Types

type ACL 

type ACL string

type AccessControlPolicy 

type AccessControlPolicy struct {
	Owner  Owner
	Grants []string `xml:"AccessControlList>Grant"`
}

type Bucket 

type Bucket struct {
	*Client
	Name string
}

The Bucket type encapsulates operations with an bucket.

func (*Bucket) ACL 

func (b *Bucket) ACL() (result *AccessControlPolicy, err error)

ACL returns ACL of bucket

func (*Bucket) Del 

func (b *Bucket) Del(path string) error

Del removes an object from the bucket.

func (*Bucket) DelBucket 

func (b *Bucket) DelBucket() (err error)

DelBucket removes an existing bucket. All objects in the bucket must be removed before the bucket itself can be removed.

func (*Bucket) DelMulti 

func (b *Bucket) DelMulti(objects Delete) error

DelMulti removes up to 1000 objects from the bucket.

func (*Bucket) Exists 

func (b *Bucket) Exists(path string) (exists bool, err error)

Exists checks whether or not an object exists on an bucket using a HEAD request.

func (*Bucket) Get 

func (b *Bucket) Get(path string) (data []byte, err error)

Get retrieves an object from an bucket.

func (*Bucket) GetReader 

func (b *Bucket) GetReader(path string) (rc io.ReadCloser, err error)

GetReader retrieves an object from an bucket, returning the body of the HTTP response. It is the caller's responsibility to call Close on rc when finished reading.

func (*Bucket) GetResponse 

func (b *Bucket) GetResponse(path string) (resp *http.Response, err error)

GetResponse retrieves an object from an bucket, returning the HTTP response. It is the caller's responsibility to call Close on rc when finished reading

func (*Bucket) GetResponseWithHeaders 

func (b *Bucket) GetResponseWithHeaders(path string, headers http.Header) (resp *http.Response, err error)

GetResponseWithHeaders retrieves an object from an bucket Accepts custom headers to be sent as the second parameter returning the body of the HTTP response. It is the caller's responsibility to call Close on rc when finished reading

func (*Bucket) GetResponseWithParamsAndHeaders 

func (b *Bucket) GetResponseWithParamsAndHeaders(path string, params url.Values, headers http.Header) (resp *http.Response, err error)

func (*Bucket) GetWithParams 

func (b *Bucket) GetWithParams(path string, params url.Values) (data []byte, err error)

func (*Bucket) InitMulti 

func (b *Bucket) InitMulti(key string, contType string, perm ACL, options Options) (*Multi, error)

InitMulti initializes a new multipart upload at the provided key inside b and returns a value for manipulating it.

func (*Bucket) List 

func (b *Bucket) List(prefix, delim, marker string, max int) (result *ListResp, err error)

List returns information about objects in an bucket.

The prefix parameter limits the response to keys that begin with the specified prefix.

The delim parameter causes the response to group all of the keys that share a common prefix up to the next delimiter in a single entry within the CommonPrefixes field. You can use delimiters to separate a bucket into different groupings of keys, similar to how folders would work.

The marker parameter specifies the key to start with when listing objects in a bucket. OSS lists objects in alphabetical order and will return keys alphabetically greater than the marker.

The max parameter specifies how many keys + common prefixes to return in the response. The default is 1000.

For example, given these keys in a bucket: 

index.html
index2.html
photos/2006/January/sample.jpg
photos/2006/February/sample2.jpg
photos/2006/February/sample3.jpg
photos/2006/February/sample4.jpg

Listing this bucket with delimiter set to "/" would yield the following result: 

&ListResp{
    Name:      "sample-bucket",
    MaxKeys:   1000,
    Delimiter: "/",
    Contents:  []Key{
        {Key: "index.html", "index2.html"},
    },
    CommonPrefixes: []string{
        "photos/",
    },
}

Listing the same bucket with delimiter set to "/" and prefix set to "photos/2006/" would yield the following result: 

&ListResp{
    Name:      "sample-bucket",
    MaxKeys:   1000,
    Delimiter: "/",
    Prefix:    "photos/2006/",
    CommonPrefixes: []string{
        "photos/2006/February/",
        "photos/2006/January/",
    },
}

func (*Bucket) ListMulti 

func (b *Bucket) ListMulti(prefix, delim string) (multis []*Multi, prefixes []string, err error)

ListMulti returns the list of unfinished multipart uploads in b.

The prefix parameter limits the response to keys that begin with the specified prefix. You can use prefixes to separate a bucket into different groupings of keys (to get the feeling of folders, for example).

The delim parameter causes the response to group all of the keys that share a common prefix up to the next delimiter in a single entry within the CommonPrefixes field. You can use delimiters to separate a bucket into different groupings of keys, similar to how folders would work.

func (*Bucket) Location 

func (b *Bucket) Location() (string, error)

func (*Bucket) Multi

Abort deletes an unifinished multipart upload and any previously uploaded parts for it.

After a multipart upload is aborted, no additional parts can be uploaded using it. However, if any part uploads are currently in progress, those part uploads might or might not succeed. As a result, it might be necessary to abort a given multipart upload multiple times in order to completely free all storage consumed by all parts.
