复制代码 代码如下:

from selenium import selenium

class MySpider(CrawlSpider):

name = 'cnbeta'

allowed_domains = ['cnbeta.com']

start_urls = ['http://www.jb51.net']

rules = (

# Extract links matching 'category.php' (but not matching 'subsection.php')

# and follow links from them (since no callback means follow=True by default).

Rule(SgmlLinkExtractor(allow=('/articles/.*.htm', )),

callback='parse_page', follow=True),

# Extract links matching 'item.php' and parse them with the spider's method parse_item

)

def __init__(self):

CrawlSpider.__init__(self)

self.verificationErrors = []

self.selenium = selenium("localhost", 4444, "*firefox", "http://www.jb51.net")

self.selenium.start()

def __del__(self):

self.selenium.stop()

print self.verificationErrors

CrawlSpider.__del__(self)

def parse_page(self, response):

self.log('Hi, this is an item page! %s' % response.url)

sel = Selector(response)

from webproxy.items import WebproxyItem

sel = self.selenium

sel.open(response.url)

sel.wait_for_page_to_load("30000")

import time

time.sleep(2.5)
