Functions

func GetParam

func GetParam(r *http.Request, param string) string

func GetParamByteSlice

func GetParamByteSlice(r *http.Request, param string) ([]byte, error)

func GetParamFloat64

func GetParamFloat64(r *http.Request, param string) (float64, error)

func GetParamInt32

func GetParamInt32(r *http.Request, param string) (int32, error)

func GetParamInt64

func GetParamInt64(r *http.Request, param string) (int64, error)

func GetParamRegexp

func GetParamRegexp(r *http.Request, param string, re *regexp.Regexp) (string, error)

func GetParamUint

func GetParamUint(r *http.Request, param string) (uint, error)

func GetParamUint64

func GetParamUint64(r *http.Request, param string) (uint64, error)

func RecoverAndLogHandler

func RecoverAndLogHandler(handler http.Handler, logger *logging.Logger) http.Handler

Wraps an HTTP handler, adding error logging. If the inner function panics, the outer function recovers, logs, sends an HTTP 500 error response.

func RegisterRPCFuncs

func RegisterRPCFuncs(mux *http.ServeMux, funcMap map[string]*RPCFunc, logger *logging.Logger)

RegisterRPCFuncs adds a route for each function in the funcMap, as well as general jsonrpc and websocket handlers for all functions. "result" is the interface on which the result objects are registered, and is popualted with every RPCResponse

func StartHTTPServer

func StartHTTPServer(listener net.Listener, handler http.Handler, logger *logging.Logger) (*http.Server, error)

func WriteRPCResponseHTTP

func WriteRPCResponseHTTP(w http.ResponseWriter, res types.RPCResponse)

Types

type RPCFunc

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

RPCFunc contains the introspected type information for a function

func NewRPCFunc

func NewRPCFunc(f interface{}, args string) *RPCFunc

NewRPCFunc wraps a function for introspection. f is the function, args are comma separated argument names

func NewWSRPCFunc

func NewWSRPCFunc(f interface{}, args string) *RPCFunc

NewWSRPCFunc wraps a function for introspection and use in the websockets.

type ResponseWriterWrapper

type ResponseWriterWrapper struct {
	Status int
	http.ResponseWriter
}

Remember the status for logging

func (*ResponseWriterWrapper) Hijack

implements http.Hijacker

func (*ResponseWriterWrapper) WriteHeader

func (w *ResponseWriterWrapper) WriteHeader(status int)
