使用Python将JSON插入MySQL

Question

我在Python中有一个JSON对象。我正在使用Python DB-API和SimpleJson。我正在尝试将json插入MySQL表中。

目前出现错误，我相信这是由于JSON对象中的单引号引起的。

如何使用Python将JSON对象插入MySQL？

这是我收到的错误消息：

另一个错误供参考

#!/usr/bin/env python

try:
        import json as simplejson
except ImportError:
        import simplejson

import twitstream
import MySQLdb

USER = ''
PASS = ''

USAGE = """%prog"""


conn = MySQLdb.connect(host = "",
                       user = "",
                       passwd = "",
                       db = "")

# Define a function/callable to be called on every status:
def callback(status):

    twitdb = conn.cursor ()
    twitdb.execute ("INSERT INTO tweets_unprocessed (text, created_at, twitter_id, user_id, user_screen_name, json) VALUES (%s,%s,%s,%s,%s,%s)",(status.get('text'), status.get('created_at'), status.get('id'), status.get('user', {}).get('id'), status.get('user', {}).get('screen_name'), status))

   # print status
     #print "%s:\t%s\n" % (status.get('user', {}).get('screen_name'), status.get('text'))

if __name__ == '__main__':
    # Call a specific API method from the twitstream module:
    # stream = twitstream.spritzer(USER, PASS, callback)

    twitstream.parser.usage = USAGE
    (options, args) = twitstream.parser.parse_args()

    if len(args) < 1:
        args = ['Blackberry']

    stream = twitstream.track(USER, PASS, callback, args, options.debug, engine=options.engine)

    # Loop forever on the streaming call:
    stream.run()

使用json.dumps（json_value）在json字符串中转换json对象（python对象），您可以在mysql的文本字段中插入
