The back-end php uses the laravel framework, which is very convenient :

public function uploadFile(Request $request){
    set_time_limit(100);    // dd(request()->all());
    $type = request('type', 0);    
    if ($type == 1) {
            $rules = [            'document' => 'sometimes|required|file|mimes:word,ppt,pdf,jpg,png,jpeg|max:10240',
        ];
    } else {        
            $rules = [            'file' => 'required|image|max:2048',
        ];
    }    
    $validator = Validator::make($request->all(), $rules);    
    if ($validator->fails())
     {        
      $error_message = $validator->errors()->all();        
      return $type == 1 ? false : $this->outPutJson('', 501, $error_message);
    }
        $file = $type == 1 ? $request->file('document') : $request->file('file');    
        $save_path = 'courseware';    
        $mime_type = $file->getClientOriginalExtension();    //保存文件
    $save_name = date('Ymd_H_i_s_') . uniqid() . '.' . $mime_type;    
    $path = $file->storeAs($save_path, $save_name, 'ftp');    
    return $type == 1 ? $path : $this->outPutJson($path);
