詳解Python之Scrapy爬蟲教程NBA球員數(shù)據(jù)存放到Mysql數(shù)據(jù)庫

獲取要爬取的URL

爬蟲前期工作

用Pycharm打開項目開始寫爬蟲文件

字段文件items

# Define here the models for your scraped items

# See documentation in:

class NbaprojectItem(scrapy.Item):
  # define the fields for your item here like:
  # name = scrapy.Field()
  # pass
  # 創(chuàng)建字段的固定格式-->scrapy.Field()

  engName = scrapy.Field()
  # 中文名
  chName = scrapy.Field()
  # 身高
