go-zero docker-compose 搭建课件服务（五）：完善user服务

0.1源码地址

github.com/liuyuede123/go-zero-cou...

1、生成model

到项目根目录下创建model目录，并新建user.sql

mkdir user/rpc/model
touch user/rpc/model/user.sql
CREATE TABLE `user`
(
    `id`          bigint unsigned NOT NULL AUTO_INCREMENT,
    `login_name`  varchar(255) NOT NULL DEFAULT '' COMMENT '登录名',
    `username`        varchar(255) NOT NULL DEFAULT '' COMMENT '用户姓名',
    `sex`      tinyint(3) unsigned NOT NULL DEFAULT '0' COMMENT '用户性别',
    `password`    varchar(255) NOT NULL DEFAULT '' COMMENT '用户密码',
    `is_delete`   tinyint(4) NOT NULL DEFAULT 0 COMMENT '是否删除 0-未删除 1-已删除',
    `create_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
    `update_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
    PRIMARY KEY (`id`),
    UNIQUE KEY `udx_login_name` (`login_name`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8mb4;

到model目录下生成model

cd user/rpc/model
goctl model mysql ddl -src="./*.sql" -dir="./" -c

2、生成rpc文件

到user/rpc目录下生成rpc文件

goctl rpc protoc user.proto --go_out=. --go-grpc_out=. --zrpc_out=.

3、增加mysql配置

user目录下初始化module

go mod init
go mod tidy

user/rpc/etc/user.yaml中增加数据源和缓存配置

Name: user.rpc
ListenOn: 127.0.0.1:8300
Etcd: 
  Hosts: 
  - etcd:2379 
  Key: user.rpc

# mysql数据源
Mysql: 
  DataSource: root:liufutian@tcp(192.168.0.110:3306)/go_zero_courseware?charset=utf8mb4&parseTime=true&loc=Asia%2FShanghai

# redis缓存
CacheRedis: 
  - Host: 192.168.0.110:6379 
    Pass:

修改user/rpc/internal/config/config.go中配置

package config

import (
    "github.com/zeromicro/go-zero/core/stores/cache" 
    "github.com/zeromicro/go-zero/zrpc"
)

type Config struct {
    zrpc.RpcServerConf

    Mysql struct {
        DataSource string
    }

    CacheRedis cache.CacheConf
}

修改courseware/rpc/internal/svc/servicecontext.go相关配置

package svc

import (
    "github.com/zeromicro/go-zero/core/stores/sqlx" 
    "go-zero-courseware/user/rpc/internal/config" 
    "go-zero-courseware/user/rpc/model"
)

type ServiceContext struct {
    Config config.Config

    UserModel model.UserModel
}

func NewServiceContext(c config.Config) *ServiceContext {
    conn := sqlx.NewMysql(c.Mysql.DataSource)
    return &ServiceContext{
        Config: c,
        UserModel: model.NewUserModel(conn, c.CacheRedis),
    }
}

4、添加用户逻辑

先走通，后续会优化用户逻辑

user/rpc/internal/logic/registerlogic.go增加注册逻辑

package logic

import (
    "context" 
    "go-zero-courseware/user/rpc/internal/svc" 
    "go-zero-courseware/user/rpc/model" 
    "go-zero-courseware/user/rpc/user" 
    "google.golang.org/grpc/status"

    "github.com/zeromicro/go-zero/core/logx"
)

type RegisterLogic struct {
    ctx    context.Context
    svcCtx *svc.ServiceContext
    logx.Logger
}

func NewRegisterLogic(ctx context.Context, svcCtx *svc.ServiceContext) *RegisterLogic {
    return &RegisterLogic{
        ctx:    ctx,
        svcCtx: svcCtx,
        Logger: logx.WithContext(ctx),
    }
}

func (l *RegisterLogic) Register(in *user.RegisterRequest) (*user.RegisterResponse, error) {
    _, err := l.svcCtx.UserModel.FindOneByLoginName(l.ctx, in.LoginName)
    if err == nil {
        return nil, status.Error(5000, "登录名已存在")
    }

    if err != model.ErrNotFound {
        return nil, status.Error(500, err.Error())
    }
    newUser := model.User{
        LoginName: in.LoginName,
        Username:  in.Username,
        Sex:       in.Sex,
        Password:  in.Password,
    }
    _, err = l.svcCtx.UserModel.Insert(l.ctx, &newUser)
    if err != nil {
        return nil, status.Error(500, err.Error())
    }

    return &user.RegisterResponse{}, nil
}

user/rpc/internal/logic/loginlogic.go增加登录逻辑

package logic

import (
    "context" 
    "go-zero-courseware/user/rpc/model" 
    "google.golang.org/grpc/status"

