RSA签名问题
2022-06-11 09:28:00 【宇1990】
RSA参数校验问题中会遇到的问题:
1、与PHP对接的时候签名算法的问题:
PHP默认使用的是:SHA1withRSA 签名算法 而JAVA 一般我们默认的是:MD5withRSA 所以对接的时候需要统一
2、签名的问题
json的时候JSON包去排序
String jsonResult = JSON.toJSONString(transferDaoVo, SerializerFeature.MapSortField);
JSONObject object = JSON.parseObject(jsonResult);
try{
object.put("sign", RSAUtils.sign( jsonResult.getBytes() , privateKey ) );
String result = JSON.toJSONString(object, SerializerFeature.MapSortField);
return result;
}catch (Exception e){
logger.info("签名错误",e);
}普通参数的时候使用key=value&key=value的方式排序
