如何用Socksipy遍历代理列表

Question

出于某种原因，我可以让这个工作，使用单个代理的时候一切似乎都正常。

#This works
import socks
import urllib2
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, '68.xx.193.xx', 666)
socks.wrapmodule(urllib2)
print urllib2.urlopen('http://automation.whatismyip.com/n09230945.asp').read()

&

#This doesn't
import socks
import urllib2
proxies=['68.xx.193.xx','xx.178.xx.70','98.xx.84.xx','83.xx.86.xx']
ports=[666,1080,859,910]
for i in range(len(proxies)):
    socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, repr(proxies[i]), ports[i])
    socks.wrapmodule(urllib2)
    print urllib2.urlopen('http://automation.whatismyip.com/n09230945.asp').read()

错误：

Traceback (most recent call last):
  File "/home/zer0/Aptana Studio 3 Workspace/sy/src/test.py", line 38, in <module>
    print urllib2.urlopen('http://automation.whatismyip.com/n09230945.asp').read()

    response = self._open(req, data)

    '_open', req)

运行这个：

proxies=['68.xx.193.xx','xx.178.xx.70','98.xx.84.xx','83.xx.86.xx']
ports=[666,1080,859,910]
for i in range(len(proxies)):
    print (repr(proxies[i]), ports[i])

你会得到：

("'68.xx.193.xx'", 666)
("'xx.178.xx.70'", 1080)
("'98.xx.84.xx'", 859)
("'83.xx.86.xx'", 910)

你在用 repr 这个函数的时候，添加了不需要的引号，所以 urllib2 把它当成了主机名，而不是IP地址。把它去掉就没问题了。