    "go-zero-courseware/user/rpc/internal/svc" 
    "go-zero-courseware/user/rpc/user"

    "github.com/zeromicro/go-zero/core/logx"
)

type LoginLogic struct {
    ctx    context.Context
    svcCtx *svc.ServiceContext
    logx.Logger
}

func NewLoginLogic(ctx context.Context, svcCtx *svc.ServiceContext) *LoginLogic {
    return &LoginLogic{
        ctx:    ctx,
        svcCtx: svcCtx,
        Logger: logx.WithContext(ctx),
    }
}

func (l *LoginLogic) Login(in *user.LoginRequest) (*user.LoginResponse, error) {
    userInfo, err := l.svcCtx.UserModel.FindOneByLoginName(l.ctx, in.LoginName)
    if err == model.ErrNotFound {
        return nil, status.Error(5000, "用户不存在")
    }
    if err != nil {
        return nil, status.Error(500, err.Error())
    }

    if in.Password != userInfo.Password {
        return nil, status.Error(5000, "密码错误")
    }

    return &user.LoginResponse{
        Id:    userInfo.Id,
        Token: "a.b.c",
    }, nil
}

增加用户信息逻辑

package logic

import (
    "context" 
    "go-zero-courseware/user/rpc/model" 
    "google.golang.org/grpc/status"

    "go-zero-courseware/user/rpc/internal/svc" 
    "go-zero-courseware/user/rpc/user"

    "github.com/zeromicro/go-zero/core/logx"
)

type UserInfoLogic struct {
    ctx    context.Context
    svcCtx *svc.ServiceContext
    logx.Logger
}

func NewUserInfoLogic(ctx context.Context, svcCtx *svc.ServiceContext) *UserInfoLogic {
    return &UserInfoLogic{
        ctx:    ctx,
        svcCtx: svcCtx,
        Logger: logx.WithContext(ctx),
    }
}

func (l *UserInfoLogic) UserInfo(in *user.UserInfoRequest) (*user.UserInfoResponse, error) {
    userInfo, err := l.svcCtx.UserModel.FindOne(l.ctx, in.Id)
    if err == model.ErrNotFound {
        return nil, status.Error(5000, "用户不存在")
    }
    if err != nil {
        return nil, status.Error(500, err.Error())
    }

    return &user.UserInfoResponse{
        Id:        userInfo.Id,
        Username:  userInfo.Username,
        LoginName: userInfo.LoginName,
        Sex:       userInfo.Sex,
    }, nil
}

5、完善api代码

到user/api目录下，生成api端代码

goctl api go -api user.api -dir . -style gozero

user/api/etc/user.yaml配置

Name: user
Host: 0.0.0.0
Port: 8300

UserRpc: 
  Etcd: 
    Hosts: 
      - etcd:2379 
    Key: user.rpc

user/api/internal/config/config.go配置

package config

import (
    "github.com/zeromicro/go-zero/rest" 
    "github.com/zeromicro/go-zero/zrpc"
)

type Config struct {
    rest.RestConf

    UserRpc zrpc.RpcClientConf
}

user/api/internal/svc/servicecontext.go配置

package svc

import (
    "github.com/zeromicro/go-zero/zrpc"

    "go-zero-courseware/user/rpc/userclient"
)

type ServiceContext struct {
    Config config.Config

    UserRpc userclient.User
}

func NewServiceContext(c config.Config) *ServiceContext {
    return &ServiceContext{
        Config:  c,
        UserRpc: userclient.NewUser(zrpc.MustNewClient(c.UserRpc)),
    }
}

user/api/internal/logic/userregisterlogic.go增加注册逻辑

package logic

import (
    "context" 
    "go-zero-courseware/user/rpc/userclient" 
    "google.golang.org/grpc/status"

