insert_one()返回InsertOneResult的一个实例。有关"_id“的更多信息，请参见id。
startup事件用来初始化 MongoDB 客户端并建立连接,而shutdown事件则用来安全地关闭连接。 MongoDB.py 接下来,我们来定义mongodb.py文件中的 MongoDB 交互操作。 from typing import List, Dict, Any, Mapping from fastapi import HTTPException from bson import ObjectId from motor.motor_asyncio import AsyncIOMot...
