midway-component-s3

对接 S3 协议存储,使用的是 AWSSDK,理论支持所有支持 S3 协议的对象存储,包括 Minio

安装依赖

npm i midway-component-s3 -S

引入组件

首先,引入组件 configuration.ts 中导入:

import { Configuration } from '@midwayjs/core';
import * as s3 from 'midway-component-s3';
import { join } from 'path'

@Configuration({
  imports: [
    // ...
    s3     // 导入 s3 组件
  ],
  importConfigs: [
    join(__dirname, 'config')
  ]
})
export class MainConfiguration {
}

配置 S3

S3 组件需要配置后才能使用,需要填写 S3 服务的 endpointregionapiVersioncredentials 等参数,下面是使用 Minio 自建服务的参数。

// src/config/config.default
export default {
  // ...
  s3: {
    client: {
      endpoint: 'http://localhost:9000',
      region: 'local',
      apiVersion: '2011-06-15',
      credentials: {
        accessKeyId: 'your access key id',
        secretAccessKey: 'your secret access key',
      },
    },
  },
}

使用组件

使用 STS 获取临时秘钥

import { S3Service } from 'midway-component-s3';
import { join } from 'path';

@Provide()
export class UserService {

  @Inject()
  s3Service: S3Service;

  async getCredentails() {

    const result = await s3Service.assumeRole({
      RoleArn: '',
      RoleSessionName: '',
      Policy: JSON.stringify({
        Version: '2012-10-17', // 协议版本,固定值
        Statement: [
          {
            Effect: 'Allow',
            Action: ['s3:GetObject', 's3:GetBucketLocation'],
            Resource: ['arn:aws:s3:::*'],
          },
        ],
      }),
      DurationSeconds: 3600, // 临时凭证有效期,单位秒,最小900,最大3600
    })
    // => result.Credentials
  }
}
