mock的重要性
mock就是对某些不容易构造或者不容易获取的对象，用一个虚拟的对象来创建的方法。项目开发和测试过程中，遇到以下的情况，就需要模拟结果返回；
1.当另一方接口或服务还未完成，阻碍项目进度时，可以通过mock的方式，实现并发开发；
2.接口不满足目前的测试需求，虽然接口已经实现，但是个别字段/返回不满足测试要求；
mock数据实现方式：
a) 使用moco，运行moco需要java环境和moco的jar包；可参考https://www.cnblogs.com/canglongdao/p/12174046.html
b) 使用easy-mock,easymock根据其官网的解释是一个在线的可视化生产模拟数据的在线服务；
easy-mock官网 https://easy-mock.com/ 注册用户；easy-mock官网，时常登录不进去；本人在centos7下，使用docker-compose搭建了easy-mock；
a) 登录成功之后，点击‘+’，创建项目；
b) 填写信息，项目名和url都是按照自己的意愿来填写，这会为最后生成的api数据接口提供地址；
** c)在刚新增的项目下，创建接口；**
** d)写下mock的代码**
准备工作
Mock.js的语法规范
a) 数据模板中的每个属性由3部分构成：属性名|生成规则：属性值；'name|rule':value;
b) 数据占位只在属性值字符串中占个位置，并不出现在最终的属性值中；@占位符；如，first: '@FIRST',
学习mock.js语法可以参考：http://mockjs.com/examples.html
**Easy Mock **
重点来了，现在正式开始
常见使用方式；
a)静态数据
使用postman，访问上面的接口；
b)动态数据
结合Mock.js的语法，将json改造一下，可以生成随机数据，这样就避免了每次都是一样的假数据，比较符合真实的开发场景；
访问结果：

c) 响应式数据
可以模拟真实的接口一样，根据传入的参数不同获取对应的数据；
使用postman访问接口；不加参数，加参数，错误的请求方式；
