## What this PR does / why we need it: This PR addresses #10208 by checking whether the request method is valid. For invalid methods we set `method="invalid_method"` label so that operators can stil see traffic in the metrics but without unbound label value. ## Types of changes <!--- What types of changes does your code introduce? Put an `x` in all the boxes that apply: --> - [x] Bug fix (non-breaking change which addresses an issue) - [ ] New feature (non-breaking change which adds functionality) - [ ] CVE Report (Scanner found CVE and adding report) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation only ## How Has This Been Tested? I tested by building the image locally using `make build && make image` and running the image in minikube. The change has a fairly narrow scope so should be low risk. ## Checklist: <!--- Go over all the following points, and put an `x` in all the boxes that apply. --> <!--- If you're unsure about any of these, don't hesitate to ask. We're here to help! --> - [ ] My change requires a change to the documentation. - [ ] I have updated the documentation accordingly. - [x] I've read the [CONTRIBUTION](https://github.com/kubernetes/ingress-nginx/blob/main/CONTRIBUTING.md) guide - [x] I have added unit and/or e2e tests to cover my changes. - [x] All new and existing tests passed. |

Ingress NGINX Controller
Overview
ingress-nginx is an Ingress controller for Kubernetes using NGINX as a reverse proxy and load balancer.
Learn more about Ingress on the Kubernetes documentation site.
Get started
See the Getting Started document.
Do not use in multi-tenant Kubernetes production installations. This project assumes that users that can create Ingress objects are administrators of the cluster. See the FAQ for more.
Troubleshooting
If you encounter issues, review the troubleshooting docs, file an issue, or talk to us on the #ingress-nginx channel on the Kubernetes Slack server.
Changelog
See the list of releases for all changes.
For detailed changes for each release, please check the changelog-$version.md file for the release version.
For detailed changes on the ingress-nginx helm chart, please check the changelog folder for a specific version.
CHANGELOG-$current-version.md file.
Supported Versions table
Supported versions for the ingress-nginx project mean that we have completed E2E tests, and they are passing for the versions listed. Ingress-Nginx versions may work on older versions, but the project does not make that guarantee.
