        前文中我们把网络爬虫爬取的数据保存为JSON格式,但为了能够更方便地处理数据,我们希望把这些数据导入到MySQL数据库中。phpMyadmin可以把MySQL数据库中的数据导出为JSON格式文件,但却不能把JSON格式文件导入到MySQL数据库。为了实现这个目标,可以编写Python脚本将JSON格式数据转换为SQL语句以便导入MySQL数据库。

JSON文件tencent.json部分内容:

{"recruitNumber": "1", "name": "SD10-FPS俄语游戏海外PM(深圳)", "detailLink": "http://hr.tencent.com/position_detail.php?id=9587&keywords=&tid=0&lid=0", "publishTime": "2013-11-13", "catalog": "产品/项目类", "workLocation": "深圳"}
{"recruitNumber": "2", "name": "HY2-互动娱乐游戏网游财产安全运营专员(深圳)", "detailLink": "http://hr.tencent.com/position_detail.php?id=9482&keywords=&tid=0&lid=0", "publishTime": "2013-11-28", "catalog": "产品/项目类", "workLocation": "深圳"}

在phpMyadmin中创建数据库及表结构:

CREATE DATABASE itzhaopin;
Copy after login
CREATE TABLE IF NOT EXISTS `tencent` (`id` int(11) NOT NULL auto_increment,`name` varchar(512)default NULL,`catalog` varchar(64) default NULL,`workLocation` varchar(64) default NULL,`recruitNumber` varchar(64) default NULL,`detailLink` varchar(1024) default NULL,`publishTime` varchar(64) default NULL,PRIMARY KEY (`ID`)) ENGINE=MyISAMDEFAULT CHARSET=utf8 AUTO_INCREMENT=1;
Copy after login
编写Python脚本json2sql.py将JSON格式数据转换为SQL语句:
#-*- coding: UTF-8 -*-import jsondata = []with open('itzhaopin/tencent.json') as f:	for line in f:		data.append(json.loads(line))#print json.dumps(data, ensure_ascii=False)str = "/r/n"for item in data:	#print json.dumps(item)	str = str + "insert into tencent(name,catalog,workLocation,recruitNumber,detailLink,publishTime) values "	str = str + "('%s','%s','%s','%s','%s','%s');/r/n" % (item['name'],item['catalog'],item['workLocation'],item['recruitNumber'],item['detailLink'],item['publishTime'])import codecsfile_object = codecs.open('tencent.sql', 'w' ,"utf-8")file_object.write(str)file_object.close()print "success"
Copy after login

执行该python脚本,在当前目录下将生成一个名为tencent.sql的文件,在phpMyadmin中导入并执行该文件,爬虫抓取的数据将导入MySQL数据库。
