1. Pymongo安装

pip install pymongo

2. 连接

from pymongo import MongoClient

host = "192.168.92.145"
port = 27017
user_name = "demodb"
user_pwd = "password"
# collection name
db_name = "demo"
coll_name = 'test'

mongo_client = MongoClient(host, port)
db = mongo_client[db_name]
# 认证
db.authenticate(user_name, user_pwd)

# 需要用的的表需要在认证后用client单独去关联
mongo_db = mongo_client[db_name]
mongo_coll = mongo_db[coll_name]

# 获取所有collections并打印，验证是否登录成功
coll_names = mongo_db.list_collection_names(session=None)
print(coll_names)
