場景:

　　經常會遇到登錄需要驗證碼這樣類似的情況

解決方案:

　　1.萬能驗證碼

　　2.利用cookies來實現,問開發哪個cookies值是登錄後需要的,把這個值帶上即可

　　3.利用火狐瀏覽器的profile文件來實現(首先需要手工登錄一次,且勾選記住信息)

　　4.手工輸入(需要輸入的地方sleep一會)

實例一:

　　利用cookies登錄百度帳號

　　　　1\獲取到cookies,取得登錄的cookie

　　　　　　cookies = driver.get_cookies()

　　　　2\添加cookies,登錄帳號

　　　　　　driver.add_cookie(cookie值)

獲取到cookies值

#! /usr/bin/env python
#coding=utf-8

from selenium import webdriver
import time

driver = webdriver.Firefox()
driver.get("https://www.baidu.com/")
time.sleep(3)

driver.find_element("linkText","登錄").click()
driver.find_element("name","userName").send_keys("13560459046")
driver.find_element(
 
"name","password").send_keys("xr199122")
time.sleep(20)
#手動輸入驗證碼
driver.find_element("id","TANGRAM__PSP_10__submit").click()
time.sleep(5)

#獲取cookies值
cookies = driver.get_cookies()
print(cookies)
driver.quit()

#刪除cookies值
#driver.delete_all_cookies()

結果:

剩下的如何取到登錄的cookie,需要自己去嘗試,如果是開發中,就去問開發就行,更方便

利用cookie值,登錄百度帳號

driver = webdriver.Firefox()
driver.get("https://www.baidu.com/")
time.sleep(3)

#設置cookies值,基本格式
c1 = {‘value‘: ‘N2YTVzQX5aTWl4THpFWGhOMFp4VDk2T1MyQ0Z5bWRwRDMtcnhSN0lkQ1pZdE5aSVFBQUFBJCQAAAAAAAAAAAEAAAC~pSxhu-HF3LXE0NwyAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAJnVq1mZ1atZdk‘,

    ‘name‘: ‘BDUSS‘, 
    ‘httpOnly‘: True, 
    ‘secure‘: False, 
    ‘domain‘: ‘.baidu.com‘}

#添加cookies
driver.add_cookie(c1)
time.sleep(3)

#刷新之後觀察是否已經登錄成功
driver.refresh()
time.sleep(5)

driver.quit()

結果:

實例二:利用火狐瀏覽器的profile文件來實現(首先需要手工登錄一次,且勾選記住信息),登錄百度帳號

profile_ff = "C:/Users/Administrator/AppData/Roaming/Mozilla/Firefox/Profiles/2e4p97lg.default"

fp = webdriver.FirefoxProfile(profile_ff)

driver = webdriver.Firefox(fp)

driver.get("https://www.baidu.com/")
time.sleep(5)
driver.quit()

也可以實現免登錄
