本文实例讲述了python读取json文件并将数据插入到mongodb的方法。分享给大家供大家参考。具体实现方法如下：

				?

									#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
