Yii2.0使用阿里云OSS的SDK上传图片、下载、删除图片 [ 2.0 版本 ]

准备工作：需要使用composer执行命令，如果没有安装composer的需要提前安装，参考文档：[composer安装流程][composer]

本文来自于:[Yii2.0使用阿里云OSS的SDK上传图片、下载、删除图片][Yii2.0_OSS_SDK]

**1、项目目录结构**

我使用的是基础版，只有后台目录，请自行对照自己的项目目录结构，会用到以下的几个目录：

[![目录结构.png][.png]][.png_.png]

**2、在项目根目录下运行cmd命令**

[![根目录.png][.png 1]][.png_.png 1][![根目录cmd.png][cmd.png]][cmd.png_cmd.png]

**3、执行composer命令**

切换到中国国内镜像

composer  config -g repo.packagist composer https://packagist.phpcomposer.com

执行加载SDK命令

composer require aliyuncs/oss-sdk-php

[![执行成功.png][.png 2]][.png_.png 2]

**4、查看根目录/vendor/里面，会增加以下目录文件，说明安装依赖文件成功：** [![阿里云目录.png][.png 3]][.png_.png 3]

**5、在根目录/common/里面新建components目录，新建Aliyunoss.php文件** 需要注意项目的命名空间，引入文件 [![aliyun.php.png][]][aliyun.php.png 1]

**6、根目录/common/components/Aliyunoss.php代码：**

<?php

    namespace common\components;
    
    use Yii;
    use yii\base\Component;
    use OSS\OssClient;
    use OSS\Croe\OssException;
    
    class Aliyunoss extends Component
    {
        public static $oss;
    
        public function __construct()
        {
            parent::__construct();
            $accessKeyId = Yii::$app->params['oss']['accessKeyId'];                 //获取阿里云oss的accessKeyId
            $accessKeySecret = Yii::$app->params['oss']['accessKeySecret'];         //获取阿里云oss的accessKeySecret
            $endpoint = Yii::$app->params['oss']['endPoint'];                       //获取阿里云oss的endPoint
            self::$oss = new OssClient($accessKeyId, $accessKeySecret, $endpoint);  //实例化OssClient对象
        }
    
        /**
         * 使用阿里云oss上传文件
         * @param $object   保存到阿里云oss的文件名
         * @param $filepath 文件在本地的绝对路径
         * @return bool     上传是否成功
         */
        public function upload($object, $filepath)
        {
            // $res = false;
            $bucket = Yii::$app->params['oss']['bucket'];  //获取阿里云oss的bucket
    
            $result=array();
            try{
                $getOssInfo=self::$oss->uploadFile($bucket, $object, $filepath);
                $result['url'] = $getOssInfo['info']['url'];
                if($getOssInfo['info']['url']){
                    @unlink(substr($_path, 1));
                }
            }catch(OssException $e){
                var_dump($e);
                return;
            };
            $url=$result['url'];
            return  $url;
            // var_dump("$url");die();
    
          //     $res = true;
            //     return $url;
        }
    
    
        /**
         * 删除指定文件
         * @param $object 被删除的文件名
         * @return bool   删除是否成功
         */
        public function delete($object)
        {
            $res = false;
            $bucket = Yii::$app->params['oss']['bucket'];    //获取阿里云oss的bucket
            if (self::$oss->deleteObject($bucket, $object)){
            //调用deleteObject方法把服务器文件上传到阿里云oss
                $res = true;
            }
            return $res;
        }
    
    //测试
        public function test(){
            echo 123;
            echo "success";
        }
    }

**7、在根目录/common/config/main.php，添加：**

'Aliyunoss' => [
            'class' => 'common\components\Aliyunoss',
         ],

[![main.png][]][main.png 1]

**8、在根目录/common/config/params.php，添加sdk信息，代码需要自行修改**

'oss' =>[                                          //阿里云OSS
            'ossServer' => 'oss-cn-      .aliyuncs.com', //服务器外网地址，
            'ossServerInternal' => 'oss-cn-     .aliyuncs.com', //服务器内网地址
            'accessKeyId'=>'        ',
            'accessKeySecret'=>'          ',
            'bucket' => '        ',
            'endPoint' => '          ',
        ],

[![params.png][]][params.png 1]

**9、根目录/backend/controllers/控制器名.php，里面引用文件**

//阿里云OSS执行
    use common\components\Aliyunoss;

由于上传图片限制，自此至下面就看代码了

**10、准备上传图片数据，**

public function actionAdd(){
            $img_banner = trim($_FILES['vend_banner']['name']);
            $img_banner = explode('.',$img_banner);
            $imgs_banner = $img_banner[1];
            $img_banner = date('YmdHis').mt_rand(100,1000).md5($img_banner[0]);
            //文件重命名
            $vend_banners = "./images/upload/".$img_banner.'.'.$imgs_banner; 
            $vend_banner = $img_banner.'.'.$imgs_banner;  
          
            $uploadPath = dirname(dirname(__FILE__)).'/web/images/upload/';  // 取得临时文件路径
                if (!file_exists($uploadPath)) {
                    @mkdir($uploadPath, 0777, true);
                }
            $file_Path_vend_banner = $uploadPath.$vend_banner;
            $filepath_vend_banner=str_replace("\\", "/",$file_Path_vend_banner);//绝对路径，上传第二个参数
            $object_vend_banner="data/Company/".$vend_banner;            //拼接存储路径和文件名称，上传第一个参数
            if(is_uploaded_file($_FILES['vend_banner']['tmp_name'])){  //判断是否post上传
                if(!move_uploaded_file($_FILES['vend_banner']['tmp_name'],$vend_banners)){
                    //移动到临时目录里
                    echo 'banner上传失败';exit();
                }
            }
            $vend_banner_url = Yii::$app->Aliyunoss->upload($object_vend_banner,$filepath_vend_banner);
             //调用新建的文件，执行OSS上传，返回的是上传到阿里云的OSS文件路径，打印出来是：
            //string(116) "http:// ******.oss-cn-******.aliyuncs.com/data/Company/20170908124236303cc17c30cd111c7215fc8f51f8790e0e1.jpg"

**11、删除图片**

$oss_url=$data2[0]['vend_banner'];//只要（上传时候的）图片名，
    $object="data/Company/".$oss_url; //将你阿里云的存储路径+图片名=组成数据
    $is_del = Yii::$app->Aliyunoss->delete($object);//删除指定的图片，返回true,否则返回false
