使用 NestJS 和 Fastify 时，多部分表单数据正文为空

Question

我们正在我们的应用程序中从 迁移express到。后置控制器中支持的（json正文而不是文件）在迁移后不起作用。我们已经插入，并且已接通电源。我们将不胜感激。请找到下面的代码，fastifynestJSmultipart form datatypeormswagger

async function bootstrap() {
  const { AppModule } = require('./app.module');
  const adapter = new FastifyAdapter({
    logger: true,
  });

  await adapter.register(fastifyMultipart, {
    limits: {
      fieldNameSize: 100, // Max field name size in bytes
      fieldSize: 1000000, // Max field value size in bytes
      fields: 10,         // Max number of non-file fields
      fileSize: 100,      // For multipart forms, the max file size
      files: 1,           // Max number of file fields
      headerPairs: 2000,   // Max number of header key=>value pairs
    } 
  });

  const app = await NestFactory.create<NestFastifyApplication>(
    AppModule,
    adapter,
  );
  await app.init();
  app.useGlobalPipes(new ValidationPipe());
  app.use(multer({ dest: './public/uploads/' }).single('file'));

  const config = new DocumentBuilder()
    .setTitle('Test API')
    .setDescription('Test Identity management')
    .setVersion('1.0')
    .build();
  const document = SwaggerModule.createDocument(app, config);
  SwaggerModule.setup('testapi', app, document);
  await app.listen(process.env.PORT, '0.0.0.0');
}

控制器代码是，

    @Post('/Test/V2')
    @ApiOperation({ description: 'test' })
    @ApiResponse({ status: 200 })
    public async Test(@Request() req, @Body() requestDto: RequestDto, @Response() response) {
}
