用户是如何登录的？

简介

skynet_fly_demo在账号上采用了传统的账号密码方式。

流程

1. c2s 用户调用loginserver的登录接口
2. s2s loginserver 调用 centerserver 验证账号，密码
3. s2s loginserver 调用 hallserver 生成token
4. s2c loginserver 返回登录结果和token
5. c2s 连接大厅服，发送登录请求，hallserver验证token
6. s2c hallserver 回复登录结果

流程1

涉及skynet_fly技术

* http server 
* cluster rpc

涉及服务

* loginserver
* centerserver

客户端通过http方式调用user/login接口进行注册,客户端传递账号，密码,之后loginserver rpc 调用centerserver 进行登录验证。

--登录
local function login(c)
    local req = c.req
    local body = req.body
    local account = body.account
    local password = body.password
    assert(account, "not account")
    assert(password, "not passwword")

    local isok, errcode, errmsg = rpc_center_account.auth(account, password)
    if not isok then
        rsp_body.set_rsp(c, nil, errcode, errmsg)
    else
        local player_id, hall_server_id = errcode, errmsg
        local host = rpc_hall_player.get_host(player_id)
        assert(host, "can`t get host")
        local token = rpc_hall_player.create_token(player_id, ENUM.LOGIN_TOKEN_TIME_OUT)
        assert(type(token) == "string", "create token err ")
        rsp_body.set_rsp(c, {
            token = token,
            host = host,
            player_id = player_id,
        })
    end
end

流程2

涉及skynet_fly技术

* cluster rpc
* orm

涉及服务

* loginserver
* centerserver

调用rpc_center_account.auth(account, password) 到centerserver 验证账号密码。

--验证登录
function CMD.auth(account, password)
    local orm_clinet = get_orm_by_account(account)
    local account_info = orm_clinet:get_one_entry(account)
    if not account_info then
        return nil, CODE.NOT_USER, "NOT_USER"
    end

    password = crypt_util.HMAC.SHA256(password, crypt.base64decode(account_info.key))
    if account_info.password ~= password then
        return nil, CODE.ERR_PASSWORD, "ERR_PASSWORD"
    end
    --log.info("auth >>>>> :", account_info)
    account_info.last_login_time = time_util.time()
    orm_clinet:change_save_one_entry(account_info)
    return true, account_info.player_id, account_info.hall_server_id
end

--注册
function M.register(account_info, channel) 
    local cli = frpc_client:instance("centerserver", "account_m")
    cli:set_mod_num(sbyte(account_info.account, account_info.account:len()))
    local ret = cli:one_mod_call("register", account_info, channel)
    if not ret then return end

    return table.unpack(ret.result)
end

成功后，进入到流程3通知大厅服为该玩家创建登录的token。

流程3

涉及skynet_fly技术

* cluster rpc

涉及服务

* loginserver
* hallserver

通过rpc_hall_player.create_token(player_id, ENUM.LOGIN_TOKEN_TIME_OUT)调用得到token

流程4

涉及skynet_fly技术

* cluster rpc

把得到的token返回给客户端。

流程5

涉及skynet_fly技术

* ws gate

客户端拿到hallserver的连接host和token通过ws 建立连接，进行登录，hallserver收到登录消息，进去token验证

流程6

验证通过返回登录成功
