Exemplo

Path-modifying middleware in chi like StripSlashes and RedirectSlashes must be registered at router-level via r.Use() before routes, because per-route r.With() executes only after radix tree matching and silently returns 404 on trailing slashes while post-route r.Use() panics loudly.

O que costuma-se supor

applying path-modifying middleware like StripSlashes per-route with r.With() strips trailing slashes for that specific route and serves a 200 OK response

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• assert per-route With(StripSlashes) fails with 404 on trailing slash requests because tree matching precedes route middleware
• assert router-level Use(StripSlashes) strips trailing slashes and serves 200 before tree matching
• assert per-route With(RedirectSlashes) fails with 404 while router-level Use(RedirectSlashes) returns 301
• assert calling Use after route registration panics with frozen middleware chain error
