Facebook 的 Graph API 调用限制是多少？
我们对 facebook 的 graph api 的调用次数有限制吗？ 如果存在，那么每个应用程序每天可以拨打多少个电话？
Is there any restriction in number of calls we make to facebook's graph api?
and If it is there then how many calls can we make per app daily?

另一个论坛对此问题的最佳答案，来自 Ash Rust，2010 年：
截至 2015 年 10 月，上述信息已过时。根据 https://developers.facebook.com/docs/graph-api/advanced/rate-limiting
The best answer to this question from another forum, from Ash Rust in 2010:
The above information is now obsolete as of October 2015. It's now 200 API calls per user in any given 60 minute window according to https://developers.facebook.com/docs/graph-api/advanced/rate-limiting
现在官方：
每个应用程序分配200次API调用用户在任何给定的 60 分钟窗口内。
根据截至2015 年 10 月 7 日的 Facebook 文档，Graph API 的速率限制的工作原理如下：
速率限制，对该应用程序进行的所有调用都将受到限制，而不仅仅是在
每个用户的基础。
前一天有并添加今天的新登录。这给出了一个基础
您的应用程序拥有的用户数量。
举例来说，如果您的应用昨天有 10 个用户，今天有 5 个新登录，那么您的用户基数将为 15 个。这意味着您的应用程序可以在任何 60 分钟的窗口内进行 ((10 + 5) * 200) = 3000 个 API 调用。

Facebook 现在有一个速率限制仪表板，更容易看到如果您的应用程序的速率超出限制。它看起来像这样：
Now it's official:
Each app is given an allotment of 200 API calls per user in any given 60 minute window.
From the Facebook documentation as of October 7th 2015, here's how rate limiting on the Graph API works:
rate limit, all calls made for that app will be limited not just on a
per-user basis.
had the previous day and adding today's new logins. This gives a base
number of users that your app has.
As an example, if your app had 10 users yesterday and 5 new logins today, that would give you a base of 15 users. This means that your app can make ((10 + 5) * 200) = 3000 API calls in any 60 minute window.
More information here: https://developers.facebook.com/docs/graph-api/advanced/rate-limiting
--Update as of April 12th 2016--
Facebook has now a Rate Limit Dashboard, which is much easier to see if your app's rate limit is exceeding. It looks like this:
根据 Facebook 开发政策“I. 特性和功能”，唯一的限制是：
（Mau的意思是月用户）
它没有说超过限制后他们会做什么...
今天我已经跑到这个限制了：
总体而言，每个表都有不同的限制集，在大多数情况下，每个 fql 不会返回超过 30 个对象。另外，在我看来，您可以超出一张表的限制，同时您可以访问不同的表，问题是 api 是否对所有用户或仅对具有以下权限的用户被阻止（超出限制后）超出限制了……反正超出限制后你要等10分钟左右，还好。
因此从技术上讲，您每 10 分钟最多可以在表 mail_fql 中获取 300*30 个对象。
According to Facebook dev policies "I. Features and Functionality" the only limits are:
(Mau means monthly users)
It does not say what will they do after exceeding the limits...
Today I have ran to this limitation:
Overall every table has different set of limits, in most of the cases fql wont return more than 30 objects per fql. Also it seems to me that you can exceed the limits to one table and at the same time you can access different table, the question is whether the api is blocked (after exceeding the limit) for all the user or only for the user that has exceeded the limits... Anyway, after you exceed the limit you have to wait for about 10 minutes, than it is okay.
So technically speaking you can get at most 300*30 objects per 10 minutes in table mailbox_fql.

用户级别速率限制
此速率限制适用于除广告 api 之外的所有 api 调用的用户级别。
速率限制在滑动窗口上实时发生。
每个呼叫都会分配一个分数。最大分数为 n。
用户根据拨打的电话随着时间的推移累积分数。
当达到最大分数时，抛出节流错误。
错误，代码：17，消息：已达到用户请求限制
应用程序级别速率限制
此速率限制在应用程序级别全局应用。广告 API 调用被排除在外。
速率限制在过去一小时的滑动窗口上实时发生。
收集每个应用程序的调用和查询次数、花费的 CPU 时间、使用的内存等统计信息。
每个资源乘以给定应用程序的每月活跃用户数都有一个限制。
当应用程序使用超过其允许的资源时，会引发错误。
错误，代码：4，消息：已达到应用程序请求限制，请

From facebook documentation
User Level Rate Limiting
This rate limiting is applied at the user level for all api calls except for ads apis.
Rate limitations happens real time on sliding window.
Each call is assigned a score. There is a max score of n.
User accumulates a score over time based on the calls made.
When the max score is reached, the throttling error is thrown.
Error, Code: 17, Message: User request limit reached
App Level Rate Limiting
This rate limiting is applied globally at the app level. Ads api calls are excluded.
Rate limiting happens real time on sliding window for past one hour.
Stats is collected for number of calls and queries made, cpu time spent, memory used for each app.
There is a limit for each resource multiplied by monthly active users of a given app.
When the app uses more than its allowed resources the error is thrown.
Error, Code: 4, Message: Application request limit reached

根据 FB 文档，批次中的每个元素都算作单独的调用。
请检查：https://developers.facebook.com/docs/graph -api/发出多个请求
https://developers.facebook.com/docs/marketing-api/api -速率限制
According to FB docs, each element in a batch counts as a separate call.
