如何获取刚刚插入到MongoDB中的文档的ID？(API)

from pymongo import MongoClient

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

# 插入文档
collection = db['mycollection']
document = {"name": "John", "age": 30}
result = collection.insert_one(document)

# 获取插入文档的ID
document_id = result.inserted_id
print("插入的文档ID为:", document_id)

from pymongo import MongoClient

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

# 插入多个文档
collection = db['mycollection']
documents = [{"name": "John", "age": 30}, {"name": "Alice", "age": 25}]
result = collection.insert_many(documents)

# 获取插入文档的ID列表
document_ids = result.inserted_ids
print("插入的文档ID列表为:", document_ids)
