OSS文件上传与签名
相关包安装命令：
// 阿里云osscomposer require aliyuncs/oss-sdk-php// 华为云obscomposer require obs/esdk-obs-php
需注意包版本，是否与 php 版本适用。
.env 配置项：
# OSS相关配置OSS_DRIVER=HW_OBS#华为OBSOSS_HW_ENDPOINT=https://obs.cn-east-3.myhuaweicloud.comOSS_HW_KEY=ME0AVBTNJTSJB2LH0EGIOSS_HW_SECRET=eCGffrwdx3Rt5QEmKbtEvruvGgg1mCUjMsnHfjWoOSS_HW_BUCKET=pub-obs-test-1#阿里云OSS_ENDPOINT=https://oss-cn-hangzhou.aliyuncs.comOSS_KEYID=LTAI4Ftno9DsfiVHADX73osaOSS_KEYSECRET=vo9KuqgaDN727eOOz1tDg77Egeg7wEOSS_BUCKET=xgimi-ipr
代码：
接口声明
<?phpnamespace App\Service\OSS;interface IOSS{ public function publicUpload($fullFileName, $filePath); public function getUrl($fullFileName, $expires); public function replaceUrl($url);}
阿里 OSS 实现
<?phpnamespace App\Service\OSS;use OSS\OssClient;class AliOSS implements IOSS{ private $endPoint; private $keyId; private $secret; private $bucket; private $ossClient; private $expires = 3 * 24 * 3600; private $aliHost = ''; private $myHost = ''; public function __construct() { $this->endPoint = env("OSS_ENDPOINT"); $this->keyId = env("OSS_KEYID"); $this->secret = env("OSS_KEYSECRET"); $this->bucket = env("OSS_BUCKET"); try { $this->ossClient = new OssClient($this->keyId, $this->secret, $this->endPoint); } catch (\Exception $e) { } } public function publicUpload($fullFileName, $filePath) { return $this->ossClient->uploadFile($this->bucket, $fullFileName, $filePath); } public function getUrl($fullFileName, $expires) { $expires = $expires ? $expires : $this->expires; $signUrl = $this->ossClient->signUrl($this->bucket, $fullFileName, $expires); return $signUrl; } public function replaceUrl($url) { return str_replace($this->aliHost, $this->myHost, $url); }}
华为 OBS 实现
<?phpnamespace App\Service\OSS;use Obs\ObsClient;class HuaweiOBS implements IOSS{ private $endPoint; private $key; private $secret; private $bucket; private $obsClient; private $expires = 3 * 24 * 3600; private $hwHost = ''; private $myHost = ''; public function __construct() { $this->endPoint = env("OSS_HW_ENDPOINT"); $this->key = env("OSS_HW_KEY"); $this->secret = env("OSS_HW_SECRET"); $this->bucket = env("OSS_HW_BUCKET"); try { $this->obsClient = new ObsClient(['key' => $this->key, 'secret' => $this->secret, 'endpoint' => $this->endPoint]); } catch (\Exception $e) { } } public function publicUpload($fullFileName, $filePath) { $res = $this->obsClient->putObject([ 'Bucket' => $this->bucket, 'Key' => $fullFileName, 'SourceFile' => $filePath ]); return $res; } public function getUrl($fullFileName, $expires) { $expires = $expires ? $expires : $this->expires; // 生成下载对象的带授权信息的URL $res = $this->obsClient->createSignedUrl([ 'Method' => 'GET', 'Bucket' => $this->bucket, 'Key' => $fullFileName, 'Expires' => $expires ]); return $res['SignedUrl']; } public function replaceUrl($url) { return str_replace($this->hwHost, $this->myHost, $url); }}
Demo: 业务逻辑 + OSS 类
<?phpnamespace App\Service;class UploadFile{ public static function upload($files, $prefix = '') { if (empty($files)) { return ['ok' => false, 'message' => '请上传文件！']; } if (is_array($files)) { $pics = []; foreach ($files as $key => $file) { if ($file->isValid()) { $name = $file->getClientOriginalName(); $fullName = OSS::getFullFileName($name, $prefix); $ret = OSS::publicUpload($fullName, $file, $prefix); if ($ret) { $url = OSS::getUrl($fullName); $url = OSS::replaceUrl($url); $pics[] = ['name' => $name, 'url' => $url, 'file_name' => $fullName]; } } else { return ['ok' => false, 'message' => '无效文件！']; } } if (count($pics) > 0) { return ['ok' => true, 'data' => $pics]; } } else { $name = $files->getClientOriginalName(); $fullName = OSS::getFullFileName($name, $prefix); $ret = OSS::publicUpload($fullName, $files, $prefix); if ($ret) { $url = OSS::getUrl($fullName); $url = OSS::replaceUrl($url); return ['ok' => true, 'data' => ['name' => $name, 'url' => $url, 'file_name' => $fullName]]; } else { return ['ok' => false, 'message' => '无效文件！']; } } }}<?phpnamespace App\Service;use App\Service\OSS\AliOSS;use App\Service\OSS\HuaweiOBS;use Exception;class OSS{ const DEFAULT_DRIVER = 'HW_OBS'; const OSS_PREFIX = 'oss/'; public $OSSService; public function __construct() { if (env('OSS_DRIVER') === self::DEFAULT_DRIVER) { $this->OSSService = new HuaweiOBS(); } else { $this->OSSService = new AliOSS(); } } public static function getInstance() { return new self(); } public static function publicUpload($fullName, $filePath, $prefix) { return self::getInstance()->OSSService->publicUpload($fullName, $filePath); } public static function getUrl($fullName, $expires = '') { return self::getInstance()->OSSService->getUrl($fullName, $expires); } public static function replaceUrl($url) { return self::getInstance()->OSSService->replaceUrl($url); } public static function getFullFileName($fileName, $prefix) { return self::OSS_PREFIX . $prefix . self::setFileName($fileName); } public static function setFileName($fileName) { $nameArray = explode('.', $fileName); $extension = $nameArray[count($nameArray) - 1]; $newName = date('Ymd') . '/' . date('YmdHis') . rand(10000, 99999) . '.' . $extension; return $newName; }}
有时间可以对其进行功能接口补充，丰富更多云接口能力。
附：
composer 包：https://packagist.org/packages/league/flysystem
composer require league/flysystem
