面试官问：实际生产中如何快速的测试接口(开发环境、测试环境、生产环境)

在实际开发中测试代码时必不可少的环节，

并且通常要测试开发环境、测试环境、预发布环境、灰度测试、生产环境等

2.测试代码设计

步骤一：编写一个测试基类Base，这个基类里面主要是定义接口使用的token值、签名值的生成方法、不同环境的接口ip、测试模板等

package com.ldp.user.controller;

import cn.hutool.core.util.StrUtil;
import cn.hutool.crypto.SecureUtil;
import cn.hutool.http.HttpRequest;
import cn.hutool.http.HttpUtil;
import cn.hutool.http.Method;

import java.util.Map;
import java.util.TreeMap;
