Python连接访问mongodb副本集

代码如下:

from pymongo import MongoClient
 
# 配置副本集的地址
replica_set_hosts = [
    "192.168.10.135:27017",
    "192.168.10.136:27018",
    "192.168.10.137:27019"
]
 
# 创建MongoClient连接
client = MongoClient(replica_set_hosts, username="admin", password="123456", authSource="admin",connecttimeoutms=5,serverSelectionTimeoutMS=5)
 
# 连接到数据库和集合
database = client["test2"]
collection = database["c3"]
 
# 进行查询操作
documents = collection.find({})
for document in documents:
    print(document)

返回结果

{'_id': ObjectId('662d243bb772dcca3598ddf2'), 'uname': 'zs2', 'age': 2.0}
{'_id': ObjectId('662d243bb772dcca3598ddf3'), 'uname': 'zs3', 'age': 3.0}

{'_id': ObjectId('663259d31f00f220c3d2dcd1'), 'uname': 'test01', 'age': 11.0}

补充说明:如果副本集只剩下一个节点是无法访问的
