Function Errorf

httpgrpc/httpgrpc.go:122–124

Errorf returns a HTTP gRPC error that is correctly forwarded over gRPC, and can eventually be converted back to a HTTP response with HTTPResponseFromError.

(code int, tmpl string, args ...interface{})

// gRPC, and can eventually be converted back to a HTTP response with
// HTTPResponseFromError.
func Errorf(code int, tmpl string, args ...interface{}) error {
	return Error(code, fmt.Sprintf(tmpl, args...))
}

// ErrorFromHTTPResponse converts an HTTP response into a grpc error, and uses HTTP response body as an error message.
// Note that if HTTP response body contains non-utf8 string, then returned error cannot be marshalled by protobuf.
