我试图解析一个天气网站以打印某个地方的天气.当我学习Python时,以前我使用urllib.request.urlopen(url).read()并成功了.现在,我正在将代码修改为BeautifulSoup4和request模块.下面是我的代码：

from bs4 import *
import requests
url = "https://www.accuweather.com/en/in/dhenkanal/189844/weather-forecast/189844"
data = requests.get(url)
soup = BeautifulSoup(data.text, "html.parser")
print(soup.find('div', {'class': 'info'}))

但是每次我尝试运行代码时,都会出现以下错误：

这是什么错误以及如何纠正？以及为什么它在urllib中起作用,但在请求中不起作用？

解决方法:

我直接使用了您的代码,却遇到了同样的错误,然后我遵循了如何在浏览器中发送请求.如果未将预期的标头与作为后端处理一部分使用的请求一起发送,则某些服务器不响应.原来服务器正在寻找一个名为“用户代理”的标头,该标头通常用于确定请求来自哪个客户端.现在,下面的修改代码有效！

from bs4 import *
import requests
url = "https://www.accuweather.com/en/in/dhenkanal/189844/weather-forecast/189844"

headers = {'user-agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36'}

data = requests.get(url, headers=headers)
soup = BeautifulSoup(data.text, "html.parser")

现在您可以玩汤了！
实际上,您可以传递更多的标头,例如accept,dnt,pragma,accept-language,cache-control等.这些http标头的说明是另一个问题,这是另外一次.希望能帮助到你：)
