1、老师，这种滑块的验证如何登陆啊？

2、老师您帮忙看看我的这个代码是不是没有进入用户登录啊？

from fake_useragent import UserAgent
import requests

login_url = ""https://www.xiami.com/api/passport/login?_s=1c4b8c7df073c5f5d87c8c3d53696a80&_xm_cf_=8AbWYVbpKjqiKTOieajzdtRP""
headers = {"user-agent": UserAgent().random}
form_data ={
    "account":"18233301608",
    "ncoSessionid":"01l226v1bCklKZGaS4pM-XkexAHIXQJKMkheIWOYlE-tp_FJVxBE0fkn51blEkQ8qSFiRJRrODbFWU2wA-FVg4l6_ijMiHM99ATKr2LD2tbEEoswFpbuRk3JI-nSWcLf2TONkhHRXe2HqoHRrsLwwAbGyPlBJUEqctiaTooWaXr7I",

    "password":"e10adc3949ba59abbe56e057f20f883e"
}
session = requests.Session()
resp = session.post(login_url,data=form_data,headers=headers)
resp.encoding = 'utf-8'
print(resp.text)

怎么样修改下代码才可以正确用户登录呢？

3、

http类型的ip能访问https 的网页吗？

https类型的IP能访问http的网页吗？

如果一个页面并没有弹出框的提示，那么设置这个函数会不会卡住，反过来，如果不会卡住，那么我是不是可以在所有的应用场合都可以运用这个函数，确定我的代码的稳定性？

老师 我这个按照百度那个测试     没有返回的html信息

老师怎么才能把得到的数据垂直展示，这样一排展示出来太长了

证书问题怎么解决？用了老师说的代码方法也不行

火狐就是运行不出来。老师

from selenium import webdriver

# 构造浏览器
fire = webdriver.Firefox()
# 发送请求，访问url
url = 'http://www.baidu.com'
fire.get(url)

视频中讲解的是

scrapy crawl douban2 -o douban2.json

可以生成json文件

而我自己的必须是

scrapy crawl douban -o douban2.json

才可以生成json文件

老师，你好！请问一下在xshell里面怎么实现爬虫程序暂停/继续功能？ 我按下CTRL+z 停止程序后，不懂怎么恢复继续了

当我重新输入 scrapy runspider xxx.py ,提示被过滤掉了  

这个和前面50章学习的定义下拉菜单区别在哪里，为什么我用50章的方法不行

结果不一样耶，而且我访问的那个登录地址，请求不是post,是get，然后就302重定向了，这是为什么？老师

怎么像老师一样可以复制这些，我的一直选择不了
