Magento2销售发票电子邮件未发送

Magento2 运行环境条件

Magento 2.3.1
OS: Ubuntu 16.04
Mysql version 5.7.21
PHP version 7.0.22

Steps to reproduce

Set up “Stores -> Settings -> Configuration -> Sales -> Sales Emails -> Invoice -> Enabled -> Yes”
Configure PayPal “Stores -> Settings -> Configuration -> Sales -> Payment Methods -> PayPal -> Payment Action -> Sale”
Make order and pay with PayPal.

Expected result

Order Created
Email with order information send.
Invoice Created
Email with invoice information send

Actual result

Order Created <- ok
Email with order information send. <- ok
Invoice Created <- ok
Email with invoice information is not send <- wrong

Magento CE 2.3.1 使用Paypal付款之后，未发送发票电子邮件，经过仔细分析是因为Magento 开发团队只做了订单邮件发送，未做发票发送，该功能已经在magento CE 2.3.4 的 Vendor /magento/module-quote/Observer/SubmitObserver 中修复。

在Magento 2.3.1 Vendor /magento/module-quote/Observer/SubmitObserver 中只有订单邮件发送代码如下：

 public function execute(\Magento\Framework\Event\Observer $observer)
    {
        /** @var  \Magento\Quote\Model\Quote $quote */
        $quote = $observer->getEvent()->getQuote();
        /** @var  \Magento\Sales\Model\Order $order */
        $order = $observer->getEvent()->getOrder();

        /**
         * a flag to set that there will be redirect to third party after confirmation
         */
        $redirectUrl = $quote->getPayment()->getOrderPlaceRedirectUrl();
        if (!$redirectUrl && $order->getCanSendNewEmailFlag()) {
            try {
                $this->orderSender->send($order);
            } catch (\Exception $e) {
                $this->logger->critical($e);
            }
        }
    }
}

在Magento 2.3.4 Vendor /magento/module-quote/Observer/SubmitObserver 中发送订单和发票邮件代码如下：

 public function execute(Observer $observer)
    {
        /** @var  Quote $quote */
        $quote = $observer->getEvent()->getQuote();
        /** @var  Order $order */
        $order = $observer->getEvent()->getOrder();

        /**
         * a flag to set that there will be redirect to third party after confirmation
         */
        $redirectUrl = $quote->getPayment()->getOrderPlaceRedirectUrl();
        if (!$redirectUrl && $order->getCanSendNewEmailFlag()) {
            try {
                $this->orderSender->send($order);
                $invoice = current($order->getInvoiceCollection()->getItems());
                if ($invoice) {
                    $this->invoiceSender->send($invoice);
                }
            } catch (\Exception $e) {
                $this->logger->critical($e);
            }
        }
    }

那么在Magento2.3.1中怎么解决发送发票邮件呢

在这里我们重新定义模块，使用magento2的事件分发机制，来解决该问题。

重新创建模块ChuWu_AutoInvoiceEmail

第一步：创建文件夹ChuWu/AutoInvoiceEmail /etc,并在etc文件夹里面添加module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="ChuWu_AutoInvoiceEmail" setup_version="1.0.0">
    </module>
</config>

第二步：在文件夹ChuWu/AutoInvoiceEmail /下面,创建 registration.php 文件并添加如下代码。

<?php

\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'ChuWu_AutoInvoiceEmail',
    __DIR__
);

第三步：在文件夹ChuWu/AutoInvoiceEmail /etc下面创建events.xml文件，并添加如下代码。

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="sales_model_service_quote_submit_success">
        <observer name="chuwu_autoinvoiceemail_send" instance="ChuWu\AutoInvoiceEmail\Observer\InvoiceEmailObserver" />
    </event>
</config>

第四步：在文件夹ChuWu/AutoInvoiceEmail /文件夹下面创建Observer文件夹并在该文件夹里面创建InvoiceEmailObserver.php文件

/app/code/ChuWu/AutoInvoiceEmail/Observer/InvoiceEmailObserver.php

第五步：在InvoiceEmailObserver.php添加如下代码：

<?php

/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */

namespace ChuWu\AutoInvoiceEmail\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Quote\Model\Quote;
use Magento\Sales\Model\Order;
use Magento\Sales\Model\Order\Email\Sender\InvoiceSender;
use Magento\Sales\Model\Order\Email\Sender\OrderSender;
use Psr\Log\LoggerInterface;

use ChuWu\Test\Helper\Data as CCData;


/**
 * Class responsive for sending order and invoice emails when it's created through storefront.
 */
class InvoiceEmailObserver implements ObserverInterface
{
    /**
     * @var LoggerInterface
     */
    private $logger;

    /**
     * @var OrderSender
     */
    private $orderSender;

    /**
     * @var InvoiceSender
     */
    private $invoiceSender;

    /**
     * @var CCData
     */
    private $ccHelper;

    /**
     * @param LoggerInterface $logger
     * @param OrderSender $orderSender
     * @param InvoiceSender $invoiceSender
     * @param CCData $ccHelper
     */
    public function __construct(
        LoggerInterface $logger,
        OrderSender $orderSender,
        InvoiceSender $invoiceSender,
        CCData $ccHelper
    )
    {
        $this->logger = $logger;
        $this->orderSender = $orderSender;
        $this->invoiceSender = $invoiceSender;
        $this->ccHelper = $ccHelper;
    }

    /**
     * Send order and invoice email.
     *
     * @param Observer $observer
     *
     * @return void
     */
    public function execute(Observer $observer)
    {
        /** @var  Quote $quote */
        $quote = $observer->getEvent()->getQuote();
        /** @var  Order $order */
        $order = $observer->getEvent()->getOrder();

        /**
         * a flag to set that there will be redirect to third party after confirmation
         */
        $redirectUrl = $quote->getPayment()->getOrderPlaceRedirectUrl();
        if (!$redirectUrl && $order->getCanSendNewEmailFlag()) {
            try {
                //记录重复发送订单邮件的日志
               $this->ccHelper->LogData('the second send order email:',[]);
               //$this->orderSender->send($order);
                $invoice = current($order->getInvoiceCollection()->getItems());
                if ($invoice) {
                    $this->invoiceSender->send($invoice);
                    //记录发票邮件发送日志
                    $this->ccHelper->LogData('发送发票邮寄:',[]);
                }else{
                    //记录没有生成发票，不发送发票邮件
                    $this->ccHelper->LogData('没有创建发票信息:',[]);
                }
            } catch (\Exception $e) {
                $this->logger->critical($e);
            }
        }
    }
}

在该代码里面需要注释掉 // $this->orderSender->send($order); 发送订单邮件功能，或者不写，如果不这样操作。订单邮件将会多发送一封邮件，因为之前的事件机制调用过订单发送邮件的功能，再调用就重复发送了。

第六步：代码保存上传并执行下面的命令行操作：

php bin/magento setup:upgrade
php bin/magento setup:di:compile

第七步：使用paypal支付下单测试，在这里paypal配置Payment Action 的参数为Sale.如果是Authorization 则不会生成发票更不会发送邮件，这个时候需要网站管员在订单后台手动创建发票，并发送发票邮件。

第八步：支付测试，收到下面邮件，并记录日志文件如下：

[2021-01-28 08:03:41] customLogger.INFO: the second send order email: [] []
[2021-01-28 08:03:45] customLogger.INFO: send  invoice email: [] []

但是查看邮件的收件列表，发现一个问题，发票邮件先发送，订单邮件后发送。

分析原因是magento2先执行了我写的事件，后执行magento2自身的事件。我在想有没有什么办法，设置事件的执行顺序呢。
