我打算将我的 API 服务器集成到 Google Cloud Endpoints。
Google Cloud Endpoints 目前支持 swagger 2.0。
但是我的依赖项/库现在是最新版本。所以我想在不降级 swagger 库版本的情况下生成 swagger 2.0 yaml 文件(api 端点已经用 swagger 4.x - openapi 3.0 规范描述)。
Nestjs 和 swagger 依赖项(package.json):
...
"@nestjs/common": "^7.0.0",
"@nestjs/config": "^0.4.0",
"@nestjs/core": "^7.0.0",
"@nestjs/platform-express": "^7.0.0",
"js-yaml": "^3.14.0",
...
"@nestjs/swagger": "^4.5.4",
"swagger-ui-express": "^4.1.4",
...
和大摇大摆的生成器脚本:
import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import * as fs from 'fs'
import * as yaml from 'js-yaml'
const generateSwaggerYaml = async () => {
const app = await NestFactory.create(AppModule);
const options = new DocumentBuilder()
.setTitle('API Title')
.setDescription('API Description')
.build()
const document = SwaggerModule.createDocument(app, options)
fs.writeFileSync("./openapi-run.yaml", yaml.safeDump(document))
}
generateSwaggerYaml()
脚本的输出是 openapi 3.0 spec :(
openapi: 3.0.0
info:
title: API Title
description: API Description.
version: 1.0.0
contact: {}
tags: []
servers: []
...
是否有任何选项/方法可以从 openapi 3.0 文档生成 swagger2.0 yaml?
如何将 openapi 3.0 规范降级为 swagger 2.0 规范?
