Example

ListBuckets()

This example shows how to List your buckets.

package main

import (
	"log"

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

func main() {
	// Requests are always secure (HTTPS) by default. Set insecure=true to enable insecure (HTTP) access.
	// This boolean value is the last argument for New().

	// New returns an Amazon S3 compatible client object. API copatibality (v2 or v4) is automatically
	// determined based on the Endpoint value.
	s3Client, err := minio.New("s3.amazonaws.com", "YOUR-ACCESS-KEY-HERE", "YOUR-SECRET-KEY-HERE", false)
	if err != nil {
	    log.Fatalln(err)
	}
	buckets, err := s3Client.ListBuckets()
	if err != nil {
		log.Fatalln(err)
	}
	for _, bucket := range buckets {
		log.Println(bucket)
	}
}
