A unified interface to manipulate storage engine for Go.
gostorages is used in picfit to allow us switching over storage engine.
Currently, it supports the following storages:
- Amazon S3
- File system
- Viz Graphic Hub - https://documentation.vizrt.com/graphic-hub-2.4.html.
This particular storage can be used to store JPG and PNG images only at the moment.
Just run:
$ go get github.com/ulule/gostorages
It offers you a single API to manipulate your files on multiple storages.
If you are migrating from a File system storage to an Amazon S3, you don't need to migrate all your methods anymore!
Be lazy again!
To use the FileSystemStorage you must have a location to save your files.
package main
import (
"fmt"
"github.com/ulule/gostorages"
"os"
)
func main() {
tmp := os.TempDir()
storage := gostorages.NewFileSystemStorage(tmp, "http://img.example.com")
// Saving a file named test
storage.Save("test", gostorages.NewContentFile([]byte("(╯°□°）╯︵ ┻━┻")))
fmt.Println(storage.URL("test")) // => http://img.example.com/test
// Deleting the new file on the storage
storage.Delete("test")
}To use the S3Storage you must have:
- An access key id
- A secret access key
- A bucket name
- Give the region of your bucket
- Give the ACL you want to use
You can find your credentials in Security credentials.
In the following example, I'm assuming my bucket is located in european region.
package main
import (
"fmt"
"github.com/ulule/gostorages"
"github.com/mitchellh/goamz/aws"
"github.com/mitchellh/goamz/s3"
"os"
)
func main() {
baseURL := "http://s3-eu-west-1.amazonaws.com/my-bucket"
storage := gostorages.NewS3Storage(os.Getenv("ACCESS_KEY_ID"), os.Getenv("SECRET_ACCESS_KEY"), "my-bucket", "", aws.Regions["eu-west-1"], s3.PublicReadWrite, baseURL)
// Saving a file named test
storage.Save("test", gostorages.NewContentFile([]byte("(>_<)")))
fmt.Println(storage.URL("test")) // => http://s3-eu-west-1.amazonaws.com/my-bucket/test
// Deleting the new file on the storage
storage.Delete("test")
