gos3

Using S3 made easier. Use S3 as you use your local file system with this simple wrapper over github.com/aws/aws-sdk-go.

Includes

• Uploading a file
• Downloading a file
• Deleting a file
• Getting a pre-signed link to the file

Example

package main

import (
    "github.com/IamFaizanKhalid/gos3"
    "io/ioutil"
    "log"
    "os"
    "time"
)

func main() {
    // Getting client
    client, err := gos3.NewClient(&gos3.Config{
        Endpoint:        "http://localhost:4566",
        Region:          "us-east-1",
        AccessKeyId:     "test",
        SecretAccessKey: "test",
    })
    if err != nil {
        log.Panicln(err)
    }

    // Select a bucket    
    bucket, err := client.SelectBucket("test-bucket")
    if err != nil {
        log.Panicln(err)
    }

    // Upload a file
    file, err := os.Open("README.md")
    if err != nil {
        log.Panicln(err)
    }

    err = bucket.Upload(file, file.Name(), "backup")
    if err != nil {
        log.Panicln(err)
    }

    // Download a file
    b, _, err := bucket.Download("backup/README.md")
    if err != nil {
        log.Panicln(err)
    }

    err = ioutil.WriteFile("README.md", b, os.ModePerm)
    if err != nil {
        log.Panicln(err)
    }

    // Get pre-signed link to the file
    link, err := bucket.GetPreSignedLink("backup/README.md", time.Hour)
    if err != nil {
        log.Panicln(err)
    }

    log.Printf("Pre-signed link: %s\n", link)

    // Delete the file
    err = bucket.Delete("backup/README.md")
    if err != nil {
        log.Panicln(err)
    }
}
