Python 3.5 urllib.request 403禁止的錯誤

Question

import urllib.request 
import urllib 
from bs4 import BeautifulSoup 


url = "https://www.brightscope.com/ratings" 
page = urllib.request.urlopen(url) 
soup = BeautifulSoup(page, "html.parser") 

print(soup.title) 

我正試圖去上面的網站，代碼不斷吐出一個403禁止的錯誤。

任何想法？

import requests 
from bs4 import BeautifulSoup 


url = "https://www.brightscope.com/ratings" 
headers = {'User-Agent':'Mozilla/5.0'} 
page = requests.get(url) 
soup = BeautifulSoup(page.text, "html.parser") 

print(soup.title) 

出來：

<title>BrightScope Ratings</title> 

首先，使用reuqests而非urllib。

比，添加headers到requests，如果沒有，網站會禁止你的，因爲默認User-Agent是爬蟲，這是網站不喜歡的。
