Swagger-ui-express模块​​仅实例化最后定义的文档

Question

I have a Typescripted nodejs server and i'm trying to define diffrent swagger paths for seperated controllers, but the swagger-ui-express module seems to only show the last defined doc in the specific route.

index.ts for X group of controllers

import express from 'express';
import passport from 'passport';
const router = express.Router();
// import all bot routes
import { authRoute } from './auth';
import { botCrudRoute } from './bot-crud';
import { aiRoutes } from './ai';
import { categoryCrudRoute } from './categories-crud';

const swaggerUi = require('swagger-ui-express');
import { botSwaggerDoc } from './swagger';

const swaggerDoc = botSwaggerDoc;

const swaggerUiOpts = {
    explorer: false
};

// Swagger setup
router.use('/api-docs', swaggerUi.serve);
router.get('/api-docs', swaggerUi.setup(swaggerDoc, swaggerUiOpts));

index.ts for Y group of controllers

import express from 'express';
const router = express.Router();
// import all bot routes

const swaggerUi = require('swagger-ui-express');
import { adminSwaggerDoc } from './swagger';

const swaggerDoc = adminSwaggerDoc;

const swaggerUiOpts = {
    explorer: false
};

// Swagger setup
router.use('/api-docs', swaggerUi.serve);
router.get('/api-docs', swaggerUi.setup(swaggerDoc, swaggerUiOpts));

export const adminRoutes = router;

api.ts grouping all groups of controllers

'use strict';

import express from 'express';
import { Response, Request, NextFunction } from 'express';
import { adminRoutes } from './admin';
import { botRoutes } from './bot';
// import { onboardRoutes } from './onboard';

const router = express.Router();

// router.use('/onboard', onboardRoutes);
router.use('/bot', botRoutes);
router.use('/admin', adminRoutes);

export const apiRoutes = router;

server.ts

/**
 * Primary app routes.
 */
app.use('/api', apiRoutes);

example of one of the swaggerDoc's

export const botSwaggerDoc = {
    'swagger': '2.0',
    'info': {
        'version': '1.0.0',
        'title': 'Cupo embed chat bot API',
        'license': {
            'name': 'Internal use only'
        }

the swagger-ui-express module only use the last defined document as if the server keeps reference to that document...

Answer 1

I was able to get around this by serving up the HTML directly for each individual api. See below:

 // index.ts for X group of controllers const apiV1Html = swaggerUi.generateHTML( v1SwaggerDocument, ); router.use( '/docs', swaggerUi.serveFiles(v1SwaggerDocument), ); router.get('/docs', (req: any, res: any) => { res.send(apiV1Html); }); 

and for the Y group of controllers:

 // index.ts for y group of controllers const apiV2Html = swaggerUi.generateHTML( v2SwaggerDocument, ); router.use( '/docs', swaggerUi.serveFiles(v2SwaggerDocument), ); router.get('/docs', (req: any, res: any) => { res.send(apiV2Html); });
