描述

首先獲得骰子

? 每天（首次登錄、簽到）之后都可以獲得一個骰子

擲骰子邏輯

獲取前進步數(每次使用全部的骰子，每個骰子可以前進1-6步)，每個步數都有獎勵(前進一步可以獲得10積分，每到達特定步數可以獲得指定金幣獎勵)

?

實現：

首先設置redis緩存

key

鍵類型過期時間描述

date(‘Y-m-d’, time()) . “__” . $uid ."_Login_dice"	string	86400	登陸鎖，來指定首次登陸
date(‘Y-m-d’, time()) . “__” . $uid ."_signIn_dice"	string	86400	簽到鎖，來指定首次登陸
$uid . ‘_diceNum’	string	30*86400	用戶骰子的總數
$uid . ‘_diceStep’	string	30*86400	用戶擲骰子走的步數
$uid._‘rollDiceLock’	string	3	redis防止并發點擊鎖
stepRank	zset	30*86400	用戶步數排行榜

數據表

骰子活動記錄表

CREATE TABLE `activity_score` (`id` int(11) unsigned NOT NULL AUTO_INCREMENT,`uid` int(11) DEFAULT NULL COMMENT '用戶id',`step` int(5) DEFAULT NULL COMMENT '前進的步數',`after_step` int(5) DEFAULT NULL COMMENT '使用之后的步數',`score` int(11) DEFAULT NULL COMMENT '獲取的積分',`coin` int(11) DEFAULT '0' COMMENT '額外金幣獎勵，未獲得則為零',`use_num` int(5) DEFAULT NULL COMMENT '使用的骰子數量',`init_time` int(11) DEFAULT NULL,`last_time` timestamp NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,PRIMARY KEY (`id`),KEY `uid_index` (`uid`) USING BTREE ) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=gbk COMMENT='骰子活動記錄表';

邏輯

? 每次登陸、和簽到獲得骰子放在指定的鍵中，每天首次登陸和簽到自增骰子($uid . ‘_diceNum’)的數量。

? 每次登陸簽到設置鎖,用來判斷用戶是否可以獲得骰子

? 擲骰子的時候獲取用戶的骰子總數減去骰子記錄表中的該用戶指定時間小號的骰子數量就可以獲得剩余的骰子數量，然后計算出用戶可以前進的步數，增加到用戶步數中($uid . ‘_diceStep’),然后將用戶和步數放到用戶步數排行(stepRank)中，將本次骰子的記錄放到骰子記錄表中，將獲得的獎勵存到用戶賬戶中，即可。

使用ci框架在iblog項目中實現具體代碼為：

控制器代碼：

（將邏輯處理全部放到service層代碼，這里只做參數獲取）

class Activity extends Base_Controller {public function __construct(){parent::__construct();$this->load->service('Activity_service');$this->load->model('Activity_model');}//擲骰子操作public function rollDice(){$data = $this->input->post();$uid = empty($data['uid']) ? 0 : $data['uid'];$this->Activity_service->rollDice($uid);}//獲取用戶步數排行榜public function stepRank(){$data = $this->input->post();$uid = empty($data['uid']) ? 0 : $data['uid'];$this->Activity_service->stepRank($uid);}//擲骰子活動首頁public function diceIndex(){$data = $this->input->post();$uid = empty($data['uid']) ? 0 : $data['uid'];$this->Activity_service->diceIndex($uid);} }

登錄和簽到中添加增加骰子方法

/** 用戶簽到 User控制器*/ public function signIn() {$data = $this->input->post();$rules = [['field' => 'user_id','label' => '用戶id','rules' => 'required','errors' => ['require' => '用戶id不能為空',]],];$res = $this->validate($data, $rules);if (!$res) {fail(400, '參數錯誤!');}$data['init_date'] = date('Y-m-d', time());$isSignIn = $this->users_model->isSignIn($data);if ($isSignIn) {fail(400, '已簽到,不可重復簽到!');}//獲取當前用戶昨天簽到的keep_time+1,若沒有則為1;$time = date('Y-m-d', strtotime('-1 days'));$data['keep_time'] = $this->users_model->getSignInKeep($data['user_id'], $time);//簽到操作$data1 = $this->users_model->signIn($data);if (!$data1) {fail(400, '簽到失敗!');}//簽到成功增加一個骰子$this->Activity_service->addDice($data['user_id'],'signIn');success($data, '簽到成功!'); }//登錄 Login控制器 public function login() {//獲取數據$post = $this->input->post();//查詢是否有該用戶名$data = $this->users_model->findByUsername($post['username']);if ($data) {if (encrypt($post['password']) == $data['password']) {//記錄登錄日志$sqlData = ['ip' => $_SERVER['SERVER_ADDR'],'init_time' => time(),'user_name' => $post['username'],'uid' => $data['id']];$data['init_time'] = time();//登錄日志$this->logger_model->userLoginLog($sqlData);//用戶首次登錄成功送一個骰子$this->Activity_service->addDice($data['id'],'Login');$data['image'] = "http://cakephp.com/" . $data['image'];success($data, '登陸成功！');} else {fail(501, '密碼錯誤！');}} else {fail(500, '沒有該用戶！');} }

service代碼：

model層代碼：

這里我定義了一個Base_model里面定義了幾個比較基礎的通用增刪改查方法

<?php /*** Created by PhpStorm.* User: wyq* Date: 2021/10/29* Time: 13:35*/class Activity_model extends Base_Model {public function __construct(){parent::__construct();}public function addScore($uid, $step, $score, $coin, $after_step, $num){$data = ['uid' => $uid,'step' => $step,'score' => $score,'coin' => $coin,'after_step' => $after_step,'use_num' => $num,'init_time' => time()];return $this->commonInsert('activity_score', $data);}public function getUseNum($uid){$res = $this->commonQuery('sum(use_num) num','uid='.$uid,'activity_score');return $res[0]['num'];}public function updateScore($uid, $score,$coin){$before = $this->commonQuery('score,coin', ['id' => $uid], 'users');$score += $before[0]['score'];$coin += $before[0]['coin'];return $this->commonUpdate('users', ['score' => $score,'coin' => $coin], ['id' => $uid]);}public function stepRank($rank){$uid = array_column($rank, 'uid');$res = $this->db->select('id,nickname,image')->where_in('id', $uid)->get('users');return $res->num_rows() ? $res->result_array() : false;} }

Base_model代碼

<?phpclass Base_Model extends CI_Model {public function __construct(){parent::__construct();$this->load->database();}/** 通用的簡單檢索*/public function commonQuery($fields, $where, $table){$query = $this->db->select($fields)->where($where)->get($table);return $query->num_rows() ? $query->result_array() : [];}/** 通用的簡單刪除*/public function commonDelete($table, $where){$this->db->delete($table, $where);return $this->db->affected_rows() ? true : false;}/** 通用的新增*/public function commonInsert($table, $value){$this->db->insert($table, $value);return $this->db->affected_rows() ? true : false;}/** 通用的修改*/public function commonUpdate($table, $value, $where){$this->db->update($table, $value, $where);return $this->db->affected_rows() ? true : false;} }

userInfo.rank	json	用戶排名
userInfo.distance	int	距上一名的步數差，若為沒上榜則距離上榜的步數差
userInfo.num	int	當前用戶可以使用的骰子數

這里因為本系統中沒有額外的道具，所以獎勵只能有用戶的積分，和金幣。若其他系統額外的獎勵可以是其他的道具，基本功能可以實現，但是功能還不是很完善。
