阿里云香港轻量24抢购程序

因为需要买这个，手抢累，手撸了段代码。
这程序本身意义不大，不过可以做为阿里SDK的范本，比如我还需要写一个流量到了自动关机的脚本。

package main

import (
	"fmt"
	"os"

func CreateClient(Key, Secret string) (_result *swas_open20200601.Client, _err error) {
	config := &openapi.Config{

	}
	config.Endpoint = tea.String("swas.cn-hongkong.aliyuncs.com")
	_result = &swas_open20200601.Client{}
	_result, _err = swas_open20200601.NewClient(config)
	return _result, _err

func main() {

	if err != nil {

		} else {
			fmt.Printf("%d - Success! Please check it in your aliyun console.\n", i)
			break
		}
	}

	fmt.Println("Done")
