Hey Matt! Spaces was designed to be API compatible with AWS’s S3 API. One trade off with this approach is that the AWS signature formats can be a bit complicated. Though the main reason we went that direct was to allow people to use pre-existing tools. So, I’d encourage you to use one of the existing libraries for working S3-compatible APIs like minio-go or AWS’ Go SDK.

Here’s a quick example using minio-go:

package main

import (
    "fmt"
    "log"
    "os"

    "github.com/minio/minio-go"
)

func main() {
    accessKey := os.Getenv("DO_ACCESS_KEY")
    secKey := os.Getenv("DO_SECRET_ACCESS_KEY")
    ssl := true

    // Initiate a client using DigitalOcean Spaces.
    client, err := minio.New("nyc3.digitaloceanspaces.com", accessKey, secKey, ssl)
    if err != nil {
        log.Fatal(err)
    }

    // Create a new Space.
    err = client.MakeBucket("my-new-space", "nyc3")
    if err != nil {
        log.Fatal(err)
    }

    // List all Spaces.
    spaces, err := client.ListBuckets()
    if err != nil {
        log.Fatal(err)
    }
    for _, space := range spaces {
        fmt.Println(space.Name)
    }
}
