有考虑加入rpc server 和 rpc client的模板和分层吗

[cpj555]

大佬模板整的挺好的,用这套搞了两应用,正好碰到用户体系的问题可能要拆点服务出去,不知道有没有现成的东西套下

我先给个简单的例子参考着弄吧，不是很复杂。

提示：nunu-layout-micro这个以前写到一半搁置了，还没开源。

定义服务端

internal/server/grpc.go

package server

import (
	"fmt"
	"github.com/spf13/viper"
	"go.uber.org/zap"
	pb "nunu-layout-micro/api/user/v1"
	"nunu-layout-micro/internal/rpc"
	"nunu-layout-micro/pkg/log"
	"nunu-layout-micro/pkg/server/grpc"
)

func NewGRPCServer(
	logger *log.Logger,
	conf *viper.Viper,
	userServer rpc.UserServer,
) *grpc.Server {
	// 创建gRPC服务器
	s := grpc.NewServer(
		logger,
		grpc.WithServerHost(conf.GetString("grpc.host")),
		grpc.WithServerPort(conf.GetInt("grpc.port")),
	)
	logger.Info("grpc server start", zap.String("addr", fmt.Sprintf("%s:%d", conf.GetString("grpc.host"), conf.GetInt("grpc.port"))))

	// 注册GRPC服务
	pb.RegisterUserServiceServer(s, userServer)
	return s
}

internal/rpc/rpc.go

package rpc

import "nunu-layout-micro/pkg/log"

type RpcServer struct {
	logger *log.Logger
}

func NewRpcServer(logger *log.Logger) *RpcServer {
	return &RpcServer{
		logger: logger,
	}
}

internal/rpc/user.go

package rpc

import (
	"context"
	pb "nunu-layout-micro/api/user/v1"
	"nunu-layout-micro/internal/service"
)

type UserServer interface {
	Register(context.Context, *pb.RegisterRequest) (*pb.RegisterResponse, error)
	Login(context.Context, *pb.LoginRequest) (*pb.LoginResponse, error)
	UpdateProfile(context.Context, *pb.UpdateProfileRequest) (*pb.UpdateProfileResponse, error)
	GetProfile(context.Context, *pb.GetProfileRequest) (*pb.GetProfileResponse, error)
}

func NewUserServer(rpc *RpcServer, userService service.UserService) UserServer {
	return &userServer{
		userService: userService,
		RpcServer:   rpc,
	}
}

type userServer struct {
	userService service.UserService
	*RpcServer
}

func (s userServer) Register(ctx context.Context, request *pb.RegisterRequest) (*pb.RegisterResponse, error) {
	return s.userService.Register(ctx, request)
}

func (s userServer) Login(ctx context.Context, request *pb.LoginRequest) (*pb.LoginResponse, error) {
	return s.userService.Login(ctx, request)
}

func (s userServer) UpdateProfile(ctx context.Context, request *pb.UpdateProfileRequest) (*pb.UpdateProfileResponse, error) {
	//TODO implement me
	panic("implement me")
}

func (s userServer) GetProfile(ctx context.Context, request *pb.GetProfileRequest) (*pb.GetProfileResponse, error) {
	return s.userService.GetProfile(ctx, request)
}

定义客户端

internal/repository/repository.go

package repository

import (
	"context"
	polaris "github.com/polarismesh/grpc-go-polaris"
	"github.com/spf13/viper"
	"google.golang.org/grpc"
	"google.golang.org/grpc/credentials/insecure"
	pb "nunu-layout-micro/api/user/v1"
	"nunu-layout-micro/pkg/log"
)

type Repository struct {
	logger  *log.Logger
	userCli pb.UserServiceClient
}

func NewRepository(logger *log.Logger, userCli pb.UserServiceClient) *Repository {
	return &Repository{
		logger:  logger,
		userCli: userCli,
	}
}
func NewUserServiceClient(conf *viper.Viper, logger *log.Logger) (pb.UserServiceClient, func(), error) {
	// grpc客户端连接获取
	// 使用 grpc-go-polaris 提供的 DialContext 即可
        // polaris 是腾讯开源的一个服务治理框架，不使用它也可以，直接正常写原生grpc即可
	ctx, cancel := context.WithCancel(context.Background())
	defer cancel()
	conn, err := polaris.DialContext(ctx, "polaris://QuickStartEchoServerGRPC",
		polaris.WithGRPCDialOptions(grpc.WithTransportCredentials(insecure.NewCredentials())),
		polaris.WithDisableRouter(),
	)
	if err != nil {
		logger.Sugar().Fatalf("Failed to dial gRPC service: %v", err)
	}
	return pb.NewUserServiceClient(conn), func() {
		cancel()
	}, nil
}

internal/repository/user.go

package repository

import (
	"context"
	pb "nunu-layout-micro/api/user/v1"
)

type UserRepository interface {
	Register(ctx context.Context, in *pb.RegisterRequest) (*pb.RegisterResponse, error)
	Login(ctx context.Context, in *pb.LoginRequest) (*pb.LoginResponse, error)
	UpdateProfile(ctx context.Context, in *pb.UpdateProfileRequest) (*pb.UpdateProfileResponse, error)
	GetProfile(ctx context.Context, in *pb.GetProfileRequest) (*pb.GetProfileResponse, error)
}

func NewUserRepository(r *Repository) UserRepository {
	return &userRepository{
		Repository: r,
	}
}

type userRepository struct {
	*Repository
}

func (u userRepository) Register(ctx context.Context, in *pb.RegisterRequest) (*pb.RegisterResponse, error) {
	return u.userCli.Register(ctx, in)
}

func (u userRepository) Login(ctx context.Context, in *pb.LoginRequest) (*pb.LoginResponse, error) {
	return u.userCli.Login(ctx, in)
}

func (u userRepository) UpdateProfile(ctx context.Context, in *pb.UpdateProfileRequest) (*pb.UpdateProfileResponse, error) {
	return u.userCli.UpdateProfile(ctx, in)
}

func (u userRepository) GetProfile(ctx context.Context, in *pb.GetProfileRequest) (*pb.GetProfileResponse, error) {
	return u.userCli.GetProfile(ctx, in)
}

总是报mustEmbedUnimplementedrvServer

非常期待大佬能把grpc的部分也单开一个仓库

等我空闲下来吧，其实grpc自己加进去很简单的

好的，这个模板是我所见过的最标准的了。感谢开源开发者
