This PR changes how the extractor expected error
ErrNoTokenInRequest
is checked.This allows implementations of the
Extractor
interface to wrap errors as suggested since Go 1.13. This is mainly interesting for external Extractor implementations.This is consistent with the direction the errors are refactored in the
jwt
package. I therefore allowed myself not to open an issue first.As the two are conceptually related, I could also open a PR towards that branch if that is desired but my understanding is that PR #136 focuses on the validation errors. @oxisto WDYT?
