确定此表单验证的问题

<p>我正在使用 Laravel 5.8，并且我已经制作了这个控制器方法来在数据库中创建一些记录。</p>
<pre class="brush:php;toolbar:false;">public function doTheUpload(Request $request)
{
try{
$request->validate([
'video' => 'nullable|mimes:mp4',
'video_thumb' => 'required|mimes:jpg,png,jpeg',
'video_name' => 'required',
'video_desc' => 'nullable',
'available_download' => 'nullable',
],[
'video.mimes' => 'video file format is not valid',
'video_thumb.required' => 'uploading video thumbnail is required',
'video_name.required' => 'you must enter name of video',
'video_thumb.mimes' => 'image thumbnail file format is not valid',
]);
// Do the upload process
}catch(\Exception $e){
dd($e);
}
}</pre>
<p>但这将不起作用并返回此错误：</p>
<h2><strong>给定数据无效。</strong></h2>
<p>这基本上是因为表单验证请求，当我从方法中删除这些验证时，它会工作得很好。</p>
<p>那么那些返回此错误的表单请求验证出了什么问题？</p>
<p>如果您知道，请告诉我...我非常感谢你们的任何想法或建议。</p>
<p>谢谢。</p>

您必须准确指定要验证的内容：
$request->validate([ 'request.video' => 'nullable|mimes:mp4', 'request.video_thumb' => 'required|mimes:jpg,png,jpeg', 'request.video_name' => 'required', 'request.video_desc' => 'nullable', 'request.available_download' => 'nullable', ], [ 'request.video.mimes' => 'video file format is not valid', 'request.video_thumb.required' => 'uploading video thumbnail is required', 'request.video_name.required' => 'you must enter name of video', 'request.video_thumb.mimes' => 'image thumbnail file format is not valid', ]);我的代码示例：
$requestData = $request->request_data; // data $company_name = $requestData['company_name']; $company_type = $requestData['company_type']; $company_address = $requestData['company_address']; $latitude = $requestData['latitude']; $longitude = $requestData['longitude']; $company_branch_count = $requestData['company_branch_count']; $yes_radio = strval($requestData['yes_radio']); $no_radio = strval($requestData['no_radio']); $company_contact_user_first_name = $requestData['company_contact_user_first_name']; $company_contact_user_last_name = $requestData['company_contact_user_last_name']; $company_contact_user_email = $requestData['company_contact_user_email']; $company_contact_user_password = $requestData['company_contact_user_password']; $company_contact_user_phone = $requestData['company_contact_user_phone']; $company_kvkk_ok = strval($requestData['company_kvkk_ok']); $shipping_method_yourself = $yes_radio === 'true' && $yes_radio != $no_radio ? 1 : 0; if ($company_kvkk_ok == 'false') { return json_encode([ 'operation_status' => 'error', 'error_messages' => 'no', ]); } // Validate $validator = Validator::make($request->all(), [ "request_data.company_name" => "required|string|min:5", "request_data.company_type" => "required|in:0,1,2,3,4,5,6,7,8,9,10,11,12", "request_data.company_address" => "required", "request_data.latitude" => "required", "request_data.longitude" => "required", "request_data.company_branch_count" => "required|integer", "request_data.yes_radio" => "required", "request_data.no_radio" => "required", "request_data.company_contact_user_first_name" => "required", "request_data.company_contact_user_last_name" => "required", "request_data.company_contact_user_email" => [ 'required', 'email', Rule::unique('users', 'email')->where(function ($query) use ($company_contact_user_email) { return $query->where('email', $company_contact_user_email); }), Rule::unique('companies', 'company_contact_user_email')->where(function ($query) use ($company_contact_user_email) { return $query->where('company_contact_user_email', $company_contact_user_email); }), ], "request_data.company_contact_user_password" => "required|min:6", "request_data.company_contact_user_phone" => "required", "request_data.company_kvkk_ok" => "required", ], [ 'request_data.company_name.required' => __('company name required'), 'request_data.company_name.string' => __('company name must be string'), 'request_data.company_name.min' => __('company name must be at least 5 characters'), 'request_data.company_type.required' => __('company type required'), 'request_data.company_type.in' => __('company type invalid'), 'request_data.company_address.required' => __('company address required'), 'request_data.latitude.required' => __('latitude required'), 'request_data.longitude.required' => __('longitude required'), 'request_data.company_branch_count.required' => __('company branch count required'), 'request_data.company_branch_count.integer' => __('company branch count must be integer'), 'request_data.yes_radio.required' => __('yes radio required'), 'request_data.no_radio.required' => __('no radio required'), 'request_data.company_contact_user_first_name.required' => __('company contact user first name required'), 'request_data.company_contact_user_last_name.required' => __('company contact user last name required'), 'request_data.company_contact_user_email.required' => __('company contact user email required'), 'request_data.company_contact_user_email.email' => __('company contact user email invalid'), 'request_data.company_contact_user_email.unique' => __('email already taken'), 'request_data.company_contact_user_password.required' => __('company contact user password required'), 'request_data.company_contact_user_password.min' => __('company contact user password must be at least 6 characters'), 'request_data.company_contact_user_phone.required' => __('company contact user phone required'), 'request_data.company_kvkk_ok.required' => __('company kvkk ok required'), ]); if ($validator->fails()) { $messages = $validator->messages(); return json_encode([ 'operation_status' => 'not_validated', 'request' => $requestData, 'messages' => $messages, ]); }当你使用 Laravel 的验证时，你应该让 Laravel 处理错误，因为当规则失败时，Laravel 会自动抛出异常。 因此，第一个建议是不要在验证例程中使用 try-catch 块。
正如 Laravel 文档所述： p>
此外，我建议您不要在控制器中使用验证，因为根据良好实践，建议创建单独的 formRequest 进行验证，因此您应该稍微修改控制器以包含验证器类：
<?php namespace App\Http\Controllers; ... use App\Http\Requests\UploadVideoRequest; ... public function doTheUpload(UploadVideoRequest $request) { /* * Here where are calling validation as UploadVideoRequest */ // logic for valid uploaded video }现在您必须创建一个表单请求，也许使用 php artisan make:request UploadVideoRequest 此命令将在
app/Http/Requests下创建一个表单请求类，您应将其填充为：<?php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; class UploadVideoRequest extends FormRequest { /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize() { /* * here you should check if the user is authorized to upload video * or let in true if anyone can do that */ return true; } /** * Get the validation rules that apply to the request. * * @return array */ public function rules() { return [ 'video' => 'nullable|mimes:mp4', 'video_thumb' => 'required|mimes:jpg,png,jpeg', 'video_name' => 'required', 'video_desc' => 'nullable', 'available_download' => 'nullable', ]; } /** * Define messages to return if an error is detected. * * @return array */ public function messages() { return [ 'video.mimes' => 'video file format is not valid', 'video_thumb.required' => 'uploading video thumbnail is required', 'video_name.required' => 'you must enter name of video', 'video_thumb.mimes' => 'image thumbnail file format is not valid', ]; } }通过使用这种方法，Laravel 验证用户输入并通过异常管理任何错误。
问候。
