Functions

func ParseHTTPArgs

func ParseHTTPArgs(r *http.Request) (tags []string, page, limit int, err error)

ParseHTTPArgs parses the request's URL and returns a slice containing all arguments pairs. It separates page and limit used for pagination.

func ParseHTTPArgsWithLimit

func ParseHTTPArgsWithLimit(r *http.Request, defaultLimit int) (tags []string, page, limit int, err error)

ParseHTTPArgsWithLimit parses the request's URL and returns a slice containing all arguments pairs. It separates page and limit used for pagination where a default limit can be provided.

func PostProcessResponse

func PostProcessResponse(w http.ResponseWriter, cliCtx context.CLIContext, resp interface{})

PostProcessResponse performs post processing for a REST response. The result returned to clients will contain two fields, the height at which the resource was queried at and the original result.

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 ReturnNotFoundIfNoContent

func ReturnNotFoundIfNoContent(w http.ResponseWriter, data []byte, message string) bool

ReturnNotFoundIfNoContent returns not found error if no content

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 CommitTxProof

type CommitTxProof struct {
	Vote  string `json:"vote"`
	Sigs  string `json:"sigs"`
	Tx    string `json:"tx"`
	Proof string `json:"proof"`
}

CommitTxProof commit tx proof

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.

type ResponseWithHeight

type ResponseWithHeight struct {
	Height int64           `json:"height"`
	Result json.RawMessage `json:"result"`
}

ResponseWithHeight defines a response object type that wraps an original response with a height.

func NewResponseWithHeight

func NewResponseWithHeight(height int64, result json.RawMessage) ResponseWithHeight

NewResponseWithHeight creates a new ResponseWithHeight instance

type SideTxProof added in v0.1.7

type SideTxProof struct {
	Sigs string `json:"sigs"`
	Tx   string `json:"tx"`
	Data string `json:"data"`
}

SideTxProof side-tx proof
