最新某寶x-sign參數生成原理

淘寶x-sign算法解密分析

我在上一篇博客中給大家介紹了淘寶接口如何抓取，今天我來給大家介紹一下淘寶中校驗參數x-sign的生成了，現在大家都知道只要有了x-sign基本上所有事情都可以幹，包括但不僅限於商品信息，商品評價，秒殺活動等等
本文將演示如何獲取淘寶商品評價信息，以iphone11爲例 https://detail.tmall.com/item.htm?id=602659642364

抓包分析

通過charles手機抓包分析得出評價獲取參數爲如下幾個：
url：http://guide-acs.m.taobao.com/gw/mtop.taobao.rate.detaillist.get/4.0
參數：data={“rateType”:"",“hasPic”:“1”,“foldFlag”:“0”,“pageNo”:“1”,“pageSize”:“10”,“auctionNumId”:“602659642364”}
頭信息：有好多頭信息，最重要的x-sign

簽名接口調用

先放一個postman的圖片 [外鏈圖片轉存失敗,源站可能有防盜鏈機制,建議將圖片保存下來直接上傳(img-pUVSS7Nl-1588948458935)(https://github.com/Colinlyj210/x-sign/raw/master/w2.png?raw=true)]

使用說明：

1. 圖片中的請求地址並不是真實的請求地址，需要聯繫qq獲取
2. 發請求的時候必須是post json格式，可能需要協議頭Content-Type:application/json
3. token是接口校驗參數，需要聯繫qq獲取
4. 獲取簽名的時候參數值都不需要轉義，發請求抓數據的時候可能需要轉義
5. 所有參數必須使用""包起來，必須是字符串

參數說明

1. data：就是參數data，爲了避免出現編碼問題，使用base64編碼再傳給我。編碼前的data不要使用 urlencode.
2. appKey：默認"21646297"，淘寶的appKey這個值是固定，如果是淘寶系其他app，這個值不一樣
3. pv：默認"6.3"，可選"6.2"或者"6.3"
4. useMiniWua：默認"0" 需要x-mini-wua的時候，設置爲"1"，當pv="6.3"的時候，都是帶x-mini-wua返回值的
5. useWua：默認"0" 需要wua的時候，設置爲"1"
6. `如有其他疑問，或者需要幫助的請聯繫qq: 946420414

返回值說明

返回值有x-sign，x-mini-wua，wua等 需要自己發請求測試，此處不再說明
