kitex单server多service调用

单server多service怎么添加注册中心?

报错

{"level":"error","ts":1725794886.8642902,"msg":"service discovery error: no instance remains for ucenter"}

server代码

// 服务注册
	addr, _ := net.ResolveTCPAddr("tcp", config.ServerAddr)

	retryConfig := retry.NewRetryConfig(
		retry.WithMaxAttemptTimes(10),
		retry.WithObserveDelay(20*time.Second),
		retry.WithRetryDelay(5*time.Second),
	)

	r, err := etcd.NewEtcdRegistryWithRetry([]string{config.EtcdAddr}, retryConfig) // r 不能重复使用.
	if err != nil {
		panic(err)
	}

	svr := server.NewServer(server.WithServerBasicInfo(&rpcinfo.EndpointBasicInfo{ServiceName: config.ServerName}), server.WithRegistry(r), server.WithServiceAddr(addr), server.WithSuite(suite), server.WithRefuseTrafficWithoutServiceName())

	err = login.RegisterService(svr, handler.NewLoginImpl())
	if err != nil {
		panic(err)
	}

	err = register.RegisterService(svr, handler.NewRegisterImpl())
	if err != nil {
		panic(err)
	}

	err = svr.Run()
	if err != nil {
		panic(err)
	}

client代码

var loginCli login.Client

func initLogin() {
	r, err := etcd.NewEtcdResolver([]string{config.EtcdAddr})
	if err != nil {
		panic(err)
	}
	loginCli, err = login.NewClient(config.ServerName, client.WithResolver(r), client.WithTransportProtocol(transport.GRPC), client.WithMetaHandler(transmeta.ClientHTTP2Handler))

	if err != nil {
		panic(err)
	}
}

看官方示例

好像客户端的代码得写出每个service的服务名称

clienta := servicea.MustNewClient("servicea", client.WithTransportProtocol(transport.GRPC), client.WithHostPorts("127.0.0.1:8888"))
clientb := serviceb.MustNewClient("serviceb", client.WithTransportProtocol(transport.GRPC), client.WithHostPorts("127.0.0.1:8888"))

所以想问加注册中心客户端该怎么调用?

这个文档好像只提供了单server单service的调用案例?

服务注册时以server为粒度的，再多service也只是一个server

我服务端注册的server的服务名是ucenter, 然后etcd也有相应的key, 但是客户端的调用使用ucenter为服务名显示调用失败(no instance remains for ucenter), 检查了key键也没有错, 后面看了官方的某个调用,好像是要service的每个服务名

试了一下单service调用,好像也不行,那应该不是service的问题

调没成功是因为这个#42, 升级下版本就好了
另外client调用要加transport.TTHeader跟transmeta.ClientTTHeaderHandler这两个参数

	registerCli, err = register.NewClient(config.ServerName, client.WithResolver(r), client.WithTransportProtocol(transport.TTHeader), client.WithMetaHandler(transmeta.ClientTTHeaderHandler))
