本教程针对 Laravel-admin 开发扩展 也适用哈！
不过本人小白！
感谢大牛 @派大星 暂时这么叫吧。如果他愿意公开 QQ 信息或者啥的，我再来更新本篇文章！
声明：本文里面实现的所有功能(dcat-admin 直连七牛云分片上传大文件)都是 @派大星 来实现的！
本人只是将其弄成了扩展形式而已，为了无损 dcat-admin。。。😂。。。
官方更新其实挺快的。。。但是一些特殊需求，官方不带屌我们的。。。
没办法，只能自己去啃啦！
可惜的是，前端的东西真心啃不动！
但是！这时候 @派大星 出现了。真心的感谢！发自内心的感谢！
@派大星 还给实现了，下拉选框多选 (multipleSelect) 的拖动排序功能，后面有空了，整理一下发给大家！
好了，感谢的话不再多言，进入今天的主题！

//# sourceMappingURL=upload.js.map
- 文件：public/js/upload.js.map （和上面的文件放一个路径）
该文件你可以直接复制
public/vendor/dcat-admin/dcat/extra/upload.js.map过来即可
加载扩展功能
- 文件：app/Admin/bootstrap.php
Form::extend('file', App\Admin\Extensions\Field\File::class);
表单里使用
// 本扩展其实就增加了qiniu这方法
$form->file('ext.a', '分块测试')->name('a.zip')
->chunked()->chunkSize(1024)->threads(5)
->maxSize(1024000)->move('b/')
->deleteUrl('api/del/qiniu_d')->qiniu('qiniu_d');
// 测试对本地上传是否有影响，测试结果是无，也可能有没测到
$form->file('ext.b', '本地分块')->name('a.zip')
->chunked()->chunkSize(1024)->threads(3)
->maxSize(1024000)->disk('public');
删除文件的方法
//->deleteUrl('api/del/qiniu_d')
public function del(Request $request,$disk)
{
$config = config("filesystems.disks.{$disk}");
$data['key'] = str_replace($config['url'],'', $request->get('key'));
$storage = Storage::disk($disk);
$storage->delete($data['key']);
$data['status'] = true;
return response()->json($data, 200);
}
//上面方法的路由
$router->put('api/del/{disk}','Api\AjaxController@del' );
