golang 常用方法

2019/09/15

字符长度要用rune方法

aa := "店舗名（カナ）"
fmt.Println(len([]rune(aa))

切割空字符串长度是一

	storeFields := strings.Split("", ",")
	for i, v := range storeFields {
		if i == 0 && v == "" {
			fmt.Println("空")
		}
		fmt.Println(i, v)
	}

遍历排序数组

	assistArray := make([]string, 0)
	assistArray = append(assistArray, "M000115ALP")
	assistArray = append(assistArray, "M000119UPI")
	assistArray = append(assistArray, "M000115WXP")
	assistArray = append(assistArray, "M000115UPI")

	for i, key := range assistArray {
	fmt.Println(i,key)
	}
	sort.Sort(sort.StringSlice(assistArray))
	for _, key := range assistArray {
		fmt.Println(key)
	}
