Summary of Changes

Hello @fzyzcjy, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request performs a minor refactoring within the consistent hashing policy module. It extracts repetitive header parsing logic into reusable helper functions. This change aims to make the code cleaner and easier to understand without altering the existing behavior or functionality of the router.

Highlights

  • Code Refactoring: Introduced new helper functions to encapsulate the logic for extracting header values, improving code readability and maintainability.
  • Header Extraction: Centralized the extraction of x-smg-target-worker and x-smg-routing-key headers into dedicated functions, replacing duplicated inline code.

Code Review

This pull request refactors header value extraction into helper functions to reduce code duplication. The change is a good improvement to code clarity and maintainability. I've suggested a small enhancement to the new helper function to make it even more reusable, which would allow simplifying another part of the code that has similar logic. I also noticed that the logic for implicit_key extraction doesn't seem to have dedicated test coverage, which could be a good addition for a future PR.
