https://api.mongodb.com/

 

2、github

4、安装

pip install pymongo

 

5、封装

from pymongo import MongoClient


class MongoConnectClient(object):
    def __init__(self, db, collect_name, uri='mongodb://localhost:27017/'):
        self.uri = uri
        # self.client = MongoClient(self.host, self.port)
        self.client = MongoClient(self.uri)
        self.db = self.client.get_database(db)
        self.col = self.db.get_collection(collect_name)

    def close(self):
        self.client.close()

    def find_many(self, condition=None):
        if not condition:
            condition = {}
        cursor_obj = self.col.find(condition)
        result = [data for data in cursor_obj]
        return result

    def insert_one(self, data):
        return self.col.insert_one(data).inserted_id

    def insert_many(self, data_list):
        return self.col.insert_many(data_list).inserted_ids

    def update_many(self, condition, new_values):
        if not condition:
            raise Exception("condition is None")
        return self.col.update_many(condition, new_values).raw_result

    def delete_many(self, condition):
        if not condition:
            raise Exception("condition is None")
        return self.col.delete_many(condition).raw_result


if __name__ == '__main__':
    mc = MongoConnectClient("test", "user")
    print(mc.db.list_collection_names())
