Python实现自动回复讨论功能的脚本分享
时间：2022-10-31 10:30:43
这个脚本花了我比较长的时间才完成的，因为调试的过程有些许麻烦...不过最终还是解决了，想看效果如何，请往下看！
实现过程
又双叒叕是Get_cookie.py了兄弟，看过我《小玩意儿》专栏文章的都能看烂了，但别说，还真好用，登录一次，一劳永逸，就靠它了~，话不多说，直接上号
上码
（记得在三十秒内登录哦~）
from selenium import webdriver
import time
import json
driver = webdriver.Chrome()
driver.maximize_window()
driver.get('https://www.icourse163.org/')
time.sleep(30)
dictCookies = driver.get_cookies()
jsonCookies = json.dumps(dictCookies) # 转换成字符串保存
with open('moocCookie.txt', 'w') as f:
f.write(jsonCookies)
print("cookies保存成功")一步拿捏讨论
以前回复讨论咱们讲究的是什么？讲究的是灵活运用Ctrl C和Ctrl V，讲究的是快准狠
现在回复讨论咱们讲究的是什么？讲究的是能不用手就不用手，讲究的是一个 automation，科技是第一生产力呀兄弟们
什么？相应模块怎么下载？pip install 模块名 就完事了兄弟~
什么？chromedriver怎么配置？看这篇文章就完事兄弟~

什么？不会搞？看下图干就完事了兄弟
