MinIO简介

MinIO 是一个基于Apache License v2.0开源协议的对象存储服务。它兼容亚马逊S3云存储服务接口，非常适合于存储大容量非结构化的数据，例如图片、视频、日志文件、备份数据和容器/虚拟机镜像等，而一个对象文件可以是任意大小，从几kb到最大5T不等。

MinIO是一个非常轻量的服务,可以很简单的和其他应用的结合，类似 NodeJS, Redis 或者 MySQL

https://docs.min.io/docs/minio-quickstart-guide.html

优点

安装部署（运维简单）
单机部署和分布式
统一对象存储控制管理
丰富的SDK支持
AWS S3标准兼容
可扩展性

缺点

MinIO不支持动态增加节点(增加节点需重启集群）
官方js-sdk仅适用于基于node-js服务端开发，不支持browser下上传.
针对minio自己包装分片和断点续传js-sdk

社区版本免费

安装

docker run -d -p 9000:9000 --name minio \
  -v /media/hushow/doc/minio-data/data:/data \
  -v /media/hushow/doc/minio-data/config:/root/.minio \
  minio/minio server /data --console-address ":9001"

启动成功

控制台

对象维护
权限管理
凭证管理
参数配置

基于临时凭证流程

file

控制台申请永久凭证(配好权限)

后端JAVA-SDK上传

官方示例 https://github.com/minio/minio-java/tree/release/examples

添加依赖

    <dependency>
        <groupId>io.minio</groupId>
        <artifactId>minio</artifactId>
        <version>8.3.8</version>
    </dependency>

上传代码

@Test
public void uploadTempCredentialsTest() throws Exception {

    String bucketName = "demo";
    String ak = "AJEDFDFDFDFDFDF";
    String sk="SJEDFDFDFDFDKKK";
    String endpoint = "http://172.17.0.2:9000";

    Provider provider =
            new AssumeRoleProvider(
                    endpoint, // STS endpoint usually point to MinIO server.
                    ak, // Access key.
                    sk, // Secret key.
                    2000, // Duration seconds if available.
                    null, // Policy if available.
                    null, // Region if available.
                    null, // Role ARN if available.
                    null, // Role session name if available.
                    null, // External ID if available.
                    null);

    MinioClient minioClient = MinioClient.builder().credentialsProvider(provider).endpoint(endpoint).build();

    String fileUrl = "classpath:xx.mp4";
    File file = ResourceUtils.getFile(fileUrl);
    String key = "private/temp/"+file.getName();

    ObjectWriteResponse uploadResponse =  minioClient.putObject(PutObjectArgs.builder()
            .bucket(bucketName).object(key)
            .stream(new FileInputStream(file), file.length(), 10*1024*1024).build());

    log.info("uploadResponse:", JSONObject.toJSONString(uploadResponse));
    log.info("key:"+key);
}

前端JS-SDK上传

官方示例 https://github.com/minio/minio-js/tree/master/examples

从后台获取临时凭证

    @Test
    public void getTempCredentialsTest() throws Exception {
        String bucketName = "demo";
        String ak = "AJEDFDFDFDFDFDF";
        String sk="SJEDFDFDFDFDKKK";
        String endpoint = "http://172.17.0.2:9000";

        Provider provider =
                new AssumeRoleProvider(
                        endpoint, // STS endpoint usually point to MinIO server.
                        ak, // Access key.
                        sk, // Secret key.
                        2000, // Duration seconds if available.
                        null, // Policy if available.
                        null, // Region if available.
                        null, // Role ARN if available.
                        null, // Role session name if available.
                        null, // External ID if available.
                        null);

        Credentials credential = provider.fetch();
        log.info("ak:{} sk:{}, st:{}", credential.accessKey(), credential.secretKey(), credential.sessionToken());
    }

执行上传

  var s3Client = new minio.Client({
    endPoint: '172.17.0.2',
    port: 9000,
    useSSL: false,
    accessKey: 'B3I5CKGMCJGC4HI53AFO',
    secretKey: 'CRpCehNFCw+MLbjnVtwuUjBZWBPx1t05A7OyMxG5',
    sessionToken:'eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJhY2Nlc3NLZXkiOiJCM0k1Q0tHTUNKR0M0SEk1M0FGTyIsImV4cCI6MTY1MDQ1NzkzNywicGFyZW50IjoiQUpFREZERkRGREZERkRGIn0.sm6MmFizJNUWoROatJoDAWT-l32cnUht6PP6JctVTKVnVGPSNwAm1x-P0MjTIwYQ00-0Kb5trte0hvc4OjVXcQ'
  })

  s3Client.PutObject('demo', 'error.txt', '/media/hushow/work/wk/wk-ssop-capability/ssop-storage-js-sdk/README.md', function(e) {
    if (e) {
      return console.log(e)
    }
    console.log("Success")
  })

排查发现，mini js-sdk只能在后端跑：

https://github.com/minio/minio-js/issues/858

mini在浏览器使用方案minio-js-browser：

https://github.com/minio/minio-js/issues/855
https://codesandbox.io/s/react-minio-js-example-9xtgo
https://github.com/harshavardhana/minio-js-browser-upload
https://github.com/prakashsvmx/minio-js-web-browser-example

运行minio-js-web-browser-example代码，大文件分片上传效果如下：
