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;
    }
}
