Python 操作mongodb 簡單實例

　　1、建立數據庫用戶

　　　　要讀寫 mongo數據庫，默認沒有用戶名和密碼也可以對數據庫進行讀寫操作，但是從安全的角度，最好給要操作的數據庫建立用戶名和密碼。

　　　　打開mongo數據庫服務，打開mongo.exe,建立用戶

　　　　具體的用戶權限參照：http://www.cnblogs.com/shaosks/p/6589867.html

　　　　注意：下面的創建用戶的角色是：dbOwner，按說讀寫數據庫用戶權限用readWrite就可以了，但是好像用readWrite，在用程序驗證的報錯，沒有辦法就用了dbOwner角色

 use admin
switched to db admin
> db.auth("myUserAdmin","mypass123")
1
> use OTT_DB
switched to db OTT_DB
> db.createUser(
... ... ... ...  {
... ... ... ...     user: "ott_test",
... ... ... ...    pwd: "ott_test",
... ... ... ...     roles: [
... ... ... ...       { role: "dbOwner", db: "OTT_DB" },
... ... ... ...    ]
... ... ... ...  }
... ... ... ...  )
Successfully added user: {
        "user" : "ott_test",
        "roles" : [
                {
                        "role" : "dbOwner",
                        "db" : "OTT_DB"
                }
        ]
}
> db.auth("ott_test","ott_test")
1
> db.test.insert({name:"mike"})
WriteResult({ "nInserted" : 1 })
>

 

　　2、訪問代碼

# coding=utf-8
from pymongo import ASCENDING, DESCENDING
from pymongo import MongoClient
import codecs
import time
import os
import datetime
from pyExcelerator import *
import csv
class mongoDbBase:

    def __init__(self, databaseIp = '127.0.0.1',databasePort = 27017,user = "ott",password= "ott", mongodbName='OTT_DB'):

        client = MongoClient(databaseIp,databasePort)
        self.db = client[mongodbName]
        self.db.authenticate(user,password)

    def saveTestInfo(self):
        dict = {"name":"大山"}
        self.db.test.insert(dict)



obj = mongoDbBase()
obj.saveTestInfo()
