推荐答案

您可以使用Laravel的 url 验证器

You can use url validator by Laravel

https://laravel.com/docs/5.8/validation#rule-url

'网站'=>'required | url'

或者，如果您想建立更精确的规则，则有几种方法可以执行.其中有一种，我认为最简单:

Or, if you want to build more precise rule, there is a few ways to do it. There is one of them, the simplest in my opinion:

在您的 AppServiceProvider @ boot 中:

Validator::extend('website', function ($attribute, $value, $parameters, $validator) {
  // validation logic, e.g
  return filter_var($value, FILTER_VALIDATE_URL);
});

然后在验证者列表中使用您的规则:

And then use you rule in validators list:

'website' => ['required', 'website'],
