step 1: 修改配置文件config.yml，新增阿布云代理参数

  cp config.sample.yaml config.yaml

step 2: 将需要抓取的url写入redis对应的key中, 类型list

  REDIS_HOST = "localhost"
  REDIS_PORT = 6379
  REDIS_DB = 3
  REDIS_URL_KEY_LIST = "taobao_1688_urls"

step 3: 准备一些session cookie数据到redis对应的key中,类型string,前缀如下

  REDIS_SESSION_KEY_PREFIX = taobao_1688_session

step 4: 打开终端，执行爬虫

 scrapy crawl taobao1688    # 自动把redis中抓取完成的key删除


 scrapy crawl taobao1688 -a remove_key=False   # 不删除redis中抓取完成的key

step 5: 在mongo数据库中查看数据

  MONGODB_SERVER = "localhost"
  MONGODB_PORT = 27017
  MONGODB_DB = "taobao_1688"
  MONGODB_COLLECTION = "product_sku"
