概述
urllib基础模块的应用，通过该类获取到url中的html文档信息，内部可以重写代理的获取方法
if PROXY_ENABLE:
self.current_proxy = ip_port = self.proxy_robot.get_random_proxy()
proxy_handler = urllib2.ProxyHandler({'http': ip_port[7:]})
handlers.append(proxy_handler)
opener = urllib2.build_opener(*handlers)
urllib2.install_opener(opener)
return opener
def get_html_body(self,url):
opener = self.__builder_proxy_cookie_opener()
request=urllib2.Request(url)
#request.add_header("Accept-Encoding","gzip,deflate,sdch")
#request.add_header("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
#request.add_header("Cache-Control","no-cache")
#request.add_header("Connection","keep-alive")
try:
response = opener.open(request,timeout=2)
http_code = response.getcode()
if http_code == 200:
if PROXY_ENABLE:
self.proxy_robot.handle_success_proxy(self.current_proxy)
html = response.read()
return html
else:
if PROXY_ENABLE:
self.proxy_robot.handle_double_proxy(self.current_proxy)
return self.get_html_body(url)
except Exception as inst:
print inst,self.current_proxy
self.proxy_robot.handle_double_proxy(self.current_proxy)
return self.get_html_body(url)
