Simple S3 API for Go. Docs here.
The configuration contains you credentials and bucket info.
s3c := &s3.S3{
Bucket: os.Getenv("S3_BUCKET"),
AccessKey: os.Getenv("S3_KEY"),
Secret: os.Getenv("S3_SECRET"),
Path: os.Getenv("S3_PATH"),
}
Object(path) returns a new S3 object handle bound to the configuration it was created from.
obj := s3c.Object("path/to/hello.txt")
Writing to the WriteAbortCloser returned by Writer() allows you to upload objects.
w := obj.Writer()
io.Copy(w, bytes.NewBufferString("hello world!"))
w.Close()
// NOTE: You can abort uploads with w.Abort()
Reading from the ReadCloser returned by Reader() allows you to download objects.
r, headers, err := obj.Reader()
b, err := ioutil.ReadAll(r)
Check if an object exists.
exists, err := obj.Exists()
Delete the object.
err := obj.Delete()
o := s3c.Object("hello.txt")
p := make(s3.Policy)
p.SetExpiration(3600)
p.Conditions().Bucket(s3c.Bucket)
p.Conditions().ACL(s3.PublicRead)
p.Conditions().StartsWith("$key", "hello.txt")
url, err := o.FormURL(s3.PublicRead, p)
url, err := o.ExpiringURL(time.Second*60)
