有没有办法对 express nodejs 中的每个 api 键使用不同的速率限制？

Question

is there a way to use different rate limit for each api key in express nodejs?

for example api key "guest" has a rate limit of 500 requests per day and api key "key" has a rate limit of 1000 requests per day.

Answer 1

the simple solution is to use an npm package called express-rate-limit , it's a popular one and express recommend to use it.

If the package doesn't work for you, it can be implemented using redis , redis is a memory database, so you can create a record with a sliding time. When a request come in you can upadte or create the record, if the limit was reached you block the request, that logic can be implemented in a middleware.
