将字符串转换为pymongo中的日期

from datetime import datetime
from pymongo import MongoClient

# 假设字符串日期为'2022-01-01'
date_str = '2022-01-01'

# 将字符串解析为datetime对象
date_obj = datetime.strptime(date_str, '%Y-%m-%d')

# 将datetime对象转换为pymongo的日期格式
pymongo_date = {
    '$date': {
        '$numberLong': str(int(date_obj.timestamp() * 1000))
    }
}

# 连接MongoDB数据库
client = MongoClient('mongodb://localhost:27017')
db = client['your_database']

# 插入包含日期的文档
db['your_collection'].insert_one({
    'date': pymongo_date
})
