老师,mongodb中怎么获取所有的字段名呢？

为啥在begin.py里执行scrapy crawl正常但img里保存不了图片，而在命令行里执行scrapy crawl就可以正常保存

老师，我按照视频写出现了图一的错误。然后我百度了一下解决办法，如图二，按照图二尝试了一下还是没有成功。

1. 视频中说chromedriver.exe安装在Python下的Script目录中，与图二冲突，到底安装在哪？

2. 我的浏览器是双核浏览器，这与出现图一的问题是否有关联？

3. 图一的错误我还是没有解决
   

老师你好，我想暗搓搓地问一个不是本节课的知识点，就是VScode怎么设置可以使得输入main可以提示if  __name__ == "__main__"，我pycharm可以提示但是VScode不行。

老师，我这su进入不管理员模式啊，直接到根目录

第2节 搞这个插件 心态都要蹦了

给的那个软件 根本打不开

最后还是网上下载了一个更高版本的

才能用。

import requests

from fake_useragent import UserAgent

from lxml import etree

#找到url地址

url='https://www.zongheng.com/rank?nav=recommend&rankType=6'

#设置请求头

headers={'User-Agent':UserAgent().edge}

#发送请求

resp=requests.get(url,headers=headers)

#解析数据

e=etree.HTML(resp.text)

#提取数据

names=e.xpath('//div[@class="rank-modules-works--main-item-title ellipsis-two-lines global-hover"]/span/text()')

authors=e.xpath('//div[@class="rank-modules-works--main-item-author ellipsis"]/span[1]/text()')

#打印数据

for n,a in zip(names,authors):

    print(n,a)

老师代码运行之后，没有出结果，2个表达式在浏览器上面试出了结果

老师我这里在爬取了两页之后会提示说编码错误，麻烦老师帮我看下

from urllib.request import Request,urlopen
from fake_useragent import UserAgent

def get_html(url):
    headers = {"User-Agent": UserAgent().chrome}
    request = Request(url,headers=headers)
    response = urlopen(request)
    return response.read().decode()

def save_html(html,filename):
    with open(filename,'w',encoding='utf-8') as f:
        f.write(html)

def main(): 
    for i in range(1,4):
        url = 'https://www.qiushibaike.com/8hr/page/{}/'.format(i)
        html = get_html(url)
        filename = '《糗事百科》第'+str(i)+'页.html'
        save_html(html,filename)
        
if __name__ == "__main__":
    main()

这个报错是什么原因？

可以获取到图片url,但是下不了

老师，关于验证码登录，我的代码没有问题，就是我不用session会话登录反而能登陆成功，用了session对象登录每次都登录不成功，求解！
