-## 1. Constructor
-<a name="Minio"></a>
-
-### New(endpoint, accessKeyID, secretAccessKey string, ssl bool) (*Client, error)
-Initializes a new client object.
-
-__Parameters__
-
-|Param   |Type   |Description   |
-|:---|:---| :---|
-|`endpoint`   | _string_  |S3 compatible object storage endpoint   |

-|`secretAccessKey`  | _string_  |Secret key for the object storage |
-|`ssl`   | _bool_  | If 'true' API requests will be secure (HTTPS), and insecure (HTTP) otherwise  |
-
-### NewWithRegion(endpoint, accessKeyID, secretAccessKey string, ssl bool, region string) (*Client, error)
-Initializes minio client, with region configured. Unlike New(), NewWithRegion avoids bucket-location lookup operations and it is slightly faster. Use this function when your application deals with a single region.

-## 1. 构造函数
-<a name="Minio"></a>
-
-### New(endpoint, accessKeyID, secretAccessKey string, ssl bool) (*Client, error)
-初使化一个新的client对象。
-
-__参数__
-
-|参数   | 类型   |描述   |
-|:---|:---| :---|
-|`endpoint`   | _string_  |S3兼容对象存储服务endpoint   |
-|`accessKeyID`  |_string_   |对象存储的Access key |
-|`secretAccessKey`  | _string_  |对象存储的Secret key |
-|`ssl`   | _bool_  |true代表使用HTTPS |
-
-### NewWithRegion(endpoint, accessKeyID, secretAccessKey string, ssl bool, region string) (*Client, error)
-初使化minio client,带有region配置。和New()不同的是，NewWithRegion避免了bucket-location操作，所以会快那么一丢丢。如果你的应用只使用一个region的话可以用这个方法。

-###  开发者指南
-
-``minio-go``欢迎你的贡献。为了让大家配合更加默契，我们做出如下约定：
-
-* fork项目并修改，我们鼓励大家使用pull requests进行代码相关的讨论。
-    - Fork项目
-    - 创建你的特性分支 (git checkout -b my-new-feature)
-    - Commit你的修改(git commit -am 'Add some feature')
-    - Push到远程分支(git push origin my-new-feature)
-    - 创建一个Pull Request
-
-* 当你准备创建pull request时，请确保：
-    - 写单元测试，如果你有什么疑问，请在pull request中提出来。
-    - 运行`go fmt`
-    - 将你的多个提交合并成一个提交： `git rebase -i`。你可以强制update你的pull request。
-    - 确保`go test -race ./...`和`go build`完成。
-      注意：go test会进行功能测试，这需要你有一个AWS S3账号。将账户信息设为``ACCESS_KEY``和``SECRET_KEY``环境变量。如果想运行简版测试，请使用``go test -short -race ./...``。
-
-* 请阅读 [Effective Go](https://github.com/golang/go/wiki/CodeReviewComments) 
-    - `minio-go`项目严格符合Golang风格
-    - 如果您看到代码有问题，请随时发一个pull request
