PHP 开发 APP 接口--版本升级接口

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

init.php 处理版本升级

<?phprequire_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;}retu Response::show(200, '版本升级信息获取成功', $versionUpgrade);} else {retu Response::show(400, '版本升级信息获取失败');}}}$init = new Init();$init->index();
