验证请求视频文件（Laravel）

Question

问题：我以正确的格式上传视频时遇到问题。 错误说。 内容资产无法上传。

我上传的文件名是 的 history_legend.mp4

视频格式正确。

我尝试自定义我的php.ini max_upload_size到500M

但仍然无法上传错误

在控制器中：

public function content_inserting_home(Request $request)
{

    $content_bothimagevideo = $request->input('content_assets');
    $file_upload = $request->file('content_assets');

     $validatedData = $request->validate([
    'content_assets' => 'required|mimes:mp4,x-flv,x-mpegURL,MP2T,3gpp,quicktime,x-msvideo,x-ms-wmv',

    ]);


}

在Blade中

<form action="/previllage/content_inserting_home" method="post" enctype="multipart/form-data"> 
         {{csrf_field()}}
        <div class="collection">
            <a href="#!" class="collection-item active " style="border-left:5px solid black;">Home</a>
            <a href="#!" class="collection-item" style="cursor: default;">
                <div class="row">
