Fix storage class related issues (#5338)

- Update startup banner to print storage class in capitals. This
makes it easier to identify different storage classes available.

- Update response metadata to not send STANDARD storage class.
This is in accordance with AWS S3 behaviour.

- Update minio-go library to bring in storage class related
changes. This is needed to make transparent translation of
storage class headers for Minio S3 Gateway.

# 适用于与Amazon S3兼容云存储的Minio Go SDK [![Slack](https://slack.minio.io/slack?type=svg)](https://slack.minio.io) [![Sourcegraph](https://sourcegraph.com/github.com/minio/minio-go/-/badge.svg)](https://sourcegraph.com/github.com/minio/minio-go?badge)
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](https://docs.minio.io/docs/golang-client-api-reference)。
本文假设你已经有 [Go开发环境](https://docs.minio.io/docs/how-to-install-golang)。
## 从Github下载
```sh
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 |
```go
package main
import (
"github.com/minio/minio-go"
"log"
)
func main() {
endpoint := "play.minio.io:9000"
accessKeyID := "Q3AM3UQ867SPQQA43P2F"
secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
useSSL := true
// 初使化 minio client对象。
minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, 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.minio.io:9000](https://play.minio.io:9000) 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
```go
package main
import (
"github.com/minio/minio-go"
"log"
)
func main() {
endpoint := "play.minio.io:9000"
accessKeyID := "Q3AM3UQ867SPQQA43P2F"
secretAccessKey := "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG"
useSSL := true
// 初使化minio client对象。
minioClient, err := minio.New(endpoint, accessKeyID, secretAccessKey, 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(bucketName, location)
if err != nil {
// 检查存储桶是否已经存在。
exists, err := minioClient.BucketExists(bucketName)
if err == nil && exists {
log.Printf("We already own %s\n", bucketName)
} else {
log.Fatalln(err)
}
}
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(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
```sh
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
```
