Bind to custom type?

[StephanSchmidt]

How would I bind to a custom type?

type PathId string

(string for simplicity, I do want to do some conversions)

Have you tried?

package main

import (
	"errors"
	"github.com/labstack/echo/v4"
	"log/slog"
	"net/http"
)

type PathId string

type Payload struct {
	Path PathId `param:"path_id"`
}

func main() {
	e := echo.New()

	e.GET("/:path_id", func(c echo.Context) error {
		payload := Payload{}
		if err := c.Bind(&payload); err != nil {
			return echo.NewHTTPError(http.StatusBadRequest, err.Error())
		}
		return c.JSON(http.StatusOK, payload)
	})

	if err := e.Start(":8080"); err != nil && !errors.Is(err, http.ErrServerClosed) {
		slog.Error("server closed due to unexpected error", "err", err)
	}
}

Example:

x@x:~/code/echo$ curl http://localhost:8080/xxx
{"Path":"xxx"}

also you might want to read this PR #2607 this refers to interfaces to implement for custom binding logic

I would need to get in between, I want to do some conversion etc. (otherwise I would just use a string).

I will take a look at #2607 thanks.
