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
<?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'] : '';

// 判断APP是否需要加密

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) {

$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();
