import re
# 请求头
headers = {
  'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36'

    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:
      print(e)
 
if __name__ == '__main__':
  print('输入要搜索的内容，获取京东商城里面的商品名称，店铺名称，商品价格')
  key = input('输入搜索内容：')
  url = 'https://search.jd.com/Search?'
