request

req = urllib2.Request(url, None, headers)
response = urllib2.urlopen(req)
page_source = response.read()
return page_source
phantomjs请求页面

}
for key, value in headers.iteritems():
desire['phantomjs.page.customHeaders.{}'.format(key)] = value
driver = webdriver.PhantomJS(desired_capabilities=desire, service_args=['--load-images=yes'])#将yes改成no可以让浏览器不加载图片
return driver
