Golang 和Python 几个小时前 几分钟 几天前的处理

在用golang爬虫的时候

总会遇到 10天前 10分钟前 刚刚这种很影响我们爬取正常事件

所以我写了个方法 来格式化这种事件

golang 版本

package utils

import (
	"fmt"
	"regexp"
	"strconv"
	"strings"
	"time"
)

func HoursBeforeDayBeforeFormat(arcTime string) string {
	arcTime = strings.TrimSpace(arcTime)

	timeList := [...]string{
		"小时前",
		"分钟前",
		"刚刚",
	}

	t := time.Now()                                // 获取当前时间
	currentTime := t.Format("2006-01-02 15:04:05") //获取当前格式的日期
	for _, _value := range timeList {
		isContains := strings.Contains(arcTime, _value)
		if isContains {
			nowHour := time.Now().Format("15")
			pattern := regexp.MustCompile(`\d+`)
			afterNumber := pattern.FindString(arcTime)
			if afterNumber == "" {
				if arcTime == "刚刚" {
					return currentTime
				} else {
					return "请传入带有数字类型 比如：5小时前"
				}
			}

			if afterNumber <= nowHour {
				return currentTime
			} else if strings.Contains(arcTime, "分钟前") {
				return currentTime
			} else {
				beforeDay := t.AddDate(0, 0, -1)
				return beforeDay.Format("2006-01-02 15:04:05")
			}
		}
	}

	if strings.Contains(arcTime, "天前") {
		pattern := regexp.MustCompile(`\d+`)
		afterNumber, err := strconv.Atoi(fmt.Sprint("-", pattern.FindString(arcTime)))
		if err != nil {
			return fmt.Sprintln(arcTime, "正则提取错误")
		}

		return fmt.Sprintln(t.AddDate(0, 0, afterNumber).Format("2006-01-02 15:04:05"))
	} else {
		return arcTime
	}

}
