uri

Documentation

Overview

Package uri provides support for NDEF Payloads of URI type. It follows the NFC Forum URI Record Type Definition specification (NFCForum-TS-RTD_URI_1.0).

The Payload type implements the RecordPayload interface from ndef, so it can be used as ndef.Record.Payload.

URIProtocols provides a mapping between the first byte if a NDEF Payload of type "U" (URI) and the string value for the protocol.

Types

type Payload

type Payload struct {
	IdentCode byte
	URIField  string
}

Payload represents a NDEF Record Payload of Type "U".

func New

func New(uriStr string) *Payload

New returns a pointer to an Payload object. The Identifier code is automatically set based on the provided string.

func (*Payload) Len

func (u *Payload) Len() int

Len is the length of the byte slice resulting of Marshaling.

func (*Payload) Marshal

func (u *Payload) Marshal() []byte

Marshal returns the bytes representing the payload of a Record of URI type.

func (*Payload) String

func (u *Payload) String() string

String returns the URI string.

func (*Payload) Type

func (u *Payload) Type() string

Type returns the Uniform Resource Name for URIs.

func (*Payload) Unmarshal

func (u *Payload) Unmarshal(buf []byte)

Unmarshal parses the payload of a URI type record.
