Pinger - hyperledger fabric chaincode ping extension

Often there is a need to find out if everything is correct with chaincode. To do it we would like to ping CC and know some information.

CCKit provides pinger extension for implementing ping opportunity in Hyperledger Fabric chaincodes. When chaincode will be pinged, you get information about invoker, his certificate and time.

Pinger implemented in two version:

  1. As chaincode handlers
  2. As service, that can be embedded in chaincode, using chaincode-as-service mode

Documentation

Overview

Package pinger contains

  • chaincode methods names {service_name}Chaincode_{method_name}
  • chaincode interface definition {service_name}Chaincode
  • chaincode gateway definition {service_name}}Gateway
  • chaincode service to cckit router registration func

Package pinger is a reverse proxy.

It translates gRPC into RESTful JSON APIs.

Package pinger contains structure and functions for checking chain code accessibility

Functions

func Ping 

func Ping(ctx r.Context) (interface{}, error)

Ping create PingInfo struct with tx creator ID and certificate in PEM format

func RegisterChaincodePingerServiceChaincode 

func RegisterChaincodePingerServiceChaincode(r *cckit_router.Group, cc ChaincodePingerServiceChaincode) error

RegisterChaincodePingerServiceChaincode registers service methods as chaincode router handlers

func RegisterChaincodePingerServiceHandler 

func RegisterChaincodePingerServiceHandler(ctx context.Context, mux *runtime.ServeMux, conn *grpc.ClientConn) error

RegisterChaincodePingerServiceHandler registers the http handlers for service ChaincodePingerService to "mux". The handlers forward requests to the grpc endpoint over "conn".

func RegisterChaincodePingerServiceHandlerClient 

func RegisterChaincodePingerServiceHandlerClient(ctx context.Context, mux *runtime.ServeMux, client ChaincodePingerServiceClient) error

RegisterChaincodePingerServiceHandlerClient registers the http handlers for service ChaincodePingerService to "mux". The handlers forward requests to the grpc endpoint over the given implementation of "ChaincodePingerServiceClient". Note: the gRPC framework executes interceptors within the gRPC handler. If the passed in "ChaincodePingerServiceClient" doesn't go through the normal gRPC flow (creating a gRPC client etc.) then it will be up to the passed in "ChaincodePingerServiceClient" to call the correct interceptors.

func RegisterChaincodePingerServiceHandlerFromEndpoint 

func RegisterChaincodePingerServiceHandlerFromEndpoint(ctx context.Context, mux *runtime.ServeMux, endpoint string, opts []grpc.DialOption) (err error)

RegisterChaincodePingerServiceHandlerFromEndpoint is same as RegisterChaincodePingerServiceHandler but automatically dials to "endpoint" and closes the connection when "ctx" gets done.

func RegisterChaincodePingerServiceHandlerServer 

func RegisterChaincodePingerServiceHandlerServer(ctx context.Context, mux *runtime.ServeMux, server ChaincodePingerServiceServer) error

RegisterChaincodePingerServiceHandlerServer registers the http handlers for service ChaincodePingerService to "mux". UnaryRPC :call ChaincodePingerServiceServer directly. StreamingRPC :currently unsupported pending https://github.com/grpc/grpc-go/issues/906. Note that using this registration option will cause many gRPC library features to stop working. Consider using RegisterChaincodePingerServiceHandlerFromEndpoint instead.

func RegisterChaincodePingerServiceServer 

func RegisterChaincodePingerServiceServer(s *grpc.Server, srv ChaincodePingerServiceServer)
