javascript - NestJS 中间件未执行

Question

从模块连接时，NestJS 类或功能中间件不会运行。它也不适用于单个路径、 Controller 或每个路径。从 main.ts 连接功能中间件可以正常工作。

//main.ts
import { ValidationPipe } from '@nestjs/common'
import { NestFactory } from '@nestjs/core'
import { FastifyAdapter, NestFastifyApplication } from '@nestjs/platform-fastify'
import { AppModule } from './app.module'

declare const module: any

async function bootstrap() {
  const app = await NestFactory.create<NestFastifyApplication>(AppModule, new FastifyAdapter())

  app.useGlobalPipes(new ValidationPipe())

  await app.listen(2100)

  if (module.hot) {
    module.hot.accept()
    module.hot.dispose(() => app.close())
  }
}
bootstrap()

//app.module.ts
import { MiddlewareConsumer, Module, NestModule } from '@nestjs/common'
import { AuthMiddleware } from './middleware/auth.middleware'
import { UserModule } from './user/user.module'

@Module({
  imports: [UserModule],
})
export class AppModule implements NestModule {
  configure(consumer: MiddlewareConsumer) {
    consumer
      .apply(AuthMiddleware)
      .forRoutes('(.*)')
  }
}

//auth.middleware.ts
import { Injectable, NestMiddleware } from '@nestjs/common'
import { FastifyRequest, FastifyReply } from 'fastify'

@Injectable()
export class AuthMiddleware implements NestMiddleware {
  use(req: FastifyRequest, res: FastifyReply, next: () => void) {
    console.log('test auth middleware')
    next()
  }
}

预期输出:测试身份验证中间件
实际:无

问题是安装“fastify”包和“@nestjs/platform-fastify”。另外，如果你删除了“fastify”包，那么“@nestjs/platform-fastify”包中​​使用的依赖也会被删除，所以它不能正常工作。如果你已经安装了这两个包，卸载“fastify”并重新安装“@nestjs/platform-fastify”。
