最棒的开源OSS存储 MinIO，真香！

直接用docker-compose部署 不懂的自行了解。

创建docker-compose.yml

version: '3.7'

services:
  minio:
    image: minio/minio:edge
    container_name: minio
    ports:
      - "9000:9000"
    restart: always
    command: server /data
    environment:
      MINIO_ROOT_USER: minio
      MINIO_ROOT_PASSWORD: minioadmin
    logging:
      options:
        max-size: "50M"
      driver: json-file
    volumes:
      - /data/minio_data:/data

访问 http://127.0.0.1:9000 输入 账号 minio 密码 minioadmin

点击右下角加好创建一个桶，在桶下面创建一个目录ticket/ 点击左侧桶设置规则ticket/* read and write 规则如图

不设置的话获取到的链接不是开放式链接，并且分享后只有最多7天的访问限制。

然后就可以写代码了我用的java

添加maven包

  <dependency>
    <groupId>io.minio</groupId>
    <artifactId>minio</artifactId>
    <version>3.0.10</version>
  </dependency>

下面是代码部分

    String base64Str = Base64.byteArrayToBase64(FileUtil.readBytes(imagePath));
    System.out.println(base64Str);

    byte[] imageBytes = Base64.base64ToByteArray(base64Str);

    InputStream inputStream = new ByteArrayInputStream(imageBytes);

    try{
      JSONObject jsonObject = uploadImage(inputStream, "user_4");
      System.out.println(JSONUtil.toJsonStr(jsonObject));
    }catch (Exception e){
      e.printStackTrace();
    }
  }
}

这东西很适合不想花钱用oss产品的小规模项目。
