func NewService

func NewService(config Config, sup Support) *service

NewService创建新的发现服务实例

Types

type AccessControlSupport

type AccessControlSupport interface {
	//合格返回给定对等方是否有资格接收
	//service from the discovery service for a given channel
	EligibleForService(channel string, data common2.SignedData) error
}

访问控制支持检查客户是否有资格接受服务

}

config定义发现服务的配置

func (Config) String

func (c Config) String() string

string返回此配置的字符串表示形式

type ConfigSequenceSupport

type ConfigSequenceSupport interface {
	//configSequence返回给定通道的配置序列
	ConfigSequence(channel string) uint64
}

configSequenceSupport返回给定通道的配置序列

type ConfigSupport

type ConfigSupport interface {
	//config返回通道的配置
	Config(channel string) (*discprotos.ConfigResult, error)
}

配置支持提供对通道配置的访问

type EndorsementSupport

type EndorsementSupport interface {
	//PeersforElement返回给定对等方、通道和链码集的认可描述符
	PeersForEndorsement(channel common.ChainID, interest *discprotos.ChaincodeInterest) (*discprotos.EndorsementDescriptor, error)

	//PeersAuthorizedByCriteria returns the peers of the channel that are authorized by the given chaincode interest
	//这是考虑到，如果感兴趣的链码安装在对等端上，并且
	//考虑到对等端是否是链码集合的一部分。
	//如果传递了零利息或空利息，则不进行过滤。
	PeersAuthorizedByCriteria(chainID common.ChainID, interest *discprotos.ChaincodeInterest) (discovery.Members, error)
}

	//对等方返回被认为是活动的网络成员
	Peers() discovery.Members

	//IdentityInfo返回有关对等方的标识信息
	IdentityInfo() api.PeerIdentitySet
}
