总评级属性。但是，您可以通过图表API获得的各个评分计算总评级。

图api是相当可靠的，你应该几乎每个帖子通过它。是的，你可以计算自己的平均值/计数原因，当处理1000评论，即使你错过1或2，它将不会有很大的区别，因为评级在（1-5）之间。

注意：

这里在 page / feed

所有这些衍生边均具有完全相同的阅读结构，
然而/ feed应该用于所有出版目的。他们都是
的限制参数为250个帖子的上限。
指定任何更高的限制会抛出一个错误。

所以要获取1000个帖子，请确保您将使用分页。

I am trying to find the count of ratings and the average value from facebook pages.

I obtained a long term page token via oauth and can access everything but these fields. Am I missing something, or do they not return these like google places or foursquare APIs do ?

I can collect individual ratings via /{page-id}/ratings, however, if I have a page with 1,000 reviews, will all these be returned? Is it a reliable alternative to calculate my own averages/count?

The google places rating count is a hidden field (not shown in the API docs). Hoping there might be one of these for facebook...?

解决方案

You can get page ratings and review using /page/ratings node . There isn't an aggregate rating attribute for the facebook pages mentioned in the graph api docs .But you calculate the aggregate rating from the individual ratings obtained via graph api .

Graph api is pretty reliable and you should get almost every post via that . and yeah you can calculate your own averages/count cause when dealing with 1,000 reviews even if you miss 1 or 2 it won't make a big difference as ratings is between (1-5) .

note :

It is mentioned here at page/feed that

All of these derivative edges share the exact same reading structure, however /feed should be used for all publishing purposes. They all have an upper boundary for the limit parameter of 250 posts. Specifying any higher limit will throw an error.

So for obtaining something like 1000 posts , make sure you will be using paging .