    "go-zero-courseware/user/api/internal/svc" 
    "go-zero-courseware/user/api/internal/types"

    "github.com/zeromicro/go-zero/core/logx"
)

type UserRegisterLogic struct {
    logx.Logger
    ctx    context.Context
    svcCtx *svc.ServiceContext
}

func NewUserRegisterLogic(ctx context.Context, svcCtx *svc.ServiceContext) *UserRegisterLogic {
    return &UserRegisterLogic{
        Logger: logx.WithContext(ctx),
        ctx:    ctx,
        svcCtx: svcCtx,
    }
}

func (l *UserRegisterLogic) UserRegister(req *types.RegisterRequest) (resp *types.RegisterResponse, err error) {
    _, err = l.svcCtx.UserRpc.Register(l.ctx, &userclient.RegisterRequest{
        LoginName: req.LoginName,
        Username:  req.Username,
        Password:  req.Password,
        Sex:       req.Sex,
    })
    if err != nil {
        return nil, status.Error(500, err.Error())
    }

    return &types.RegisterResponse{}, nil
}

user/api/internal/logic/userloginlogic.go增加登录逻辑

package logic

import (
    "context" 
    "go-zero-courseware/user/rpc/userclient"

    "go-zero-courseware/user/api/internal/svc" 
    "go-zero-courseware/user/api/internal/types"

    "github.com/zeromicro/go-zero/core/logx"
)

type UserLoginLogic struct {
    logx.Logger
    ctx    context.Context
    svcCtx *svc.ServiceContext
}

func NewUserLoginLogic(ctx context.Context, svcCtx *svc.ServiceContext) *UserLoginLogic {
    return &UserLoginLogic{
        Logger: logx.WithContext(ctx),
        ctx:    ctx,
        svcCtx: svcCtx,
    }
}

func (l *UserLoginLogic) UserLogin(req *types.LoginRequest) (resp *types.LoginResponse, err error) {
    login, err := l.svcCtx.UserRpc.Login(l.ctx, &userclient.LoginRequest{
        LoginName: req.LoginName,
        Password:  req.Password,
    })
    if err != nil {
        return nil, err
    }

    return &types.LoginResponse{
        Id:    login.Id,
        Token: login.Token,
    }, nil
}

user/api/internal/logic/userinfologic.go增加用户信息逻辑

package logic

import (
    "context" 
    "go-zero-courseware/user/rpc/userclient" 
    "google.golang.org/grpc/status"

    "go-zero-courseware/user/api/internal/svc" 
    "go-zero-courseware/user/api/internal/types"

    "github.com/zeromicro/go-zero/core/logx"
)

type UserInfoLogic struct {
    logx.Logger
    ctx    context.Context
    svcCtx *svc.ServiceContext
}

func NewUserInfoLogic(ctx context.Context, svcCtx *svc.ServiceContext) *UserInfoLogic {
    return &UserInfoLogic{
        Logger: logx.WithContext(ctx),
        ctx:    ctx,
        svcCtx: svcCtx,
    }
}

func (l *UserInfoLogic) UserInfo(req *types.UserInfoRequest) (resp *types.UserInfoResponse, err error) {
    info, err := l.svcCtx.UserRpc.UserInfo(l.ctx, &userclient.UserInfoRequest{
        Id: req.Id,
    })
    if err != nil {
        return nil, status.Error(500, err.Error())
    }

    return &types.UserInfoResponse{
        Id:        info.Id,
        Username:  info.Username,
        LoginName: info.LoginName,
        Sex:       info.Sex,
    }, nil
}

6、docker-compose增加配置

user/rpc目录下生成rpc的Dockerfile

goctl docker -go user.go

user/api目录下生成api的Dockerfile

goctl docker -go user.go

根目录下docker-compose.yml增加用户服务api和rpc配置

6、运行user服务

user目录下

go mod tidy

到项目根目录

docker-compose up -d

7、测试接口

```json

localhost:8300/api/user/register

{

“loginName”: “liuyuede”,

“username”: “liuyuede”,

“sex”: 1,

“password”: “123”

}

localhost:8300/api/user/login

{

“loginName”: “liuyuede”,

“password”: “123”

}

localhost:8300/api/user/userInfo

{

“id”: 2

}
