原标题：python 爬取boss直聘招聘信息实现

1、一些公共方法的准备

获取数据库链接：

importpymysql

'''

# 获得数据库链接对象

defgetConnect(database):

DATABASE = {

'host': 'localhost',

'database': database,

'user': 'root',

'password': '123456'

}

returnpymysql.connect(**DATABASE)

获取页面soup对象：

importrequests

frombs4 importBeautifulSoup

#转换成soup对象

defto_soup(str):

returnBeautifulSoup(str, 'lxml')

#通过url和header获取页面soup对象

defget_soup(url,header):

response=requests.get(url,headers=header)

returnto_soup(response.text)

2、爬取BOSS直聘python相关岗位的实现

定义工作信息对象：

classWorkInfo:

def__init__(self, title, salary, site, experience, education, job_url, company,release_date,get_date):

self.title = title

self.salary = salary

self.site = site

self.experience = experience

self.education = education

self.job_url = job_url

self.company = company

self.release_date = release_date

self.get_date = get_date

获取工作信息到定义的对象的集合：

# 获取工作信息集合

defgetWorkInfos(url, header):

# 获得页面soup对象

htmlSoup = rep.get_soup(url, header)

workInfos = []

# 获取页面内容块状列表

job_infos = htmlSoup.find_all( 'div', class_= 'job-primary')

iflen(job_infos)== 0:

print( '已到空白页!!!')

returnworkInfos

# 遍历每块，获取每块详细类容

print( '开始爬取页面数据!')

forjob_info_soup injob_infos:

# 标题

title = job_info_soup.find( 'div', class_= 'job-title').get_text

# 薪资

salary = job_info_soup.find( 'span', class_= 'red').get_text

infos = str(job_info_soup.find( 'p'))

infosList = tool.toContent(infos)

# 工作地址

site = infosList[ 0]

# 工作经验

experience = infosList[ 1]

# 学历要求

education = infosList[ 2]

# 详细信息链接

job_url = job_info_soup.find( 'a').get( 'href')

# 公司名

company = job_info_soup.find( 'div', class_= 'company-text').find( 'a').get_text

# 发布时间

release_date = job_info_soup.find( 'div', class_= 'info-publis').find( 'p').get_text[ 3:]

# 拼接获取符合数据库要求的日期字符串

if'昨'inrelease_date:

release_date=time.strftime( "%Y-%m-%d",time.localtime(time.time -86400))

elif':'inrelease_date:

release_date=time.strftime( "%Y-%m-%d")

else:

release_date = str(time.localtime.tm_year) + '-'+ re.sub( r'[月,日]', '-', release_date)[: -1]

# 获取数据的时间

get_date = time.strftime( "%Y-%m-%d %H:%M:%S")

workInfo = WorkInfo(title, salary, site, experience, education, job_url, company, release_date, get_date)

workInfos.append(workInfo)

print( '爬取页面数据完毕！')

returnworkInfos

把获取到的工作信息集合存入数据库：

# 存入数据库

def toDatabase(workInfos):

print('开始存入数据库')

db = database.getConnect('reptile')

cursor = db.cursor

for workInfo in workInfos:

sql = " INSERTINTO`work_info`( `title`, `salary`, `site`, `experience`, `education`, `job_url`, `company`, `release_date`, `get_date`) "

"VALUES( '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s', '%s') "

% (workInfo.title, workInfo.salary, workInfo.site, workInfo.experience, workInfo.education, workInfo.job_url, workInfo.company, workInfo.release_date,workInfo.get_date)

cursor.execute(sql)

cursor.close

db.commit

db.close

print('存入数据库完毕!')

爬取工作实现：
