scrapy框架中如何使用selenuim

主程序代码：

import scrapy
from selenium import  webdriver

class SelenuimtestSpider(scrapy.Spider):
    name = 'selenuimTest'
    # allowed_domains = ['www.xxx.com']
    start_urls = ['http://war.163.com/']

    def __init__(self):
        #本地谷歌浏览器的驱动存放地址
        self.bro = webdriver.Chrome(r'D:\爬虫相关\资料\驱动程序\chromedriver_win32\chromedriver.exe')
    def parse(self, response):
        print(response.xpath('/html/body/div[1]/div[3]/div[4]/div[1]/div/div/ul/li/div/div[3]/div[1]/h3/a/text()').extract_first())


    def closed(self,spider):
        self.bro.quit()
