OSS

QOR OSS aims to provide a common interface to operate files with any kinds of storages, like cloud storages, FTP, file system etc

Usage

Currently, QOR OSS provides support for file system, S3, Aliyun and Qiniu., You can easily implement your own storage strategies by implementing the interface.

type StorageInterface interface {
  Get(path string) (*os.File, error)
  GetStream(path string) (io.ReadCloser, error)
  Put(path string, reader io.Reader) (*Object, error)
  Delete(path string) error
  List(path string) ([]*Object, error)
  GetEndpoint() string
  GetURL(path string) (string, error)
}

Here's an example of how to use QOR OSS with S3. After initializing the s3 storage, The functions in the interface are available.

import (
  "github.com/oss/filesystem"
  "github.com/oss/s3"
  awss3 "github.com/aws/aws-sdk-go/s3"
)

func main() {
  storage := s3.New(s3.Config{AccessID: "access_id", AccessKey: "access_key", Region: "region", Bucket: "bucket", Endpoint: "cdn.getqor.com", ACL: awss3.BucketCannedACLPublicRead})
  // storage := filesystem.New("/tmp")

  // Save a reader interface into storage
  storage.Put("/sample.txt", reader)

  // Get file with path
  storage.Get("/sample.txt")

  // Get object as io.ReadCloser
  storage.GetStream("/sample.txt")

  // Delete file with path
  storage.Delete("/sample.txt")

  // List all objects under path
  storage.List("/")

  // Get Public Accessible URL (useful if current file saved privately)
  storage.GetURL("/sample.txt")
}
