服务注册扩展
Kitex 支持自定义注册模块,使用者可自行扩展集成其他注册中心,该扩展定义在 pkg/registry 下。
扩展接口和 Info 定义
- 扩展接口
// Registry is extension interface of service registry.
type Registry interface {
Register(info *Info) error
Deregister(info *Info) error
}
- Info 定义 Kitex 定义了部分注册信息,使用者也可以根据需要自行扩展注册信息到 Tags 中。
// Info is used for registry.
// The fields are just suggested, which is used depends on design.
type Info struct {
// ServiceName will be set in kitex by default
ServiceName string
// Addr will be set in kitex by default
Addr net.Addr
// PayloadCodec will be set in kitex by default, like thrift, protobuf
PayloadCodec string
Weight int
StartTime time.Time
WarmUp time.Duration
// extend other infos with Tags.
Tags map[string]string
}
集成到 Kitex
通过 option 指定自己的注册模块和自定义的注册信息。注意注册需要服务信息,服务信息也是通过 option 指定。
-
指定服务信息
option:
WithServerBasicInfo
ebi := &rpcinfo.EndpointBasicInfo{ ServiceName: "yourServiceName", Tags: make(map[string]string), } ebi.Tags[idc] = "xxx" svr := xxxservice.NewServer(handler, server.WithServerBasicInfo(ebi))
-
指定自定义注册模块
option:
WithRegistry
svr := xxxservice.NewServer(handler, server.WithServerBasicInfo(ebi), server.WithRegistry(yourRegistry))
-
自定义 RegistryInfo
Kitex 默认赋值 ServiceName、Addr 和 PayloadCodec,若需要其他注册信息需要使用者自行注入。option:
WithRegistryInfo
svr := xxxservice.NewServer(handler, server.WithRegistry(yourRegistry), server.WithRegistryInfo(yourRegistryInfo))
