获取查询 参数
def getFidByDate(fid):
yesterDate = getDatetimeYesterday()
params="from="+yesterDate +"&to="+yesterDate +"&fid="+str(fid)
url=monitorUrl+params
u=urllib2.urlopen(url)
jsonData=json.loads(u.read().decode('utf-8'))
return jsonData["result"]
得到今天日期
def getDatetimeToday():
t = date.today() #date类型
dt = datetime.strptime(str(t),'%Y-%m-%d') #date转str再转datetime
return dt
得到昨天日期
def getDatetimeYesterday():
today = getDatetimeToday() # datetime类型当前日期
yesterday = today + timedelta(days=-1) # 减去一天
return str(yesterday).split()[0]
得到前天日期
def getDatetimeQianTian():
today = getDatetimeToday() # datetime类型当前日期
qt = today + timedelta(days=-2) # 减去一天
return str(qt).split()[0]

引入 datetime 模块
import datetime
def getYesterday():
today=datetime.date.today()
oneday=datetime.timedelta(days=1)
yesterday=today-oneday
return yesterday
输出
print(getYesterday())
日期和字符串互转
把datetime转成字符串
def datetime_toString(dt):
return dt.strftime("%Y-%m-%d-%H")
把字符串转成datetime
def string_toDatetime(string):
return datetime.strptime(string, "%Y-%m-%d-%H")
把字符串转成时间戳形式
def string_toTimestamp(strTime):
return time.mktime(string_toDatetime(strTime).timetuple())
把时间戳转成字符串形式
def timestamp_toString(stamp):
return time.strftime("%Y-%m-%d-%H", tiem.localtime(stamp))
把datetime类型转外时间戳形式
def datetime_toTimestamp(dateTim):
return time.mktime(dateTim.timetuple())
