python讀取json文件並將數據插入到mongodb的方法

 這篇文章主要介紹了python讀取json文件並將數據插入到mongodb的方法,實例分析了Python操作json及mongodb數據庫的技巧,需要的朋友可以參考下

   

本文實例講述了python讀取json文件並將數據插入到mongodb的方法。分享給大家供大家參考。具體實現方法如下：

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 #coding=utf-8 import sunburnt import urllib from pymongo import Connection from bson.objectid import ObjectId import logging from datetime import datetime import json from time import mktime from feedparser import _parse_date as parse_date import time import sys import getopt import ConfigParser args = sys.argv[1:] optlist, args = getopt.getopt(args, 'c:') cmd_opt = {} for opt in optlist: cmd_opt[opt[0]] = opt[1] conf_file = cmd_opt['-c'] config = ConfigParser.ConfigParser() config.read(conf_file) hostname = config.get("mongodb", "hostname") port_num = int(config.get("mongodb", "port_num")) db_name = config.get("mongodb", "db") connection = Connection(hostname, port_num) db = connection[db_name] courseTable = db.course lecTable = db.lecture try: f = file("json1-14/14.json") s = json.load(f) courseData = s["results"]["course"] lecDataArr = s["results"]["lecture"] f.close print "get file content successfully!" #insert course courseId = courseTable.save(courseData) courseId = str(courseId) print "courseId: "+courseId print "lec length: "+str(len(lecDataArr)) #insert lecture lecIdArr = [] for lecData in lecDataArr: lecData["course_id"] = courseId lecId = lecTable.save(lecData) lecIdArr.append(str(lecId)) # update course courseTable.update({'_id':ObjectId(courseId)}, {"$set":{"lectures.lecture_id_list":lecIdArr}}, upsert=True, multi=True); print 'insert successfully!' except Exception, e: print e

希望本文所述對大家的Python程序設計有所幫助。
