AWS SDK - Go (Golang)

Learn how to use the AWS SDK for Go (Golang) with Filebase.

What is AWS SDK - Go?

AWS SDKs (software development kits) help simplify coding and application development by supporting and providing code objects for use with S3-compatible services. There are a variety of different AWS SDKs, each for a different coding language. This guide covers AWS SDK - Go.

Read below to learn how to use the AWS SDK for Go with Filebase.

Prerequisites:

• Download and install Go in your environment.

• Download and install the AWS SDK for Go.

• Sign up for a free Filebase account.

• Have your Filebase Access and Secret Keys. Learn how to view your access keys here.

This guide was written using Ubuntu 20.04 and tested using the command line interface. If you are using an Integrated Development Environment (IDE), the installation of dependencies and modules will vary.

Create a Bucket

The following code example creates a new Filebase bucket. Replace the following values in the code to match your configuration:

• filebase-access-key: Your Filebase Access Key

• filebase-secret-key: Your Filebase Secret Key

• new-filebase-bucket: The Intended New Bucket Name

Bucket names must be unique across all Filebase users, be between 3 and 63 characters long, and can contain only lowercase characters, numbers, and dashes.

Buckets created through this method will be automatically created on the IPFS network.

package main

import (
	"fmt"
	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/aws/credentials"
	"github.com/aws/aws-sdk-go/service/s3"
)

func main() {
//// create a configuration
	s3Config := aws.Config{
	Credentials:      credentials.NewStaticCredentials("filebase-access-key", "filebase-secret-key", ""),
	Endpoint:         aws.String("https://s3.filebase.com"),
	Region:           aws.String("us-east-1"),
	S3ForcePathStyle: aws.Bool(true),
}

goSession, err := session.NewSessionWithOptions(session.Options{
	Config:  s3Config,
	Profile: "filebase",
})

// check if the session was created correctly.

if err != nil {
	fmt.Println(err)
}

// create a s3 client session
s3Client := s3.New(goSession)

// set parameter for bucket name
bucket := aws.String("new-filebase-bucket")

// create a bucket
_, err = s3Client.CreateBucket(&s3.CreateBucketInput{
	Bucket: bucket,
})

// print if there is an error
if err != nil {
	fmt.Println(err.Error())
return
}
}

Upload an Object

The following code example uploads an object to the specified bucket. Replace the following values in the code to match your configuration:

• filebase-access-key: Your Filebase Access Key

• filebase-secret-key: Your Filebase Secret Key

• bucket-name: Your Filebase Bucket Name

• /path/to/object/to/upload: The path to the file to upload

• object-name: The name of the object to upload

package main

import (
	"fmt"
	"github.com/aws/aws-sdk-go/aws"
	"github.com/aws/aws-sdk-go/aws/session"
	"github.com/aws/aws-sdk-go/aws/credentials"
	"github.com/aws/aws-sdk-go/service/s3"
	"os"
)

func main() {
//// create a configuration
	s3Config := aws.Config{
	Credentials:      credentials.NewStaticCredentials("filebase-access-key", "filebase-secret-key", ""),
	Endpoint:         aws.String("https://s3.filebase.com"),
	Region:           aws.String("us-east-1"),
	S3ForcePathStyle: aws.Bool(true),
}

// create a new session using the config above and profile
goSession, err := session.NewSessionWithOptions(session.Options{
	Config:  s3Config,
	Profile: "filebase",
})

// check if the session was created correctly.

if err != nil {
	fmt.Println(err)
}

// create a s3 client session
s3Client := s3.New(goSession)

//set the file path to upload
file, err := os.Open("/path/to/object/to/upload")
if err != nil {
	fmt.Println(err.Error())
return
}

defer file.Close()
// create put object input
	putObjectInput := &s3.PutObjectInput{
	Body:   file,
	Bucket: aws.String("bucket-name"),
	Key:    aws.String("object-name"),
}

// upload file
_, err = s3Client.PutObject(putObjectInput)

// print if there is an error
if err != nil {
	fmt.Println(err.Error())
return
}
}

Download an Object

The following code example downloads an object from the specified bucket. Replace the following values in the code to match your configuration:

• filebase-access-key: Your Filebase Access Key

• filebase-secret-key: Your Filebase Secret Key

• bucket-name: Your Filebase Bucket Name

• object-name: The name of the object to download

package main

import (
"fmt"

	s3Config := aws.Config{
	Credentials:      credentials.NewStaticCredentials("filebase-access-key", "filebase-secret-key", ""),
	Endpoint:         aws.String("https://s3.filebase.com"),
	Region:           aws.String("us-east-1"),
	S3ForcePathStyle: aws.Bool(true),

goSession, err := session.NewSessionWithOptions(session.Options{
	Config:  s3Config,
	Profile: "filebase",
})

// check if the session was created correctly.
if err != nil {
	fmt.Println(err)

// create a s3 client session
s3Client := s3.New(goSession)

// create put object input
getObjectInput := &s3.GetObjectInput{
	Bucket: aws.String("bucket-name"),
	Key:    aws.String("object-name"),
}

// get file
_, err = s3Client.GetObject(getObjectInput)

// print if there is an error
if err != nil 
	fmt.Println(err.Error())
return
}
}
