routing-controllers-to-openapi v0.0.7

routing-controllers-to-openapi

routing-controllers项目构建时生成 openapi v3 schema。 通过TS文件生成AST语法树，分析AST语法树生成openapiv3数据。进而导入到postman、swagger 等平台进行数据展示。

使用

1. 安装依赖

yarn add routing-controllers-to-openapi --dev

2. 新增script命令

"scripts": {
  "gen-openapi": "gen-openapi",
}

3. 生成openapi数据

yarn gen-openapi

案例

• Controller案例代码

import { HeaderParam, JsonController, BodyParam, Post } from 'routing-controllers';
export interface Response {
  // code返回码
  code: number;
  // 返回信息
  message: string;
}

/**
 * 测试案例controller
 *
 * @export
 * @class TestController
 */
@JsonController('/example')
export default class ExampleController {
  /**
   * do something
   *
   * @param {string} orgcode 租户号
   * @param {string} name 姓名
   * @param {number} age 年龄
   * @returns {Promise<Response>}
   * @memberof ExampleController
   */
  @Post('/test')
  async getTest(
    @HeaderParam('orgcode') orgcode: string,
    @BodyParam('name') name: string,
    @BodyParam('age') age: number,
  ): Promise<Response> {
    return {
      code: 0,
      message: 'success'
    }
  }
}

Config 配置

项目根目录下创建yundoc.config.js文件

// yundoc.config.js
const path = require('path');
module.exports = {
  routePrefix: '/api', // routing-controllers路由前缀
  controllers: [path.join(process.cwd(), "./src/controller/*")],
  filterFiles: [],
  requiredType: 'typescript', // typescript | routing-controllers
  servers: [
    {
      url: 'http://127.0.0.1:3000',
      description: '开发环境域名前缀',
    }
  ],
  // 自定义统一 response 返回结构（可选）
  responseSchema: {
    type: 'object',
    properties: {
      code: {
        type: "number",
        description: "接口返回code码字段",
      },
      // data配置必填，格式固定请不要更改
      data: {
        $ref: "#Response",
      },
      msg: {
        type: "string",
        description: "接口返回信息字段",
      }
    },
    required: [
      "code",
      "data",
    ]
  }
}
