Functions

func NewHTTPError

func NewHTTPError(statusCode int, cause error) error

NewHTTPError creates a new error that is associated with an HTTP status code and optionally an error that lead to it. Backends can use this functions to return errors that convey some semantics (e.g. 404 not found, 403 access denied, etc) while also providing an (optional) arbitrary error context (intended for humans).

func ServePrincipal

func ServePrincipal(w http.ResponseWriter, r *http.Request, options *ServePrincipalOptions)

ServePrincipal replies to requests for a principal URL.

Types

type BackendSuppliedHomeSet

type BackendSuppliedHomeSet interface {
	GetXMLName() xml.Name
}

BackendSuppliedHomeSet represents either a CalDAV calendar-home-set or a CardDAV addressbook-home-set. It should only be created via caldav.NewCalendarHomeSet or carddav.NewAddressBookHomeSet. Only to be used server-side, for listing a user's home sets as determined by the (external) backend.

type Capability

type Capability string

Capability indicates the features that a server supports.

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client provides access to a remote WebDAV filesystem.

func NewClient

func NewClient(c HTTPClient, endpoint string) (*Client, error)

NewClient creates a new WebDAV client.

If the HTTPClient is nil, http.DefaultClient is used.

To use HTTP basic authentication, HTTPClientWithBasicAuth can be used.

func (*Client) Copy

func (c *Client) Copy(ctx context.Context, name, dest string, options *CopyOptions) error

Copy copies a file.

By default, if the file is a directory, all descendants are recursively copied as well.

func (*Client) Create

func (c *Client) Create(ctx context.Context, name string) (io.WriteCloser, error)

Create writes a file's contents.

func (*Client) FindCurrentUserPrincipal

func (c *Client) FindCurrentUserPrincipal(ctx context.Context) (string, error)

FindCurrentUserPrincipal finds the current user's principal path.

func (*Client) Mkdir

func (c *Client) Mkdir(ctx context.Context, name string) error

Mkdir creates a new directory.

func (*Client) Move

func (c *Client) Move(ctx context.Context, name, dest string, options *MoveOptions) error

Move moves a file.

func (*Client) Open

func (c *Client) Open(ctx context.Context, name string) (io.ReadCloser, error)

Open fetches a file's contents.

func (*Client) ReadDir

func (c *Client) ReadDir(ctx context.Context, name string, recursive bool) ([]FileInfo, error)

ReadDir lists files in a directory.

func (*Client) RemoveAll

func (c *Client) RemoveAll(ctx context.Context, name string) error

RemoveAll deletes a file. If the file is a directory, all of its descendants are recursively deleted as well.

func (*Client) Stat

func (c *Client) Stat(ctx context.Context, name string) (*FileInfo, error)

Stat fetches a FileInfo for a single file.

type ConditionalMatch

type ConditionalMatch string

ConditionalMatch represents the value of a conditional header according to RFC 2068 section 14.25 and RFC 2068 section 14.26 The (optional) value can either be a wildcard or an ETag.

func (ConditionalMatch) ETag

func (val ConditionalMatch) ETag() (string, error)

func (ConditionalMatch) IsSet

func (val ConditionalMatch) IsSet() bool

func (ConditionalMatch) IsWildcard

func (val ConditionalMatch) IsWildcard() bool

type CopyOptions

type CopyOptions struct {
	NoRecursive bool
	NoOverwrite bool
}

type FileInfo

type FileInfo struct {
	Path     string
	Size     int64
	ModTime  time.Time
	IsDir    bool
	MIMEType string
	ETag     string
}

FileInfo holds information about a WebDAV file.

type FileSystem

type FileSystem interface {
	Open(ctx context.Context, name string) (io.ReadCloser, error)
	Stat(ctx context.Context, name string) (*FileInfo, error)
	ReadDir(ctx context.Context, name string, recursive bool) ([]FileInfo, error)
	Create(ctx context.Context, name string) (io.WriteCloser, error)
	RemoveAll(ctx context.Context, name string) error
	Mkdir(ctx context.Context, name string) error
	Copy(ctx context.Context, name, dest string, options *CopyOptions) (created bool, err error)
	Move(ctx context.Context, name, dest string, options *MoveOptions) (created bool, err error)
}

FileSystem is a WebDAV server backend.

type HTTPClient

type HTTPClient interface {
	Do(req *http.Request) (*http.Response, error)
}

HTTPClient performs HTTP requests. It's implemented by *http.Client.

func HTTPClientWithBasicAuth

func HTTPClientWithBasicAuth(c HTTPClient, username, password string) HTTPClient

HTTPClientWithBasicAuth returns an HTTP client that adds basic authentication to all outgoing requests. If c is nil, http.DefaultClient is used.

type Handler

type Handler struct {
	FileSystem FileSystem
}

Handler handles WebDAV HTTP requests. It can be used to create a WebDAV server.

func (*Handler) ServeHTTP

func (h *Handler) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP implements http.Handler.

type LocalFileSystem

type LocalFileSystem string

LocalFileSystem implements FileSystem for a local directory.

func (LocalFileSystem) Copy

func (fs LocalFileSystem) Copy(ctx context.Context, src, dst string, options *CopyOptions) (created bool, err error)

func (LocalFileSystem) Create

func (fs LocalFileSystem) Create(ctx context.Context, name string) (io.WriteCloser, error)
