使用Python从MongoDB文件中检索最近n天

import pymongo
from datetime import datetime, timedelta

client = pymongo.MongoClient("mongodb://localhost:27017/")  # 连接本地MongoDB服务器
db = client["your_database_name"]  # 替换为实际的数据库名
collection = db["your_collection_name"]  # 替换为实际的集合名

n = 7  # 替换为实际需要的天数
end_date = datetime.now()  # 当前日期
start_date = end_date - timedelta(days=n)  # 计算开始日期

query = {"timestamp": {"$gte": start_date, "$lte": end_date}}
results = collection.find(query)

for result in results:
    # 处理每条结果数据
    print(result)
