golang 对象存储客户端接口实现

golang 对象存储客户端接口实现

对象存储标准的接口有：

• put
• get
• delete
• list

对象存储适合的文件类型：短视频，音频文件、照片、图标、pdf、word文档、电子票据。

对于超大文件的存储，有时候索引其中某一个扇区例如：&#"文件的4096偏移量处的4个字节，总不能把整个文件get下来再访问吧。 需要一个扩展的接口：

package mainimport "fmt"type myoss interface {read(key string, offset, size int64) ([]byte, error)put(src, key string) (int64, error)get(key, dst string) (int64, error)list(bucket, user, passwd string) []stringdel(key string) ([]byte, error)
}type myossc struct {host           []stringbucket         stringpart           int64up_concurrency int64access_key     stringsecret_key     string
}func (c *myossc) read(key string, offset, size int64) ([]byte, error) {fmt.Println("i am hlm oss read interface")return nil, nil
}func (c *myossc) put(src, key string) (int64, error) {return 0, nil
}func (c *myossc) get(key, dst string) (int64, error) {return 0, nil
}func (c *myossc) list(bucket, user, passwd string) []string {return []string{}
}func (c *myossc) del(key string) ([]byte, error) {return nil, nil
}func main() {fmt.Println("ext-client-minio")client := &myossc{host:           []string{"182.168.31.100/data{1..100}", "182.168.31.103/data{1..100}"},bucket:         "test",part:           32,up_concurrency: 8,access_key:     "minio123",secret_key:     "minio123",}ad("/data/dir1/dir2/dir4", 10240, 2048)
}
