易班web自動化打卡指令碼

一直以來,易班打卡被稱為最雞肋,最浪費時間,最浪費納稅人錢財的表面工程,那麼如何解決這一問題,已成為現在高校大學生的急需思考的大問題。那這一次我就來談談我是怎麼解決這一問題的。

分析

眾所周知,學生雖然使用較多的是易班APP,但是,善良的易班還做了網頁端。剛好前不久我學習了一點兒web自動化技術,正好拿來練練手。 先來看看易班的登入介面,它使用了驗證碼,然而,圖形驗證碼就是專門剋制機器操作的,所以驗證碼只能使用人為識別。那該如何實現自動登入呢?

我們發現,登入一次之後,再次開啟頁面就會自動登入,原來易班記錄了使用者的cookies。 沒錯,你猜對了!我就是儲存cookies,每次登入都更換cookies,以實現多使用者登入打卡。

實現過程環境搭建

網上有很多webdriver環境搭建的教程,我就不再囉嗦了

定位元素

使用google瀏覽器複製的full xpath driver.find_element_by_xpath("/html/body/div1/div/div[2]/div1").click() 透過full xpath查詢網頁元素,並且執行點選操作;

driver.find_element_by_id(“account-txt”).send_keys("*****") 透過id查詢網頁元素,並且執行輸入操作;

會用這兩個方法就夠了(這也太low了)

獲取cookies

一段非常簡單的程式碼,跑跑看

import selenium.webdriverimport timeimport jsonlst[] = ["",""] # 分別填上賬號和密碼driver = selenium.webdriver.Chrome()driver.implicitly_wait(10)driver.get("http://www.yiban.cn/")driver.delete_all_cookies() # 刪除已有cookiesprint("登入過程需要手動輸入驗證碼")time.sleep(1)driver.get("https://www.yiban.cn/login?go=http%3A%2F%2Fwww.yiban.cn%2F") # 進入登入介面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("登入過程可能需要手動輸入驗證碼\n完成登入後,鍵入y,開始提取使用者cookies\n無法登入情況下,鍵入n或其他任意字元,跳過此次提取")dd = input("是否完成登入?(y/n)")if(dd == 'y'):    cookies = driver.get_cookies()    print("已獲取cookies")    jsoncookies = json.dumps(cookies)    # 將cookies儲存到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已新增在cookies.txt!")else:    print("未提取cookies,並跳過此使用者")driver.quit()
定時啟動指令碼

假設看到這的小夥伴已經寫好了完整程式碼,現在開始用伺服器定時啟動打卡指令碼 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點、11點、17點的03分開始執行指令碼,並將記錄儲存在run_log.txt

完整程式碼

程式碼寫的比較隨意,將就一下吧! 下面程式碼是直接從伺服器複製過來的,用電腦的話,需要稍作修改
