Laravel 形成 returns "The given data is invalid" 而我发送替代错误消息
Laravel form returns "The given data is invalid" while I send alternative error messages
我正在一个项目中使用 Laravel 6（包含在这个聊天系统/项目中）。
第一次如此寻找一些东西。
使用带有 PHPStorm 的 xdebug 的调试功能，我可以完美地遵循它。
这是我看到的：
注册控制器：
protected function validator(array $data)
{
$data['name'] = htmlspecialchars($data['name']);
return Validator::make($data, [
'name' => ['required', 'string', 'max:100'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users', 'regex:/^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/'],
'password' => ['required', 'string', 'min:3', 'max:30', 'confirmed', new NoSpaceContaine()],
'min18years' => ['accepted'],
'accept_all_agreements' => ['accepted'],
'medical1' => ['accepted'],
'medical2' => ['accepted']
], [
'name.required' => 'A name is required',
'email.required' => 'An email is required',
'password.required' => 'A password is required',
'min18years.accepted' => 'An approval for min 18 years is required',
'accept_all_agreements.accepted' => 'An approval for agreements is required',
'medical1.accepted' => 'An approval for medical1 is required',
'medical2.accepted' => 'An approval for medical2 is required'
]);
}
$Data（来自调试器，故意未选中 min18years 复选框）：
$data = {array} [9]
_token = "oEMQFjasGoex4MDiThonh8Vw0e5UbyQ5o7GTRAi8"
name = "Peter7"
email = "my7@email.here"
password = "123"
password_confirmation = "123"
min18years = "0"
accept_all_agreements = "yes"
medical1 = "yes"
medical2 = "yes"
Illuminate\Validation\Validator.php:"
public function validate()
{
if ($this->fails()) {
throw new ValidationException($this);
}
return $this->validated();
}
get抛出错误，调用“ValidationException”时的当前数据：
$这个：
$this = {Illuminate\Validation\Validator} [27]
translator = {Illuminate\Translation\Translator} [7]
container = {Illuminate\Foundation\Application} [33]
presenceVerifier = {Illuminate\Validation\DatabasePresenceVerifier} [2]
failedRules = {array} [1]
min18years = {array} [1]
Accepted = {array} [0]
excludeAttributes = {array} [0]
messages = {Illuminate\Support\MessageBag} [2]
messages = {array} [1]
min18years = {array} [1]
0 = "An approval for min 18 years is required"
format = ":message"
data = {array} [9]
_token = "oEMQFjasGoex4MDiThonh8Vw0e5UbyQ5o7GTRAi8"
name = "Peter7"
email = "my7@email.here"
password = "123"
password_confirmation = "123"
min18years = "0"
accept_all_agreements = "yes"
medical1 = "yes"
medical2 = "yes"
initialRules = {array} [7]
rules = {array} [7]
currentRule = "accepted"
implicitAttributes = {array} [0]
implicitAttributesFormatter = null
distinctValues = {array} [0]
after = {array} [0]
customMessages = {array} [7]
name.required = "A name is required"
email.required = "An email is required"
password.required = "A password is required"
min18years.accepted = "An approval for min 18 years is required"
accept_all_agreements.accepted = "An approval for agreements is required"
medical1.accepted = "An approval for medical1 is required"
medical2.accepted = "An approval for medical2 is required"
但是当我跟随对\Illuminate\Validation\ValidationException的调用时。php:
public function __construct($validator, $response = null, $errorBag = 'default')
{
parent::__construct('The given data was invalid.');
$this->response = $response;
$this->errorBag = $errorBag;
$this->validator = $validator;
}
$this 没有收到传递给该函数的消息。
$这个：
$this = {Illuminate\Validation\ValidationException} [12]
validator = null
response = null
status = {int} 422
errorBag = null
redirectTo = null
message = ""
*Exception*string = ""
code = {int} 0
file = "C:\Sources\wachtweken.nl\vendor\laravel\framework\src\Illuminate\Validation\Validator.php"
line = {int} 386
*Exception*trace = {array} [44]
*Exception*previous = null
我希望在执行调试步骤时可以清楚这一点...
按要求添加了验证器函数（但这是默认的：
protected function validator(array $data)
{
$data['name'] = htmlspecialchars($data['name']);
return Validator::make($data, [
'name' => ['required', 'string', 'max:100'],
'email' => ['required', 'string', 'email', 'max:255', 'unique:users', 'regex:/^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z0-9]{2,4}$/'],
'password' => ['required', 'string', 'min:3', 'max:30', 'confirmed', new NoSpaceContaine()],
'min18years' => ['accepted'],
'accept_all_agreements' => ['accepted'],
'medical1' => ['accepted'],
'medical2' => ['accepted']
], [
'name.required' => 'A name is required',
'email.required' => 'An email is required',
'password.required' => 'A password is required',
'min18years.accepted' => 'An approval for min 18 years is required',
'accept_all_agreements.accepted' => 'An approval for agreements is required',
'medical1.accepted' => 'An approval for medical1 is required',
'medical2.accepted' => 'An approval for medical2 is required'
]);
}

你的问题是try/catch。您不必使用它，如果它抛出错误，它将默认 return 返回到它来自的页面 (response()->back()) 输入 (->withInput()) 和验证错误（errors 将被填充以供您在 blade 中使用）。
因此，将您的代码更改为：
public function register(Request $request)
{
$this->validator($request->all())->validate();
event(new Registered($user = $this->create($request->all())));
$this->guard()->login($user);
return $this->registered($request, $user)
?: redirect($this->redirectPath());
}
