|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
### 启动服务
|
||||
- 调试模式下 工具VSCode 配置 .vscode\launch.json
|
||||
```shell
|
||||
{
|
||||
// 使用 IntelliSense 了解相关属性。
|
||||
// 悬停以查看现有属性的描述。
|
||||
// 欲了解更多信息,请访问: https://go.microsoft.com/fwlink/?linkid=830387
|
||||
"version": "0.2.0",
|
||||
"configurations": [
|
||||
{
|
||||
"name": "gateway_1",
|
||||
"type": "go",
|
||||
"request": "launch",
|
||||
"mode": "debug",
|
||||
"program": "${workspaceFolder}/services/gateway", //配置Go项目启动文件路径,即main函数所在的.go文件的路径,${workspaceRoot}代表项目的根目录,也就是 /bin /pkg /src这三个文件夹所在的目录
|
||||
"args": ["-conf","./conf/gateway_1.yaml"], //指定服务启动的依赖配置文件 配置文件默认放在bin/conf 目录下
|
||||
"cwd": "${workspaceFolder}/bin", //设置工作目录
|
||||
"internalConsoleOptions": "openOnSessionStart",
|
||||
"output": "${workspaceFolder}/bin/vsdebug_gateway", //设置vscode调试时生成文件的路径
|
||||
"showGlobalVariables": true,
|
||||
"env": {}, //可以用来配置调试启动时所用的环境变量参数,比如gopath临时设置为某个参数就可以在这里指定,如果有多个gopath,用英文冒号:来连接多个gopath
|
||||
},
|
||||
{
|
||||
"name": "worker_1",
|
||||
"type": "go",
|
||||
"request": "launch",
|
||||
"mode": "debug",
|
||||
"program": "${workspaceFolder}/services/worker", //配置Go项目启动文件路径,即main函数所在的.go文件的路径,${workspaceRoot}代表项目的根目录,也就是 /bin /pkg /src这三个文件夹所在的目录
|
||||
"args": ["-conf","./conf/worker_1.yaml"], //指定服务启动的依赖配置文件
|
||||
"cwd": "${workspaceFolder}/bin", //设置工作目录
|
||||
"internalConsoleOptions": "openOnSessionStart",
|
||||
"output": "${workspaceFolder}/bin/vsdebug_worker", //设置vscode调试时生成文件的路径
|
||||
"showGlobalVariables": true,
|
||||
"env": {}, //可以用来配置调试启动时所用的环境变量参数,比如gopath临时设置为某个参数就可以在这里指定,如果有多个gopath,用英文冒号:来连接多个gopath
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
- 编译启动 执行 linux-build.bat 文件 生成执行文件 暂时只编译了linux版本的执行文件
|
||||
```
|
||||
cd ./bin
|
||||
./gateway -conf ./conf/gateway_1.yaml
|
||||
```
|
||||
|
||||
### 如何快速开发模块
|
||||
- 定义模块类型名称 在comm/core.go 中定义定义自己的业务模块名称
|
||||
```go
|
||||
const (
|
||||
SM_GateModule core.M_Modules = "gateway" //gate模块 网关服务模块
|
||||
SM_WebModule core.M_Modules = "web" //web模块
|
||||
SM_UserModule core.M_Modules = "user" //用户模块
|
||||
SM_PackModule core.M_Modules = "pack" //背包模块
|
||||
SM_MailModule core.M_Modules = "mail" //邮件模块
|
||||
SM_FriendModule core.M_Modules = "friend" //好友模块
|
||||
//定义自己的模块名称
|
||||
)
|
||||
```
|
||||
- 创建自己的模块目录 在modules/ 目录下创建自己的模块目录
|
||||
- 定义自己的模块对象 在modules/自己的模块目录 创建module.go 文件
|
||||
```go
|
||||
package pack //修改成自己的包名
|
||||
|
||||
import (
|
||||
"go_dreamfactory/comm"
|
||||
"go_dreamfactory/modules"
|
||||
|
||||
"go_dreamfactory/lego/core"
|
||||
)
|
||||
|
||||
/*
|
||||
模块名:Pack
|
||||
描述:背包系统模块
|
||||
开发:李伟
|
||||
*/
|
||||
func NewModule() core.IModule {
|
||||
m := new(Pack)
|
||||
return m
|
||||
}
|
||||
|
||||
//换成自己的模块对象
|
||||
type Pack struct {
|
||||
modules.ModuleBase
|
||||
}
|
||||
|
||||
func (this *Pack) GetType() core.M_Modules {
|
||||
