You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 06-x-www-form-urlencoded.go
    path of file: ./repos/gout/_example
    
    the code of the file until where you have to start completion: package main

import (
	"fmt"
	"github.com/gin-gonic/gin"
	"github.com/guonaihong/gout"
	"time"
)

// 使用SetWWWForm 接口设置x-www-form-urlencoded格式数据
// 下面的代码有 map/array/struct 使用example
type testWWWForm struct {
	Int     int     `form:"int" www-form:"int"`
	Float64 float64 `
    
func arrayExample() {
	fmt.Printf("====2.===============www-form=====use gout.A==\n\n")
	// 2.第一种方式，使用gout.A
	err := gout.POST(":8080/post").
		Debug(true).
		SetWWWForm(gout.A{
			"int", 3,
			"float64", 3.14,
			"string", "test-www-Form",
		}).
		Do()
	if err != nil {
		fmt.Printf("%s\n", err)
		return
	}
}
