如何在验证器中添加密码验证规则?
验证规则:
密码至少包含以下5个类别中的3个字符:
- 英文大写字符(A - Z)
- 小写英文字符(a - z)
- 进制10位(0 - 9)
- 非字母数字(例如:!、$、#或%) Unicode字符
如何在验证器规则中添加上述规则?
My Code Here
// 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中遇到过类似的情况，并通过以下方式解决了它。
密码至少包含以下5个类别中的3个字符:
- 英文大写字符(A - Z)
- 小写英文字符(a - z)
- 进制10位(0 - 9)
- 非字母数字(例如:!、$、#或%) Unicode字符
首先，我们需要创建一个正则表达式并验证它。
你的正则表达式看起来像这样:
^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*['d'x])(?=.*[!$#%]).*$
我已经在这个网站上测试和验证了它。然而，以你自己的方式执行你自己的，并相应地调整。这只是一个正则表达式的例子，你可以按你想要的方式操作。
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'
]
注意:
- 我已经在正则表达式站点和Laravel 5测试环境中测试和验证了它，并且它有效。
- 我已经使用了min:6，这是可选的，但是有一个反映不同方面的安全策略总是一个很好的做法，其中之一是最小密码长度。
- 我建议您使用密码确认，以确保用户输入正确的密码 在6个字符内，我们的正则表达式应该包含至少3个a-z或a-z，数字和特殊字符。
- 在进入生产环境之前，一定要在测试环境中测试代码。
- 我在这个答案中所做的只是一个正则密码 的例子

这并不完全符合OP的要求，尽管希望它能有所帮助。使用Laravel，你可以用一种易于维护的格式来定义你的规则，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() );
}
将输出:
[
'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导致一条错误消息)
从Laravel版本8开始，你可以使用内置的密码验证:
// 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。
php artisan make:rule IsValidPassword
namespace 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.';
}
}
}
然后在您的请求验证:
$request->validate([
'email' => 'required|string|email:filter',
'password' => [
'required',
'confirmed',
'string',
new isValidPassword(),
],
]);
听起来像是正则表达式的好工作。
Laravel验证规则支持正则表达式。两个4。X和5。X版本支持它:
- 4.2: http://laravel.com/docs/4.2/validation#rule-regex
- 5.1: http://laravel.com/docs/5.1/validation#rule-regex
这可能也有帮助:
http://www.regular-expressions.info/unicode.html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()
],
);
请参阅文档，(在您的情况下，您可以忽略未妥协规则)
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,}$/',
]);
