小编use*_*378的帖子

我正在尝试从Nest.js服务器提供图像并添加中间件来跟踪所有请求，但我唯一能使它起作用的方法是使用express

import { NestFactory } from '@nestjs/core';
import * as bodyParser from "body-parser";
import {AppModule} from "./app.module";
import * as path from "path";
import * as express from 'express';


async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.use(bodyParser.json({limit: '50mb'}));

  app.use(function(req, res, next){
    next();
  });
  //
  app.use('/api/track/',express.static(path.join(__dirname, '/public'))); //Serves resources from public folder
  app.use('/api/track/:img', function (req, res, next) {
    console.log('do something');
    next();
  });

  await app.listen(3333);
}

bootstrap();

如何使用控制器或中间件实现它？
