python爬取51job职位并写入mysql

只获取公司、职位、地区、薪水，没有其他详细的信息，所以代码很简单。体验体验python和mysql的交互，刚开始插进去的数据都是乱码，在连接mysql的时候指定utf8编码就解决了。

# -*- coding:utf-8 -*-
import requests
import re,pymysql

def get_content(page):
    url ='http://search.51job.com/list/000000,000000,0000,00,9,99,%25E6%2595%25B0%25E6%258D%25AE%25E5%2588%2586%25E6%259E%2590,2,'+ str(page)+'.html'
    html=requests.get(url)
    s = requests.session()
    s.keep_alive = False
    html.encoding='gbk'
    return html

def get(html):
    reg = re.compile(r'class="t1 ">.*? (.*?).*?(.*?).*? (.*?)',re.S)#匹配换行符
    items = re.findall(reg,html.text)
    return items
def savetosql(items):
    print('正在连接到服务器')
    db=pymysql.connect('localhost','root','123456','justtest', charset="utf8")
    print('连接成功')
    cursor=db.cursor()
    cursor.execute('DROP TABLE IF EXISTS JOBS')
    SQL='''CREATE TABLE JOBS( 
        POSITION TEXT(1000) NOT NULL,
        COMPANY TEXT(1000),
        ADDRESS TEXT(1000),
        SALARY TEXT(1000),
        DATE TEXT(1000))'''
    cursor.execute(SQL)
    print('创建成功')
    for item in items:
        sql="insert into JOBS values('%s','%s','%s','%s','%s')"%(item[0],item[1],item[2],item[3],item[4])
        print(item[1])
        try:
            cursor.execute(sql)
            db.commit()
        except:
            print('插入失败')
            db.rollback()
for page in range(1,20):
    print('正在爬取第{}页'.format(page))
    savetosql(get(get_content(page)))
