如何在Nest.js中间件中使用服务

import { Injectable, NestMiddleware } from '@nestjs/common';
import { Request, Response, NextFunction } from 'express';

@Injectable()
export class LoggerMiddleware implements NestMiddleware {
  use(req: Request, res: Response, next: NextFunction) {
    // 中间件逻辑
    console.log('Request...');
    next();
  }
}

import { Injectable, NestMiddleware } from '@nestjs/common';
import { Request, Response, NextFunction } from 'express';
import { UserService } from './user.service';

@Injectable()
export class LoggerMiddleware implements NestMiddleware {
  constructor(private readonly userService: UserService) {}

  use(req: Request, res: Response, next: NextFunction) {
    // 使用注入的服务
    this.userService.doSomething();
    console.log('Request...');
    next();
  }
}

import { Module, NestModule, MiddlewareConsumer } from '@nestjs/common';
import { LoggerMiddleware } from './logger.middleware';

@Module({})
export class AppModule implements NestModule {
  configure(consumer: MiddlewareConsumer) {
    consumer.apply(LoggerMiddleware).forRoutes('*');
  }
}
