最新某宝x-sign参数生成原理
淘宝x-sign算法解密分析
我在上一篇博客中给大家介绍了淘宝接口如何抓取，今天我来给大家介绍一下淘宝中校验参数x-sign的生成了，现在大家都知道只要有了x-sign基本上所有事情都可以干，包括但不仅限于商品信息，商品评价，秒杀活动等等
本文将演示如何获取淘宝商品评价信息，以iphone11为例 https://detail.tmall.com/item.htm?id=602659642364
抓包分析
通过charles手机抓包分析得出评价获取参数为如下几个：
url：http://guide-acs.m.taobao.com/gw/mtop.taobao.rate.detaillist.get/4.0
参数：data={“rateType”:"",“hasPic”:“1”,“foldFlag”:“0”,“pageNo”:“1”,“pageSize”:“10”,“auctionNumId”:“602659642364”}
头信息：有好多头信息，最重要的x-sign
签名接口调用
先放一个postman的图片 [外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-pUVSS7Nl-1588948458935)(https://github.com/Colinlyj210/x-sign/raw/master/w2.png?raw=true)]
使用说明：
- 图片中的请求地址并不是真实的请求地址，需要联系qq获取
- 发请求的时候必须是post json格式，可能需要协议头Content-Type:application/json
- token是接口校验参数，需要联系qq获取
- 获取签名的时候参数值都不需要转义，发请求抓数据的时候可能需要转义
- 所有参数必须使用
""包起来，必须是字符串
参数说明
- data：就是参数data，为了避免出现编码问题，使用base64编码再传给我。编码前的data不要使用 urlencode.
- appKey：默认
"21646297"，淘宝的appKey这个值是固定，如果是淘宝系其他app，这个值不一样 - pv：默认
"6.3"，可选"6.2"或者"6.3" - useMiniWua：默认
"0"需要x-mini-wua的时候，设置为"1"，当pv="6.3"的时候，都是带x-mini-wua返回值的 - useWua：默认
"0"需要wua的时候，设置为"1" - `如有其他疑问，或者需要帮助的请联系qq: 946420414
返回值说明
返回值有x-sign，x-mini-wua，wua等 需要自己发请求测试，此处不再说明
