Types

type Codec

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

Codec creates a CodecRequest to process each request.

func NewCodec

func NewCodec() *Codec

NewCodec returns a new JSON Codec.

func NewCustomCodec

func NewCustomCodec(encSel rpc.EncoderSelector) *Codec

func (*Codec) NewRequest

func (c *Codec) NewRequest(r *http.Request) rpc.CodecRequest

NewRequest returns a CodecRequest.

type CodecRequest

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

func (*CodecRequest) Method

func (c *CodecRequest) Method() (string, error)

Method returns the RPC method for the current request.

The method uses a dotted notation as in "Service.Method".

func (*CodecRequest) ReadRequest

func (c *CodecRequest) ReadRequest(args interface{}) error

ReadRequest fills the request object for the RPC method.

ReadRequest parses request parameters in two supported forms in accordance with http://www.jsonrpc.org/specification#parameter_structures

by-position: params MUST be an Array, containing the values in the Server expected order.
