Constants

const (
	FreePortAddress = ":0" // FreePortAddress marks the server listens using random free port.

)

Variables

var (
	Ctx      = modCtx{}      // Ctx is instance of module Context, which manages the context feature.
	Balancer = modBalancer{} // Balancer is instance of module Balancer, which manages the load balancer features.
	Resolver = modResolver{} // Resolver is instance of module Resolver, which manages the DNS resolving for client.
	Client   = modClient{}   // Client is instance of module Client, which manages the client features.
	Server   = modServer{}   // Server is instance of module Server, which manages the server feature.
)

Types

type GrpcServer

type GrpcServer struct {
	Server *grpc.Server
	// contains filtered or unexported fields
}

GrpcServer is the server for GRPC protocol.

func (*GrpcServer) GetConfig

func (s *GrpcServer) GetConfig() *GrpcServerConfig

GetConfig returns the configuration of current Server.

func (*GrpcServer) GetListenedAddress

func (s *GrpcServer) GetListenedAddress() string

GetListenedAddress retrieves and returns the address string which are listened by current server.

func (*GrpcServer) GetListenedPort

func (s *GrpcServer) GetListenedPort() int

GetListenedPort retrieves and returns one port which is listened to by current server.

func (*GrpcServer) Logger

func (s *GrpcServer) Logger() *glog.Logger

Logger is alias of GetLogger.

func (*GrpcServer) Run

func (s *GrpcServer) Run()

Run starts the server in blocking way.

func (*GrpcServer) Service

func (s *GrpcServer) Service(services ...gsvc.Service)

Service binds service list to current server. Server will automatically register the service list after it starts.

func (*GrpcServer) Start

func (s *GrpcServer) Start()

Start starts the server in no-blocking way.

func (*GrpcServer) Stop

func (s *GrpcServer) Stop()

Stop gracefully stops the server.

func (*GrpcServer) UnaryLogger

func (s *GrpcServer) UnaryLogger(
	ctx context.Context, req interface{}, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler,
) (interface{}, error)

UnaryLogger is the default unary interceptor for logging purpose.

func (*GrpcServer) Wait

func (s *GrpcServer) Wait()

Wait works with Start, which blocks current goroutine until the server stops.

type GrpcServerConfig

type GrpcServerConfig struct {
	Address          string              // (optional) Single address for server listening, use `:0` or `ip:0` to serve random port.
	Name             string              // (optional) Name for current service.
	Logger           *glog.Logger        // (optional) Logger for server.
	LogPath          string              // (optional) LogPath specifies the directory for storing logging files.
	LogStdout        bool                // (optional) LogStdout specifies whether printing logging content to stdout.
	ErrorStack       bool                // (optional) ErrorStack specifies whether logging stack information when error.
	ErrorLogEnabled  bool                // (optional) ErrorLogEnabled enables error logging content to files.
	ErrorLogPattern  string              // (optional) ErrorLogPattern specifies the error log file pattern like: error-{Ymd}.log
	AccessLogEnabled bool                // (optional) AccessLogEnabled enables access logging content to file.
	AccessLogPattern string              // (optional) AccessLogPattern specifies the error log file pattern like: access-{Ymd}.log
	Endpoints        []string            // (optional) Endpoints are custom endpoints for service register, it uses Address if empty.
	Options          []grpc.ServerOption // (optional) GRPC Server options.
}

GrpcServerConfig is the configuration for server.

func (*GrpcServerConfig) MustSetWithMap

func (c *GrpcServerConfig) MustSetWithMap(m g.Map)

MustSetWithMap acts as SetWithMap but panics if error occurs.

func (*GrpcServerConfig) SetWithMap

func (c *GrpcServerConfig) SetWithMap(m g.Map) error

SetWithMap changes current configuration with map. This is commonly used for changing several configurations of current object.

type Service

type Service struct {
	gsvc.Service
	Endpoints gsvc.Endpoints
}

Service implements gsvc.Service interface.