return comm.SM_PackModule //换成自己的模块名
|
||||
}
|
||||
|
||||
//组装组件的地方
|
||||
func (this *Pack) OnInstallComp() {
|
||||
this.ModuleBase.OnInstallComp()
|
||||
}
|
||||
|
||||
```
|
||||
- 定义自己的用户请求处理组件 在modules/自己的模块目录 创建api_comp.go 文件 名字根据自己的情况定义,
|
||||
```go
|
||||
//api_comp.go
|
||||
//必须继承 modules.MComp_GateComp
|
||||
type Api_Comp struct {
|
||||
modules.MComp_GateComp
|
||||
}
|
||||
|
||||
//定义具体的消息处理函数
|
||||
func (this *Api_Comp) QueryUserPackReq(ctx context.Context, session comm.IUserSession, req *pb.QueryUserPackReq) (err error) {
|
||||
|
||||
}
|
||||
|
||||
|
||||
|
||||
//将组件装备到模块上
|
||||
//module.go
|
||||
func (this *Pack) OnInstallComp() {
|
||||
this.ModuleBase.OnInstallComp()
|
||||
this.api_comp = this.RegisterComp(new(Api_Comp)).(*Api_Comp)
|
||||
}
|
||||
```
|
||||
- 定义自己的协议 在pb/proto 下定义自己的proto协议文件,并将文件加入到pb_2.7.py编译工具中
|
||||
```py
|
||||
buildProto('./pb/proto','./pb','comm')
|
||||
buildProto('./pb/proto','./pb','errorcode')
|
||||
buildProto('./pb/proto','./pb','user_db')
|
||||
buildProto('./pb/proto','./pb','user_msg')
|
||||
buildProto('./pb/proto','./pb','pack_db')
|
||||
buildProto('./pb/proto','./pb','pack_msg')
|
||||
//加入知己的协议文件
|
||||
```
|
||||
- 将模块装备到worker服务容器中 services/worker/main.go
|
||||
```go
|
||||
func main() {
|
||||
flag.Parse()
|
||||
s := NewService(
|
||||
rpcx.SetConfPath(*conf),
|
||||
rpcx.SetVersion("1.0.0.0"),
|
||||
)
|
||||
s.OnInstallComp( //装备组件
|
||||
services.NewGateRouteComp(),
|
||||
)
|
||||
lego.Run(s, //运行模块
|
||||
// web.NewModule(),
|
||||
user.NewModule(),
|
||||
pack.NewModule(),
|
||||
mail.NewModule(),
|
||||
//在这里吧自己的模块注册进去
|
||||
)
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
### 服务容器的定义说明
|
||||
- service 容器定义 项目可更具情况组合拆分业务到具体的服务中
|
||||
```go
|
||||
var (
|
||||
conf = flag.String("conf", "./conf/worker.yaml", "获取需要启动的服务配置文件") //启动服务的Id
|
||||
)
|
||||
|
||||
func main() {
|
||||
flag.Parse()
|
||||
s := NewService(
|
||||
rpcx.SetConfPath(*conf), //指定配置文件路径
|
||||
rpcx.SetVersion("1.0.0.0"), //设置服务版本号
|
||||
)
|
||||
//每一个服务都只是一个进程容器,服务提供的功能业务取决服务绑定了哪些组件和模块
|
||||
s.OnInstallComp( //装备组件
|
||||
services.NewGateRouteComp(), //装备接收用户消息的组件
|
||||
)
|
||||
lego.Run(s, //装备模块
|
||||
user.NewModule(), //装备用户模块
|
||||
pack.NewModule(), //装备背包模块
|
||||
mail.NewModule(), //装备邮件模块
|
||||
)
|
||||
|
||||
}
|
||||
|
||||
func NewService(ops ...rpcx.Option) core.IService {
|
||||
s := new(Service)
|
||||
s.Configure(ops...)
|
||||
return s
|
||||
}
|
||||
|
||||
//继承基础服务对象 方便后期通用接口的扩展
|
||||
type Service struct {
|
||||
services.ServiceBase
|
||||
}
|
||||
|
||||
//初始化服务中需要用到的系统工具
|
||||
func (this *Service) InitSys() {
|
||||
this.ServiceBase.InitSys()
|
||||
//初始化缓存系统
|
||||
if err := cache.OnInit(this.GetSettings().Sys["cache"]); err != nil {
|
||||
panic(fmt.Sprintf("init sys.cache err: %s", err.Error()))
|
||||
} else {
|
||||
log.Infof("init sys.cache success!")
