请问微信推送signature的是通过字典排序的SHA1加密算法么？

我加密完的结果也是不匹配，微信文档写的稀烂，根本和加密规则匹配不上。而且sha1加密也不说清楚有没有密钥
SHA1.gen生成sha1 digest，本机运行没问题为true,为何部署到阿里云linux服务器上就校验不一致？ String token="CGfqsarfaucxxcce"; String timestamp="1593248015"; String nonce="564544692"; String signature="af6f5627292746814189c64facccd22f8b55d01c"; String temp=SHA1.gen(token, timestamp, nonce); boolean bb= temp.equals(signature);// 本机运行没问题为true,部署到阿里云linux服务器上就校验不一致 为false加密/校验流程如下：
1）将token、timestamp、nonce三个参数进行字典序排序 2）将三个参数字符串拼接成一个字符串进行sha1加密 3）开发者获得加密后的字符串可与signature对比，标识该请求来源于微信
