PHP 开发 APP 接口 学习笔记与总结 - APP 接口实例 [6] 版本升级接口开发

时间：2023-03-08 17:07:45

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 . '_' . $size . $type;

    }

}

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();
