股票数据Scrapy爬虫

功能描述：

　　技术路线：scrapy

　　目标：获取上交所和深交所所有股票的名称和交易信息

　　输出：保存到文件中

数据网站的确定

　　获取股票列表：

　　　　东方财富网：http://quote.eastmoney.com/stock_list.html

　　获取个股信息：

　　　　百度股票：https://gupiao.baidu.com/stock/

　　　　单个股票：https://gupiao.baidu.com/stock/sz002439.html

步骤：

　　步骤1：建立工程和Spider模板

D:\pycodes>scrapy startproject BaiduStocks

New Scrapy project 'BaiduStocks', using template directory 'd:\\users\\bj\\appdata\\local\\programs\\python\\python36\\lib\\site-packages\\scrapy\\templates\\project', created in:

    D:\pycodes\BaiduStocks

You can start your first spider with:

    cd BaiduStocks

    scrapy genspider example example.com

D:\pycodes>cd BaiduStocks

D:\pycodes\BaiduStocks>scrapy genspider stocks baidu.com

Created spider 'stocks' using template 'basic' in module:

  BaiduStocks.spiders.stocks

进一步修改spiders/stocks.py文件

　　步骤2：编写Spider

　　　　配置stocks.py文件

　　　　修改对返回页面的处理

　　　　修改对新增URL爬取请求的处理

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

import scrapy

import re

class StocksSpider(scrapy.Spider):

    name = 'stocks'

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

    def parse(self, response):

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

            try:

                stock = re.findall(r"[s][hz]\d{6}",href)[0]

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

                yield scrapy.Request(url,callback=self.parse_stock)#callback给出了处理这个url对应响应的处理函数，为了与当前页面的处理函数作区分，定义一个新的函数叫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]

            try:

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

            except:

                val = '--'

            infoDict[key]=val

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

        yield infoDict

　　步骤3：编写Item Pipelines（对我们后期提取的数据做相关的处理）

　　　　配置pipelines.py文件

　　　　定义对爬取项（Scraped Item）的处理类

　　　　　　pipelines.py这里面的每一个类都是对一个item进行处理的一个过程

　　　　　　尝试新定义一个类，通过配置文件让框架找到新定义的类，并且用这个类来处理spider提取的相关的item类的信息

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

# Define your item pipelines here

#

# Don't forget to add your pipeline to the ITEM_PIPELINES setting

# See: https://doc.scrapy.org/en/latest/topics/item-pipeline.html

class BaidustocksPipeline(object):

    def process_item(self, item, spider):

        return item

class BaidustocksInfoPipeline(object):

    def open_spider(self,spider):#指的是当一个爬虫被调用时，对应的pipeline启动的方法

        self.f = open('BaiduStockInfo.txt','w')

    def close_spider(self,spider):#指的是一个爬虫关闭时或结束时，pipeline对应的方法

        self.f.close()

    def process_item(self,item,spider):#对每一个item项进行处理时，对应的方法,也是pipeline中最主体的函数

        try:

            line = str(dict(item)) + '\n'

            self.f.write(line)

        except:

            pass

        return item

　　　　配置ITEM_PIPELLINES选项修改配置文件settings.py

配置前

配置后

股票数据Scrapy爬虫-LMLPHP

在ITEM_PIPELLINES里将自己定义BaidustockInfoPipeline写到其中

综述

生成了一个spider，它能够从东方财富网获得股票的列表并且针对每一个股票列表生成一个百度股票的链接，并向这个百度股票的链接进行信息爬取，对于爬取后的信息，经过spider的处理，我们提取出其中的关键信息，形成字典，并且将这个字典以item类的形式给到了item pipelines进行后续处理

执行程序scrapy crawl stocks

优化

优化目的：进一步提高scrapy爬虫的爬取速度，想提高爬取速度，要依靠scrapy框架提供的相关的参数

scrapy框架一共提供了四个与性能相关的配置参数，这四个都与并发连接有关系
