# 要访问的目标页面
targetUrl = "http://httpbin.org/ip"

# 代理服务器
proxyHost = "18.224.225.175"
proxyPort = "8080"
proxyMeta = "http://%(host)s:%(port)s" % {
    "host" : proxyHost,
    "port" : proxyPort,
    }
# 设置 http和https访问都是用HTTP代理
proxies = {
    "http" : proxyMeta,
    "https" : proxyMeta,
}
# 设置IP切换头
tunnel = random.randint(1,10000)
headers = {"Proxy-Tunnel": str(tunnel)}
resp = requests.get(targetUrl, proxies=proxies,headers=headers)
print resp.status_code
print resp.text

proxy_info = { 'host': proxyHost,'port': proxyPort}
proxy_support = urllib2.ProxyHandler({"http" :proxyMeta})
opener =urllib2.build_opener(proxy_support)
urllib2.install_opener(opener)
r = urllib2.Request(targetUrl, headers=headers)
response = urllib2.urlopen(r, timeout=30)
page = response.read()
print response
print page

执行结果：
