当我使用API https://api.vimeo.com/oauth/access_token从我的服务器请求访问令牌时，我收到以下响应。此API是否有一些变化。 需要帮助，因为这是服务器，为什么会出现此响应。

答案 0 :(得分：0)
您正在达到速率限制，并且您的应用程序向Vimeo API发出了太多请求。限额禁令在超过限额后约60分钟后到期。最佳做法是在返回429错误时立即停止向API发出请求，否则您可能会推迟速率限制禁止重置时间。
实际的速率限制因不同的帐户级别和端点而异，因此请始终参考实际值的响应标头。以下是标题的示例（显然，您的具体值会有所不同）：
X-RateLimit-Limit →500
X-RateLimit-Remaining →499
X-RateLimit-Reset →2018-02-07T15:47:46+00:00
避免达到Vimeo API速率限制的最佳方法是在所有请求中使用字段过滤器。如果请求未经过滤，Vimeo将返回最低费率限制，无论帐户类型或费率限制等级如何。
