这篇文章将为大家详细讲解有关如何使用Python将mysql数据导出成json,小编觉得挺实用的,因此分享给大家做个参考,希望大家阅读完这篇文章后可以有所收获。
python有哪些常用库
python常用的库:1.requesuts;2.scrapy;3.pillow;4.twisted;5.numpy;6.matplotlib;7.pygama;8.ipyhton等。
1、相关说明
此脚本可以将Mysql的数据导出成Json格式,导出的内容可以进行select查询确定。
数据传入参数有:dbConfigName, selectSql, jsonPath, fileName。
依赖的库有:MySQLdb、json,尤其MySQLdb需要事先安装好。
2、Python脚本及测试示例
/Users/nisj/PycharmProjects/BiDataProc/oldPythonBak/mysqlData2json.py
# -*- coding=utf-8 -*-
import MySQLdb
import warnings
import datetime
import sys
import json
reload(sys)
sys.setdefaultencoding('utf8')
warnings.filterwarnings("ignore")
mysqlDb_config = {
'host': 'MysqlHostIp',
'user': 'MysqlUser',
'passwd': 'MysqlPass',
'port': 50512,
'db': 'Tv_event'
}
today = datetime.date.today()
yesterday = today - datetime.timedelta(days=1)
tomorrow = today + datetime.timedelta(days=1)
def getDB(dbConfigName):
dbConfig = eval(dbConfigName)
try:
conn = MySQLdb.connect(host=dbConfig['host'], user=dbConfig['user'], passwd=dbConfig['passwd'],
port=dbConfig['port'])
conn.autocommit(True)
curr = conn.cursor()
curr.execute("SET NAMES utf8");
curr.execute("USE %s" % dbConfig['db']);
return conn, curr
except MySQLdb.Error, e:
print "Mysql Error %d: %s" % (e.args[0], e.args[1])
return None, None
def mysql2json(dbConfigName, selectSql, jsonPath, fileName):
conn, curr = getDB(dbConfigName)
curr.execute(selectSql)
datas = curr.fetchall()
fields = curr.description
column_list = []
for field in fields:
column_list.append(field[0])
with open('{jsonPath}{fileName}.json'.format(jsonPath=jsonPath, fileName=fileName), 'w+') as f:
for row in datas:
result = {}
for fieldIndex in range(0, len(column_list)):
result[column_list[fieldIndex]] = str(row[fieldIndex])
jsondata=json.dumps(result, ensure_ascii=False)
f.write(jsondata + '\n')
f.close()
curr.close()
conn.close()
# Batch Test
dbConfigName = 'mysqlDb_config'
selectSql = "SELECT uid,name,phone_num,qq,area,created_time FROM match_apply where match_id = 83 order by created_time desc;"
jsonPath = '/Users/nisj/Desktop/'
fileName = 'mysql2json'
mysql2json(dbConfigName, selectSql, jsonPath, fileName)
