Rate limit for traefik using json data from request-CodePudding

I'd like to set rateLimit for requests where in json data present param with sample value

Example

curl -X 'POST'   'http://127.0.0.1/'   -H Host:whoami.docker.localhost   -H 'accept: application/json'   -H 'Content-Type: application/json'   -d '{
  "sender": "Tester",
  "receiver": [
    "receiver1" 
  ],
  "text": "Text",
  "service": "service" 
}'

I need limit 100rps for sender=Tester, other senders must have no rateLimit

I tried such config:

[http.routers]
   [http.routers.whoami_1]
      rule = "Host(`whoami.docker.localhost`)&&Query(sender=Tester)"
      service = "whoami"
      entrypoints = ["web"]
      middlewares = ["test-ratelimit"]

[http.middlewares]
  [http.middlewares.test-ratelimit.rateLimit]
    average = 100

But received

404 page not found

How can I get param from json data in request and set rule for routes or middleware?

CodePudding user response：

Traefik does not provide middlewares to extract the JSON payload from the request.

You can probably try to create a custom plugin extracting the value and applying the rate limiting on its own.
