我对 AWS 和 docker 还很陌生。

在我的本地开发环境中，我想从应用服务器上传文件并将文件放置在localstack s3中。但是，当我尝试从应用服务器访问localstack s3时，出现以下错误。

AggregateError [ECONNREFUSED]: 
    at internalConnectMultiple (node:net:1139:18)
    at afterConnectMultiple (node:net:1712:7) {
  code: 'ECONNREFUSED',
  '$metadata': { attempts: 3, totalRetryDelay: 105 },
  [errors]: [
    Error: connect ECONNREFUSED ::1:4566
        at createConnectionError (node:net:1675:14)
        at afterConnectMultiple (node:net:1705:16) {
      errno: -111,
      code: 'ECONNREFUSED',
      syscall: 'connect',
      address: '::1',
      port: 4566
    },
    Error: connect ECONNREFUSED 127.0.0.1:4566
        at createConnectionError (node:net:1675:14)
        at afterConnectMultiple (node:net:1705:16) {
      errno: -111,
      code: 'ECONNREFUSED',
      syscall: 'connect',
      address: '127.0.0.1',
      port: 4566
    }
  ]
}

docker-compose 配置如下。我参考了这个链接。

version: '3'

services:
  test-app:
    build:
      dockerfile: Dockerfile
      context: .
      args:
        - VARIANT=22-bookworm
    container_name: test-app
    stdin_open: true
    dns:
      # Set the DNS server to be the LocalStack container
      - 10.0.2.20
    networks:
      - ls
      
  localstack:
    container_name: localstack
    image: localstack/localstack
    ports:
      - "4566:4566"
      - "4510-4559:4510-4559"
    environment:
      - SERVICES=s3
    networks:
      ls:
        # Set the container IP address in the 10.0.2.0/24 subnet
        ipv4_address: 10.0.2.20

networks:
  ls:
    ipam:
      config:
        # Specify the subnet range for IP address allocation
        - subnet: 10.0.2.0/24

该应用程序在 NestJS 上运行，并且 S3Client 已初始化并注入以下代码片段：

import { S3Client } from '@aws-sdk/client-s3';
import type { Provider } from '@nestjs/common';

export const S3_CLIENT_TOKEN = 'S3Client';

export const s3ClientProvider: Provider = {
  provide: S3_CLIENT_TOKEN,
  useValue: new S3Client({
    endpoint: 'https://localhost.localstack.cloud:4566',
    region: 'ap-northeast-1',
    credentials: {
      accessKeyId: '',
      secretAccessKey: '',
    },
  }),
};

控制器使用以下代码片段：

  @Post()
  async uploadFile(
    @AuthorizedUser() _user: User,
    @UploadedFile() file: Express.Multer.File,
  ): Promise<void> {
    const command = new PutObjectCommand({
      Bucket: 'test',
      Key: file.filename,
      Body: await readFile(file.path),
    });

    const response = await this.s3Client.send(command);
    return;
  }

有人能帮我解决这个问题吗？提前谢谢了 :)

我期望出现购物篮不存在错误而不是网络错误，或者文件上传成功。

我尝试了此链接中的步骤，但没有得到我预期的结果。
