<form class="form-horizontal" id="avatar"> 
   {{ csrf_field() }}
 <div class="form-group">
 <label for="inputEmail3" class="col-sm-2 control-label">名字</label>
 <div class="col-sm-8">
  <input type="title" class="form-control" id="title" name="title">
 </div>
 </div>


 <div class="form-group">
 <label for="inputEmail3" class="col-sm-2 control-label">头像</label>
 <div class="col-sm-8">
  <input type="file" class="form-control" id="title" name="photo">
 </div>
 </div>


 <div class="form-group">
 <div class="col-sm-offset-2 col-sm-10">
  <a class="btn btn-default" onclick="uploadInfo()">上传</a>
 </div>
 </div>
</form>

<script src="/UploadFiles/2021-04-02/jquery.min.js">



 //生成路径，图片存储
  $ext = $request->photo->getClientOriginalExtension();
  $cover_path = "images/album/covers/" . time() . $ext; 
  $name = "photo".time();
  $src = "images/album/photos/". $name .".jpg";
  Image::make($request->photo)->save(public_path($src));*/

 //批量上传图片

  foreach ($request->photo as $key => $value) {
   //生成路径，图片存储
   $prefix = "photo".mt_rand(1,1000);
   $Origname = $value->getClientOriginalName();
   $name = $prefix.$Origname;
   $src = "images/album/photos/".$name;
   $realPath = $value->getRealPath();
   Storage::disk('uploads')->put($src,file_get_contents($realPath));
  }
