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

    "fmt"
    "os"

func CreateClient(Key, Secret string) (_result *swas_open20200601.Client, _err error) {
    config := &openapi.Config{
        AccessKeyId:     tea.String(Key),
        AccessKeySecret: tea.String(Secret),
    }
    config.Endpoint = tea.String("swas.cn-hongkong.aliyuncs.com")
    _result = &swas_open20200601.Client{}
    _result, _err = swas_open20200601.NewClient(config)

    now := time.Now().In(location)
    tomorrowMidnight := now.Truncate(24 * time.Hour).Add(24 * time.Hour)
    time.Sleep(time.Until(tomorrowMidnight))
