interceptor-通用grpcInterceptor

说明

http请求和响应封装

• request
  • 验证前端参数签名
• response
  • ResponseEncoderWithEncrypt 正式服加密后端响应参数
  • bff原样返回server错误及自身业务错误，正式服其它错误统一返回InternalServerError

使用示例

http

package server

import (
	userV1 "gitea.drugeyes.vip/ebm/ebm-bff/api/v1/user"
	"gitea.drugeyes.vip/ebm/ebm-bff/internal/conf"
