Overview

Package status defines metadata for errors returned by fabric-sdk-go. This information may be used by SDK users to make decisions about how to handle certain error conditions. Status codes are divided by group, where each group represents a particular component and the codes correspond to those returned by the component. These are defined in detail below.

	Unknown Code = 1

	// ConnectionFailed is returned when a network connection attempt from the SDK fails
	ConnectionFailed Code = 2

	// EndorsementMismatch is returned when there is a mismatch in endorsements received by the SDK
	EndorsementMismatch Code = 3

	// EmptyCert is return when an empty cert is returned
	EmptyCert Code = 4

	// Timeout operation timed out
	Timeout Code = 5

	// NoPeersFound No peers were discovered/configured
	NoPeersFound Code = 6

	// MultipleErrors multiple errors occurred

	MissingEndorsement Code = 9

	// QueryEndorsers error indicates that no endorser group was found that would
	// satisfy the chaincode policy
	QueryEndorsers Code = 11

	// GenericTransient is generally used by tests to indicate that a retry is possible
	GenericTransient Code = 12

	// PrematureChaincodeExecution indicates that an attempt was made to invoke a chaincode that's
	// in the process of being launched.
	PrematureChaincodeExecution Code = 21

	// ChaincodeAlreadyLaunching indicates that an attempt for multiple simultaneous invokes was made to launch chaincode
	ChaincodeAlreadyLaunching Code = 22

	// ChaincodeNameNotFound indicates that an that an attempt was made to invoke a chaincode that's not yet initialized
	ChaincodeNameNotFound Code = 23
)

String representation of the code

func (Code) ToInt32

func (c Code) ToInt32() int32

ToInt32 cast to int32

type Group

type Group int32

Group of status to help users infer status codes from various components

const (
	// UnknownStatus unknown status group
	UnknownStatus Group = iota

	// GRPCTransportStatus is the status associated with requests made over
	// gRPC connections
	GRPCTransportStatus
	// HTTPTransportStatus is the status associated with requests made over HTTP
	// connections
	HTTPTransportStatus

	// EndorserServerStatus status returned by the endorser server
	EndorserServerStatus
	// EventServerStatus status returned by the event service
	EventServerStatus
	// OrdererServerStatus status returned by the ordering service
	OrdererServerStatus
	// FabricCAServerStatus status returned by the Fabric CA server
	FabricCAServerStatus

	// EndorserClientStatus status returned from the endorser client
	EndorserClientStatus
	// OrdererClientStatus status returned from the orderer client
	OrdererClientStatus
	// ClientStatus is a generic client status
	ClientStatus

	// ChaincodeStatus defines the status codes returned by chaincode
	ChaincodeStatus

	// DiscoveryServerStatus status returned by the Discovery Server
	DiscoveryServerStatus

	// TestStatus is used by tests to create retry codes.
	TestStatus
)

func (Group) String

func (g Group) String() string

type Status

type Status struct {
	// Group status group
	Group Group
	// Code status code
	Code int32
	// Message status message
	Message string
	// Details any additional status details
	Details []interface{}
}

Status provides additional information about an unsuccessful operation performed by fabric-sdk-go. Essentially, this object contains metadata about an error returned by the SDK.

func FromError

func FromError(err error) (s *Status, ok bool)

FromError returns a Status representing err if available, otherwise it returns nil, false.

func New

func New(group Group, code int32, msg string, details []interface{}) *Status

New returns a Status with the given parameters

func NewFromExtractedChaincodeError

func NewFromExtractedChaincodeError(code int, message string) *Status

NewFromExtractedChaincodeError returns Status when a chaincode error occurs

func NewFromGRPCStatus

func NewFromGRPCStatus(s *grpcstatus.Status) *Status

NewFromGRPCStatus new Status from gRPC status response

func NewFromProposalResponse

func NewFromProposalResponse(res *pb.ProposalResponse, endorser string) *Status

NewFromProposalResponse creates a status created from the given ProposalResponse

func (*Status) Error

func (s *Status) Error() string
