go-zero微服务入门教程

本教程主要模拟实现用户注册和用户信息查询两个接口。

准备工作

安装基础环境

安装etcd， mysql，redis，建议采用docker安装。

MySQL安装好之后，新建数据库dsms_admin，并新建表sys_user，建表语句见后文。

安装插件

这里采用GoLand开发工具，请自行搜索安装插件Goctl。

修改API Gateway代码调用rpc服务

admin-api.yaml

修改配置文件admin-api.yaml，增加如下内容，这里的192.168.2.204为基础环境服务器IP。

Timeout: 60000Mysql:Datasource: root:123456@tcp(192.168.2.204:3306)/dsms_admin?charset=utf8mb4&parseTime=true&loc=Asia%2FShanghaiCacheRedis:- Host: 192.168.2.204:6379Pass: qkgxChxNkCwKType: nodeRedis:Address: 192.168.2.204:6379Pass: qkgxChxNkCwKSysRpc:Timeout: 30000Etcd:Hosts:- 192.168.2.204:2379Key: sysa.rpc

通过etcd自动去发现可用的rpc服务。

config.go

修改api/internal/config/config.go如下，增加rpc服务依赖。

	SysRpc zrpc.RpcClientConfCacheRedis cache.ClusterConfRedis struct {Address stringPass    string}Mysql struct {Datasource string}

servicecontext.go

修改api/internal/svc/servicecontext.go，如下：

type ServiceContext struct {Config config.ConfigSys   sys.SysRedis *redis.Redis
}func NewServiceContext(c config.Config) *ServiceContext {newRedis := redis.New(c.Redis.Address, redisConfig(c))return &ServiceContext{Config: c,Sys:    sys.NewSys(zrpc.MustNewClient(c.SysRpc, zrpc.WithUnaryClientInterceptor(interceptor))),Redis:  newRedis,}
}func redisConfig(c config.Config) redis.Option {return func(r *redis.Redis) {r.Type = redis.NodeTyper.Pass = c.Redis.Pass}
}func interceptor(ctx context.Context, method string, req any, reply any, cc *grpc.ClientConn, invoker grpc.UnaryInvoker, opts ...grpc.CallOption) error {md := metadata.New(map[string]string{"x": "xx"})ctx = metadata.NewOutgoingContext(ctx, md)// logx.Debug("调用rpc服务前")err := invoker(ctx, method, req, reply, cc)if err != nil {return err}// logx.Debug("调用rpc服务后")return nil
}

通过ServiceContext在不同业务逻辑之间传递依赖。

useraddlogic.go

修改api/internal/logic/useraddlogic.go里的UserAdd方法，如下：

func (l *UserAddLogic) UserAdd(req *types.AddUserReq) (resp *types.AddUserResp, err error) {res, err := l.svcCtx.Sys.UserAdd(l.ctx, &sysclient.UserAddReq{Name:     req.Name,NickName: req.NickName,Password: req.Password,Email:    req.Email,RoleId:   req.RoleId,Status:   req.Status,//CreateBy: l.ctx.Value(cache.JwtFieldUserName).(string),CreateBy: "songfayuan",})if err != nil {reqJson, _ := json.Marshal(req)logx.WithContext(l.ctx).Errorf("添加用户信息失败，请求参数：%s，异常信息：%s", reqJson, err.Error())return nil, rpcerror.New(err)}return &types.AddUserResp{Code:    200,Message: "添加用户成功",Data:    types.ReceiptUserData{Id: res.Id},}, nil
}

