通过电子邮件验证电子邮件 :rfc, dns 的 Laravel faker 电子邮件

Question

我明白了

invalid email address

当使用 faker 填充我的应用程序的电子邮件字段时。

'email' => ['required', 'email:rfc,dns']

有没有办法让 faker 吐出通过这些测试的有效电子邮件地址？

我尝试了 safeEmail 和其他一些，但它们仍然失败

Answer 1

我有同样的问题，它都与 Laravel 用来验证电子邮件的 Egulias\EmailValidator\Validation\DNSCheckValidation 类有关(如您所见 here example 是保留的顶级域)。

无法避免使用 faker 创建的电子邮件通过此验证，IMO，这是应该的。但是我们需要进行测试，不是吗？

有一个简单的方法(也可以在 FormRequest 或任何你正在使用的实现验证器的方法中使用):

// In your test:
$this->post('my-url', ['email' => $this->faker->unique()->safeEmail])

// In your code
$emailRules = 'email:rfc';

if(!app()->runningUnitTests()) {
    $emailRules .= ',dns';
}

$validator = Validator::make($data, ['email' => ['required', $emailRules]]);
// [...]

另一种方法是创建一个自定义的电子邮件验证规则来封装 runningUnitTests 逻辑(我认为它更简洁)

<?php

namespace App\Rules;

use Egulias\EmailValidator\EmailValidator;
use Egulias\EmailValidator\Validation\DNSCheckValidation;
use Egulias\EmailValidator\Validation\MultipleValidationWithAnd;
use Egulias\EmailValidator\Validation\NoRFCWarningsValidation;
use Egulias\EmailValidator\Validation\RFCValidation;
use Egulias\EmailValidator\Validation\SpoofCheckValidation;
use Illuminate\Contracts\Validation\Rule;
use Illuminate\Validation\Concerns\FilterEmailValidation;

/** @codeCoverageIgnore */
class ValidEmail implements Rule
{
    protected array $parameters;

    /**
     * Create a new rule instance.
     *
     * @return void
     */
    public function __construct(array $parameters = [])
    {
        $this->parameters = $parameters;
    }

    /**
     * Determine if the validation rule passes.
     *
     * @param  string  $attribute
     * @param  mixed  $value
     * @return bool
     */
    public function passes($attribute, $value)
    {
        if (! is_string($value) && ! (is_object($value) && method_exists($value, '__toString'))) {
            return false;
        }

        $validations = collect($this->parameters)
            ->unique()
            ->map(function ($validation) {
                if ($validation === 'rfc') {
                    return new RFCValidation();
                } elseif ($validation === 'strict') {
                    return new NoRFCWarningsValidation();
                } elseif ($validation === 'dns' && !app()->runningUnitTests()) {
                    return new DNSCheckValidation();
                } elseif ($validation === 'spoof') {
                    return new SpoofCheckValidation();
                } elseif ($validation === 'filter') {
                    return new FilterEmailValidation();
                }

                return null;
            })
            ->values()
            ->filter()
            ->all() ?: [new RFCValidation()];

        return (new EmailValidator)->isValid($value, new MultipleValidationWithAnd($validations));
    }

    /**
     * Get the validation error message.
     *
     * @return string
     */
    public function message()
    {
        return __('validation.email');
    }
}

比在你的代码中:

$validator = Validator::make($data, ['email' => ['required', new ValidEmail()]]);

// OR

$validator = Validator::make($data, ['email' => ['required', new ValidEmail(['rfc','filter','dns'])]]);
// [...]
