基于PHP后台上传图片到阿里云

布满荆棘的人生 2023-02-14 05:55 24阅读 0赞

第一步：先下载PHP SDK包放到根目录的Vendor下。SDK下载地址：https://github.com/aliyun/aliyun-oss-php-sdk?spm=a2c63.p38356.a3.2.3b8d7557Adllch  
![在这里插入图片描述][20200601112559218.png]  
第二步：登录阿里云，创建bucket，地址：https://oss.console.aliyun.com/bucket  
Bucket 是存储桶的意思，用来存储文件用的。名字可以自定，跟腾讯云的命名有所不同。

注意：读写权限要设置成公有读私有写，上图红框所示。否则会出错的。

## 方法一：uploadFile ##

/** * 阿里云图片上传 * @param $local_path 本地文件或临时文件路径 * @param $aliyunImg 阿里云路径 * @param $ext 图片后缀 * @return |null */
        public function uploadAliyun($local_path,$aliyunImg,$ext)
        { 
            include_once $_SERVER['DOCUMENT_ROOT']."/vendor/aliyun-oss-php-sdk-master/autoload.php";
    
            $accessKeyId = 'LTAI4G27kVGxTdtw1ovvATE5';
            $accessKeySecret = '9HPp1wHOBQGzjnAqRfTz2VfiQxAv2t';
            $endpoint = 'oss-cn-shenzhen.aliyuncs.com';
            $bucket = 'hanlusir-shop';
    
            try { 
                $ossClient = new \OSS\OssClient($accessKeyId, $accessKeySecret, $endpoint);
                $result = $ossClient->uploadFile($bucket, $aliyunImg, $local_path,['Content-Type'=>'image/'.$ext]);
                return $result['info']['url'];
            } catch (\Exception $e) { 
                echo $e->getMessage();
                return null;
            }
    
        }

第二个参数阿里云路径可以写成带目录结构的，如果目录不存在的话，阿里云会自动创建目录。

## 方法二：putObject ##

/**
     * 阿里云图片上传
     * @param $local_path   本地文件或临时文件路径
     * @param $aliyunImg    阿里云路径   可以带上目录
     * @param $ext          图片后缀\与上传图片保持一致
     * @return |null
     */
    function uploadAliyun( $local_path , $aliyunImg , $ext = 'jpg' )
    { 
        include_once $_SERVER['DOCUMENT_ROOT']."/../vendor/aliyun-oss-php-sdk-master/autoload.php";
        $aliyunInfo = db('aliyun_config')->find(1);
        $accessKeyId = $aliyunInfo['accessKey_id'];
        $accessKeySecret = $aliyunInfo['accessKey_secret'];
        $endpoint = 'oss-cn-shenzhen.aliyuncs.com';
        $bucket = 'img-ddeessign';
        $local_path = file_get_contents($local_path);
        try { 
            $ossClient = new \OSS\OssClient($accessKeyId, $accessKeySecret, $endpoint);
            $options = array(
                \OSS\OssClient::OSS_HEADERS => array(
                    'Cache-Control' => 'no-cache',
                    'Content-Type'=>'image/'. $ext
                ));
            $result = $ossClient->putObject($bucket, $aliyunImg, $local_path, $options);
            $root_path = 'img.7654321.ddeessign';
            $url = 'img-ddeessign.oss-cn-shenzhen.aliyuncs.com';
            return str_replace($url, $root_path, $result['info']['url']);
        } catch (\Exception $e) { 
            echo $e->getMessage();
            return null;
        }
    
    }

使用示例：

$local_path = $param['files']['tmp_name'];
    $ext = pathinfo($param['files']['name'],PATHINFO_EXTENSION);
    $aliyunImg = $param['savePath'].$param['saveName'] . '.' . $ext;
    $r = $this->uploadAliyun($local_path,$aliyunImg,$ext);

## 方法一和二侧重点不同，随需选择。 ##

注意：如果你上传的文件是下载而不是直接预览的话，那么设置就是有问题的。  
可以参考本人另外一篇文章：
