根据docs,error messages可以在lang/en/validation.php内部定制，但我收到的错误消息不在文件中:
The password confirmation does not match.
我在失败validation时收到错误消息，因为$request->password_confirmation不同于$request->password:
$request->validate([
'password' => ['required', 'confirmed', Rules\Password::defaults()],
]);
如何自定义错误消息？
$rules = [
'password' => ['required', 'confirmed', Rules\Password::defaults()]
];
$customMessages = [
'password.confirmed' => 'The :attribute does not match' // change it at here
];
$this->validate($request, $rules, $customMessages);
规则confirmed要验证的字段必须有匹配的
{field}_confirmation的领域.
例如，如果正在验证的字段是password，
输入中必须存在匹配的password_confirmation字段.
