在参考ChatGPT给出的choose + rate limit组合后,我们也发现另一个选项。使用rate-limit-by-key策略实现对特定IP的速率限制。 rate-limit-by-key 策略:https://docs.azure.cn/zh-cn/api-management/api-management-access-restriction-policies#LimitCallRateByKey, 可以对调用速率进行限制,使指定时段的调用不超出指...
What are my options for implementing API rate limits? Hard Stop:This means an API consumer will get an Error 429 when they call your API if they are over their limit. Soft Stop:In this case, you might have a grace period where calls can continue to be made for a short period after ...

使用 rate-limit-by-key 策略实现对特定IP的速率限制。 rate-limit-by-key 策略:docs.azure.cn/zh-cn/api, 可以对调用速率进行限制,使指定时段的调用不超出指定的数目,避免单个密钥的 API 使用量暴增。 密钥的值可以是任意字符串,通常使用策略表达式来提供密钥。 可以添加可选增量条件,指定在决定是否到达限制值...
For example, you might set your API quota at 5,000 calls per month. (Remember, you can combine this quota with a rate limit, such as 20 TPS.) The quota time window is activated when that first API call is made. Once the time window lapses, the counter resets to zero. It remains ...
