如何在验证器规则中添加上述规则？
我的代码在这里
// create the validation rules ------------------------
$rules = array(
'name' => 'required', // just a normal required validation
'email' => 'required|email|unique:ducks', // required and must be unique in the ducks table
'password' => 'required',
'password_confirm' => 'required|same:password' // required and has to match the password field
);
// do the validation ----------------------------------
// validate against the inputs from our form
$validator = Validator::make(Input::all(), $rules);
// check if the validator failed -----------------------
if ($validator->fails()) {
// get the error messages from the validator
$messages = $validator->messages();
// redirect our user back to the form with the errors from the validator
return Redirect::to('home')
->withErrors($validator);
}
我在 Laravel 中也遇到过类似的情况，并通过以下方式解决了它。
密码包含以下五类中至少三类的字符：
首先，我们需要创建一个正则表达式并验证它。
您的正则表达式将如下所示：
^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$
我已在 this 网站上对其进行了测试和验证。然而，以你自己的方式表现你自己，并相应地调整。这只是正则表达式的一个示例，您可以按照您想要的方式进行操作。
所以你最终的 Laravel 正则表达式规则 应该是这样的：
'password' => [
'required',
'min:6',
'regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$/',
'confirmed'
]
注：
关于 Laravel 中正则表达式规则的自定义验证消息，可以查看以下几个链接：
这与 OP 要求不太相符，但希望它有所帮助。使用 Laravel，您可以以易于维护的格式定义规则，如下所示：
$inputs = [
'email' => 'foo',
'password' => 'bar',
];
$rules = [
'email' => 'required|email',
'password' => [
'required',
'string',
'min:10', // must be at least 10 characters in length
'regex:/[a-z]/', // must contain at least one lowercase letter
'regex:/[A-Z]/', // must contain at least one uppercase letter
'regex:/[0-9]/', // must contain at least one digit
'regex:/[@$!%*#?&]/', // must contain a special character
],
];
$validation = \Validator::make( $inputs, $rules );
if ( $validation->fails() ) {
print_r( $validation->errors()->all() );
}
会输出：
[
'The email must be a valid email address.',
'The password must be at least 10 characters.',
'The password format is invalid.',
]
（默认情况下，正则表达式规则共享一条错误消息，即四个失败的正则表达式规则会导致一条错误消息）
自 Laravel 版本 8 起，您可以使用内置密码验证：
// Require at least 8 characters...
Password::min(8)
// Require at least one letter...
Password::min(8)->letters()
// Require at least one uppercase and one lowercase letter...
Password::min(8)->mixedCase()
// Require at least one number...
Password::min(8)->numbers()
// Require at least one symbol...
Password::min(8)->symbols()
或者你可以把它们全部链接起来
use Illuminate\Validation\Rules\Password;
$rules = [
'password' => [
'required',
'string',
Password::min(8)
->mixedCase()
->numbers()
->symbols()
->uncompromised(),
'confirmed'
],
]
自定义 Laravel 验证规则将允许开发人员为每个用例提供自定义消息，以获得更好的用户体验体验。
php artisan make:rule IsValidPasswordnamespace App\Rules;
use Illuminate\Support\Str;
use Illuminate\Contracts\Validation\Rule;
class isValidPassword implements Rule
{
/**
* Determine if the Length Validation Rule passes.
*
* @var boolean
*/
public $lengthPasses = true;
/**
* Determine if the Uppercase Validation Rule passes.
*
* @var boolean
*/
public $uppercasePasses = true;
/**
* Determine if the Numeric Validation Rule passes.
*
* @var boolean
*/
public $numericPasses = true;
/**
* Determine if the Special Character Validation Rule passes.
*
* @var boolean
*/
public $specialCharacterPasses = true;
/**
* Determine if the validation rule passes.
*
* @param string $attribute
* @param mixed $value
* @return bool
*/
public function passes($attribute, $value)
{
$this->lengthPasses = (Str::length($value) >= 10);
$this->uppercasePasses = (Str::lower($value) !== $value);
$this->numericPasses = ((bool) preg_match('/[0-9]/', $value));
$this->specialCharacterPasses = ((bool) preg_match('/[^A-Za-z0-9]/', $value));
return ($this->lengthPasses && $this->uppercasePasses && $this->numericPasses && $this->specialCharacterPasses);
}
/**
* Get the validation error message.
*
* @return string
*/
public function message()
{
switch (true) {
case ! $this->uppercasePasses
&& $this->numericPasses
&& $this->specialCharacterPasses:
return 'The :attribute must be at least 10 characters and contain at least one uppercase character.';
case ! $this->numericPasses
&& $this->uppercasePasses
&& $this->specialCharacterPasses:
return 'The :attribute must be at least 10 characters and contain at least one number.';
case ! $this->specialCharacterPasses
&& $this->uppercasePasses
&& $this->numericPasses:
return 'The :attribute must be at least 10 characters and contain at least one special character.';
case ! $this->uppercasePasses
&& ! $this->numericPasses
&& $this->specialCharacterPasses:
return 'The :attribute must be at least 10 characters and contain at least one uppercase character and one number.';
case ! $this->uppercasePasses
&& ! $this->specialCharacterPasses
&& $this->numericPasses:
return 'The :attribute must be at least 10 characters and contain at least one uppercase character and one special character.';
case ! $this->uppercasePasses
&& ! $this->numericPasses
&& ! $this->specialCharacterPasses:
return 'The :attribute must be at least 10 characters and contain at least one uppercase character, one number, and one special character.';
default:
return 'The :attribute must be at least 10 characters.';
}
}
}
然后根据您的请求验证：
$request->validate([
'email' => 'required|string|email:filter',
'password' => [
'required',
'confirmed',
'string',
new isValidPassword(),
],
]);
对于正则表达式来说听起来不错。
Laravel 验证规则支持正则表达式。 4.X 和 5.X 版本都支持它:
这也可能有帮助：
使用 laravel 8 很容易做到这一点：
$rules = array(
'name' => ['required'],
'email' => ['required','email','unique:ducks'],
'password' => ['required', 'confirmed',Password::min(8)
->letters()
->mixedCase()
->numbers()
->symbols()
->uncompromised()
],
);
请参阅doc，（在您的情况下，您可以忽略不妥协的规则）。
laravel 9 password validation
$request->validate([
'name' => 'required', 'string', 'max:255',
'email' => 'required', 'string', 'email', 'max:255', 'unique:users',
'password' => 'required|string|min:6|confirmed|regex:/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{6,}$/',
]);
