HomeBackend DevelopmentPHP TutorialYii2.0 uses Alibaba Cloud OSS SDK to upload, download, and delete images.

本篇文章主要介绍了Yii2.0使用阿里云OSS的SDK上传图片、下载、删除图片示例,具有一定的参考价值,有兴趣的可以了解一下

之前从没接触过Yii,借助的各方资源来做的这个整合阿里云OSS的SDK上传图片实例,如果有不正之处请指出!
前面参照了weinirumo 的介绍,大家可以自行去查看。

好了,下面开始进入主题:

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

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:

2、在项目根目录下运行cmd命令


3、执行composer命令

切换到中国国内镜像

复制代码 代码如下:

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

执行加载SDK命令

composer require aliyuncs/oss-sdk-php

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:

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

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

<?php
/**

 * @Last Modified by:  Marte
 * @Last Modified time: 2017-09-06 16:19:28
 */
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[&#39;oss&#39;][&#39;accessKeyId&#39;];         //获取阿里云oss的accessKeyId
    $accessKeySecret = Yii::$app->params[&#39;oss&#39;][&#39;accessKeySecret&#39;];     //获取阿里云oss的accessKeySecret
    $endpoint = Yii::$app->params[&#39;oss&#39;][&#39;endPoint&#39;];            //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[&#39;oss&#39;][&#39;bucket&#39;]; //获取阿里云oss的bucket

    $result=array();
    try{
      $getOssInfo=self::$oss->uploadFile($bucket, $object, $filepath);
      $result[&#39;url&#39;] = $getOssInfo[&#39;info&#39;][&#39;url&#39;];
      if($getOssInfo[&#39;info&#39;][&#39;url&#39;]){
        @unlink(substr($_path, 1));
      }
    }catch(OssException $e){
      var_dump($e);
      return;
    };
    $url=$result[&#39;url&#39;];
    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[&#39;oss&#39;][&#39;bucket&#39;];  //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:

  &#39;Aliyunoss&#39; => [
    &#39;class&#39; => &#39;common\components\Aliyunoss&#39;,
   ],


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

&#39;oss&#39; =>[                     //阿里云OSS
    &#39;ossServer&#39; => &#39;oss-cn-   .aliyuncs.com&#39;, //服务器外网地址,
    &#39;ossServerInternal&#39; => &#39;oss-cn-   .aliyuncs.com&#39;, //服务器内网地址
    &#39;accessKeyId&#39;=>&#39;    &#39;,
    &#39;accessKeySecret&#39;=>&#39;     &#39;,
    &#39;bucket&#39; => &#39;    &#39;,
    &#39;endPoint&#39; => &#39;     &#39;,
  ],

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[&#39;vend_banner&#39;][&#39;name&#39;]);
    $img_banner = explode(&#39;.&#39;,$img_banner);
    $imgs_banner = $img_banner[1];
    $img_banner = date(&#39;YmdHis&#39;).mt_rand(100,1000).md5($img_banner[0]);
    //文件重命名
    $vend_banners = "./images/upload/".$img_banner.&#39;.&#39;.$imgs_banner; 
    $vend_banner = $img_banner.&#39;.&#39;.$imgs_banner; 
   
    $uploadPath = dirname(dirname(__FILE__)).&#39;/web/images/upload/&#39;; // 取得临时文件路径
      if (!file_exists($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($_FILES[&#39;vend_banner&#39;][&#39;tmp_name&#39;])){ //判断是否post上传
      if(!move_uploaded_file($_FILES[&#39;vend_banner&#39;][&#39;tmp_name&#39;],$vend_banners)){
        //移动到临时目录里
        echo &#39;banner上传失败&#39;;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][&#39;vend_banner&#39;];//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
