Trailing Slash

Todo o middleware principal fica no pacote middleware:

import "github.com/labstack/echo/v5/middleware"

Adicionar barra final

O middleware Add trailing slash adiciona uma barra final à URI do request.

Uso

e := echo.New()
e.Pre(middleware.AddTrailingSlash())

Remover barra final

O middleware Remove trailing slash remove uma barra final da URI do request.

Uso

e := echo.New()
e.Pre(middleware.RemoveTrailingSlash())

Configuração customizada

e := echo.New()
e.Use(middleware.AddTrailingSlashWithConfig(middleware.AddTrailingSlashConfig{
  RedirectCode: http.StatusMovedPermanently,
}))

O exemplo acima adiciona uma barra final à URI do request e redireciona com 301 - StatusMovedPermanently.

  RedirectCode int
}
