Python中如何使用mongodb模块

这篇文章给大家介绍Python中如何使用mongodb模块，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。

涉及到python和mongodb，那么安装相应的模块四必不可少的，最简单的安装方法，或者非pip不可了。

# pip install pymongo==3.0.4

顺便也记录下源码安装的方式

# wget https://pypi.python.org/packages/source/p/pymongo/pymongo-2.8.tar.gz#md5=23100361c9af1904eb2d7722f2658114 --no-check-certificate# tar xf pymongo-2.8.tar.gz# cd pymongo-2.8# python setup.py install

入库mongodb的python脚本

[root@localhost opt]# cat analytical.py #!/usr/bin/env python#coding:utf8import os,sys,jsonfrom datetime import * from pymongo import MongoClientdef ConMongo(host,port,cur_db,username,password):    client = MongoClient(host,port)    db = client[cur_db]    db.authenticate(username,password)    table = db.gamelogs    return tabledef parseLog(logfile,table):    dic = {}    dl = []    with open(file_log) as fd:        for line in fd:            try:                tokens = line.strip().split('\t')                uid = tokens[0]                server = tokens[1]                system = tokens[2]                level = int(tokens[3])                vip_level = tokens[4]                ip = tokens[5]                time = datetime.strptime(tokens[6], "%Y-%m-%d %H:%M:%S")          #将时间字符串转换成时间格式                action = tokens[7]                result = json.loads(tokens[8])                                                #特殊字符串转换成json格式                uuid = tokens[9]                if len(tokens) == 12:                channel = tokens[11]                else:                    channel = ''                dic = {'uid':uid,'server':server,'system':system,'level':level,'vip_level':vip_level,'ip':ip,'time':time,'action':action,'result':result,'uuid':uuid,'channel':channel}                dl.append(dic)                if len(dl) == 10000:                    table.insert_many(dl)                    dl = []            except Exception,e:                    print e, line        if len(dl) > 0:            table.insert_many(dl)if __name__ == '__main__':    table = ConMongo('localhost',27017,'talefundb','talefun','123456')    try:            logfile = sys.argv[1]        parseLog(logfile,table)    except IndexError,e:            print e

注意事项：

(1)insert_many参数是mongodb 3.0.4中新加的，允许你将一个大列表直接insert到mongodb数据库中(2)脚本中做了限制，如果字典中有2000个值，就向mongodb插入一次数据，这样在效率上得到了保证(3)不建议直接复制脚本测试，很多粘贴出来后，很多制表符等会出现问题。我会吧脚本放在云盘上大家可以下载，测试用。
