小红书小程序 X-sign md5加密算法_小红书sign

只需要用MD5加密请求url即可，演示如下：

一个请求包：

GET /fe_api/burdock/weixin/v2/homefeed/categories?isMale=false HTTP/1.1
Host: www.xiaohongshu.com
Connection: keep-alive
X-Sign: Xfef73cc1ac17a580f911031469f7168f
User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1 wechatdevtools/1.05.2107221 MicroMessenger/8.0.5 Language/zh_CN webview/
content-type: application/json
Accept: */*
Sec-Fetch-Site: cross-site
Sec-Fetch-Mode: cors
Sec-Fetch-Dest: empty

Accept-Encoding: gzip, deflate, br
 

/fe_api/burdock/weixin/v2/homefeed/categories?isMale=falseWSUDD

只需要把请求的url通过md5加密，即可获得X-sgin
WSUDD 是额外加密字符串，需要加上。
