淘宝关键词搜索及X5滑块
环境
根据关键词获取品牌列表
先根据搜索关键词获取到所有的品牌id：也就是ppath参数，目的是这样可以筛选更精准的数据，因为默认只显示100页数据

根据关键词、品牌、销量搜索商品列表
具体的参数多抓几个包对比一下，很容易就分析出来了

# 第一页的时候请求参数不一样
if page == 1:

params['data-key'] = 's,ps'
params['s'] = (int(page) - 1) * 44
else:
params['data-value'] = int(page) * 44
params['s'] = (int(page)-1) * 44
response = requests.get(url, headers=headers, params=params)
return response.text
滑块处理
触发滑块后，搜索并定位appkey，抓到punish.js
提取验证所需参数：
''appkey': 'X82Y__4efeef942d19c56bafab18ba3da969f4'
'token': '1c797559e58912c4ee46af4bd6371aec',
