判定 app 是否需要加密:通过 app 表中的 status 字段来判定,加密的字符串为 app 表中的 key 字段。
在获取的客户端和服务器端(数据库表中相应字段)的版本号不一致时,返回 data['is_upload'] = 1 提示是否升级;一致时返回 data['is_upload'] = 0 不提示升级。
common.php 中 getApp 方法可以添加缓存(静态/Redis等)缓存。
common.php 处理接口公共业务
<?php /** * 处理接口公共业务 */ require_once('./response.php'); require_once('./db.php'); class Common { public $params; public $app; public function check() { $this->params['app_id'] = $appId = isset($_POST['app_id']) ? $_POST['app_id'] : ''; $this->params['version_id'] = $versionId = isset($_POST['version_id']) ? $_POST['version_id'] : ''; $this->params['version_mini'] = $versionMini = isset($_POST['version_mini']) ? $_POST['version_mini'] : ''; $this->params['did'] = $did = isset($_POST['did']) ? $_POST['did'] : ''; $this->params['encrypt_did'] = $encryptDid = isset($_POST['encrypt_did']) ? $_POST['encrypt_did'] : ''; if(!is_numeric($appId) || !is_numeric($versionId)) { return Response::show(401, '参数不合法'); } // 判断APP是否需要加密 $this->app = $this->getApp($appId); if(!$this->app) { return Response::show(402, 'app_id不存在'); } if($this->app['is_encryption'] && $encryptDid != md5($did . $this->app['key'])) { return Response::show(403, '没有该权限'); } } public function getApp($id) { $sql = "select * from `app` where id = " . $id ." and status = 1 limit 1"; $connect = Db::getInstance()->connect(); $result = mysql_query($sql, $connect); return mysql_fetch_assoc($result); } public function getversionUpgrade($appId) { $sql = "select * from `version_upgrade` where app_id = " . $appId ." and status = 1 limit 1"; $connect = Db::getInstance()->connect(); $result = mysql_query($sql, $connect); return mysql_fetch_assoc($result); } /** * 根据图片大小组装相应图片 * @param string $imageUrl * @param string $size */ public function setImage($imageUrl, $size) { if(!$imageUrl) { return ''; } if(!$size) { return $imageUrl; } $type = substr($imageUrl, strrpos($imageUrl, '.')); if(!$type) { return ''; } $path = substr($imageUrl, 0, strrpos($imageUrl, '.')); return $path .

init.php 处理版本升级
<?php require_once('./common.php'); class Init extends Common { public function index() { $this->check(); // 获取版本升级信息 $versionUpgrade = $this->getversionUpgrade($this->app['id']); if($versionUpgrade) { if($versionUpgrade['type'] && $this->params['version_id'] < $versionUpgrade['version_id']) { $versionUpgrade['is_upload'] = $versionUpgrade['type']; }else { $versionUpgrade['is_upload'] = 0; } return Response::show(200, '版本升级信息获取成功', $versionUpgrade); } else { return Response::show(400, '版本升级信息获取失败'); } } } $init = new Init(); $init->index();