userinfologic.go

修改api/internal/logic/userinfologic.go里的UserInfo方法，如下：


func (l *UserInfoLogic) UserInfo() (*types.UserInfoResp, error) {//这里的key和生成jwt token时传入的key一致//userId, _ := l.ctx.Value(cache.JwtFieldUserId).(json.Number).Int64()var userId int64 = 1resp, err := l.svcCtx.Sys.UserInfo(l.ctx, &sysclient.InfoReq{UserId: userId,})if err != nil {logx.WithContext(l.ctx).Errorf("根据userId：%s, 查询用户异常：%s", strconv.FormatInt(userId, 10), err.Error())return nil, rpcerror.New(err)}var MenuTree []*types.ListMenuTree//组装ant ui中的菜单for _, item := range resp.MenuListTree {MenuTree = append(MenuTree, &types.ListMenuTree{Id:       item.Id,Path:     item.Path,Name:     item.Name,ParentId: item.ParentId,Icon:     item.Icon,})}if MenuTree == nil {MenuTree = make([]*types.ListMenuTree, 0)}//组装element ui中的菜单var MenuTreeVue []*types.ListMenuTreeVuefor _, item := range resp.MenuListTree {if len(strings.TrimSpace(item.VuePath)) != 0 {MenuTreeVue = append(MenuTreeVue, &types.ListMenuTreeVue{Id:           item.Id,ParentId:     item.ParentId,Title:        item.Name,Path:         item.VuePath,Name:         item.Name,Icon:         item.VueIcon,VueRedirent:  item.VueRedirect,VueComponent: item.VueComponent,Meta: types.MenuTreeMeta{Title: item.Name,Icon:  item.VueIcon,},})}}if MenuTreeVue == nil {MenuTreeVue = make([]*types.ListMenuTreeVue, 0)}err = l.svcCtx.Redis.Set(strconv.FormatInt(userId, 10), strings.Join(resp.BackgroundUrls, ","))if err != nil {logx.Errorf("设置用户：%s, 权限到Redis异常：%+v", resp.Name, err)}return &types.UserInfoResp{Code:    200,Message: "成功",Data: types.UserInfoData{Avatar:      resp.Avatar,Name:        resp.Name,MenuTree:    MenuTree,MenuTreeVue: MenuTreeVue,ResetPwd:    resp.ResetPwd,},}, nil
}

定义数据库表结构，并生成CRUD代码

在rpc目录下创建model/sysmodel目录，在rpc目录下创建doc/sql/sys目录。

在这里插入图片描述

创建sys_user.sql

在rpc/doc/sql/sys目录下编写sql文件sys_user.sql，如下：

-- goctl model mysql ddl -src doc/sql/sys/sys_user.sql -dir ./model/sysmodel-- ----------------------------
-- Table structure for sys_user
-- ----------------------------
DROP TABLE IF EXISTS `sys_user`;
CREATE TABLE `sys_user`
(`id`          bigint(20) NOT NULL AUTO_INCREMENT COMMENT '编号',`name`        varchar(128) NOT NULL DEFAULT '' COMMENT '账号',`nick_name`   varchar(128) NOT NULL DEFAULT '' COMMENT '名称',`avatar`      varchar(255) NOT NULL DEFAULT '' COMMENT '头像',`password`    varchar(128) NOT NULL DEFAULT '' COMMENT '密码',`salt`        varchar(40)  NOT NULL DEFAULT '' COMMENT '加密盐',`email`       varchar(128) NOT NULL DEFAULT '' COMMENT '邮箱',`mobile`      varchar(32)  NOT NULL DEFAULT '' COMMENT '手机号',`status`      tinyint(4) NOT NULL DEFAULT '1' COMMENT '状态  -1：禁用   1：正常',`create_by`   varchar(128) NOT NULL DEFAULT '' COMMENT '创建人',`create_time` timestamp    NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',`update_by`   varchar(128) NOT NULL DEFAULT '' COMMENT '更新人',`update_time` datetime     NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',`del_flag`    tinyint(4) unsigned NOT NULL DEFAULT '0' COMMENT '是否删除  1：已删除  0：正常',PRIMARY KEY (`id`),KEY           `name` (`name`) USING BTREE
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='用户管理';
-- ----------------------------
-- Records of sys_user
-- ----------------------------
INSERT INTO `sys_user` VALUES (1, 'admin', 'admin', '', '$2a$10$hDlSis2/3IPGNYQhFlFfK.Wmi7iH9/jr6wcN.5c.rh7fc/uUnCo4S', '', 'admin@dsms.com', '13612345678', 1, 'admin', '2018-08-14 11:11:11', '', '2023-01-04 10:17:30', 0);
