## 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。
|
|||
|
|
|||

<a name="FPutObject"></a>
|
|||
|
### FPutObject(bucketName, objectName, filePath, opts PutObjectOptions) (length int64, err error)
|
|||
|
将filePath对应的文件内容上传到一个对象中。
|
|||
|
|
|||
|
当对象小于64MiB时,FPutObject直接在一次PUT请求里进行上传。当大于64MiB时,根据文件的实际大小,FPutObject会自动地将对象进行拆分成64MiB一块或更大一些进行上传。对象的最大大小是5TB。
