方案一 @nestjs/serve-static 库映射

上代码

npm i @nestjs/serve-static

import { ServeStaticModule } from '@nestjs/serve-static';
import { join } from 'path';
const staticPath = join(__dirname, '..', '/public/');@Module({imports: [ServeStaticModule.forRoot({rootPath: staticPath,}),...],controllers: [AppController, EmailController],providers: [AppService, EmailService]
})

验证效果

访问地址你的host+路径
实例

访问地址

方案二 @nestjs/platform-express 映射（nest 自带不用安装）

直接上代码

...
import { NestExpressApplication } from '@nestjs/platform-express';
import { join } from 'path';
const staticPath = join(__dirname, '..', '/public');async function bootstrap() {const app = await NestFactory.create<NestExpressApplication>(AppModule, {logger: ['verbose']});app.useStaticAssets(staticPath)...await app.listen(3000);
}
bootstrap();

验证访问，同方案一
