leaf 和cocos creator 遊戲實戰（二）註冊與登陸

mongodb的安裝及配置，參考下文：

https://blog.csdn.net/heshushun/article/details/77776706

proto註冊協議擴充：

1.服務端：

    編譯 lobby.proto 檔案（對此不瞭解？請先閱讀《在 Golang 中使用 Protobuf》一文）得到 lobby.pb.go 檔案,命令如下：
        protoc --go_out=. lobby.proto
將lobby.pb.go 放在LeafServerExample src/msg檔案夾下。

2.用戶端：

    把lobby.proto 複製到LeafServerCocosClient node_modules.bin檔案夾下,把proto檔案編譯成靜態檔案使用:

pbjs -t static-module -w commonjs -o protocol.js lobby.protopbts -o protocol.d.ts protocol.js

把protocol.js 和protocol.d.ts拷貝到LeafServerCocosClient assets\script\protocol檔案夾中.

3.lobby.proto：

syntax = "proto3";package msg;enum Result {    REGISTER_SUCCESS=0;    REGISTER_FAIL=1;    LOGIN_SUCCESS=2;    LOGIN_FAIL=3;}message Test {    string Test = 2;}// 使用者登陸協議message UserLogin  {    string LoginName = 1;   // 使用者名稱    string LoginPW =2;      // 密碼}// 註冊協議message UserRegister {    string LoginName =1;    // 使用者名稱    string LoginPW =2;      // 密碼}// 訊息返回協議message UserResult {    Result RetResult =1;    string ErrorInfo = 2;}// 玩家有角色的情況message UserST {    string UID    =1;       // 帳號ID    string ServerID =2;     // 伺服器ID    string RoleUID  =3;     // 角色UID    string RoleName =4;     // 角色名稱字    string RoleLev =5;      // 角色等級    string Coin  =6;        // 金幣    // 其他的暫時不做定義}

向當前模組（game 模組）註冊 訊息處理函數

func init() {    handler(&msg.UserLogin{}, handleUserLogin)    handler(&msg.UserRegister{}, handleUserRegister)}

處理相關訊息

func handleUserRegister(args []interface{}) {    m := args[0].(*msg.UserRegister)    a := args[1].(gate.Agent)    name :=m.GetLoginName()    pwd :=m.GetLoginPW()    log.Debug("receive UserRegister name=%v", m.GetLoginName())    reg := regexp.MustCompile(`/^[a-zA-Z\d]\w{2,10}[a-zA-Z\d]$/`)    matched := reg.FindString(name)    if(matched!=" "){        log.Debug("UserRegister name is licit", )    }    err := mongodbmgr.Find("game","login",bson.M{"name":name,})    if err == nil {        fmt.Println(err)        log.Debug("UserRegister find in fail", )        retBuf := &msg.UserResult{            RetResult: msg.Result_REGISTER_FAIL,            ErrorInfo:"帳號已存在！",        }        a.WriteMsg(retBuf)    }    err =mongodbmgr.Insert("game","login",bson.M{"name":name,"password":pwd})    if err != nil {        fmt.Println(err)        log.Debug("UserRegister write in fail", )        retBuf := &msg.UserResult{            RetResult: msg.Result_REGISTER_FAIL,            ErrorInfo:"註冊失敗，請稍後再試！",        }        a.WriteMsg(retBuf)    } else{        log.Debug("UserRegister write in success", )        retBuf := &msg.UserResult{            RetResult: msg.Result_REGISTER_SUCCESS,        }        a.WriteMsg(retBuf)    }}

func handleUserLogin(args []interface{}) {    m := args[0].(*msg.UserLogin)    a := args[1].(gate.Agent)    log.Debug("receive UserLogin name=%v", m.GetLoginName())    retBuf := &msg.UserResult{        RetResult: msg.Result_LOGIN_SUCCESS,        ErrorInfo:"登陸失敗，請稍後再試！",    }    a.WriteMsg(retBuf)}
