如果有牛人知道我活命不太理解之处的话，我会很感激的~~

打错了，囧，应该是“我上面提出的”
linux的拼音输入法总是要求太苛刻

这个，代码就是平常的抓取程序！在设置goagent之前，我以前写的抓取程序是可以运行的，但是设置之后，以前那些程序也运行不了了，所以没代码！

至于您说的，我设置了http_proxy环境变量给python，我没有进行这样的设置！肯定+确定

摘录的一些使用urllib2出错的可能：
If the URL refers to a non-
existent domain, a DNS request will result in error and you will get
an "urllib2.URLError: <urlopen error (-2, 'Name or service not
known')>". If the name resolves but the host is not reachable, the
connect code will timeout (eventually) and result in an
"urllib2.URLError: <urlopen error (113, 'No route to host')>". If the
host exists but does not have a web server running, you will get an
"urllib2.URLError: <urlopen error (111, 'Connection refused')>". If a
webserver is running but the requested page does not exist, you will
get an "urllib2.HTTPError: HTTP Error 404: Not Found".

我检查了的，网络绝对通畅，你说的后者可能会是的！我的是ubuntu系统，具体就是下载代码，运行，在chrome下设置了代理，firefox下没设置！每次翻墙的的时候，运行python prox.y！

恩，在chrome下用了一个插件swithcyproxy进行了自动设置！这个是全局的？？？将系统也进行了设置？？？？囧！

那，经历这样一个循环之后，回到原点，这个问题到底是怎么回事呢？

 给你一个代码：

#!/usr/bin/python
#coding = utf-8

import urllib2
import sys
import string
from re import sub

def analysisPage(html, txtfile):
    html = sub(r'[\s]+', '', html)
    news_html = sub(r'^.*"ADcon0">', '', html)
    while news_html.find('newslist') != -1:
        end = news_html.find("</div>")
        news = news_html[:end]
        news_html = news_html[end + 5:]
        info = sub(r'[\s]+', ',', sub(r'<[^<>]*>', ' ', news))
        txtfile.write(info)
    txtfile.write("\n\n")
        print info

def getResult(url):
    txtfile = open("cnbeta.txt", "w")
    html = urllib2.urlopen(url).read()
    html = html.decode('gbk', 'ignore').encode('utf-8')
    #print html
    analysisPage(html, txtfile)
    txtfile.close()

if __name__ == '__main__':
    if len(sys.argv) != 2:
        print "Usage: g_cnbate.py the url you want to grab"
        exit(1)
    getResult(sys.argv[1])

在我开了代理的时候，可以抓取到数据，但是没开代理的情况下，出现这样的错误：

Traceback (most recent call last):
  File "g_cnbet.py", line 37, in <module>
    getResult(sys.argv[1])
  File "g_cnbet.py", line 27, in getResult
    html = urllib2.urlopen(url).read()
  File "/usr/lib/python2.7/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.7/urllib2.py", line 400, in open
    response = self._open(req, data)
  File "/usr/lib/python2.7/urllib2.py", line 418, in _open
    '_open', req)
  File "/usr/lib/python2.7/urllib2.py", line 378, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.7/urllib2.py", line 1207, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "/usr/lib/python2.7/urllib2.py", line 1177, in do_open
    raise URLError(err)

跪求解答了！
