最简单的易班打卡脚本
易班web自动化打卡脚本分析实现过程环境搭建定位元素获取cookies使用cookies定时启动脚本完整代码易班web自动化打卡脚本
一直以来，易班打卡被称为最鸡肋，最浪费时间，最浪费纳税人钱财的表面工程，那么如何解决这一问题，已成为现在高校大学生的急需思考的大问题。那这一次我就来谈谈我是怎么解决这一问题的。
分析
众所周知，学生虽然使用较多的是易班APP，但是，善良的易班还做了网页端。刚好前不久我学习了一点儿web自动化技术，正好拿来练练手。
先来看看易班的登录界面，它使用了验证码，然而，图形验证码就是专门克制机器操作的，所以验证码只能使用人为识别。那该如何实现自动登录呢？
我们发现，登录一次之后，再次打开页面就会自动登录，原来易班记录了用户的cookies。
没错，你猜对了！我就是保存cookies，每次登录都更换cookies，以实现多用户登录打卡。
实现过程
环境搭建
网上有很多webdriver环境搭建的教程，我就不再啰嗦了
定位元素
使用google浏览器复制的full xpath
driver.find_element_by_xpath("/html/body/div1/div/div[2]/div1").click()
通过full xpath查找网页元素，并且执行点击操作；
driver.find_element_by_id(“account-txt”).send_keys("*****")
通过id查找网页元素，并且执行输入操作；
会用这两个方法就够了（这也太low了）
获取cookies
一段非常简单的代码，跑跑看
import selenium.webdriverimport timeimport jsonlst[] = ["",""] # 分别填上账号和密码driver = selenium.webdriver.Chrome()driver.implicitly_wait(10)driver.get("/")driver.delete_all_cookies() # 删除已有cookiesprint("登录过程需要手动输入验证码")time.sleep(1)driver.get("/login?go=http%3A%2F%%2F") # 进入登录界面driver.find_element_by_id("account-txt").send_keys(lst[0])driver.find_element_by_id("password-txt").send_keys(lst[1])driver.find_element_by_id("login-btn").click()print("登录过程可能需要手动输入验证码\n完成登录后，键入y，开始提取用户cookies\n无法登录情况下，键入n或其他任意字符，跳过此次提取")dd = input("是否完成登录?(y/n)")if(dd == 'y'):cookies = driver.get_cookies()print("已获取cookies")jsoncookies = json.dumps(cookies)# 将cookies保存到cookies.txt中with open("cookies.txt", "a+")as f:ss = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time()))f.write("\n"+ss+"#"+str(lst[0])+"#"+str(lst[1])+"#"+"cookies--->"+jsoncookies)print("cookies已添加在cookies.txt！")else:print("未提取cookies，并跳过此用户")driver.quit()
使用cookies
import selenium.webdriverimport timeimport jsondriver = selenium.webdriver.Chrome()driver.get("/")driver.implicitly_wait(8)time.sleep(2)line = input("请输入cookies:")cookies = json.loads(line)driver.delete_all_cookies()driver.get("/")for co in cookies:driver.add_cookie(co)driver.get("/iapp659175")
定时启动脚本
假设看到这的小伙伴已经写好了完整代码，现在开始用服务器定时启动打卡脚本
crontab -e
3 6,11,17 * * * /usr/bin/python /home/yiban/yibandaka.py >> /www/wwwroot/mblog.ren/submit/yiban/run_log.txt 2>&1
每天的6点、11点、17点的03分开始执行脚本，并将记录保存在run_log.txt
完整代码
代码写的比较随意，将就一下吧！
下面代码是直接从服务器拷贝过来的，用电脑的话，需要稍作修改
