如何从postman获取CSV文件并在NestJs上转换为数组

import { Controller, Post, UseInterceptors, UploadedFile } from '@nestjs/common';
import { FileInterceptor } from '@nestjs/platform-express';
import * as csvParser from 'csv-parser';

@Controller('csv')
export class CsvController {
  @Post('upload')
  @UseInterceptors(FileInterceptor('file'))
  async uploadCsv(@UploadedFile() file) {
    const results = [];
    return new Promise((resolve, reject) => {
      file
        .pipe(csvParser())
        .on('data', (data) => results.push(data))
        .on('end', () => resolve(results))
        .on('error', (error) => reject(error));
    });
  }
}