|
||||
}
|
||||
//初始化存储系统
|
||||
if err := db.OnInit(this.GetSettings().Sys["db"]); err != nil {
|
||||
panic(fmt.Sprintf("init sys.db err: %s", err.Error()))
|
||||
} else {
|
||||
log.Infof("init sys.db success!")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 模块容器的定义说明
|
||||
pack/module.go 每个模块目录必须有一个模块对象 一般将相同类型的业务分为一个模块中实现, 模块也只是一个容器,模块中具体实现功能的单元为模块组件对象,模块启动是装备具体的业务组件集合实现相关的业务功能
|
||||
```go
|
||||
func NewModule() core.IModule {
|
||||
m := new(Pack)
|
||||
return m
|
||||
}
|
||||
|
||||
//模块结构对象 继承基础模块对象
|
||||
type Pack struct {
|
||||
modules.ModuleBase
|
||||
api_comp *Api_Comp
|
||||
configure_comp *Configure_Comp
|
||||
}
|
||||
|
||||
//模块类型确定 模块名称
|
||||
func (this *Pack) GetType() core.M_Modules {
|
||||
return comm.SM_PackModule
|
||||
}
|
||||
//服务启动相关模块时调用的接口
|
||||
func (this *Pack) Init(service core.IService, module core.IModule, options core.IModuleOptions) (err error) {
|
||||
err = this.ModuleBase.Init(service, module, options)
|
||||
return
|
||||
}
|
||||
//模块启动时装备业务组件 可更具自己的业务划分 自己定义业务组件
|
||||
func (this *Pack) OnInstallComp() {
|
||||
this.ModuleBase.OnInstallComp()
|
||||
//用户背包相关协议处理组件
|
||||
this.api_comp = this.RegisterComp(new(Api_Comp)).(*Api_Comp)
|
||||
//背包系统的相关配置管理组件
|
||||
this.configure_comp = this.RegisterComp(new(Configure_Comp)).(*Configure_Comp)
|
||||
}
|
||||
```
|
||||
pack/api_comp.go 背包用户api组件 用于接收处理用具背包请求协议
|
||||
```go
|
||||
//Api 组件继承于模块网关组件 modules.MComp_GateComp 内部通过反射机制将当前组件内处理协议的接口注册到 comp_gateroute.go 网关服务组件中,之后服务组件就可以把接收到的用户消息分发给当前api组件
|
||||
type Api_Comp struct {
|
||||
modules.MComp_GateComp
|
||||
module *Pack
|
||||
}
|
||||
//每个组件都可以通过组件初始化接口拿到 当前服务容器对象以及所属的模块对象
|
||||
func (this *Api_Comp) Init(service core.IService, module core.IModule, comp core.IModuleComp, options core.IModuleOptions) (err error) {
|
||||
this.MComp_GateComp.Init(service, module, comp, options)
|
||||
this.module = module.(*Pack)
|
||||
return
|
||||
}
|
||||
|
||||
///查询用户背包数据 处理用处的消息接口 统一 func(ctx context.Context, session comm.IUserSession, req 消息结构对象)(err error)/////ctx 上下文控制器 可以管理方法调用中生成的多个协程 以及传递一些元数据
|
||||
//session 用户的会话对象 可以使用此对象给用户发送消息以及关闭用户的连接对象
|
||||
//req 协议处理函数接收到具体消息数据对象
|
||||
func (this *Api_Comp) QueryUserPackReq(ctx context.Context, session comm.IUserSession, req *pb.QueryUserPackReq) (err error) {
|
||||
var (
|
||||
code pb.ErrorCode
|
||||
pack *pb.DB_UserPackData
|
||||
grids []*pb.DB_GridData
|
||||
)
|
||||
defer func() {
|
||||
session.SendMsg(string(this.module.GetType()), "queryuserpackresp", code, &pb.QueryUserPackResp{Grids: grids})
|
||||
}()
|
||||
if !session.IsLogin() {
|
||||
code = pb.ErrorCode_NoLogin
|
||||
return
|
||||
}
|
||||
//通过缓存读取到用户的背包信息
|
||||
if pack, err = cache.Defsys.Pack_QueryUserPack(session.GetUserId()); err != nil {
|
||||
log.Errorf("QueryUserPackReq err:%v", err)
|
||||
code = pb.ErrorCode_CacheReadError
|
||||
return
|
||||
} else {
|
||||
grids = this.module.configure_comp.GetPackItemByType(pack, req.IType)
|
||||
}
|
||||
return
|
||||
}
|
||||
```
|
||||
|
||||
### 客户端发送消息到服务器处理的流程介绍
|
