laravel使用layui 上传文件 支持pdf上传

控制器：

file('file');//获取图片
        $allowed_extensions = ["png", "jpg", "gif","pdf"]; //多类型
        //图片是否是正规图片
        if ($file->getClientOriginalExtension()&&!in_array
            ($file->getClientOriginalExtension(),$allowed_extensions)) {
            $data=[
                'status'=>-1,
                'msg'=>'不支持此格式'
            ];
            return json_encode($data);
        }
        if($request->hasFile('photo')) {

        }
        //保存图片
        $path=date('Y/m/d/',time());
        $destinationPath ='uploads/blog/'.$path;
        is_dir($destinationPath) or mkdir($destinationPath,0777,true);

        $extension = $file->getClientOriginalExtension();
        $fileName = md5(str_random(10) . time()) . '.' . $extension;
        $file->move($destinationPath, $fileName);
        $data=[
            'status'=>1,
            'msg'=>$destinationPath.$fileName
        ];
        return json_encode($data);
    }
}

                ,accept: 'file'

                        $('#img_file').find('img').attr('src',"{

                        $("#fileimg").val(res.msg)
                        return layer.msg('图片上传成功！');
