我正在使用 laravel 内置文件上传将视频上传到我的网站。我已经成功上传了文件，但是当我的朋友尝试上传视频时，他收到错误“validation.uploaded”，我不知道为什么会发生这种情况，我一直在尝试查找错误，但我找不到没找到。我们都在 firefox 和 chrome 中尝试过，但只有我的朋友得到了它。请帮助这是我的代码：
Save Video Function

$fileName = str_random(40);
$fullFileName = $fileName.'.'.$video->guessClientExtension();
$video->storeAs('videos', $fileName);
return $fullFileName;
}

从表单保存
public function update(Request $request, $id)

//dd($request->all());
$video = Video::findOrFail($id);
$this->validate($request, [
'title' => 'required|unique:lessons,title,'.$video->id,
'lesson_lists' => 'required',
'description' => 'required'
]);
$data = $request->only('title', 'description','lesson_lists');
$data['slug'] = str_slug($request->title);
if($request->hasFile('image')){
$data['image'] = $this->saveImage($request->file('image'));
if($video->image !== '') $this->deletePhoto($video->image);
}
if($request->hasFile('video')){
$data['video'] = $this->saveVideo($request->file('video'));
if($video->video !== '') $this->deleteVideo($video->video);
}
//$data['lesson_id'] = implode($request->get('lesson_lists'));
$video->update($data);
Session::flash("flash_notification", [

return redirect()->route('video.index');
}

Actually if the size of file you try to download exceeds the "upload_max_filesize" the Laravel shows this validation error, so you must open the php.ini file and set the options like this:
实际上，如果您尝试下载的文件大小超过“upload_max_filesize”，Laravel 会显示此验证错误，因此您必须打开 php.ini 文件并设置如下选项：
post_max_size = 500M
post_max_size = 500M
upload_max_filesize = 500M
upload_max_filesize = 500M
Notice: if you use wamp or xamp don't forget to restart it otherwise rerun the command:
注意：如果您使用 wamp 或 xamp，请不要忘记重新启动它，否则请重新运行命令：
php artisan serve

Laravel responses 422 Unprocessable Entitywhich response body contains validation.uploadeddue to exceed upload size limitation. Try to set proper value for following possible parameters(e.g. 10M):
Laravel 响应422validation.uploaded由于超出上传大小限制，响应正文包含的不可处理实体。尝试为以下可能的参数设置适当的值（例如 10M）：
/etc/php.ini(PHP):
/etc/php.ini(PHP):
- upload_max_filesize 10M
- post_max_size 10M
- upload_max_filesize 10M
- post_max_size 10M
.htaccess(Apache):
.htaccess（阿帕奇）：
- php_value upload_max_filesize 10M
- php_value post_max_size 10M
- php_value upload_max_filesize 10M
- php_value post_max_size 10M
Then restart Apache sudo systemctl restart httpd.service(Cent OS 7)
然后重启Apache sudo systemctl restart httpd.service（Cent OS 7）
