用户名、密码 连接mongodb数据库

    最近遇到服务器迁移，增加了mongodb的权限认证，所以导致之前的程序不能正确的执行，特意查看了相应的api
1. java连接mongodb
    MongoClient mongoClient;
    MongoCredential credential = MongoCredential.createCredential("user", "database", password);
    mongoClient = new MongoClient(new ServerAddress(ip, port), Arrays.asList(credential));
2. python连接mongodb
   from pymongo import MongoClient
    
    client = MongoClient("ip",port)
    client.database.authenticate("user","password")
    db = client.database
    collection = db.collection
