用法 Usage

1. 上传一个文件 Upload and store a file.

   
       use zgldh\UploadManager\UploadManager;
   
       class UploadController extend Controller
       {
           public function postUpload(Request $request)
           {
               $file = $request->file('avatar');
               $manager = UploadManager::getInstance();
               $upload = $manager->upload($file);
               $upload->save();
               return $upload;
           }
       }
   

2. 从一个URL获取并保存文件 Fetch and store a file from a URL

   
       use zgldh\UploadManager\UploadManager;
   
       class UploadController extend Controller
       {
           public function postUpload(Request $request)
           {
               $fileUrl = $request->input('url');
               $manager = UploadManager::getInstance();
               $upload = $manager->upload($fileUrl);
               $upload->save();
               return $upload;
           }
       }
   

3. 更新一个上传对象 Update a upload object

   
       use App\Upload;
       use zgldh\UploadManager\UploadManager;
   
       class UploadController extend Controller
       {
           public function postUpload(Request $request)
           {
               $uploadId = $request->input('id');
               $file = $request->file('avatar');
   
               $manager = UploadManager::getInstance();
               $upload = Upload::find($uploadId);
               if($manager->update($upload, $file))
               {
                   $upload->save();
                   return $upload;
               }
               return ['result'=>false];
           }
       }
   

4. 用从一个URL获取到的文件来更新一个上传对象 Update a upload object from a URL

   
       use App\Upload;
       use zgldh\UploadManager\UploadManager;
   
       class UploadController extend Controller
       {
           public function postUpload(Request $request)
           {
               $uploadId = $request->input('id');
               $fileUrl = $request->input('url');
   
               $manager = UploadManager::getInstance();
               $upload = Upload::find($uploadId);
               if($manager->update($upload, $fileUrl))
               {
                   $upload->save();
                   return $upload;
               }
               return ['result'=>false];
           }
       }
   

5. 数据验证 Validation

   
       use zgldh\UploadManager\UploadManager;
   
       class UploadController extend Controller
       {
           public function postUpload(Request $request)
           {
               $file = $request->file('avatar');
               $manager = UploadManager::getInstance();
               $upload = $manager->withValidator('image')->upload($file);    //加上验证组
   
               if($upload)
               {
                   $upload->save();
                   return $upload;
               }
               else
               {
                   $errorMessages = $manager->getErrors();                   //得到所有错误信息
                   $errorMessage = $manager->getFirstErrorMessage();         //得到第一条错误信息
                   throw new \Exception($errorMessage);
               }
           }
       }
   

6. 存到别的Disk里面

   
       use zgldh\UploadManager\UploadManager;
   
       class UploadController extend Controller
       {
           public function postUpload(Request $request)
           {
               $file = $request->file('avatar');
               $manager = UploadManager::getInstance();
               $upload = $manager
                   ->withValidator('image')
                   ->withDisk('qiniu')         // 储存到七牛磁盘里
                   ->upload($file);
               $upload->save();
               return $upload;
           }
       }
   

7. 上传前修改$upload 对象

   
       use zgldh\UploadManager\UploadManager;
   
       class UploadController extend Controller
       {
           public function postUpload(Request $request)
           {
               $file = $request->file('avatar');
               $manager = UploadManager::getInstance();
               $upload = $manager
                   ->withValidator('image')
                   ->withDisk('localhost')         // 默认存到本地
                   ->upload($file, function($upload){
                       if($upload->size > 1024*1024)
                       {
                           $upload->disk = 'qiniu';// 超过1兆的文件都放到七牛里。
                       }
                       return $upload;
                   });
               $upload->save();
               return $upload;
           }
       }
   

8. 删除某用户上传后，却一直没有使用的avatar类型的$upload 对象

   
       use zgldh\UploadManager\UploadManager;
   
       class UploadController extend Controller
       {
           public function clearUnUsed(Request $request)
           {
               $currentUser = $request->user();
               $manager = UploadManager::getInstance();
               $manager->removeUnUsedUploads($currentUser, 'avatar');
           }
       }
   

配置 Configuration

1. config/upload.php

   请查看源文件注释

2. App\Upload

   可以在里面写自己喜欢的函数

3. UploadStrategy.php

   通常需要你亲自扩展一个出来。如：

   
       <?php namespace App\Extensions;
   
       use zgldh\UploadManager\UploadStrategy as BaseUploadStrategy;
       use zgldh\UploadManager\UploadStrategyInterface;
   
       class UploadStrategy extends BaseUploadStrategy implements UploadStrategyInterface
       {
   
           /**
            * 生成储存的相对路径
            * @param $filename
            * @return string
            */
           public function makeStorePath($filename)
           {
               $path = 'i/' . $filename;
               return $path;
           }
   
           /**
            * 得到 disk localuploads 内上传的文件的URL
            * @param $path
            * @return string
            */
           public function getLocaluploadsUrl($path)
           {
               $url = url('uploads/' . $path);
               return $url;
           }
   
           /**
            * 得到 disk qiniu 内上传的文件的URL
            * @param $path
            * @return string
            */
           public function getQiniuUrl($path)
           {
               $url = 'http://' . trim(\Config::get('filesystems.disks.qiniu.domain'), '/') . '/' . trim($path, '/');
               return $url;
           }
       } 
   

   然后在 config/upload.php 里面配置 upload_strategy 为你自己扩展的类即可。