||||
- 前后端通用协议结构定义 pb/proto/comm.proto
|
||||
```go
|
||||
message UserMessage {
|
||||
string MainType =1; //消息的主id 默认为具体的业务模块名称
|
||||
string SubType = 2; //消息的副id 默认为具体处理消息的函数名
|
||||
ErrorCode Code = 3; //服务端回应客户端返回的错误码 pb/proto/errorcode.proto 定义
|
||||
bytes Data = 4; //具体的消息体内容
|
||||
}
|
||||
```
|
||||
- 网关服务接收用户协议的处理 modules/gateway/agent.go
|
||||
```go
|
||||
//用户代理对象
|
||||
type Agent struct {
|
||||
gateway IGateway
|
||||
wsConn *websocket.Conn
|
||||
sessionId string
|
||||
uId string
|
||||
writeChan chan *pb.UserMessage
|
||||
closeSignal chan bool
|
||||
state int32 //状态 0 关闭 1 运行 2 关闭中
|
||||
wg sync.WaitGroup
|
||||
}
|
||||
|
||||
//读取用户发送过来的消息
|
||||
func (this *Agent) readLoop() {
|
||||
defer this.wg.Done()
|
||||
var (
|
||||
data []byte
|
||||
msg *pb.UserMessage = &pb.UserMessage{}
|
||||
err error
|
||||
)
|
||||
locp:
|
||||
for {
|
||||
if _, data, err = this.wsConn.ReadMessage(); err != nil {
|
||||
log.Errorf("agent:%s uId:%s ReadMessage err:%v", this.sessionId, this.uId, err)
|
||||
go this.Close()
|
||||
break locp
|
||||
}
|
||||
//读取消息 并序列化到 UserMessage 结构对象
|
||||
if err = proto.Unmarshal(data, msg); err != nil {
|
||||
log.Errorf("agent:%s uId:%s Unmarshal err:%v", this.sessionId, this.uId, err)
|

//分发处理用户的消息请求
|
||||
this.messageDistribution(msg)
|
||||
}
|
||||
}
|
||||
log.Debugf("agent:%s uId:%s readLoop end!", this.sessionId, this.uId)
|
||||
}
|
||||
|
||||
//分发用户消息 将用户消息采用负载的方式分到到 worker 类型的服务
|
||||
//此处后期会补充设计用户协议分化系统,暂时采用负载分发实现基本功能线
|
||||
func (this *Agent) messageDistribution(msg *pb.UserMessage) {
|
||||
reply := &pb.RPCMessageReply{}
|
||||
log.Debugf("agent:%s uId:%s MessageDistribution msg:%s.%s", this.sessionId, this.uId, msg.MainType, msg.SubType)
|
||||
if err := this.gateway.Service().RpcCallByType("worker", string(comm.Rpc_GatewayRoute), context.Background(), &pb.AgentMessage{
|
||||
Ip: this.IP(),
|
||||
UserSessionId: this.sessionId,
|
||||
UserId: this.uId,
|
||||
GatewayServiceId: this.gateway.Service().GetId(),
|
||||
Method: fmt.Sprintf("%s.%s", msg.MainType, msg.SubType),
|
||||
Message: msg.Data,
|
||||
}, reply); err != nil {
|
||||
log.Errorf("agent:%s uId:%s MessageDistribution err:%v", this.sessionId, this.uId, err)

|
||||
}
|
||||
}
|
||||
|
||||
```

||||
- Worker 服务如何接受用户的消息 services/comp_gateroute.go
|
||||
```go
|
||||
//网关服务组件启动时会注册Rpc方法 接收网关服务那边发过来的用户消息
|
||||
func (this *SComp_GateRouteComp) Start() (err error) {
|
||||
this.service.RegisterFunctionName(string(comm.Rpc_GatewayRoute), this.ReceiveMsg) //注册网关路由接收接口
|
||||
err = this.ServiceCompBase.Start()
|
||||
return
|
||||
}
|
||||
|
||||
//具体接收用户消息的方法 此处消息分发需要当前服务内有模块注册处理消息的接口 没有注册的话 此处会打印错误日志
|
||||
//msghandles 为消息处理函数的管理对象
|
||||
func (this *SComp_GateRouteComp) ReceiveMsg(ctx context.Context, args *pb.AgentMessage, reply *pb.RPCMessageReply) error {

- 业务模块 如何接受处理用户的消息
|
||||
```go
|
||||
#模块需要接受处理用户发送过来的消息需要装备一个继承modules/gate_comp.go 的模块网关组件,此组件启动是会自动把自身定义的消息处理函数注册到上面提到的服务网关组件services/comp_gateroute.go 中去,实现可以参考pack/api_comp.go 的定义
|
||||
/*
