This depends on where you are catching the exception.
这取决于您在哪里捕获异常。
Sentry does not use the Validator class. So if you want to return an error message the Laravel way, you should create a separate Validator object and validate first, then only pass to Sentry after your validation has passed.
Sentry 不使用 Validator 类。因此，如果您想以 Laravel 的方式返回错误消息，您应该创建一个单独的 Validator 对象并首先进行验证，然后在您的验证通过后才传递给 Sentry。
Sentry will only be able to pass 1 error back as it is catching a specific exception. Furthermore, the error will not be of the same type as the error in the validation class.
Sentry 只能将 1 个错误传回，因为它正在捕获特定的异常。此外，错误将与验证类中的错误类型不同。
Also, if Sentry does catch the exception, then your Validation is clearly not working.
此外，如果 Sentry 确实捕获了异常，那么您的验证显然不起作用。
Code below is not how you should do it, but more to show a combination of what I believe shows ways of working with Laravel / Sentry
下面的代码不是你应该怎么做，而是更多地展示了我认为展示了使用 Laravel / Sentry 的方式的组合
Example User model
示例用户模型
class User extends Eloquent {
public $errors;
public $message;
public function registerUser($input) {
$validator = new Validator::make($input, $rules);
if $validtor->fails() {
$this->errors = $validator->messages();
return false;
}
try {
// Register user with sentry
return true;
}
catch (Cartalyst\Sentry\Users\LoginRequiredException $e)
{
$this->message = "failed validation";
return false;
}
}
}
}
UserController
用户控制器
class UserController extends BaseController {
public function __construct (User $user) { $this->user = $user; }
public function postRegister()
{
$input = [
'email' => Input::get('email'),
'password' => Input::get('password'),
'password_confirmation' => Input::get('password_confirmation')
];
if ($this->user->registerUser($input)) {
Session::flash('success', 'You have successfully registered. Please check email for activation code.');
return Redirect::to('/');
}
else {
Session::flash('error', $this->user->message);
return Redirect::to('login/register')->withErrors($this->user->errors)->withInput();
}
}
