本文介绍了Python:在urllib2中禁用http_proxy的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
#不工作
req = urllib2.Request('http:// www.google.com')
req.set_proxy(无,无)
urllib2.urlopen(req)
#也不工作
urllib.getproxies = lambda x = None:{}
解决方案
urllib2文档建议以下内容应该有效。这是您尝试过的方法之一吗?
import urllib2
proxy_handler = urllib2.ProxyHandler {})
opener = urllib2.build_opener(proxy_handler)
page = opener.open('http://www.google.com')
I am using a proxy set as an environment variable (export http_proxy=example.com). For one call using urllib2 I need to temporarily disable this, ie. unset the http_proxy. I have tried various methods suggested in the documentation and interwebs, but so far have been unable to unset the proxy. So far I have tried:
# doesn't work
req = urllib2.Request('http://www.google.com')
req.set_proxy(None,None)
urllib2.urlopen(req)
# also doesn't work
urllib.getproxies = lambda x = None: {}
解决方案
The urllib2 documentation suggests the following should work. Is it one of the approaches you have tried?
import urllib2
proxy_handler = urllib2.ProxyHandler({})
opener = urllib2.build_opener(proxy_handler)
page = opener.open('http://www.google.com')
