解决pymongo里操作IOSDate类型的问题

pymongo是Python对MongoDB的操作库。但是由于python没有IOSDate类型，所以对Mongo的时间类型是个很麻烦的操作。整理一个把python能识别的date类型转化为IOSDate类型

脚本如下：
#!/usr/bin/python
import pymongo
from dateutil import parser
dateStr = '2018-06-12T00:00:00.000Z'
myDatetime = parser.parse(dateStr)
client = pymongo.MongoClient(host="192.168.2.14",port=29019)
db = client.dbs
db.authenticate()
db.ceshi.insert({'date': myDatetime})

到MongoDB里查看数据：

testin.dbs>db.ceshi.find()
　　{ "_id" : ObjectId("5b3054fa29e93634dcc21645"), "date" : ISODate("2018-06-12T00:00:00Z") }

已经插入ISODate格式时间。

pymongo查询数据实操：

import pymongo,datetime
from dateutil import parser
def findmongo():
    time1 = datetime.datetime.now()

    dateStr1 = '2019-01-21T00:00:00Z'
    dateStr2 = '2019-01-23T00:00:00Z'
    myDatetime1 = parser.parse(dateStr1)
    myDatetime2 = parser.parse(dateStr2)

    client = pymongo.MongoClient(host="0.0.0.0", port=3717)
    db = client.mongolilly
    db.authenticate("root","admin")

    a = db.current_temp.find({"order_id":"465","scan_time":{ "$gte": myDatetime1, "$lte":myDatetime2}})
    time2 = datetime.datetime.now()
    time3 = time2 - time1
    print "time3------->select_time :%s" % time3

    list = []
    for i in a :
        data = {
            "number": i["number"],
            "temperature": i["temperature"],
            "scan_time": i["scan_time"],
            "scan_location": i["scan_location"],
            "battery": i["battery"],
            "rssi": i["rssi"],
            "mac": i["mac"],
            "order_id": i["order_id"]
            # "id": str(one_info.id)
        }
        list.append(data)

    time4 = datetime.datetime.now()
    time5 = time4-time1
    print "time5------>all_time:",time5
