Yii2.0 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 /** * @Author: Marte * @Date: 2017-09-04 11:31:20 * @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['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', ],
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' => ' ', ],
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

The above is the detailed content of Yii2.0 uses Alibaba Cloud OSS SDK to upload, download, and delete images.. For more information, please follow other related articles on the PHP Chinese website!

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
