时间转换和密码,手机的re模块简单校验

import re,time

def check_userinfo(request):
    pwd = request.POST.get("pwd")
    if "_" in pwd or re.findall("\W",pwd):
        return False,"pwd must be number or alpha"
    tel = request.POST.get("tel")
    if len(tel) != 11:
        return False,"telephone number must be 11"
    try:
        #手机号码简单校验
        res = re.search("^13\d{9}$",tel).group()
    except AttributeError:
        return False,"illegal telephone"
    except ValueError:
        return False,"telephone must be number"
    combo_pk = request.POST.get("combo_pk")
    combo_obj = Combo.objects.filter(pk=combo_pk)
    if not combo_obj:
        return False,"combo not exists"
    #前台传回的格式化的字符串时间"2019-4-20"
    consum_time = request.POST.get("consum_time")

    #先转换为结构化的时间struct_time(tm_year=2019, tm_mon=4, tm_mday=20, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=5, tm_yday=110, tm_isdst=-1)
    struct_time = time.strptime(consum_time, '%Y-%m-%d')
    
    #再转化为时间戳进行比对
    old_time = time.mktime(struct_time)

    if time.time() < time.mktime(struct_time):
        return False,"time error,bigger than current time"
    return True,(pwd,tel,combo_pk,consum_time)

django模块的时区设置

TIME_ZONE = 'Asia/Shanghai'

USE_TZ = False

在设置了USE_TZ=True之后，如果设置了TIME_ZONE = 'Asia/Shanghai'，尽管数据库中存储的是UTC时间，但在模板显示的时候，会转成TIME_ZONE所示的本地时间进行显示。
