Python爬Boss,找工作,快人一步!!!

 

 

 

 

按F12,使用开发工具查看下html的结构:

Python爬Boss,找工作,快人一步!!!

 

 

 

 

 

先获取所有的class=”job-primary”的div列表,然后遍历列表对象,在子查询里面的各个需要的信息。

 

 

 

职位需求信息如下:

公司信息:

Python爬Boss,找工作,快人一步!!!

 

 

 

先创建数据库,保存爬取的信息

create table boss_job(
    jid varchar(50) primary key,
    name varchar(50) not null,
    sal varchar(20),
    addr varchar(50),
    work_year varchar(20),
    edu varchar(20),
    company varchar(40),
    company_type varchar(20),
    company_staff varchar(20),
    url varchar(200)
)engine=innodb default charset=utf-8

  

 

boss直聘需要带上cookies,不然无法正常返回,会访问到一个请稍后的页面。

爬取库使用BeautifulSoup4。
