Types

type Hooks 

type Hooks []func()

Hooks is a collection of func.

type InvokeCaller 

type InvokeCaller interface {
	Call(invoke.Message) error
}

InvokeCaller is the abstraction for invoker call.

type Invoker

	RegisterService(svcInfo *serviceinfo.ServiceInfo, handler interface{}, opts ...RegisterOption) error
	Init() (err error)
	InvokeCaller
}

Invoker is the abstraction for invoker.

func NewInvoker 

func NewInvoker(opts ...Option) Invoker

NewInvoker creates new Invoker.

type Option 

type Option = internal_server.Option

Option is the only way to config server.

func WithCodec(c remote.Codec) Option

WithCodec to set a codec that handle other protocols which not support by kitex

func WithCompatibleMiddlewareForUnary added in v0.9.0 

func WithCompatibleMiddlewareForUnary() Option

WithCompatibleMiddlewareForUnary allows Unary APIs to use the same middleware as non-streaming APIs For thrift unary APIs over HTTP2, it's enabled by default. For grpc(protobuf) streaming, it's disabled by default for backward compatibility, and can be enabled manually. With this option, the req/resp passed to the middleware are the real args and result; For Unary APIs requests, recv/send middlewares will be skipped (still effective for other streaming API requests)

func WithConcurrencyLimiter deprecated added in v0.3.2 

func WithConcurrencyLimiter(conLimit limiter.ConcurrencyLimiter) Option

Deprecated: Use WithConnectionLimiter instead.

func WithConnectionLimiter added in v0.3.3

WithConnectionLimiter sets the limiter of connections. If both WithLimit and WithConnectionLimiter are called, only the latter will take effect.

func WithContextBackup added in v0.7.0 

func WithContextBackup(enable, async bool) Option

WithContextBackup enables local-session to backup kitex server's context, in case of user don't correctly pass context into next RPC call.

  • enable means enable context backup
  • async means backup session will propagate to children goroutines, otherwise it only works on the same goroutine handler

func WithDiagnosisService 

func WithDiagnosisService(ds diagnosis.Service) Option

WithDiagnosisService sets the diagnosis service for gathering debug information.

func WithEnableContextTimeout added in v0.9.0 

func WithEnableContextTimeout(enable bool) Option

WithEnableContextTimeout enables handler timeout. Available since Kitex >= v0.9.0 If enabled, a timeout middleware will be added to the beginning of the middleware chain. The timeout value will be read from RPCInfo.Config().RPCTimeout(), which can be set by a custom MetaHandler NOTE: If there's an error (excluding BizStatusError) returned by server handler or any middleware, cancel will be called automatically.

For an opensource Kitex user, TTHeader has builtin support of timeout-passing (not enabled by default):

  • Client side: add the following NewClient options for enabling TTHeader and setting the timeout to TTHeader client.WithTransportProtocol(transport.TTHeader), client.WithMetaHandler(transmeta.ClientTTHeaderHandler),
  • Server side: add the following NewServer options for reading from TTHeader and enable timeout control server.WithMetaHandler(transmeta.ServerTTHeaderHandler) server.WithEnableContextTimeout(true)

For requests on GRPC transport, a deadline will be added to the context if the header 'grpc-timeout' is positive, so there's no need to use this option.
