node.js - Hoe kom je van "TypeError: req.pipe is not a function" af in nestjs en fastify

Ik probeerde een bestand te uploaden met NestJS/Fastify en TypeScript

dit is main.ts

async function bootstrap() {
  //file upload with fastify
  const fastifyAdapter = new FastifyAdapter();
  fastifyAdapter.register(fmp, {
    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,
    fastifyAdapter,
  );
 await app.listen(3000);
  Logger.log('application started on http://localhost:3000', 'Bootstrap');
}
bootstrap();

en dit is file.controller.ts

@Post()
  @UseInterceptors(FileInterceptor('image'))
  @ApiConsumes('multipart/form-data')
  @ApiBody({
    description: 'logo',
    type: UploadFileDto,
  })
  uploadedFile(@UploadedFile() file) {
    const response = {
      originalname: file.originalname,
      filename: file.filename,
    };
    return response;
  }

na het uploaden van een bestand naar deze actie, gooit de code een uitzondering zoals deze

hoe kan ik het probleem oplossen???

Antwoord #1

Je kunt de FastifyAdapter niet gebruiken met de FileInterceptor. Dat staat ook aan het begin van de documentatie. Als je Fastify en een bestandupload wilt gebruiken, moet je je eigen interceptor daarvoor maken.

Antwoord #2

Probleem opgelost, zoals Jay McDaniel al aangaf konden we de FastifyAdapter niet gebruiken met de FileInterceptor. Ik heb het probleem opgelost met deze kleine code.

import {
  Controller,
  Logger,
  Post,
  Req,
  Res,
} from '@nestjs/common';
import * as fs from 'fs';
import * as path from 'path';
import * as pump from 'pump';
const logger = new Logger('FileController');

@ApiTags('File')
@Controller('api/file')
export class FileController {
  @Post()
  upload(@Req() req: any, @Res() reply: any): void {
      const mp = req.multipart(
      (field: any, file: any, filename: any, encoding: any, mimeType: any) => {
        console.log('save file from request ---- ', field, filename, mimeType);
        file.on('limit', () => logger.error('SIZE_LIMITED'));

        const filePath = path.resolve('./'+filename);
        const writeStream = fs.createWriteStream(filePath);
        pump(file, writeStream);
        writeStream.on('finish', () => {
          reply.code(200).send();
        });
      },

      (error: any) => {
        if (error) {
          logger.error(error);
          reply.code(500).send();
        }
      },
    );
    mp.on('partsLimit', () => logger.error('MAXIMUM_NUMBER_OF_FORM_PARTS'));
    mp.on('filesLimit', () => logger.error('MAXIMUM_NUMBER_OF_FILES'));
    mp.on('fieldsLimit', () => logger.error('MAXIMUM_NUMBER_OF_FIELD'));
  }
}

Ik hoop dat dit jou ook zal helpen...
