<p>我正在使用 Laravel 5.8,並且我已經製作了這個控制器方法來在資料庫中建立一些記錄。 </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>但這將不起作用並返回此錯誤:</p> <h2><strong>給定資料無效。 </strong></h2> <p>這基本上是因為表單驗證請求,當我從方法中刪除這些驗證時,它會運作得很好。 </p> <p>那麼那些傳回此錯誤的表單請求驗證出了什麼問題? </p> <p>如果你知道,請告訴我...我非常感謝您們的任何想法或建議。 </p> <p>謝謝。 </p>

您必須準確指定要驗證的內容:

$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',
]);

我的程式碼範例:

$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_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_kvkk_ok.required' => __('company kvkk ok required'),
        ]);

        if ($validator->fails()) {
            $messages = $validator->messages();
            return json_encode([
                'operation_status' => 'not_validated',
                'request' => $requestData,

            ]);
        }

當你使用 Laravel 的驗證時,你應該讓 Laravel 處理錯誤,因為當規則失敗時,Laravel 會自動拋出例外。 因此,第一個建議是不要在驗證例程中使用 try-catch 區塊。

如 Laravel 文件所述: p>

此外,我建議您不要在控制器中使用驗證,因為根據良好實踐,建議創建單獨的 formRequest 進行驗證,因此您應該稍微修改控制器以包含驗證器類別:

<?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
}

現在您必須建立一個表單請求,也許使用 php artisan make:request UploadVideoRequest# 此命令將在 app/Http/Requests 下建立一個表單請求類,您應將其填充為:

<?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',
        ];
    }

}

透過使用此方法,Laravel 驗證使用者輸入並透過異常管理任何錯誤。

問候。
