Functions ¶
func ExtractChannelHeaderCertHash ¶
ExtractChannelHeaderCertHash extracts the TLS cert hash from a channel header.
Types ¶
type Chain ¶
type Chain interface { // Sequence returns the current config sequence number, can be used to detect config changes Sequence() uint64 // PolicyManager returns the current policy manager as specified by the chain configuration PolicyManager() policies.Manager // Reader returns the chain Reader for the chain Reader() blockledger.Reader // Errored returns a channel which closes when the backing consenter has errored Errored() <-chan struct{} }
Chain encapsulates chain operations and data.
type ChainManager ¶
ChainManager provides a way for the Handler to look up the Chain.
type Filtered ¶
type Filtered interface {
IsFiltered() bool
}
Filtered is a marker interface that indicates a response sender is configured to send filtered blocks Note: this is replaced by "data_type" label. Keep it for now until we decide how to take care of compatibility issue.
type Handler ¶
type Handler struct { ExpirationCheckFunc func(identityBytes []byte) time.Time ChainManager ChainManager TimeWindow time.Duration BindingInspector Inspector Metrics *Metrics }
Handler handles server requests.
func NewHandler ¶
func NewHandler(cm ChainManager, timeWindow time.Duration, mutualTLS bool, metrics *Metrics, expirationCheckDisabled bool) *Handler
NewHandler creates an implementation of the Handler interface.
type InspectorFunc ¶
The InspectorFunc is an adapter that allows the use of an ordinary function as an Inspector.
type PolicyChecker ¶
PolicyChecker checks the envelope against the policy logic supplied by the function.
type PolicyCheckerFunc ¶
The PolicyCheckerFunc is an adapter that allows the use of an ordinary function as a PolicyChecker.
func (PolicyCheckerFunc) CheckPolicy ¶
func (pcf PolicyCheckerFunc) CheckPolicy(envelope *cb.Envelope, channelID string) error
CheckPolicy calls pcf(envelope, channelID)
type ResponseSender ¶
type ResponseSender interface { // SendStatusResponse sends completion status to the client. SendStatusResponse(status cb.Status) error // SendBlockResponse sends the block and optionally private data to the client. SendBlockResponse(data *cb.Block, channelID string, chain Chain, signedData *protoutil.SignedData) error // DataType returns the data type sent by the sender DataType() string }
ResponseSender defines the interface a handler must implement to send responses.
type Server ¶
type Server struct { Receiver PolicyChecker ResponseSender }
Server is a polymorphic structure to support generalization of this handler to be able to deliver different type of responses.
