代碼（蜘蛛代碼）

import scrapy 
import re 
class LinsSpider(scrapy.Spider): 
    name = "lins" 
    allowed_domains = ["www.google.com"] 
    start_urls = ('https://www.google.co.in/?gfe_rd=cr&ei=78uyWPjFH8WL8Qe7kKf4BA#q=hello&*',) 
    def parse(self, response): 
     pagestr = "[email protected]" 

    yield 
    { 
      'asin' : str(re.search("^[A-Za-z0-9\.\+_-][email protected][A-Za-z0-9\._-]+\.[a-zA-Z]*$",pagestr).group(1).strip()), 
    }
