用scrapy有数据缺失，求助大佬！感谢

爬取代码如下

import scrapy
from bs4 import BeautifulSoup
from dianying.items import DianyingItem
import re

class DianyingspiderSpider(scrapy.Spider):
    name = 'dianyingSpider'
    allowed_domains = ['http://dianying.2345.com/list/----2019---.html']
    start_urls = ['http://dianying.2345.com/list/----2019---.html']
    #start_urls =[]
    #for i in range(1,3):
    #    start_urls.append('http://dianying.2345.com/list/----2019---'+str(i)+'.html')

    def parse(self, response):

        soup = BeautifulSoup(response.text,'lxml')
        anchorTag = soup.find( 'ul',attrs = {'class':"v_picTxt pic180_240 clearfix"})  
        tags = anchorTag.find_all('li',attrs={'media':re.compile('\d{6}')})   #找到不同电影的不同代码

        items = []
        for tag in tags:


            item = DianyingItem()
            item['name']= tag.find('span',attrs={'class':'sTit'}).get_text() #爬取电影名

            item['score'] = tag.find('span',attrs={'class':'pRightBottom'}).get_text().replace('分',' ') #爬取评分

            item['leadingRole'] = tag.find('span',attrs={'class':'sDes'}).get_text() #爬取主演

            items.append(item)
        return items
