群控系统服务端开发模式-应用开发-上传工厂开发

        现在的文件、图片等上传基本都在使用oss存储。而现在常用的oss存储有阿里云、腾讯云、七牛云、华为云等，但是用的最多的还是前三种。而我主要封装的是本地存储、阿里云存储、腾讯云存储、七牛云存储。废话不多说，直接上传设计图及说明，就一目了然咯。     

一、上传父抽象类开发

        在根目录下extend文件夹里创建文件夹并命名为Upload，然后创建上传父抽象类文件并命名为UploadHandle。切记，本类里一定要加上abstract关键字，不仅要类加上，方法也要加上。代码如下：

<?php
/*** 上传父抽象类* User: 龙哥 三年风水* Date: 2024/11/2/0002* Time: 17:47*/
namespace Upload;
abstract class UploadHandle
{/*** 上传操作* @ param $object 加密后的文件* @ param $filePath 临时存放的文件路径* @ return mixed*/abstract function uploadFile($object, $filePath);/*** 删除操作* @ param $object 具体的文件地址* @ return mixed*/abstract function deleteFile($object);
}

二、上传文件工厂控制类

        在根目录下extend文件夹里创建文件夹并命名为Upload，然后创建上传文件工厂控制类并命名为UploadFactory。代码如下：

<?php
/*** 上传文件工厂控制类* User: 龙哥 三年风水* Date: 2024/11/2/0002* Time: 18:06*/
namespace Upload;
use Error\BaseError;
use app\model\param\Upload as UploadModel;
use Upload\channel\LocalUpload;
use Upload\channel\AliyunUpload;
use Upload\channel\TencentUpload;
use Upload\channel\QiniuyunUpload;
class UploadFactory
{public static $instance=null;//缓存实例protected $uploadType = 0;通道类型protected $channel = [];//通道参数/*** 初始化* User: 龙哥·三年风水* Date: 2024/4/8* Time: 15:26* UploadFactory constructor.*/public function __construct($channel){$res = UploadModel::dataFind(['id' => 1],'upload_type,example_name,access_key,secret_key,bucket_name,domain_name');if(empty($res))throw new BaseError("上传通道参数未配置",50000,200);$this->uploadType = $res['upload_type'];if($this->uploadType != 1){$this->channel = ["name"          =>  $res['example_name'],"access_key"    =>  $res['access_key'],"secret_key"    =>  $res['secret_key'],"bucket"        =>  $res['bucket_name'],"domain_name"   =>  $res['domain_name']];}}/*** 调用上传通道* @ return null|AliyunUpload|LocalUpload|QiniuyunUpload|TencentUpload*/public function getUploadHandle(){switch ((int)$this->uploadType){case 1:self::$instance = new LocalUpload();break;case 2:self::$instance = new AliyunUpload($this->channel);break;case 3:self::$instance = new TencentUpload($this->channel);break;case 4:self::$instance = new QiniuyunUpload($this->channel);break;default:self::$instance = null;throw new BaseError("未设置任何文件上传通道",50000,200);break;}return self::$instance;}
}

三、提前说明

        其实这个上传文件工厂控制类还是可以优化的，可以改成自动识别上传工厂类，不需要使用switch方法。明天将实现四个上传工厂类。
