在前后端分离的开发中Mock 数据是前端开发中很重要的一个环节,前端可以不必强依赖后端接口,只需要约定好对应的数据接口,前端可以通过 Mock 模拟数据先行开发,在后端接口开发完成后,只需要切换对应的接口地址即可,可以保证项目的同步开发。
ice.js 提供了开箱即用的 Mock 方案,支持 CRUD 等操作,在启动本地调试时会自动启用 Mock 服务。

## 目录约定
只需要在项目目录下新建 `/mock` 目录,并增加 `js``ts` 文件作为 `mock` 服务文件。比如有以下的目录结构:
```markdown
├── mock
| ├── index.ts
| └── user.ts
├── src
└── package.json
```
`mock` 目录下的 `index.ts``user.ts` 会被识别为 Mock 服务文件。
如果某些文件不需要被 mock 服务解析,可以通过工程配置进行自定义:
```js title="ice.config.mts"
import { defineConfig } from '@ice/app';
export default defineConfig(() => ({
mock: {
// 忽略 mock 目录中 custom 目录下的文件以及 api.ts 文件
exclude: ["custom/**", "api.ts"]
},
}));
```

## 编写 Mock 接口
在 mock 服务文件中写入以下代码:
```ts title="./mock/user.ts"
export default {
'GET /api/users': [
{ name: 'foo', id: 0 },
{ name: 'bar', id: 1 },
],
}
```
启动调试服务后,假设启动的端口是 `3000`,直接在浏览器里访问 <http://127.0.0.1:3000/api/users> 即可看到接口返回数据。

### 请求方法
默认支持 `GET`, `POST`, `PUT`, `DELETE`, `PATCH`, `HEAD`, `OPTIONS` 请求方法。示例代码如下:
```ts
export default {
// 当 HTTP 请求方法是 GET可以省略请求方法
'/api/users': [{ name: 'foo', id: 1 }, { name: 'bar', id: 2 }],
// 等同于上面的写法
'GET /api/users': [{ name: 'foo', id: 1 }, { name: 'bar', id: 2 }],
'POST /api/user': { users: [1, 2] },
'DELETE /api/users/1': { name: 'foo' },
}
```
### 返回值
返回值支持 `String`、`Array`、`Object` 类型。比如:
```ts
export default {
// 返回值是 String 类型
'GET /api/name': 'foo',
// 返回值 Array 类型
'POST /api/users': [
{ name: 'foo', id: 0 },
{ name: 'bar', id: 1 },
],
// 返回值是 Object 类型
'DELETE /api/users/1': { name: 'bar', id: 1 },
}
```
除此以外,还可以使用函数的形式来计算返回值,这在需要动态返回接口数据时很有用,如:
```ts
import type { Request, Response } from '@ice/app';

},
}
```
## 关闭 Mock
当后端接口开发完成以后。此时可以通过以下命令关闭 Mock 服务:
```bash
# 关闭 Mock 服务
$ npm run start -- --no-mock
```
这样我们可以请求到后端返回的数据了。
## 使用 Mock.js
[Mock.js](https://github.com/nuysoft/Mock) 是一个随机生成 mock 数据的工具库,可以帮助我们快速生成随机的模拟数据。
```ts
import Mock from 'mockjs';

export default {
'GET /api/list': (req, res) => {
const list = Mock.mock({
'list|1-10': [
{
'id|+1': 1,
},
],
});
res.send({
status: 'SUCCESS',
data: {
list,
}
});
},
};
```
完整的语法请参考 [Mock.js 文档](http://mockjs.com/examples.html)。
## 处理请求数据
如果用户希望使用一些中间件来处理请求的数据(`req` 对象),可以参考以下的示例代码:
```ts
import bodyParser from 'body-parser';
import type { Request, Response } from 'express';
export default {
'POST /api/login': (req: Request, res: Response) => {
bodyParser.json({ limit: '5mb', strict: false })(req, res, () => {
console.log(req.body);
res.send({});
})
},
}
```
