做开发中难免时间类型之间的转换， 最近就发现前端js和后端django经常要用到这个转换， 其中jsDate.now()精确到毫秒，而Python中Datetime.datetime.now()是精确到微秒的。
1. 字符串日期时间转换成时间戳
# '2015-08-28 16:43:37.283' --> 1440751417.283
# 或者 '2015-08-28 16:43:37' --> 1440751417.0
def string2timestamp(strValue):
try:
d = datetime.datetime.strptime(strValue, "%Y-%m-%d %H:%M:%S.%f")
t = d.timetuple()
timeStamp = int(time.mktime(t))
timeStamp = float(str(timeStamp) + str("%06d" % d.microsecond))/1000000
print timeStamp
return timeStamp
except ValueError as e:
print e
d = datetime.datetime.strptime(str2, "%Y-%m-%d %H:%M:%S")
t = d.timetuple()
timeStamp = int(time.mktime(t))
timeStamp = float(str(timeStamp) + str("%06d" % d.microsecond))/1000000
print timeStamp
return timeStamp
2. 时间戳转换成字符串日期时间
# 1440751417.283 --> '2015-08-28 16:43:37.283'
def timestamp2string(timeStamp):
try:
d = datetime.datetime.fromtimestamp(timeStamp)
str1 = d.strftime("%Y-%m-%d %H:%M:%S.%f")
# 2015-08-28 16:43:37.283000'
return str1
except Exception as e:
print e
return ''
