									}

									def get_all(url,key):

									  for page in range(1,200,2):

									    params = {

									      'keyword':key,

									      'enc':'utf-8',

									      'page':page

									    }

									    num = int((int(page)+1)/2)

									    try:

									      response = requests.get(url=url,params=params,headers=headers)

									      # 转码

									      content = response.text.encode(response.encoding).decode(response.apparent_encoding)

									      data_all = re.findall('<div class="p-price">.*?<i>(.*?)</i>.*?<div class="p-name p-name-type-2">.*?title="(.*?)"'

									                 '.*?<div class="p-shop".*?title="(.*?)"',content,re.s)

									      for i in data_all:

									        with open(key + '.txt', 'a+', encoding='utf-8') as f:

									          f.write('店铺名称：' + i[2]+'\n'+'商品名称：'+i[1]+'\n'+'价格:'+i[0]+'\n\n')

									        print('第'+str(num)+'页'+'数据下载中....')

									    except exception as e:
