速率限制

- 例如,REST API 调用的默认速率限制为每小时 150 个请求。
For example, the default rate limit for REST API calls is 150 requests per hour. - 关于速率限制还有最后一点要注意:允许客户机每小时发出 100 个请求,从他们的第一个请求开始,不包括 POST 更新。
One final note about rate limits: Clients are allowed 100 requests per hour, starting from their first request, not including POST updates. - 只要超过速率限制,Twitter 就会返回一条 400 错误消息,因此您需要考虑在您这一端实现本地缓存。
Any time you exceed the rate limit, Twitter returns a 400 error message, so you need to think about implementing local caches on your side of things.
