PHP框架怎么进行数据验证_PHP框架验证器规则与错误信息处理

public function store(Request $request)
{
    $validated = $request->validate([
        'name' => 'required|string|max:255',
        'email' => 'required|email|unique:users',
        'age' => 'nullable|integer|min:18'
    ]);

    // 验证通过后执行逻辑
}

use Symfony\Component\Validator\Constraints as Assert;

$constraints = new Assert\Collection([
    'name'  => new Assert\Length(['min' => 1, 'max' => 255]),
    'email' => [new Assert\Email(), new Assert\NotBlank()],
]);

$request->validate([
    'email' => 'required|email',
    'password' => 'required|min:6'
], [
    'email.required' => '邮箱不能为空',
    'email.email' => '请输入有效的邮箱地址',
    'password.min' => '密码至少6位'
]);

try {
    $validated = $request->validate([...]);
} catch (ValidationException $e) {
    return redirect()->back()->withErrors($e->errors());
}

php artisan make:request StoreUserRequest

public function rules()
{
    return [
        'name' => 'required|string|max:100',
        'email' => 'required|email|unique:users,email',
    ];
}

public function messages()
{
    return [
        'name.required' => '姓名必填',
        'email.unique' => '该邮箱已被注册'
    ];
}
