Functions

func ParseFloat64OrReturnBadRequest

func ParseFloat64OrReturnBadRequest(w http.ResponseWriter, s string, defaultIfEmpty float64) (n float64, ok bool)

ParseFloat64OrReturnBadRequest converts s to a float64 value. It returns a default value, defaultIfEmpty, if the string is empty.

func ParseInt64OrReturnBadRequest

func ParseInt64OrReturnBadRequest(w http.ResponseWriter, s string) (n int64, ok bool)

ParseInt64OrReturnBadRequest converts s to a int64 value.

func ParseUint64OrReturnBadRequest

func ParseUint64OrReturnBadRequest(w http.ResponseWriter, s string) (n uint64, ok bool)

ParseUint64OrReturnBadRequest converts s to a uint64 value.

func PostProcessResponse

func PostProcessResponse(w http.ResponseWriter, cdc *codec.Codec, response interface{}, indent bool)

PostProcessResponse performs post processing for a REST response.

func ReadRESTReq

func ReadRESTReq(w http.ResponseWriter, r *http.Request, cdc *codec.Codec, req interface{}) bool

ReadRESTReq reads and unmarshals a Request's body to the the BaseReq stuct. Writes an error response to ResponseWriter and returns true if errors occurred.

func WriteErrorResponse

func WriteErrorResponse(w http.ResponseWriter, status int, err string)

WriteErrorResponse prepares and writes a HTTP error given a status code and an error message.

func WriteSimulationResponse

func WriteSimulationResponse(w http.ResponseWriter, cdc *codec.Codec, gas uint64)

WriteSimulationResponse prepares and writes an HTTP response for transactions simulations.

Types

type BaseReq

type BaseReq struct {
	From          string       `json:"from"`
	Memo          string       `json:"memo"`
	ChainID       string       `json:"chain_id"`
	AccountNumber uint64       `json:"account_number"`
	Sequence      uint64       `json:"sequence"`
	Fees          sdk.Coins    `json:"fees"`
	GasPrices     sdk.DecCoins `json:"gas_prices"`
	Gas           string       `json:"gas"`
	GasAdjustment string       `json:"gas_adjustment"`
	Simulate      bool         `json:"simulate"`
}

BaseReq defines a structure that can be embedded in other request structures that all share common "base" fields.

func NewBaseReq

func NewBaseReq(
	from, memo, chainID string, gas, gasAdjustment string, accNumber, seq uint64,
	fees sdk.Coins, gasPrices sdk.DecCoins, simulate bool,
) BaseReq

NewBaseReq creates a new basic request instance and sanitizes its values

func (BaseReq) Sanitize

func (br BaseReq) Sanitize() BaseReq

Sanitize performs basic sanitization on a BaseReq object.

func (BaseReq) ValidateBasic

func (br BaseReq) ValidateBasic(w http.ResponseWriter) bool

ValidateBasic performs basic validation of a BaseReq. If custom validation logic is needed, the implementing request handler should perform those checks manually.

type ErrorResponse

type ErrorResponse struct {
	Code  int    `json:"code,omitempty"`
	Error string `json:"error"`
}

ErrorResponse defines the attributes of a JSON error response.

func NewErrorResponse

func NewErrorResponse(code int, err string) ErrorResponse

NewErrorResponse creates a new ErrorResponse instance.

type GasEstimateResponse

type GasEstimateResponse struct {
	GasEstimate uint64 `json:"gas_estimate"`
}

GasEstimateResponse defines a response definition for tx gas estimation.
