urllib.error.HTTPError: HTTP Error 404: Not Found Python while scraping data from Metacritic

Question

我正在尝试从 Metacritic 抓取电影评级。这是抛出错误的代码部分。

text = text.replace("_","-")
user_agent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7'
headers={'User-Agent':user_agent,} 
URL = "http://metacritic.com/" + text
request=urllib.request.Request(URL,None,headers)
try:
    response = urllib.request.urlopen(request)
    data = response.read()
    soup = BeautifulSoup(data,'html.parser')
    metacritic_rating = "Metascore: " + soup.find("span",class_="metascore_w").get_text()
    send_message(metacritic_rating,chat) 
except:
    pass

我修改了我用这个写的东西：

我不能使用 requests.get() 因为这个：

我正在寻找获取页面状态代码的方法。当我使用 requests.get() 时，我能够找到一种方法。

我查看了标题为 urllib.error.HTTPError: HTTP Error 404: Not Found Python 的所有答案，但找不到任何帮助。

感谢任何帮助。

我想这就是你想要的：

import urllib


user_agent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7'
headers={'User-Agent':user_agent,} 
URL = "http://metacritic.com/" + text
request=urllib.request.Request(URL,None,headers)

try:
    response = urllib.request.urlopen(request)
    data = response.read()
    soup = BeautifulSoup(data,'html.parser')
    metacritic_rating = "Metascore: " + soup.find("span",class_="metascore_w").get_text()
    send_message(metacritic_rating,chat) 
except urllib.error.HTTPError as err:
    #print(err.code)
    if err.code == 403:
        <do something>
    else:
        pass

输出：

urllib.error.HTTPError: HTTP Error 404: Not Found Python while scraping data from Metacritic
