Laravel 上传文件到阿里云

Posted 2020-12-22

1. 在laravel 安装的根目录下，执行命令 composer require aliyuncs/oss-sdk-php 下载阿里云sdk。
   

2. 代码实现，上传文件类

   
   use OSSCoreOssException;
   use OSSOssClient;

//上传图片
class uploadImgCombine
{
/**

• 上传本地图片到oss
• @param string $sourcePath 本地源文件地址
• @param string $format 保存的文件后缀
• @param string $imgFullName 自定义保存的文件名+后缀
• @param string $folder 自定义保存的目录 如 product
• @param boolean $save 是否保存到数据库

• @return array|string
  */
  public function uploadLocalToOss($sourcePath, $format = ‘jpg‘, $imgFullName = ‘‘, $folder = ‘‘, $save = false)
  {
  //检查图片是否是OSS地址
  if (!file_exists($sourcePath))
  {
  return [‘msg‘ => ‘文件不存在‘, ‘code‘ => 1001];
  }

  // 文件名称(传到OOS后要保证唯一，重名的无法上传)
  $object = $imgFullName ? $imgFullName : date(‘YmdHis‘).CommonHelpers::rand(4, 0).‘.‘.$format;
  
  //oss保存地址
  $ossSaveFilePath = $folder ? $folder.‘/‘.$object : $object;
  
  //读取配置
  //$conf = json_decode(getenv(‘ALIYUN‘), true);
  //$accessKeyId = $conf[‘appkey‘] ?? ‘‘;
  //$accessKeySecret = $conf[‘secret‘] ?? ‘‘;
  //$endpoint = $conf[‘endpoint‘] ?? ‘‘;
  
  $accessKeyId = env(‘ALIYUN_ACCESS_KEY_ID‘);
  $accessKeySecret = env(‘ALIYUN_ACCESS_KEY_SECRET‘);
  $endpoint = env(‘ALIYUN_OSS_ENDPOINT‘);
  
  // 存储空间名称
  $bucket = env(‘ALIYUN_OSS_BUCKET‘) ?? ‘‘;
  
  try
  {
      //上传
      $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);
      $rel = $ossClient->uploadFile($bucket, $ossSaveFilePath, $sourcePath);
  }
  catch (OssException $e)
  {
      return [‘msg‘ => $e->getMessage(), ‘code‘ => $e->getCode()];
  }
  
  //验证是否上传成功
  if (isset($rel[‘oss-request-url‘]))
  {
      $id = ‘‘;
  
      //保存到数据库
      /*if($save)
      {
          $id = CommonImageModel::saveOneData([
              ‘root_url‘ => $ossSaveFilePath,
              ‘small_url‘ => $ossSaveFilePath,
              ‘create_time‘ => time(),
              ‘origin_url‘ => ‘‘,
          ]);
      }*/
  
      return [
          ‘filePath‘ => env(‘ALIYUN_OSS_URL‘) . $ossSaveFilePath,
          ‘id‘ => $id
      ];
  }
  
  //返回
  return [‘msg‘ => ‘上传失败‘, ‘code‘ => 1201];

  }

}

使用这个类

if(empty($attachment)){
return JsonResult::fail([],‘请上传文件‘);
}

            if($attachment->getSize() > 300*1024*1024)
            {
                return JsonResult::fail([],‘上传作品不能超过300M‘);
            }

            if(!$attachment || !$attachment->isValid())
            {
                return JsonResult::fail([],‘上传作品失败‘);
            }

            //上传
            $filePath = $attachment->getRealPath(); //获取文件临时存放位置
            $format = $attachment->getClientOriginalExtension();//上传文件的后缀
            $result = (new uploadImgCombine())->uploadLocalToOss($filePath, $format, ‘‘, ‘work‘, true);

            //返回
            if(isset($result[‘msg‘]))
            {
                return JsonResult::fail([], $result[‘msg‘], $result[‘code‘]);
            }
            $attachment_path = $result[‘filePath‘];
