# 适用于与Amazon S3兼容云存储的MinIO Go SDK [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.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.min.io/docs/golang-client-api-reference)。
|
|
|
|
|
|
|
|
|
|
本文假设你已经有 [Go开发环境](https://golang.org/doc/install)。
|
|

|
|
## 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 |
|
|
|
|
|
|
|

|
|
|
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](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。
