#安装七牛云插件 composer require qiniu/php-sdk
<?php /** * 七牛云 */ namespace app\extra; use Qiniu\Auth; //七牛鉴权使用 use Qiniu\Storage\UploadManager; //七牛上传使用 class UploadFile { protected $domain; protected $bucket; protected $token; protected $ACCESS_KEY ; //七牛ACCESS_KEY protected $SECRET_KEY ; //七牛SECRET_KEY public function __construct() { $this->domain = config('qiniu.DOMAIN'); $this->bucket = config('qiniu.BUCKET'); $this->ACCESS_KEY = config('qiniu.ACCESS_KEY'); $this->SECRET_KEY = config('qiniu.SECRET_KEY'); $auth = new Auth( $this->ACCESS_KEY, $this->SECRET_KEY); // 生成上传Token $this->token = $auth->uploadToken($this->bucket); } /** * 上传 * @param $file * @return array * @throws \Exception */ public function uploadOne($file) { // 构建 UploadManager 对象 $uploadMgr = new UploadManager(); list($ret, $err) = $uploadMgr->putFile($this->token, $file['name'], $file['tmp_name']); if ($err !== null) { return ['err' => 1, 'msg' => $err, 'data' => '']; } else { //返回文件的完整URL return ['err' => 0, 'msg' => '上传完成', 'data' => ($this->domain . $ret['key'])]; } } }
