oss文件上传与签名
相信大家日常开发中，经常使用到云文件的上传与下载等功能，而国内常用的阿里云和华为云，laravel 自带的 Storage 默认并未进行友好支持。
刚好最近云迁移过程中的各种恶心，主要涉及上传与签名接口。特地记录下 OSS 云环境文件上传与签名的重点代码，以供参考。
相关包安装命令：
// 阿里云oss composer require aliyuncs/oss-sdk-php // 华为云obs composer 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OBS OSS_HW_ENDPOINT=https://obs.cn-east-3.myhuaweicloud.com OSS_HW_KEY=ME0AVBTNJTSJB2LH0EGI OSS_HW_SECRET=eCGffrwdx3Rt5QEmKbtEvruvGgg1mCUjMsnHfjWo OSS_HW_BUCKET=pub-obs-test-1 #阿里云 OSS_ENDPOINT=https://oss-cn-hangzhou.aliyuncs.com OSS_KEYID=LTAI4Ftno9DsfiVHADX73osa OSS_KEYSECRET=vo9KuqgaDN727eOOz1tDg77Egeg7wE OSS_BUCKET=xgimi-ipr

1. 接口声明
2. 阿里 OSS 实现
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) { } } /** * 上传 * * @param $fullFileName * @param $filePath * @return mixed * @throws \Exception */ public function publicUpload($fullFileName, $filePath) { return $this->ossClient->uploadFile($this->bucket, $fullFileName, $filePath); } /** * url验签、下载 * * @param $fullFileName * @param $expires | 过期时效 * @return mixed * @throws \Exception */ public function getUrl($fullFileName, $expires) { $expires = $expires ? $expires : $this->expires; $signUrl = $this->ossClient->signUrl($this->bucket, $fullFileName, $expires); return $signUrl; } /** * 替换url域名 * * @param $url * @return mixed */ public function replaceUrl($url) { return str_replace($this->aliHost, $this->myHost, $url); } }3. 华为 OBS 实现
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) { } } /** * 上传 * * @param $fullFileName * @param $filePath * @return mixed */ public function publicUpload($fullFileName, $filePath) { $res = $this->obsClient->putObject([ 'Bucket' => $this->bucket, 'Key' => $fullFileName, 'SourceFile' => $filePath ]); return $res; } /** * url验签、下载 * * @param $fullFileName * @param $expires | 过期时效 * @return mixed * @throws \Exception */ public function getUrl($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']; } /** * 替换url域名 * * @param $url * @return mixed */ public function replaceUrl($url) { return str_replace($this->hwHost, $this->myHost, $url); } }Demo: 业务逻辑 + OSS 类
false, 'message' => '请上传文件！']; } if (is_array($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！']; } } } }OSSService = new HuaweiOBS(); } else { $this->OSSService = new AliOSS(); } } public static function getInstance() { return new self(); } /** * 使用外网上传文件 * * @param $fullName * @param $filePath * @param $prefix * @return mixed * @throws Exception */ public static function publicUpload($fullName, $filePath, $prefix) { return self::getInstance()->OSSService->publicUpload($fullName, $filePath); } /** * 获取oss图片url * * @param $fullName * @param $expires | 过期时效 * @return string * @throws Exception */ public static function getUrl($fullName, $expires = '') { return self::getInstance()->OSSService->getUrl($fullName, $expires); } /** * 替换url域名 * * @param $url * @return mixed */ public static function replaceUrl($url) { return self::getInstance()->OSSService->replaceUrl($url); } /** * 获取完整的文件名含路径 * * @param $fileName * @param $prefix * @return string */ public static function getFullFileName($fileName, $prefix) { return self::OSS_PREFIX . $prefix . self::setFileName($fileName); } /** * 设置新的文件名(重命名规则) * * @param $fileName * @return string */ public static function setFileName($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。
