Implementing Password Strength Validation in Laravel with schuppo/password-strength

Requirement: In Laravel, allow users to specify password strength rules such as requiring at least one letter, case‑sensitive letters, numbers, or symbols, either combined or individually.

Install the package from Packagist (schuppo/password-strength) via Composer. For Laravel 6+ use composer require schuppo/password-strength:"~2.0"; for Laravel 5 use composer require schuppo/password-strength:"~1.5".

Copy the language lines into your project's resources/lang/.../validation.php file:

"letters" => ":attribute 必须包含至少一个字母。",
"case_diff" => ":attribute 必须包含大小写字母。",
"numbers" => ":attribute 必须包含至少一个数字。",
"symbols" => ":attribute 必须包含至少一个符号。"

Use the custom rules in a validator, for example requiring a password of at least six characters, containing both lower‑ and upper‑case letters and at least one digit:

public function post(Request $request){
    $validator = Validator::make($request->all(), [
        'name' => 'bail',
        'password' => ['bail','required','min:6','case_diff','numbers']
    ]);
    if ($validator->fails()) {
        return $validator->errors()->first();
    }
    return '正确';
}
