func CcCalls

func CcCalls(ccNames ...string) []*discovery.ChaincodeCall

CcCalls creates an array of ChaincodeCalls based of cc names, can be used in AddPeersQuery(CcCalls(...))

func CcInterests

func CcInterests(invocationsChains ...[]*discovery.ChaincodeCall) []*discovery.ChaincodeInterest

CcInterests creates an array of ChaincodeInterests based of ChaincodeCalls, can be used in AddEndorsersQuery(CcInterests(CcCalls(...)))

func GetProperties

func GetProperties(endpoint *discclient.Peer) fab.Properties

GetProperties extracts the properties from the discovered peer.


type Client

type Client interface {
	Send(ctx context.Context, req *Request, targets ...fab.PeerConfig) (<-chan Response, error)

Client gives ability to send discovery request to multiple targets. There are cases when multiple targets requested and some of them are hanging, recommended to cancel ctx after first successful response. Note: "access denied" is a success response, so check for it after response evaluation.

func New

func New(ctx fabcontext.Client) (Client, error)

New returns a new Discover client

type MockDiscoverEndpointResponse

type MockDiscoverEndpointResponse struct {
	Target        string
	PeerEndpoints []*mocks.MockDiscoveryPeerEndpoint
	Error         error
	EndorsersErr  error

MockDiscoverEndpointResponse contains a mock response for the discover client

func (*MockDiscoverEndpointResponse) Build

Build builds a mock discovery response

type MockDiscoveryClient

type MockDiscoveryClient struct {
	// contains filtered or unexported fields

MockDiscoveryClient implements a mock Discover service

func NewMockDiscoveryClient

func NewMockDiscoveryClient() *MockDiscoveryClient

NewMockDiscoveryClient returns a new mock Discover service

func (*MockDiscoveryClient) Send

func (m *MockDiscoveryClient) Send(ctx context.Context, req *Request, targets ...fab.PeerConfig) (<-chan Response, error)

Send sends a Discovery request

func (*MockDiscoveryClient) SetResponses

func (m *MockDiscoveryClient) SetResponses(responses ...MockResponseBuilder)

SetResponses sets the responses that the mock client should return from the Send function

type MockResponseBuilder

type MockResponseBuilder interface {
	Build() Response

MockResponseBuilder builds a mock discovery response

type Request

type Request struct {
	// contains filtered or unexported fields

Request aggregates several queries inside it

func NewRequest

func NewRequest() *Request

NewRequest creates a new request

func (*Request) AddConfigQuery

func (req *Request) AddConfigQuery() *Request

AddConfigQuery adds to the request a config query

func (*Request) AddEndorsersQuery

func (req *Request) AddEndorsersQuery(interests ...*discovery.ChaincodeInterest) (*Request, error)

AddEndorsersQuery adds to the request a query for given chaincodes interests are the chaincode interests that the client wants to query for. All interests for a given channel should be supplied in an aggregated slice

func (*Request) AddLocalPeersQuery

func (req *Request) AddLocalPeersQuery() *Request

AddLocalPeersQuery adds to the request a local peer query

func (*Request) AddPeersQuery

func (req *Request) AddPeersQuery(invocationChain ...*discovery.ChaincodeCall) *Request

AddPeersQuery adds to the request a peer query

func (*Request) OfChannel

func (req *Request) OfChannel(ch string) *Request

OfChannel sets the next queries added to be in the given channel's context
