简历筛选的python语句 python简历数据提取

爬虫准备

1、先获取薪资和学历、工作经验要求

由于拉勾网数据加载是动态加载的，需要我们分析。分析方法如下：

F12分析页面数据存储位置

我们发现网页内容是通过post请求得到的，返回数据是json格式，那我们直接拿到json数据即可。

我们只需要薪资和学历、工作经验还有单个招聘信息，返回json数据字典中对应的英文为：positionId,salary, education, workYear(positionId为单个招聘信息详情页面编号)。相关操作代码如下：

根据获取到的positionId来访问招聘信息详细页面根据positionId还原访问链接：

position_url = []
def read_csv():
# 读取文件内容
with open(r'G:\lagou_anv.csv', 'r', newline='') as file_test:
# 读文件
reader = csv.reader(file_test)
i = 0
for row in reader:
if i != 0 :
# 根据positionID补全链接
url_single = "https://www.lagou.com/jobs/%s.html"%row[0]
position_url.append(url_single)
i = i + 1
print('一共有：'+str(i-1)+'个')
print(position_url)访问招聘信息详情页面，获取职位描述(岗位职责和岗位要求)并清理数据：
def get_info():
for position_url in position_urls:
work_duty = ''
work_requirement = ''
response00 = get_response(position_url,headers = headers)
time.sleep(1)
content = response00.xpath('//*[@id="job_detail"]/dd[2]/div/p/text()')
# 数据清理
j = 0
for i in range(len(content)):
content[i] = content[i].replace('\xa0',' ')
if content[i][0].isdigit():
if j == 0:
content[i] = content[i][2:].replace('、',' ')
content[i] = re.sub('[；;.0-9。]','', content[i])
work_duty = work_duty+content[i]+ '/'
j = j + 1
elif content[i][0] == '1' and not content[i][1].isdigit():
break
else:
content[i] = content[i][2:].replace('、', ' ')
content[i] = re.sub('[、；;.0-9。]','',content[i])
work_duty = work_duty + content[i]+ '/'
m = i
# 岗位职责
write_file(work_duty)
print(work_duty)
# 数据清理
j = 0
for i in range(m,len(content)):
content[i] = content[i].replace('\xa0',' ')
if content[i][0].isdigit():
if j == 0:
content[i] = content[i][2:].replace('、', ' ')
content[i] = re.sub('[、；;.0-9。]', '', content[i])
work_requirement = work_requirement + content[i] + '/'
j = j + 1
elif content[i][0] == '1' and not content[i][1].isdigit():
# 控制范围
break
else:
content[i] = content[i][2:].replace('、', ' ')
content[i] = re.sub('[、；;.0-9。]', '', content[i])
work_requirement = work_requirement + content[i] + '/'
# 岗位要求
write_file2(work_requirement)
print(work_requirement)
print("-----------------------------")
