golang: 返回錯誤時列印堆疊

一，預設的錯誤列印:

1,定義函式:

//列印錯誤的堆疊資訊
func PrintStackTrace(err error) {
	// 建立一個緩衝區用於儲存堆疊資訊
	buf := bytes.NewBuffer(nil)

	// 獲取當前goroutine的堆疊資訊
	for i := 0; ; i++ {
		pc, file, line, ok := runtime.Caller(i)
		if !ok {
			break
		}
		fmt.Fprintf(buf, "%d: %s:%d (0x%x)\n", i, file, line, pc)
	}

	// 列印堆疊資訊
	fmt.Println(buf.String())
}

2,呼叫定義的方法

	fields := []string{"id", "addtime","abcd"}

	var rows *sql.Rows
	var err error
	rows,err = config.DBLink.Select(fields).Table(model.PlModel{}.TableName()).Where("uid=? and status=1",uid).Order("id desc").Offset(offset).Limit(size).Rows()

	if err != nil {
		fmt.Println("錯誤資訊:",err)
		fmt.Println("堆疊:")
		config.PrintStackTrace(err)
	}

二，測試效果:
