在 Facebook Graph API 上的 venue-id/events 上获取事件 attending_count

Question

我正在尝试在 Facebook 图 API 上获取 attending_count。我知道通过 /event-id?fields=attending_count 我会获得此信息，但在会场内尝试此信息时 /venue-id/events?fields=attending_count 不会显示。

这是我正在尝试的：

https://graph.facebook.com/v2.2/217733628398158/events?fields=id,cover,name,venue,description,ticket_uri,start_time,attending_count&access_token=....

有什么想法吗？

Answer 1

Event 对象上没有 attending_count 字段，但有一个 attending 边：

您为什么要获取场地页面 ID 上的 attending_count？这没有多大意义。

您可以像这样使用 summary 获取与会者的绝对数量

/217733628398158/events?fields=id,cover,name,venue,description,ticket_uri,start_time,attending.summary(true).limit(1)

为了减少图表 API 返回的数据量，我添加了 .limit(1) 每个事件只返回一名与会者，但无论如何都会生成摘要计数。如果您需要整个列表，请删除 limit 参数。

所以，returns
