适用于与Amazon S3兼容云存储的MinIO Go SDK

MinIO Go Client SDK提供了简单的API来访问任何与Amazon S3兼容的对象存储服务。

支持的云存储:

• AWS Signature Version 4

  • Amazon S3
  • MinIO

• AWS Signature Version 2

  • Google Cloud Storage (兼容模式)
  • Openstack Swift + Swift3 middleware
  • Ceph Object Gateway
  • Riak CS

本文我们将学习如何安装MinIO client SDK，连接到MinIO，并提供一下文件上传的示例。对于完整的API以及示例，请参考Go Client API Reference。

本文假设你已经有 Go开发环境。

从Github下载

go get -u github.com/minio/minio-go

初始化MinIO Client

MinIO client需要以下4个参数来连接与Amazon S3兼容的对象存储。

参数	描述
endpoint	对象存储服务的URL
accessKeyID	Access key是唯一标识你的账户的用户ID。
secretAccessKey	Secret key是你账户的密码。
secure	true代表使用HTTPS

package main

import (
	"log"

	"github.com/minio/minio-go/v7"
	"github.com/minio/minio-go/v7/pkg/credentials"
)

func main() {
	endpoint := "play.min.io"
	accessKeyID := "Q3AM3UQ867SPQQA43P2F"
	secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
	useSSL := true

	// 初使化 minio client对象。
	minioClient, err := minio.New(endpoint, &minio.Options{
		Creds:  credentials.NewStaticV4(accessKeyID, secretAccessKey, ""),
		Secure: useSSL,
	})
	if err != nil {
		log.Fatalln(err)
	}

	log.Printf("%#v\n", minioClient) // minioClient初使化成功
}

示例-文件上传

本示例连接到一个对象存储服务，创建一个存储桶并上传一个文件到存储桶中。

我们在本示例中使用运行在 https://play.min.io 上的MinIO服务，你可以用这个服务来开发和测试。示例中的访问凭据是公开的。

FileUploader.go

package main

import (
	"context"
	"log"

	"github.com/minio/minio-go/v7"
	"github.com/minio/minio-go/v7/pkg/credentials"
)

func main() {
	ctx := context.Background()
	endpoint := "play.min.io"
	accessKeyID := "Q3AM3UQ867SPQQA43P2F"
	secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
	useSSL := true

	// 初使化 minio client对象。
	minioClient, err := minio.New(endpoint, &minio.Options{
		Creds:  credentials.NewStaticV4(accessKeyID, secretAccessKey, ""),
		Secure: useSSL,
	})
	if err != nil {
		log.Fatalln(err)
	}

	// 创建一个叫mymusic的存储桶。
	bucketName := "mymusic"
	location := "us-east-1"

	err = minioClient.MakeBucket(ctx, bucketName, minio.MakeBucketOptions{Region: location})
	if err != nil {
		// 检查存储桶是否已经存在。
		exists, errBucketExists := minioClient.BucketExists(ctx, bucketName)
		if errBucketExists == nil && exists {
			log.Printf("We already own %s\n", bucketName)
		} else {
			log.Fatalln(err)
		}
	} else {
		log.Printf("Successfully created %s\n", bucketName)
	}

	// 上传一个zip文件。
	objectName := "golden-oldies.zip"
	filePath := "/tmp/golden-oldies.zip"
	contentType := "application/zip"

	// 使用FPutObject上传一个zip文件。
	n, err := minioClient.FPutObject(ctx, bucketName, objectName, filePath, minio.PutObjectOptions{ContentType: contentType})
	if err != nil {
		log.Fatalln(err)
	}

	log.Printf("Successfully uploaded %s of size %d\n", objectName, n)
}

运行FileUploader

go run file-uploader.go
2016/08/13 17:03:28 Successfully created mymusic
2016/08/13 17:03:40 Successfully uploaded golden-oldies.zip of size 16253413

mc ls play/mymusic/
[2016-05-27 16:02:16 PDT]  17MiB golden-oldies.zip
