api - Google OAuth 2.0 API是否有速率限制？

Question

我正在考虑使用https://www.googleapis.com/auth/userinfo.email来获取用户的电子邮件地址，并且在Google自己的文档和Internet上的其他指南中已经看到了许多有关如何执行此操作的示例。

但是，我无法找到有关速率限制是什么的信息，或者甚至没有关于此的任何速率限制的信息。 Google API控制台列出了许多不同API的礼节性限制，但未提及OAuth 2.0 API。

有谁知道是否有限制，如果有限制，那是什么？

Answer 1

我可以肯定地说对Google的Authorization API的没有任何限制。
我知道这是因为它没有在Authorization API的服务条款内的任何地方声明任何限制。实际上，Terms of Service itself非常裸露:

Google Account Authentication APIs Terms of Service

Last modified: April 20, 2012 By using this API, you consent to bebound by these terms in addition to the Google APIs Terms of Service("API ToS") at https://developers.google.com/terms. Deprecation Policy

Google will announce if we intend to discontinue or make backwardsincompatible changes to this API or Service. We will use commerciallyreasonable efforts to continue to operate the Google AccountAuthentication APIs (exclusive of OAuth 2.0) without these changesuntil April 20, 2015, unless (as Google determines in its reasonablegood faith judgment):

required by law or third party relationship (including if there is achange in applicable law or relationship), or doing so could create asecurity risk or substantial economic or material technical burden.This Deprecation Policy doesn't apply to versions, features, andfunctionality labeled as "experimental."

After April 20, 2015, this Deprecation Policy will not apply.

如果有限制，Google通常必须将其放入ToS，因此我可以放心地说没有限制。
