如何在验证器规则中添加上述规则？
我的代码
// 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中遇到了类似的情况，并通过以下方式解决了这个问题。
密码包含以下五个类别中至少三个的字符：
首先，我们需要创建一个正则表达式并对其进行验证。
您的正则表达式如下所示：
^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\x])(?=.*[!$#%]).*$
我已经在this网站上对其进行了测试和验证。然而，以自己的方式执行自己的工作并相应地进行调整。这只是正则表达式的一个例子，你可以按照你想要的方式进行操作。
所以你最后的Laravel代码应该是这样的：
'password' => 'required|
min:6|
regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\X])(?=.*[!$#%]).*$/|
confirmed',
<强>更新 正如@NikK在评论中提到的那样，在Laravel 5.6中，密码值应该封装在数组方括号中，如
'password' => ['required',
'min:6',
'regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\X])(?=.*[!$#%]).*$/',
'confirmed']
我没有在Laravel 5.6上进行测试，所以我相信@NikK因此我现在已经开始使用c＃/ .net，并且没有太多时间用于Laravel。

虽然希望有所帮助，但这与OP的要求不太匹配。借助Laravel，您可以使用以下易于维护的格式定义规则：
$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.',
]
（正则表达式规则默认情况下会共享一条错误消息-即，四个失败的正则表达式规则会导致一条错误消息）

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：

现在你可以使用 Laravel 密码验证了
// 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()
或者你可以将它们全部链接起来
use Illuminate\Validation\Rules\Password;
'password' => [
'required',
'string',
Password::min( 8 )->mixedCase()->numbers()->symbols()->uncompromised(),
'confirmed'
],

自定义Laravel验证规则将使开发人员可以为每个用例提供自定义消息，以获得更好的UX体验。
function copyStyling() {
// This is a standalone script
let masterID = "1107dQEIAbZ8ipBi0wvU6cdy4OV7N2hURT5fjgOwm_vY";
let childID = "1XvGARRBzXofsjrFJkl8SCmt3tQJ2nkw1n9MG3tr9fhU";
// Master Slide Variables
let masterPresentation = SlidesApp.openById(masterID);
let masterSlide = masterPresentation.getSlides()[0];
let masterElements = masterSlide.getPageElements();
// Get style elements
let masterBackground = masterSlide.getBackground();
let masterSolidFill = masterBackground.getSolidFill().getColor();
// etc
// ...
// Child Slide Variables
let childPresentation = SlidesApp.openById(childID);
let childSlide = childPresentation.getSlides()[0];
let childElements = childSlide.getPageElements();
// Updating the stylings for the page
let childBackground = childSlide.getBackground();
childBackground.setSolidFill(masterSolidFill);
// etc
// ...
// Updating the stylings for each element on the page
masterElements.forEach((element, i) => {
childElements[i].setLeft(element.getLeft());
childElements[i].setTop(element.getTop());
// etc
// ...
});
}
php artisan make:rule IsValidPassword然后根据您的要求进行验证：
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
*/

* 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

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

使用 laravel 8 很容易做到：
$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）。
