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 webdriverfrom selenium.webdriver.chrome.options import Optionschrome_options = Options()# chrome_options.add_argument('--headless')from time import sleepimport refrom lxml import etreeimport requestsimport osimport jsondriver = 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&degreefrom=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&degreefrom=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) divs=tree.xpath('//div[@class="el"]/p/span/a/@href') job=str(divs) 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('//div[@class="warn w1"]//text()')[0].strip() gongsi=[] for i in tree.xpath('//div[@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 pymongoclient=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
