Summary of Changes
Hello @gaby, 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 significantly enhances the robustness and accuracy of the Ctx.Is
method, which is responsible for content type comparison. The changes ensure that content type checks are more resilient to variations in header formatting, such as case differences, extraneous whitespace, and the presence of parameters, by implementing a more standard-compliant parsing and comparison logic.
Highlights
- Improved
Ctx.Is
method logic: TheIs
method inctx.go
has been refactored to correctly parse and compare content types. It now extracts the primary content type by ignoring parameters (e.g.,charset=utf-8
), trims any leading or trailing whitespace, and performs a case-insensitive comparison usingutils.EqualFold
. - Enhanced test coverage for content type comparison: New test cases have been added to
ctx_test.go
to validate the improvedIs
method's behavior. These tests specifically cover scenarios involving case-insensitive comparisons with content types that include parameters (e.g.,APPLICATION/JSON; charset=utf-8
) and ensure correct handling of subtype mismatches (e.g.,application/json+xml
should not matchjson
).

Code Review
The pull request improves the Is
method in ctx.go
to perform case-insensitive content type comparison and adds tests to verify the behavior. The changes involve trimming whitespace and folding case before comparison, and adding tests for case-insensitivity and subtype mismatch.
