HTTP错误404:找不到BeautifulGroup和Python

Question

我有一个脚本来抓取一个网站，但我一直得到一个“urllib.error.HTTPError：HTTP错误404:找不到”。我已经尝试将用户代理添加到头中并运行脚本，但仍然收到相同的错误。这是我的密码

from urllib.request import urlopen, Request
from bs4 import BeautifulSoup as soup
import json

atd_url = 'https://courses.lumenlearning.com/catalog/achievingthedream'

#opening up connection and grabbing page
res = Request(atd_url,headers={'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'})
uClient = urlopen(res)
page_html = uClient.read()
uClient.close()

#html parsing
page_soup = soup(page_html, "html.parser")

#grabs info for each textbook
containers = page_soup.findAll("div",{"class":"book-info"})

data = []
for container in containers:
   item = {}
   item['type'] = "Course"
   item['title'] = container.h2.text
   item['author'] = container.p.text
   item['link'] = container.p.a["href"]
   item['source'] = "Achieving the Dream Courses"
   item['base_url'] = "https://courses.lumenlearning.com/catalog/achievingthedream"
   data.append(item) # add the item to the list

with open("./json/atd-lumen.json", "w") as writeJSON:
   json.dump(data, writeJSON, ensure_ascii=False)

这是我每次运行脚本时收到的完整错误消息

改为使用请求库，这样可以：

import requests

#opening up connection and grabbing page
response = requests.get(atd_url,headers={'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.47 Safari/537.36'})

#html parsing
page_soup = soup(response.content, "html.parser")
