将 OpenAPI 规范声明文件转换为类型安全的基于 Axios 的函数。
- 😆 同时支持 [openAPI](https://www.openapis.org/) 2.0、3.0、3.1 规范
- 😎 与最流行的 HTTP 客户端 [axios](https://axios-http.com/) 进行适配
- 😉 类型安全的请求函数，轻松进行 tree shaking
- 🤔 基于 [zod](https://zod.dev/) 支持了接口出入参的校验（可选）
- 😋 支持生成原 Schema 文件以及中间处理的 Schema 文件（可选）
- 🤗 支持接口 Mock（可选）
# 安装
```shell
npm i -D openapi-axios@latest
npm i axios
```
# 使用
## 创建配置文件
```shell
npx openapi-axios init
```
将在项目根目录下创建配置文件 openapi.config.cjs：
```js
const { defineConfig } = require('openapi-axios');
/**
* openapi-axios config
* @ref https://github.com/FrontEndDev-org/openapi-axios
*/
module.exports = defineConfig({
documents: {
petStore3: 'https://petstore3.swagger.io/api/v3/openapi.json'
},
});
```
## 生成 OpenAPI 相关文件
```shell
# 根据配置文件生成typescript文件
npx openapi-axios
# 将会生成 src/apis/petStore3.ts 文件
# 将会生成 src/apis/petStore3.type.ts 文件
```

export interface Pet {

然后你可以直接导入一个函数来使用它：
```ts
import { addPet } from '@/apis/.petStore3';
// 类型安全
const { data: pet } = await addPet({
name: 'MyCat',
});
// 类型安全
console.log(pet);
```
