使用pymongo向现有副本集中添加新成员？

import pymongo
from pymongo import MongoClient

client = MongoClient('mongodb://<hostname>:<port>/')

new_member = {
    "_id": <member_id>,
    "host": "<hostname>:<port>"
}

admin_db = client.admin

admin_db.authenticate("<username>", "<password>")

admin_db.command("replSetAdd", "rs0", members=[new_member])

import pymongo
from pymongo import MongoClient

# 创建MongoDB的连接客户端
client = MongoClient('mongodb://<hostname>:<port>/')

# 获取要添加的新成员的配置信息
new_member = {
    "_id": <member_id>,
    "host": "<hostname>:<port>"
}

# 获取副本集的管理对象
admin_db = client.admin

# 使用管理员凭证进行身份验证
admin_db.authenticate("<username>", "<password>")

# 向副本集中添加新成员
admin_db.command("replSetAdd", "rs0", members=[new_member])
