YII2调用阿里云Oss 对象存储服务

一.YII2使用阿里云Oss

---

composer安装Oss-Skd包 地址 :: https://www.yiichina.com/code/1078

实例代码

    //根据使用composr安装的skd 编写的上传 ，此处在sdk包中的OssClient类做出了更改
    /**
    * $path 形式为 '/image/2019-02-26/aa.png' 无需携带域名
    */
    public function ossUpload($path,$file){
        $config = \Yii::$app->params['alioss'];
        $obj = new OssClient($config['accesskey'], $config['secret'], $config['endpoint']);
        $res = $obj->uploadFile($config['bucket'], $path, $file);  //此处返回的是对象，乱七八糟一大堆 只有一个status 和header['oss-request-url']有用 
        // if(isset($res->header))
        if(isset($res->status) and $res->status == 200)
        {
           return $res->header['oss-request-url']; //此处url可直接访问 只不过是原图未压缩
        }
        return false;
    }

OssClient的修改

    //构造方法的更改 这些更改只是将参数挪动到了 构造方法里边
    public function __construct($accessKeyId, $accessKeySecret, $endpoint, $isCName = false, $securityToken = NULL, $requestProxy = NULL)
    {
        $accessKeyId = trim($accessKeyId);
        $accessKeySecret = trim($accessKeySecret);
        $endpoint = trim(trim($endpoint), "/");

        if (empty($accessKeyId)) {
            throw new OssException("access key id is empty");
        }
        if (empty($accessKeySecret)) {
            throw new OssException("access key secret is empty");
        }
        if (empty($endpoint)) {
            throw new OssException("endpoint is empty");
        }
        $this->hostname = $this->checkEndpoint($endpoint, $isCName);
        $this->accessKeyId = $accessKeyId;
        $this->accessKeySecret = $accessKeySecret;
        $this->securityToken = $securityToken;
        $this->requestProxy = $requestProxy;

        self::checkEnv();
    }
 
    //执行上传的方法的更改 
   public function uploadFile($bucket, $object, $file, $options = NULL)
    {
        $this->precheckCommon($bucket, $object, $options);
        OssUtil::throwOssExceptionWithMessageIfEmpty($file, "file path is invalid");
        $file = OssUtil::encodePath($file);
        if (!file_exists($file)) {
            throw new OssException($file . " file does not exist");
        }
        $options[self::OSS_FILE_UPLOAD] = $file;
        $file_size = filesize($options[self::OSS_FILE_UPLOAD]);
        $is_check_md5 = $this->isCheckMD5($options);
        if ($is_check_md5) {
            $content_md5 = base64_encode(md5_file($options[self::OSS_FILE_UPLOAD], true));
            $options[self::OSS_CONTENT_MD5] = $content_md5;
        }
        if (!isset($options[self::OSS_CONTENT_TYPE])) {
            $options[self::OSS_CONTENT_TYPE] = $this->getMimeType($object, $file);
        }
        $options[self::OSS_METHOD] = self::OSS_HTTP_PUT;
        $options[self::OSS_BUCKET] = $bucket;
        $options[self::OSS_OBJECT] = $object;
        $options[self::OSS_CONTENT_LENGTH] = $file_size;
        $response = $this->auth($options);
        return $response;

    }

二.图片压缩处理 只需要携带对应的后缀即可

原图清晰度的60% 
http://demo.oss-cn-xxxxx.aliyuncs.com/test.jpg?x-oss-process=image/quality,q_80 
原图清晰度的80%

裁剪
