Add some options when creating a server:
svr := api.NewServer(new(DemoImpl), server.WithXXX...)
func WithServerBasicInfo(ebi *rpcinfo.EndpointBasicInfo) Option
Set the service infos for server, including ServiceName and customized Tags, customized Tag such as Cluster, IDC, Env, and it is no need to set Method field of EndpointBasicInfo. It is strongly recommended to configure this option, and those infos will be used for service registration.
func WithServiceAddr(addr net.Addr) Option
Set the listen address for server. Default port is 8888, you can reset the port to 9999 like this:
addr, _ := net.ResolveTCPAddr("tcp", "127.0.0.1:9999")
svr := api.NewServer(new(HelloImpl), server.WithServiceAddr(addr))
When local server has multiple IP addresses, you can also use this method to specify them.
func WithMuxTransport() Option
Enable Kitex multiplexing transport feature on the server side. Client side also need to turn on this option, or it won’t work. More
func WithMiddleware(mw endpoint.Middleware) Option
Add a middleware. More
func WithMiddlewareBuilder(mwb endpoint.MiddlewareBuilder, funcName ...string) Option
Add middleware depends on the context passed in by the framework that contains runtime configuration information (the context of non-RPC calls), so that the middleware can take advantage of the framework’s information when initializing.
func WithLimit(lim *limit.Option) Option
Set the throttling threshold, which allows you to set a limit on QPS and the number of connections, which uses a built-in throttling implementation that can be scaled if there is a custom throttling requirement, integrating your own throttling policy via WithConcurrencyLimiter
or WithQPSLimiter
.
func WithReadWriteTimeout(d time.Duration) Option
Set the server-side read and write timeout.
Note: This feature may be changed or removed in subsequent releases.
func WithExitWaitTime(timeout time.Duration) Option
Set the wait time for graceful shutdown of graceful shutdown on the server side.
func WithMaxConnIdleTime(timeout time.Duration) Option
Set the maximum amount of idle time allowed for the server-side connection to the client.
func WithStatsLevel(level stats.Level) Option
Set the stats level for the server. More
These options only works for scenarios where the transport protocol uses gRPC, with some parameter adjustments to gRPC transfers.
func WithGRPCWriteBufferSize(s uint32) Option
WithGRPCWriteBufferSize determines how much data can be batched before doing a write on the wire. The corresponding memory allocation for this buffer will be twice the size to keep syscalls low. The default value for this buffer is 32KB. Zero will disable the write buffer such that each write will be on underlying connection. Note: A Send call may not directly translate to a write. It corresponds to the WriteBufferSize ServerOption of gRPC.
func WithGRPCReadBufferSize(s uint32) Option
WithGRPCReadBufferSize lets you set the size of read buffer, this determines how much data can be read at most for one read syscall. The default value for this buffer is 32KB. Zero will disable read buffer for a connection so data framer can access the underlying conn directly. It corresponds to the ReadBufferSize ServerOption of gRPC.
func WithGRPCInitialWindowSize(s uint32) Option
WithGRPCInitialWindowSize returns a Option that sets window size for stream. The lower bound for window size is 64K and any value smaller than that will be ignored. It corresponds to the InitialWindowSize ServerOption of gRPC.
func WithGRPCInitialConnWindowSize(s uint32) Option
WithGRPCInitialConnWindowSize returns an Option that sets window size for a connection. The lower bound for window size is 64K and any value smaller than that will be ignored. It corresponds to the InitialConnWindowSize ServerOption of gRPC.
func WithGRPCKeepaliveParams(kp grpc.ServerKeepalive) Option
WithGRPCKeepaliveParams returns an Option that sets keepalive and max-age parameters for the server. It corresponds to the KeepaliveParams ServerOption of gRPC.
func WithGRPCKeepaliveEnforcementPolicy(kep grpc.EnforcementPolicy) Option
WithGRPCKeepaliveEnforcementPolicy returns an Option that sets keepalive enforcement policy for the server. It corresponds to the KeepaliveEnforcementPolicy ServerOption of gRPC.
func WithGRPCMaxConcurrentStreams(n uint32) Option
WithGRPCMaxConcurrentStreams returns an Option that will apply a limit on the number of concurrent streams to each ServerTransport. It corresponds to the MaxConcurrentStreams ServerOption of gRPC.
func WithGRPCMaxHeaderListSize(s uint32) Option
WithGRPCMaxHeaderListSize returns a ServerOption that sets the max (uncompressed) size of header list that the server is prepared to accept. It corresponds to the MaxHeaderListSize ServerOption of gRPC.
func WithSuite(suite Suite) Option
Set up a specific configuration, customize according to the scene, configure multiple options and middlewares combinations and encapsulations in the Suite. More
func WithProxy(p proxy.ReverseProxy) Option
If the server has a proxy, such as Mesh Ingress, you can modify the listening address through this configuration to communicate with the proxy, such as in the proxy. ReverseProxy modifies to the uds address.
func WithRegistryInfo(info *registry.Info) Option
Customize the registration information reported by the service. More
func WithGeneric(g generic.Generic) Option
Specify the generalization call type, which needs to be used in conjunction with the generalization Client/Server. More
func WithErrorHandler(f func(error) error) Option
Set the error handler function, which is executed after the server handler is executed and before the middleware executes.
func WithACLRules(rules ...acl.RejectFunc) Option
Set ACL permission access control, which is executed before service discovery. More
func WithExitSignal(f func() <-chan error) Option
Set the server exit signal. Kitex has a built-in implementation, if you need some customization can be implemented yourself.
func WithReusePort(reuse bool) Option
Set port reuse, that is, whether to enable the underlying TCP port multiplexing mechanism.
func WithRegistry(r registry.Registry) Option
Specify a Registry for service discovery registration reporting. More
func WithTracer(c stats.Tracer) Option
Add an additional Tracer. More
func WithCodec(c remote.Codec) Option
Specify a Codec for scenarios that require custom protocol. More
func WithPayloadCodec(c remote.PayloadCodec) Option
Specifie a PayloadCodec. More
func WithMetaHandler(h remote.MetaHandler) Option
Add a meta handler for customizing transparent information in conjunction with the transport protocol, such as service name, invocation method, machine room, cluster, env, tracerInfo. More
func WithBoundHandler(h remote.BoundHandler) Option
Set IO Bound handlers. More
func WithConcurrencyLimiter(conLimit limiter.ConcurrencyLimiter) Option
Set the concurrency limit for server.
func WithQPSLimiter(qpsLimit limiter.RateLimiter) Option
Set the QPS limit for server.
func WithLimitReporter(r limiter.LimitReporter) Option
Set LimitReporter, and when QPS throttling or connection limiting occurs, you can customize the escalation through LimitReporter.
func WithTransHandlerFactory(f remote.ServerTransHandlerFactory) Option
Set transHandlerFactory. More
func WithTransServerFactory(f remote.TransServerFactory) Option
Set transServerFactory. More
func WithDiagnosisService(ds diagnosis.Service) Option
Set diagnosis service. More
