爬虫----51job信息爬取

直接上代码

import pandas as pd
import matplotlib.pyplot as plt
from selenium.webdriver import Chrome
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
import time
import csv

url = r'https://login.51job.com/login.php?lang=c'
# 处理反selenium： window.navigator.webdriver
opt = Options()
opt.add_argument('--disable-blink-features=AutomationControlled')

web.get(url)


# 处理登录
switch_pw_login = web.find_element(By.XPATH, '//*[@id="NormalLoginBtn"]/span[3]/a').click()
time.sleep(1)

# user_input 和pw_input分别是用户和密码
user_input = web.find_element(By.XPATH, '//*[@id="loginname"]').send_keys('你的用户账号')
pw_input = web.find_element(By.XPATH, '//*[@id="password"]').send_keys('你的密码')

time.sleep(1)

time.sleep(5)
#  注意在这一步的时候，51job可能会跳出来验证信息，我让程序睡5秒，可以手动再页面上拉那个验证进度条，程序就会往下走了



# 爬取信息
web.maximize_window()

# 输入关键字符然后搜索  python 可以换成任意你想搜的工作信息
web.find_element(By.XPATH, '//*[@id="kwd"]').send_keys('python')
web.find_element(By.XPATH, '//*[@id="topIndex"]/div/div/i').click()

# 信息获取
time.sleep(5)

f = open('res.csv','a',newline='')
csvwriter = csv.writer(f)
while 1:
    job_info = web.find_element(By.XPATH, '/html/body/div[2]/div[3]/div/div[2]/div[4]/div[1]').find_elements(By.CLASS_NAME,'e')
    # print(job_info)
    for job in job_info:
        try:
            job_name = job.find_element(By.XPATH, './/p[@class="t"]/span[1]').text
            money = job.find_element(By.CLASS_NAME, 'sal').text
            time_update = job.find_element(By.XPATH, './/p[@class="t"]/span[2]').text
            info = job.find_element(By.XPATH, './/p[@class="info"]/span[2]').text
            print(job_name, money, time_update, info)
            csvwriter.writerow([job_name, money, time_update, info])
        except Exception as e:
            print(e)
    web.find_element(By.CLASS_NAME,'j_page').find_element(By.CLASS_NAME, 'e_icons').click()
    time.sleep(1)
f.close()
web.close()

结果展示

还在继续爬，已经爬了16000多条信息，静静等着51job把我ip给屏蔽了。。。。。

程序处理的不美观，能用就行，别介意，哈哈哈。
