request help: how to use wildcards in paths with ApisixRoute CRD

[machadojoao]

Issue description

Hi, I have some APIs paths like:

/api/:id/my-entity1
/api/:id/my-entity2

I could not use the CRD ApisixRoute because it has a validation for this field that the wildcard must be at the end.

spec.http[0].match.paths[0] in body should match '^/[a-zA-Z0-9\-._~%!$&'()+,;=:@/]*\*?$'

But if I use the admin api directly (our by the dashboard), I'm able to use a wildcard at path like:

{ "uris": [ "/api/*/my-entity1", "/api/*/my-entity2" ], "name": "route, "priority": 0, "methods": [ "GET" ], "upstream_id": "2fa86803" "status": 1 }

Is there anyway to do this with CRDs?

Environment

• your apisix-ingress-controller version (output of apisix-ingress-controller version --long):
• your Kubernetes cluster version (output of kubectl version):
• if you run apisix-ingress-controller in Bare-metal environment, also show your OS version (uname -a):

Good catch!

I think we can change the rules.

The ApisixRoute "ar-iot-node" is invalid: spec.http.match.paths: Invalid value: "/assets/help/*/rulenode/*": spec.http.match.paths in body should match '^/[a-zA-Z0-9\-._~%!$&'()+,;=:@/]*\*?$'

I hit the same issue.

As a workaround, you can use regular expression matching. For example:

apiVersion: apisix.apache.org/v2
kind: ApisixRoute
metadata:
  name: speaker-topics-route
spec:
  http:
    - name: speaker-topics
      match:
        hosts:
          - conferenceapi.azurewebsites.net
        paths:
          - /*
        exprs:
          - subject:
              scope: Path
              name: topics
            op: RegexMatch
            value: "^/speaker/[^/]*/topics$"
        methods:
          - "GET"
      upstreams:
        - name: conference-api-upstream

See navendu.me/posts/batching-requests for full explanation.

Should we still change the rule or continue with this workaround?

This workaround works if there is only one ApiSixRoute with http[0].match.paths = /*
If you have two paths like that the second one will never be reached.

FYI @byblakeorriver I just tested it using apisix helm chart version 1.4.0 which is 3.3.0 application version and it worked for me.

Thank you! It looks like it is working for me now too!
