python - IO 错误 - 抓取网络时 - 代理问题？

Question

from urllib import urlopen
from bs4 import BeautifulSoup
import re

# Copy all of the content from the provided web page
webpage = urlopen('http://stats.espncricinfo.com/indian-premier-league-2012/engine/records/averages/batting.html?id=6680;type=tournament').read()

soup=BeautifulSoup(webpage);

commentary=soup.find_all("tr", "data2");

for i in range(10):

    for stat in commentary[i].stripped_strings:
        print stat,

    print ""

我在 eclipse 中运行这个 python 程序。我更改了网络连接中的代理条目。但我收到如下 IOError:

IOError: [Errno socket error] [Errno -2] Name or service not known

看起来您的互联网连接不稳定。错误“名称或服务未知”表示页面的 DNS 查找失败，“连接超时错误”表示您无法联系远程服务器但 DNS 查找成功。
