middleware for path-based authentication of labstack echo. Best when using apikey for path.
example) https://example.com/api/this_is_api_key
This this_is_api_key part can be dynamically submitted to authentication.
For example, whether apikey is active, RateLimit is not exceeded, etc.
Much of this code is based on key_auth.go in labstack/echo and its test code.
package main
import (
pa "github.com/bootjp/echo_middleware_path_auth"
"github.com/labstack/echo/v4"
"github.com/labstack/echo/v4/middleware"
)
func main() {
e := echo.New()
// group route
e.Group("/api/:apikey", pa.PathAuth("apikey", func(auth string, c echo.Context) (bool, error) {
// add your logic
return true, nil
}))
// single route
yourHttpHandler := func(c echo.Context) error { return c.String(200, "OK") }
yourPathAuthLogic := func(auth string, c echo.Context) (bool, error) {
return true, nil
}
e.GET("/api/:apikey", yourHttpHandler, pa.PathAuth("apikey", yourPathAuthLogic))
// with config
config := pa.PathAuthConfig{}
config.Skipper = middleware.DefaultSkipper
config.Param = "apikey"
config.Validator = yourPathAuthLogic
e.GET("/api/:apikey", yourHttpHandler, pa.PathAuthWithConfig(config))
