環境：
window10；python 3.6.2；scrapy 1.4.0
系統已安裝Python2，python3 共存模式
python2,3版本共存以及使用問題的記錄

• 建立專案
  由於scrapy官網的示例站 dmoz.org 403了，所以先拿美劇天堂的網站練手
  我的專案工程路徑在D:\workspaces\python\scrapy
  開啟cmd命令列工具

cd /d D:\workspaces\python\scrapy
python3 -m scrapy startproject tutorial
cd tutorial
python3 -m scrapy genspider meijutt meijutt.com
 

• 編寫爬蟲指令碼，此時工程路徑下已經自動建立了

D:\workspaces\python\scrapy\tutorial\tutorial\spiders\meijutt.py

import scrapy
from tutorial.items import MeijuttItem

class MeijuttSpider(scrapy.Spider):
    name = 'meijutt'
    allowed_domains = ['meijutt.com']
    start_urls = ['http://www.meijutt.com/new100.html']

    def
 
 parse(self, response):
        items = []
        for sel in response.xpath('//ul[@class="top-list  fn-clear"]/li'):
            item = MeijuttItem()
            item['storyName'] = sel.xpath('./h5/a/text()').extract()
            item['storyState'] = sel.xpath('./span[1]/font/text()').extract()
            if
 
 item['storyState']:
                pass
            else:
                item['storyState'] = sel.xpath('./span[1]/text()').extract()
            item['tvStation'] = sel.xpath('./span[2]/text()').extract()
            if item['tvStation']:
                pass
            else:
                item['tvStation'] = [u'未知']
            item['updateTime'] = sel.xpath('./div[2]/text()').extract()
            if item['updateTime']:
                pass
            else:
                item['updateTime'] = sel.xpath('./div[2]/font/text()').extract()
            items.append(item)
        return items

• 設定爬取陣列

D:\workspaces\python\scrapy\tutorial\tutorial\items.py

import scrapy


class TutorialItem(scrapy.Item):
    # define the fields for your item here like:
    # name = scrapy.Field()
    pass
class MeijuttItem(scrapy.Item):
    # define the fields for your item here like:
    storyName = scrapy.Field()
    storyState = scrapy.Field()
    tvStation = scrapy.Field()
    updateTime = scrapy.Field()

• 對爬取資料進行處理

D:\workspaces\python\scrapy\tutorial\tutorial\pipelines.py

import time
import sys
import importlib
importlib.reload(sys)

class TutorialPipeline(object):
    def process_item(self, item, spider):
        return item
class MeijuttPipeline(object):
    def process_item(self, item, spider):
        today = time.strftime('%Y%m%d',time.localtime())
        fileName = today + 'movie.txt'
        with open(fileName,'a') as fp:
            fp.write(item['storyName'][0] + '\t' + str(item['storyState'][0]) + '\t' + str(item['tvStation'][0]) + '\t' + str(item['updateTime'][0]) + '\n')
        return item

• 執行爬蟲

D:\workspaces\python\scrapy\tutorial>python3 -m scrapy crawl meijutt

• 檢視爬取結果
