利用python如何在前程无忧高效投递简历前言
在前程无忧上投递简历发现有竞争力分析,免费能看到匹配度评价和综合竞争力分数,可以做投递参考
计算方式
综合竞争力得分应该越高越好,匹配度评语也应该评价越高越好
抓取所有职位关键字搜索结果并获取综合竞争力得分和匹配度评语,最后筛选得分评语自动投递合适的简历
登陆获取cookie

from selenium import webdriver from selenium.webdriver.chrome.options import options chrome_options = options() # chrome_options.add_argument('--headless') from time import sleep import re from lxml import etree import requests import os import json driver = webdriver.chrome(chrome_options = chrome_options,executable_path = 'd:\python\chromedriver.exe' ) headers = { "user-agent" : "mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/73.0.3683.86 safari/537.36" } driver.get(https: / / search. 51job .com / list / 020000 , 000000 , 0000 , 00 , 9 , 99 , % 2520 , 2 , 1.html ?lang = c&stype = &postchannel = 0000 &workyear = 99 &cotype = 99 °reefrom = 99 &jobterm = 99 &companysize = 99 &providesalary = 99 &lonlat = 0 % 2c0 &radius = - 1 &ord_field = 0 &confirmdate = 9 &fromtype = &dibiaoid = 0 &address = &line = &specialarea = 00 & from = &welfare = ) |
webdriver需要在相应域名写入cookie,所以转到职位搜索页面
|
def get_cookie(): driver.get( "https://login.51job.com/login.php?loginway=1&lang=c&url=" ) sleep( 2 ) phone = input ( "输入手机号:" ) driver.find_element_by_id( "loginname" ).send_keys(phone) driver.find_element_by_id( "btn7" ).click() sleep( 1 ) code = input ( "输入短信:" ) driver.find_element_by_id( "phonecode" ).send_keys(code) driver.find_element_by_id( "login_btn" ).click() sleep( 2 ) cookies = driver.get_cookies() with open ( "cookie.json" , "w" )as f: f.write(json.dumps(cookies)) |
检查cookie文件是否存在,如果不存在执行get_cookie把cookie写入文件,在登陆的时候最好不用无头模式,偶尔有滑动验证码
前程无忧手机短信一天只能发送三条,保存cookie下次登陆用
|
def get_job(): driver.get( "https://search.51job.com/list/020000,000000,0000,00,9,99,%2520,2,1.html?lang=c&stype=&postchannel=0000&workyear=99&cotype=99°reefrom=99&jobterm=99&companysize=99&providesalary=99&lonlat=0%2c0&radius=-1&ord_field=0&confirmdate=9&fromtype=&dibiaoid=0&address=&line=&specialarea=00&from=&welfare=" ) sleep( 2 ) job = input ( "输入职位:" ) driver.find_element_by_id( "kwdselectid" ).send_keys(job) driver.find_element_by_xpath( '//button[@class="p_but"]' ).click() url = driver.current_url page = driver.page_source return url,page |
在职位搜索获取职位搜索结果,需要返回页面源码和地址
分析页码结构html前的是页码,全部页码数量通过共xx页得到
|
def get_pages(url,page): tree = etree.html(page) href = [] x = tree.xpath( '//span[@class="td"]/text()' )[ 0 ] total_page = int (re.findall( "(\d+)" , x)[ 0 ]) for i in range ( 1 ,total_page + 1 ): href.append(re.sub( "\d.html" , f '{i}.html' , url)) return href |
获取全部页码
|
def get_job_code(url): headers = { "user-agent" : "mozilla/5.0 (windows nt 10.0; win64; x64) applewebkit/537.36 (khtml, like gecko) chrome/73.0.3683.86 safari/537.36" } r = session.get(url,headers = headers) tree = etree.html(r.text) lis = tree.xpath( '//li[@class="el"]/p/span/a/@href' ) job = str (lis) job_id = re.findall( "\/(\d+).html" ,job) return job_id |
获取职位id
修改id请求网址到竞争力分析页面
|
def get_info(job_id): href = f "https://i.51job.com/userset/bounce_window_redirect.php?jobid={job_id}&redirect_type=2" r = session.get(href,headers = headers) r.encoding = r.apparent_encoding tree = etree.html(r.text) pingjia = tree.xpath( '//li[@class="warn w1"]//text()' )[ 0 ].strip() gongsi = [] for i in tree.xpath( '//li[@class="lf"]//text()' ): if i.strip(): gongsi.append(i.strip()) fenshu = [] for i in tree.xpath( '//ul[@class="rt"]//text()' ): if i.strip(): fenshu.append(i.strip()) url = f "https://jobs.51job.com/shanghai/{job_id}.html?s=03&t=0" return { "公司" :gongsi[ 1 ], "职位" :gongsi[ 0 ], "匹配度" :pingjia,fenshu[ 3 ]:fenshu[ 2 ], "链接" :url, "_id" :job_id} |
抓取竞争力分析页面,返回一个字典
主程序
|
if not os.path.exists( "cookie.json" ): get_cookie() f = open ( "cookie.json" , "r" ) cookies = json.loads(f.read()) f.close() |
检查cookie文件载入cookie,不存在执行get_cookie()把cookie保存到文件
|
session = requests.session() for cookie in cookies: driver.add_cookie(cookie) session.cookies. set (cookie[ 'name' ],cookie[ 'value' ]) url, page = get_job() driver.close() |
在session和webdriver写入cookie登陆
获取第一页和url后webdriver就可以关掉了
|
code = [] for i in get_pages(url,page): code = code + get_job_code(i) |
获取的职位id添加到列表
|
import pymongo client = pymongo.mongoclient( "localhost" , 27017 ) db = client[ "job_he" ] job_info = db[ "job_info" ] for i in code: try : if not job_info.find_one({ "_id" :i}): info = get_info(i) sleep( 1 ) job_info.insert_one(info) print (info, "插入成功" ) except : print (code) |
龟速爬取,用mongdb保存结果,职位id作为索引id,插入之前检查id是否存在简单去重减少访问
吃完饭已经抓到8000个职位了,筛选找到127个匹配度好的,开始批量投递
登陆状态点击申请职位,用wevdriver做
|
for i in job_info.find({ "匹配度" :{$regex: "排名很好" }, "综合竞争力得分" :{$gte: "80" }}): print (i) try : driver.get(i) driver.find_element_by_id( "app_ck" ).click() sleep( 2 ) except : pass |
用cookie登陆简单for循环投递,在mongodb里查表,正则筛选匹配度和竞争力得分获取所有匹配结果
投递成功
