代理IP使用urllib2库提交GET、POST请求

网络上提供代理IP服务的商家是越来越多，但与此同时，选择的增加也无疑给了消费者筛选难度。除了验证服务商的资质，代理IP的有效性也是我们最为关注的问题。在一番挑选之后，终于找到了合适的代理，那么这时，我们就可以开始工作了。

下面分别说说如何代理IP是使用urllib2库提交GET、POST请求的。

如何使用代理IP提交GET请求?

import urllib2

def UseProxyToGet(proxy_ip, proxy_port):

proxy_support = urllib2.ProxyHandler({‘http’: r’http://’ + proxy_ip + ‘:’ + proxy_port})

opener = urllib2.build_opener(proxy_support, urllib2.HTTPHandler)

try:

url = "“http://httpbin.org/get?a=1&b=2"”

opener.addheaders = [

(‘Cookie’, ‘this is cookie’),

(‘Referer’, ‘this is refere’),

(‘User-Agent’, ‘this is user-agent’),

response = opener.open(url, timeout=5)

html = response.read()

print html

except urllib2.HTTPError as e:

print(‘UseProxyToGet:’, proxy_ip, ’ HTTPError:’, e)

except urllib2.URLError as e:

print(‘UseProxyToGet:’, proxy_ip, ’ URLError:’, e)

except Exception as e:

print(‘UseProxyToGet:’, proxy_ip, ’ Exception:’, e)

如何使用代理IP提交POST请求?

import urllib, urllib2

def UseProxyToPost(proxy_ip, proxy_port):

proxy_support = urllib2.ProxyHandler({‘http’: r’http://’ + proxy_ip + ‘:’ + proxy_port})

opener = urllib2.build_opener(proxy_support, urllib2.HTTPHandler)

try:

url = ““http://httpbin.org/post””

opener.addheaders = [

(‘Cookie’, ‘this is cookie’),

(‘Referer’,‘this is refere’),

(‘User-Agent’, ‘this is user-agent’),

values = {‘a’: ‘1’, ‘b’: ‘2’}

data = urllib.urlencode(values)

response = opener.open(url, data, timeout=5)

html = response.read()

print html

except urllib2.HTTPError, e:

print(‘UseProxyToPost:’, proxy_ip, ’ HTTPError:’, e)

except urllib2.URLError as e:

print(‘UseProxyToPost:’, proxy_ip, ’ URLError:’, e)

except Exception as e:

print(‘UseProxyToPost:’, proxy_ip, ’ Exception:’, e)
