MinIO 是一个基于 Apache License v2.0 开源协议的对象存储服务，与 Amazon S3 云存储服务兼容，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。在 Go 语言中，可以使用 MinIO 官方提供的 Go 客户端库与 MinIO 服务进行交互。以下是关于在 Go 语言中使用 MinIO 的详细代码如下介绍：

package minioimport ("bytes""context""fmt""github.com/minio/minio-go/v7""github.com/minio/minio-go/v7/pkg/credentials""io""log""net/url""os""path""time"
)type Minio struct {client     *minio.Client // 连接对象bucketName string // 桶名称

}// CreateBucket 创建桶
func (m Minio) CreateBucket(ctx context.Context) error {err := m.client.MakeBucket(ctx, m.bucketName, minio.MakeBucketOptions{Region: "cn-north-1"})if err != nil {// 检查存储桶是否已存在，若已存在导致的错误则忽略if exists, errExists := m.BucketExists(ctx, m.bucketName); errExists == nil && exists {return nil}return fmt.Errorf("创建存储桶失败: %v", err)}//m.logger.Info("存储桶 %s 创建成功\n", m.bucketName)return nil

func (m Minio) BucketExists(ctx context.Context, bucketName string) (bool, error) {found, err := m.client.BucketExists(ctx, bucketName)if err != nil {fmt.Println(err)return false, err}return found, nil
}// RemoveBucket 删除桶

}// UploadObject 上传文件对象

}// ReadObject 获取文件对象
func (m Minio) ReadObject(ctx context.Context, objectName string) ([]byte, error) {contentBuffer, err := m.client.GetObject(ctx, m.bucketName, objectName, minio.GetObjectOptions{})if err != nil {return nil, err}// read the content from the buffercontentBytes := new(bytes.Buffer)if _, err = io.Copy(contentBytes, contentBuffer); err != nil {return nil, err}return contentBytes.Bytes(), nil
}// StateObjects 查询文件信息

}// PresignedGetObject 创建预览地址
func (m Minio) PresignedGetObject(ctx context.Context, objectName string) (*url.URL, error) {reqParams := make(url.Values)// 若需要生成的链接直接下载文件的把下面的注释打开，需要预览的则不需要打开//reqParams.Set("response-content-disposition", "attachment; filename="+path.Base(objectName))// Generates a presigned url which expires in a day.presignedURL, err := m.client.PresignedGetObject(ctx, m.bucketName, objectName, time.Second*24*60*60, reqParams)if err != nil {return nil, err}return presignedURL, err
