终端上扫用户的付款码，肯定没清键盘缓冲。。。所以，微信的付款码36位72位什么的全来了。。偏偏终端的哥们兼职的，只星期天处理公事。
能怎么样，擦屁股呗。。

{"level":"DEBUG","time":"2024-04-02T15:32:39.662+0800","app_id":"xxxxxxxx","msg":"placeorder: cartdata:xxxxxxx,amount:2500,barcode:131014308497832446131014308497832446"}

    if len(barcode) > 18 && len(barcode)%18 == 0 {
        times18 := len(barcode) / 18
        log.Log.Debugf("[%s] Buggy! Barcode is %d times 18, cutting it to 18", orderno, times18)
        barcode = barcode[(times18-1)*18 : times18*18]
    }

太方便了，我以前居然不知道，还得让gpt教我

type Config struct {
    Database struct {
        User          string `yaml:"user"`
    } `yaml:"database"`
}
var GlobalConfig Config

executablePath, _ := os.Executable()
yamlPath := filepath.Join(filepath.Dir(executablePath), "xxxx.yaml")
yamlFile, _ := os.ReadFile(yamlPath)
yaml.Unmarshal(yamlFile, &GlobalConfig)
fmt.Printf("User: %s\n",GlobalConfig.Database.User)

平时很反感这个，不过受不住低价的诱惑啊。
以前一直用阿里香港轻量一个月的24的机器(2C1G)来做跳板访问国内机器。这罗永浩直播，168一年，2C4G，虽然带宽只有5M，不过我就ssh什么的，5M够了。等于1个月便宜了10块，内存还多了3G，1G装个lnmp都够呛，4G就妥妥的。价格绝对值不多，比例大啊。

在github copilot配合加成下，改得还蛮快的。
sqlx没啥不好，我只不过就想用用gorm，和前些年刚好想反，当时是不用gorm用sqlx。
闲，都是闲出来的。

CPU极其拉跨，也不排除是运行YABS高占用后自动限制了
其它都还可以。其实往往最不重要的就是CPU，运算能力过剩，所以，用起来感觉还好了。
