The tag did not match exactly

[xishengcai]

Description

	type tHeader struct {
		Limit  int `header:"limit"`
		Limit2 int `json:"limit"`
	}

If my http request header has limit , I want only math tag: "header:"limi"

Expectations

func TestHeaderBinding(t *testing.T) {
	h := Header
	assert.Equal(t, "header", h.Name())

	type tHeader struct {
		Limit  int `header:"limit"`
		Limit2 int `json:"limit"`
	}

	var theader tHeader
	req := requestWithBody(http.MethodGet, "/", "")
	req.Header.Add("limit", "1000")
	require.NoError(t, h.Bind(req, &theader))
	assert.Equal(t, 1000, theader.Limit)
	assert.Equal(t, 0, theader.Limit2)

	req = requestWithBody(http.MethodGet, "/", "")
	req.Header.Add("fail", `{fail:fail}`)

	type failStruct struct {
		Fail map[string]any `header:"fail"`
	}

	err := h.Bind(req, &failStruct{})
	require.Error(t, err)
}

open ai has been give answer:

	if vKind != reflect.Struct || !field.Anonymous {
		if _, exists := field.Tag.Lookup(tag); exists {
			ok, err := tryToSetValue(value, field, setter, tag)
			if err != nil {
				return false, err
			}
			if ok {
				return true, nil
			}
		}
	}
