Laravel：如何对请求使用多个验证规则

我有两个模型用户和配置文件一切工作正常并完美创建记录。为了进行验证，我创建了如下请求类。用户请求我有两个模型User和Profile一切工作正常并完美创造记录。为了验证，我创建了如下请求类。用户请求 <?php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; use Illuminate\Support\Facades\Validator; use function __; use function preg_match; class UserRequest extends FormRequest { /** * Determine if the user is authorized to make this request. * * @return bool * @todo set role based permission for the method * */ public function authorize() { return TRUE; } /** * Get the validation rules that apply to the request. * * @return array */ public function rules() { Validator::extend( 'without_spaces', function ($attr, $value) { return preg_match('/^\S*$/u', $value); }, __('validation.username_space') ); switch ($this->method()) { case 'POST': return [ 'username' => 'required|string|without_spaces|max:255|unique:users', 'email' => 'required|string|email|max:255|unique:users,email', 'password' => 'required|string|min:8|confirmed', 'role' => 'required', ]; case 'PUT': case 'PATCH': return [ 'username' => 'sometimes|required|string|without_spaces|max:255|unique:users,username,' . $this->user->id, 'email' => 'required|string|email|max:255|unique:users,email,' . $this->user->id, 'password' => 'nullable|string|min:8|confirmed', 'role' => 'required', ]; case 'GET': case 'DELETE': default: return []; break; } } } 个人资料请求 <?php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; use Illuminate\Validation\Rule; use function __; use function preg_match; class ProfileRequest extends FormRequest { /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize() { return FALSE; } /** * Get the validation rules that apply to the request. * * @return array */ public function rules() { Validator::extend('unique_field', function ($attributes, $value, $parameters, $validator) { return; }, __('validation.username_space') ); switch ($this->method()) { case 'POST': case 'PUT': case 'PATCH': return [ 'first_name' => 'max:20', 'last_name' => 'max:20', 'mobile' => 'regex:/(01)[0-9]{9}/|digits:8 ', 'city' => 'max:30', 'facebook' => 'url', 'twitter' => 'url', 'youtube' => 'url', 'instagram' => 'url', ]; case 'GET': case 'DELETE': default: return []; break; } } } 用户控制器 public function store(UserRequest $request) { // begin transaction DB::beginTransaction(); try { // create user $user = User::create([ 'username' => $request->username, 'email' => $request->email, 'password' => Hash::make($request->password), 'role' => $request->role, ]); // set profile data $profile = new Profile([ 'first_name' => $request->first_name, 'last_name' => $request->last_name, 'mobile' => $request->mobile, 'city' => $request->city, 'facebook' => $request->facebook, 'twitter' => $request->twitter, 'youtube' => $request->youtube, 'instagram' => $request->instagram, ]); // save profile data $user->profile()->save($profile); // commit transaction DB::commit(); // if user created if ($user) { return redirect(route('admin.users.index'))->with('success', __('messages.admin.feedback.user_created')); } else { return redirect(route('admin.users.index'))->with('error', __('messages.admin.feedback.user_created')); } } catch (Throwable $exception) { // rollback if error DB::rollBack(); throw $exception; } } public function update(UserRequest $request, User $user) { try { $user->email = $request->email; $user->role = $request->role; if ($request->has('password')) { $user->password = Hash::make($request->password); } $user->save(); // set profile data $profile = [ 'first_name' => $request->first_name, 'last_name' => $request->last_name, 'mobile' => $request->mobile, 'city' => $request->city, 'facebook' => $request->facebook, 'twitter' => $request->twitter, 'youtube' => $request->youtube, 'instagram' => $request->instagram, ]; // save profile data $user->profile()->update($profile); return redirect(route('admin.users.index'))->with('success', __('messages.admin.feedback.user_updated')); } catch (Throwable $exception) { throw $exception; } } 问题：我有一张用于用户字段和个人资料字段的表单。现在我不知道如何在方法中使用两个请求类来验证字段。我找到了解决方法。在 ProfileRequest 和 store 方法中键入 update 类，并用它来验证配置文件字段。用户控制器 public function store(UserRequest $request, ProfileRequest $profileRequest) { // begin transaction DB::beginTransaction(); try { // create user $user = User::create([ 'username' => $request->username, 'email' => $request->email, 'password' => Hash::make($request->password), 'role' => $request->role, ]); // set profile data $profile = new Profile([ 'first_name' => $profileRequest->first_name, 'last_name' => $profileRequest->last_name, 'mobile' => $profileRequest->mobile, 'city' => $profileRequest->city, 'facebook' => $profileRequest->facebook, 'twitter' => $profileRequest->twitter, 'youtube' => $profileRequest->youtube, 'instagram' => $profileRequest->instagram, ]); // save profile data $user->profile()->save($profile); // commit transaction DB::commit(); // if user created if ($user) { return redirect(route('admin.users.index'))->with('success', __('messages.admin.feedback.user_created')); } else { return redirect(route('admin.users.index'))->with('error', __('messages.admin.feedback.user_created')); } } catch (Throwable $exception) { // rollback if error DB::rollBack(); throw $exception; } } public function update(UserRequest $request, ProfileRequest $profileRequest, User $user) { try { $user->email = $request->email; $user->role = $request->role; if ($request->has('password')) { $user->password = Hash::make($request->password); } $user->save(); // set profile data $profile = [ 'first_name' => $profileRequest->first_name, 'last_name' => $profileRequest->last_name, 'mobile' => $profileRequest->mobile, 'city' => $profileRequest->city, 'facebook' => $profileRequest->facebook, 'twitter' => $profileRequest->twitter, 'youtube' => $profileRequest->youtube, 'instagram' => $profileRequest->instagram, ]; // save profile data $user->profile()->update($profile); return redirect(route('admin.users.index'))->with('success', __('messages.admin.feedback.user_updated')); } catch (Throwable $exception) { throw $exception; } } 在 UserRequest 类中，您可以将它们分配给一个数组，而不是直接从 switch 语句返回规则。为了我们的目的，我们称其为 $rules。然后您应该能够合并您的个人资料中的规则，返回合并的规则，如下所示： $profileRequest = new ProfileRequest(); // you may need to switch this to app()->make(ProfileRequest::class) if you get an error instantiating this return array_merge($rules, $profileRequest->rules());
