错误消息：预期响应代码 220 但得到空响应”，异常 "Swift_TransportException"，

Question

I am following a tutorial to build an API using passport authentication on enter link description here 我已经完成了第 1 部分并通过 帐户确认和通知 完成了第 2 部分，但是当我在 POSTMAN 上进行测试时最终遇到了问题。问题是，它确实只是在没有发送错误邮件的情况下才添加到数据库中。我不知道我需要在 .env 或 mail.php 中做任何配置。当我尝试配置电子邮件地址、STMP 和密码时。再次显示相同的错误，我在这里看到的大多数问题都非常不同，因为大多数问题都与 mail.php 和 .env 有关，我不知道，因为教程 link 上没有这样的问题，我甚至试图改变 mail.php 和 .env，我运行 php artisan cache:clear 但显示相同的错误。

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;

class SignupActivate extends Notification
{
    use Queueable;

    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Get the notification's delivery channels.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return ['mail'];
    }

    /**
     * Get the mail representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return \Illuminate\Notifications\Messages\MailMessage
     */
    public function toMail($notifiable)
{
    $url = url('/api/auth/signup/activate/'.$notifiable->activation_token);
    return (new MailMessage)
        ->subject('Confirm your account')
        ->line('Thanks for signup! Please before you begin, you must confirm your account.')
        ->action('Confirm Account', url($url))
        ->line('Thank you for using our application!');
}
    /**
     * Get the array representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function toArray($notifiable)
    {
        return [
            //
        ];
    }
}

我也做过，两种方式认证 Mail.php

return [

'driver' => env('MAIL_DRIVER', 'smtp'),

'host' => env('MAIL_HOST', 'smtp.gmail.com'),

'port' => env('MAIL_PORT', 587),

'from' => [
    'address' => env('MAIL_FROM_ADDRESS', 'username@gmail.com'),
    'name' => env('MAIL_FROM_NAME', 'Payne Curtis'),
],

'encryption' => env('MAIL_ENCRYPTION', 'tls'),

'username' => env('MAIL_USERNAME'),

'password' => env('MAIL_PASSWORD'),


'sendmail' => '/usr/sbin/sendmail -bs',

'markdown' => [
    'theme' => 'default',

    'paths' => [
        resource_path('views/vendor/mail'),
    ],
],

'log_channel' => env('MAIL_LOG_CHANNEL'),

];

.env

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=username@gmail.com
MAIL_PASSWORD=XXXXXXXXXXXXXXX
MAIL_ENCRYPTION=null

我想我可以在这里解决您的问题。您需要做的是严格设置以符合 mail.php

return [

'driver' => env('MAIL_DRIVER', 'smtp'),

'host' => env('MAIL_HOST', 'smtp.gmail.com'),

'port' => env('MAIL_PORT', 587),

'from' => [
    'address' => env('MAIL_FROM_ADDRESS', 'username@gmail.com'),
    'name' => env('MAIL_FROM_NAME', 'Payne Curtis'),
],

'encryption' => env('MAIL_ENCRYPTION', 'tls'),

'username' => env('MAIL_USERNAME'),

'password' => env('MAIL_PASSWORD'),


'sendmail' => '/usr/sbin/sendmail -bs',

'markdown' => [
    'theme' => 'default',

    'paths' => [
        resource_path('views/vendor/mail'),
    ],
],

'log_channel' => env('MAIL_LOG_CHANNEL'),
];

因此将您的 .env 更改为以下内容；

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=abdulkabirojulari@gmail.com
MAIL_PASSWORD=gjcltiocmmqoutfi
MAIL_ENCRYPTION=tls

MAIL_ENCRYPTION=tls非常必要，需要添加到.env文件中
