Thinkphp6使用七牛云

问题描述：在开发项目的时候，需要用到七牛云用以保存附件

步骤：

1. 下载七牛云所需要的文件

composer require qiniu/php-sdk

2. 在七牛云上注册自己的账号，获取两个密匙AK、SK和空间名称
   
   

3. 新建一个配置文件qiniu.php
   

4. 控制器代码

declare (strict_types = 1);namespace app\controller;use app\BaseController;use app\Request;use think\App;use Qiniu\Storage\UploadManager;use app\service\Qiniu as QiniuService;use think\facade\Db;use think\facade\View;class QiniuUpload extends BaseController{    protected $service;    public function __construct(App $app, QiniuService $service)    {        parent::__construct($app);        $this->service = $service;    }    public function index()    {        View::assign(            [                'token'=>$this->service->getUpToken()            ]        );        return view();    }        public function uploadFile(Request $request)    {        $fileName = $request->post('file_name');        $token = $request->post('upload_token');        $image = $request->file('file');//        获取临时路径        $filePath = $image->getRealPath();//        获取文件后缀        $ext = $image->getOriginalExtension();//        上传到七牛后保存的新文件名        $newImageName = $fileName.rand(00000,99999).'.'.$ext;//        初始化UploadManager        $uploadMgr = new UploadManager();        // 调用 UploadManager 的 putFile 方法进行文件的上传。        list($ret, $err) = $uploadMgr->putFile($token,$newImageName,$filePath);        if ($err !== null){            dump($err);            return null;        }else{//            图片上传成功            $dataTpl = [              'fname' => $fileName,                'key' => $ret['key']            ];            Db::name('qiniu')->save($dataTpl);            return '上传成功';        }    }    public function downloadFile()    {        $dataList = Db::name('qiniu')->select()->toArray();        $finalArr = array();        foreach ($dataList as $data)        {            $tpl['name'] = $data['fname'];            $tpl['key'] = $data['key'];            $tpl['url'] = $this->service->getSignedUrl($data['key']);            $finalArr[] = $tpl;        }        View::assign(            ['dataList'=>$finalArr]        );        return view();    }    public function del(Request $request)    {        $key = $request->get('key');        $res = Db::name('qiniu')->where('key',$key)->delete();        if($res)        {            if($this->service->delete($key))            {                return '都删除成功了！';            }else{                return '数据库删除成功了，但是七牛上没删除成功！';            }        }else{            return '删除失败！';        }    }    public function allFile()    {        $this->service->getFileList();    }}

5. Service代码

namespace app\service;use think\facade\Config;use Qiniu\Auth;use Qiniu\Config as QiniuConfig;use Qiniu\Storage\BucketManager;use const true;class Qiniu{    public function getUpToken()    {        $accessKey = Config::get('qiniu.access_key');        $secretKey = Config::get('qiniu.secret_key');        $bucket = Config::get('qiniu.bucket_name');        $auth = new Auth($accessKey, $secretKey);        return $auth->uploadToken($bucket);    }    public function getSignedUrl($key)    {        $accessKey = Config::get('qiniu.access_key');        $secretKey = Config::get('qiniu.secret_key');        $auth = new Auth($accessKey, $secretKey);        $bucket_domain = Config::get('qiniu.bucket_domain');        $baseUrl = $bucket_domain.$key;        return $auth->privateDownloadUrl($baseUrl);    }    public function delete($key)    {        $accessKey = Config::get('qiniu.access_key');        $secretKey = Config::get('qiniu.secret_key');        $bucket = Config::get('qiniu.bucket_name');        $auth = new Auth($accessKey, $secretKey);        $conf = new QiniuConfig();        $bucketManager = new BucketManager($auth,$conf);        $err = $bucketManager->delete($bucket,$key);        if ($err) {            print_r($err);            return 1;        }else{            return 1;        }    }    public function getFileList()    {        $accessKey = Config::get('qiniu.access_key');        $secretKey = Config::get('qiniu.secret_key');        $bucket = Config::get('qiniu.bucket_name');        $auth = new Auth($accessKey, $secretKey);        $bucketManager = new BucketManager($auth);// 要列取文件的公共前缀        $prefix = '';// 上次列举返回的位置标记，作为本次列举的起点信息。        $marker = '';// 本次列举的条目数        $limit = 100;        $delimiter = '/';// 列举文件        list($ret, $err) = $bucketManager->listFiles($bucket, $prefix, $marker, $limit, $delimiter);        if ($err !== null) {            echo "\n====> list file err: \n";            var_dump($err);        } else {            foreach ($ret['items'] as $item)            {                echo "
".$item['key'];            }//            dump($ret['items']);//            if (array_key_exists('marker', $ret)) {//                echo "Marker:" . $ret["marker"] . "\n";//            }//            echo "\nList Iterms====>\n";            dump($ret['items']);        }    }}
