使用流明发送电子邮件，而不在 env 文件中设置 smtp 凭据

【中文标题】使用流明发送电子邮件，而不在 env 文件中设置 smtp 凭据

【英文标题】：send email with lumen, without set smtp credential in env file

【发布时间】：2019-04-23 22:07:09

【问题描述】：

我想用 lumen 发送邮件，

我有许多不同的 smtp 凭据，我必须使用 laravel 发送电子邮件，超过 1000 个

所以我无法从 env 文件中设置它。

我必须在每次发送电子邮件之前定义新的凭据。

那么如何在发送邮件之前将其传递给 lumen

因为在 lumen sendMail() 方法中我们可以传递参数数组然后如何管理它。

根据建议，我已覆盖如下代码，

我在 composer.json 文件中使用了以下包，

"illuminate/mail": "^5.2"

然后在命令提示符composer update触发命令

在 bootstrap/app.php 文件中注册类下面，

$app->register('\Illuminate\Mail\MailServiceProvider');

在 cofig 文件夹中创建 mail.php 文件，如下所示，

<?php

在下面更新我的 .env 文件，

MAIL_DRIVER=
MAIL_HOST=
MAIL_PORT=
MAIL_ENCRYPTION=
MAIL_FROM_ADDRESS=
MAIL_FROM_NAME=
MAIL_USERNAME=
MAIL_PASSWORD=

在 bootstrap/app.php 文件中添加 mail.php 文件，如下所示，

$app->configure('mail');

创建一个提供程序以从下面的文件中覆盖方法createSmtpDriver，

vendor\illuminate\mail\TransportManager.php

我创建了如下提供者，

<?php

namespace App\Providers;

use Illuminate\Mail\TransportManager;
use Session;

class EmailServiceProvider extends TransportManager

    /**
     * Create an instance of the SMTP Swift Transport driver.
     *
     * @return \Swift_SmtpTransport
     */
    protected function createSmtpDriver()
    
        $config = $this->app['config']['mail'];

        // The Swift SMTP transport instance will allow us to use any SMTP backend
        // for delivering mail such as Sendgrid, Amazon SES, or a custom server
        // a developer has available. We will just pass this configured host.
        $transport = SmtpTransport::newInstance(
            Session::get('smtp_server'), $config['port']
        );

        if (isset($config['encryption'])) 
            $transport->setEncryption($config['encryption']);
        

        // Once we have the transport we will check for the presence of a username
        // and password. If we have it we will set the credentials on the Swift
        // transporter instance so that we'll properly authenticate delivery.
        if (Session::has('smtp_user') && Session::get('smtp_user')) 
            $transport->setUsername(Session::get('smtp_user'));

            $transport->setPassword(Session::get('smtp_password'));
        

        if (isset($config['stream'])) 
            $transport->setStreamOptions($config['stream']);
        

        return $transport;
    

并在 bootstrap/app.php 文件中添加该提供程序，如下所示，

$app->register(App\Providers\EmailServiceProvider::class);

从现在开始，在所有方法中，都会出现如下错误，

ErrorException in Manager.php line 77:
Missing argument 1 for Illuminate\Support\Manager::createDriver(), called in E:\xampp563\htdocs\delrentals-dashboard-api\vendor\illuminate\support\Manager.php on line 87 and defined

谁能给我建议，我该怎么做才能解决它。

【参考方案1】：

您需要覆盖命名空间 Illuminate\Mail\TransportManager 中的 createSmtpDriver 方法

【讨论】：

如果我将覆盖它并且任何人都会进行作曲家更新，那么它将删除我的代码

它有什么方法可以从我的代码级别而不是供应商覆盖它

是的，您需要创建自己的 MailServiceProvider 版本并在 config/app.php 中替换它。在您的提供者的注册方法中使用您自己的 TransportManager。

嗨，gm，我已经更新了我的问题，其中我有覆盖方法，但是给了我错误，请你看看。

【参考方案2】：

有一种使用多个 smtps 的简单方法。

 public function sendEmails()

    $smtps = Stmp::all();
    foreach ($smtps as $smtp)
    
        config('MAIL_DRIVER', 'smtp');
        config('MAIL_USERNAME', $smtp->username);
        config('MAIL_HOST', $smtp->host);
        config('MAIL_PASSWORD', $smtp->password);
        config('MAIL_PORT', $smtp->port);
        config('MAIL_ENCRYPTION', $smtp->enc);

        //now send mail
        Mail::send('emails.mail', ['data' => $data], function  ($message) use($smtp) 
            $message->to('[e-mail]', 'Tutorials Point')->subject('Laravel');
            $message->from($smtp->from_name, 'Name');
        );
