type Request

type Request struct {
	Query  string                 // the query method
	Data   []byte                 // data stored as a serialized byte array
	Params map[string]interface{} // request params as a map of string to interface
}

Request

Request generic request object for Query handling. Request comes with its query string and parameters

func NewRequest

func NewRequest(query string, params map[string]interface{}) (*Request, error)

NewRequest creates a new request with given BTCParams.

func NewRequestFromData

func NewRequestFromData(query string, dat []byte) *Request

NewRequestFromData creates a new request object from a byte array

func NewRequestFromObj

func NewRequestFromObj(query string, obj interface{}) (*Request, error)

NewRequestFromObj creates a new request object from an arguments struct passed. It serializes the argument struct object for a client channel and sets it against an argname. You can check example argument structs in client/request.

func (*Request) ClientDeserialize

func (r *Request) ClientDeserialize(name string, obj interface{}) error

func (*Request) GetBool

func (r *Request) GetBool(key string) (bool, error)

func (*Request) GetBytes

func (r *Request) GetBytes(key string) []byte

GetBytes retrieves a byte array

func (*Request) GetFloat64

func (r *Request) GetFloat64(key string) float64

func (*Request) GetInt

func (r *Request) GetInt(key string) int

func (*Request) GetString

func (r *Request) GetString(key string) string

GetString retrieves a string parameter saved in a request object. If a string parameter is not set or the object type of the parameter is not string an empty string is returned. All calling instances are required to check and handle empty string.

func (*Request) Parse

func (r *Request) Parse()

Parse parses the serialized parameters data and saves it to BTCParams

type Response

type Response struct {
	Data     []byte `json:"data"`
