基于多条件的Mongo批量拉取记录

from pymongo import MongoClient

# 连接到MongoDB
client = MongoClient("mongodb://localhost:27017/")
db = client["your_database"]
collection = db["your_collection"]

# 定义查询条件
conditions = [
    {"field1": "value1"},
    {"field2": "value2"},
    {"field3": "value3"}
]

# 构建聚合管道
pipeline = [
    {"$match": {"$or": conditions}},
    # 可以在这里添加更多的聚合操作，例如排序、分组等
]

# 执行聚合查询并获取结果
results = list(collection.aggregate(pipeline))

# 输出结果
for result in results:
    print(result)

pipeline = [
    {"$match": {"$and": [{"field1": "value1"}, {"field2": "value2"}]}}
]
