個人使用のためにpythonスクリプトを作成していますが、ウィキペディアでは機能しません...
この作品:
import urllib2, sys
from bs4 import BeautifulSoup
site = "http://youtube.com"
page = urllib2.urlopen(site)
soup = BeautifulSoup(page)
print soup
これは機能しません:
import urllib2, sys
from bs4 import BeautifulSoup
site= "http://en.wikipedia.org/wiki/StackOverflow"
page = urllib2.urlopen(site)
soup = BeautifulSoup(page)
print soup
これはエラーです:
Traceback (most recent call last):
File "C:\Python27\wiki.py", line 5, in <module>
page = urllib2.urlopen(site)
File "C:\Python27\lib\urllib2.py", line 126, in urlopen

現在のコード内:

変更されたバージョンが機能する理由は、ウィキペディアがUser-Agentが「人気のあるブラウザ」であるかどうかをチェックするためです。
