Path params won't bind.

[chrislentz]

Can anyone help me understand why Echo wont bind my path parameters? The query param binds successfully, but the 2 path params are empty when I log the requestData struct after binding.

curl --location --request GET 'http://localhost:8181/test/param-one/param-two?test_query_one=query-one'

type TestRequest struct {
	TestParamOne string `param:"test_param_one"`
	TestParamTwo string `param:"test_param_two"`
	TestQueryOne string `query:"test_query_one"`
}

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

	app.GET("/test/:test_param_one/:test_param_two", func(c echo.Context) (err error) {
		var requestData TestRequest

		fmt.Println(c.Param("test_param_one")) // This works.
		fmt.Println(c.Param("test_param_two")) // This works.

		// Bind request data
		if err = c.Bind(&requestData); err != nil {
			fmt.Println(err)
			return err
		}

		fmt.Printf("%#v\n", requestData) // TestParamOne & TestParamTwo are empty. TestQueryOne binded sucessfully.

		return c.String(http.StatusOK, "OK")
	})

	app.Logger.Fatal(app.Start(":8181"))
}

// Log Output
2022/11/07 14:45:59 stdout: param-one
2022/11/07 14:45:59 stdout: param-two
2022/11/07 14:45:59 stdout: main.TestRequest{TestParamOne:"", TestParamTwo:"", TestQueryOne:"query-one"}

I was able to resolve the issue. It turns out I was running an outdated version of Echo. I upgraded to v4.9.1 and it is working as expected.

@chrislentz am using echo v4.12.0 and am facing this issue in my unit tests.
doing c.SetParamNames(), c.SetParamValues() in test doesn't make Bind() work for path params
