1、相關說明

此指令碼可以將Mysql的資料匯出成Json格式，匯出的內容可以進行select查詢確定。

資料傳入引數有：dbConfigName,selectSql,jsonPath,fileName。

依賴的庫有：MySQLdb、json，尤其MySQLdb需要事先安裝好。

2、Python指令碼及測試示例

/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,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,fileName)

以上這篇用Python將mysql資料匯出成json的方法就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支援我們。
