用scrapy做的爬虫总是抓不到数据，这是交互环境下的信息，哪位大神给看看问题出在哪

引用 6 楼 a华丽的冒险 的回复:
我和楼主情况类似：
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]})#

我也遇到了，是这样解决的： 1. 抓取微博数据出现： 2017-03-28 17:52:49 [scrapy.core.engine] DEBUG: Crawled (200) <GET http://weibo.com/robots.txt> (referer: None) 2017-03-28 17:52:49 [scrapy.downloadermiddlewares.robotstxt] DEBUG: Forbidden by robots.txt: <GET http://weibo.com/p/10050583018062> 2017-03-28 17:52:49 [scrapy.core.engine] INFO: Closing spider (finished) 2. 解决办法是 在 setting.py 中： ''# Obey robots.txt rules ROBOTSTXT_OBEY = True //设置为 False 即可 就能抓出来了，问题是因为 scrapy 默认检测 robots.txt ，看是否可以抓取，如果不行，就不能用了哦！

惭愧，因为要做个实习笔试，买了本lawson的爬虫书看，不太看得懂，想照葫芦画瓢，发现自己懂得太少

蛮多小错误 最大的错误是用了rules，这是用来爬网站的，你这是爬单页而已，触发不了parse_item的 

class Country2Spider(scrapy.Spider):
    name = "country2"
    start_urls = ['http://swu.edu.cn/glfw_jxdw.html']

    def parse(self, response):
        lst=response.xpath('/html/body/div/div/div/div/div/table/tr')
        for x in lst:
            print x.xpath('td[1]/a/text()')[0].extract()
            print x.xpath('td[2]/a/text()')[0].extract()

在上一篇中，我们已经学习了如何安装并配置Redis 数据库，为搭建分布式爬虫系统打下了坚实的基础。今天，我们将继续深入探讨模块，带领大家实现基于 Scrapy 和 Redis 的分布式爬虫。Scrapy-Redis 是一个强大的插件，能够帮助我们将 Scrapy 爬虫项目轻松升级为分布式系统。通过该插件，我们可以将任务队列和爬取的结果存储在 Redis 中，从而实现多个爬虫实例的任务共享和数据同步，显著提高爬虫的效率和稳定性。Scrapy-Redis 模块简介。
