Types

type Client

type Client struct {
	Gateway string
}

Client wraps interaction with a swarm HTTP gateway.

func NewClient

func NewClient(gateway string) *Client

func (*Client) Download

func (c *Client) Download(hash, path string) (*File, error)

Download downloads a file with the given path from the swarm manifest with the given hash (i.e. it gets bzz:/<hash>/<path>)

func (*Client) DownloadDirectory

func (c *Client) DownloadDirectory(hash, path, destDir string) error

DownloadDirectory downloads the files contained in a swarm manifest under the given path into a local directory (existing files will be overwritten)

func (*Client) DownloadManifest

func (c *Client) DownloadManifest(hash string) (*api.Manifest, error)

DownloadManifest downloads a swarm manifest

func (*Client) DownloadRaw

func (c *Client) DownloadRaw(hash string) (io.ReadCloser, error)

DownloadRaw downloads raw data from swarm

func (*Client) List

func (c *Client) List(hash, prefix string) (*api.ManifestList, error)

List list files in a swarm manifest which have the given prefix, grouping common prefixes using "/" as a delimiter.

For example, if the manifest represents the following directory structure:

file1.txt file2.txt dir1/file3.txt dir1/dir2/file4.txt

Then:

- a prefix of "" would return [dir1/, file1.txt, file2.txt] - a prefix of "file" would return [file1.txt, file2.txt] - a prefix of "dir1/" would return [dir1/dir2/, dir1/file3.txt]

where entries ending with "/" are common prefixes.

func (*Client) MultipartUpload

func (c *Client) MultipartUpload(hash string, uploader Uploader) (string, error)

MultipartUpload uses the given Uploader to upload files to swarm as a multipart form, returning the resulting manifest hash

func (*Client) TarUpload

func (c *Client) TarUpload(hash string, uploader Uploader) (string, error)

TarUpload uses the given Uploader to upload files to swarm as a tar stream, returning the resulting manifest hash

func (*Client) Upload

func (c *Client) Upload(file *File, manifest string) (string, error)

Upload uploads a file to swarm and either adds it to an existing manifest (if the manifest argument is non-empty) or creates a new manifest containing the file, returning the resulting manifest hash (the file will then be available at bzz:/<hash>/<path>)

func (*Client) UploadDirectory

func (c *Client) UploadDirectory(dir, defaultPath, manifest string) (string, error)

UploadDirectory uploads a directory tree to swarm and either adds the files to an existing manifest (if the manifest argument is non-empty) or creates a new manifest, returning the resulting manifest hash (files from the directory will then be available at bzz:/<hash>/path/to/file), with the file specified in defaultPath being uploaded to the root of the manifest (i.e. bzz:/<hash>/)

func (*Client) UploadManifest

func (c *Client) UploadManifest(m *api.Manifest) (string, error)

UploadManifest uploads the given manifest to swarm
