股票数据scrapy爬虫（出自MOOC的课程《python网络爬虫与信息提取》），抓取数据失败

a华丽的冒险 2017-10-16 10:55:05

我是跟着MOOC上《python网络爬虫与信息提取》学爬虫（http://www.icourse163.org/course/BIT-1001870001）。其中第四周课程有个用scrapy爬取股票数据的示例代码。我按课件给出的代码运行后发现没有抓取到数据。
以下为spider配置代码：

# -*- coding: utf-8 -*-

import scrapy

import re





class StocksSpider(scrapy.Spider):

    name = 'stocks'

    start_urls = ['http://quote.eastmoney.com/stocklist.html']



    def parse(self, response):

        for href in response.css('a::attr(href)').extract():

            try:

                stock=re.findall(r'[s][hz]\d{6}',href)

                url='https://gupiao.baidu.com/stock/'+stock+'.html'

                yield scrapy.Request(url,callback=self.parse_stock)

            except:

                continue

    

    def parse_stock(self,response):

        infoDict={}

        stockInfo=response.css('.stock-bets')

        name=stockInfo.css('.bets-name').extract()[0]

        keyList=stockInfo.css('dt').extract()

        valueList=stockInfo.css('dd').extract()

        for i in range(len(keyList)):

            key=re.findall(r'>.*</dt>',keyList[i])[0][1:-5]#

            #key=keyList[i][0]

            try:

                val=re.findall(r'\d+\.?.*</dd>',valueList[i])[0][0:-5]#

                #val=valueList[i][0]

            except:

                val='--'

            infoDict[key]=val

                    

        infoDict.update({'股票名称':re.findall(r'\s.*\(',name)[0].split()[0]+re.findall(r'\>.*\<',name)[0][1:-1]})#

        #infoDict.update({'股票名称':name.split()[0]})

        yield infoDict
