如何在 Magento 2.4 中发送带附件的电子邮件

Question

我是万磁王的新手。我在网上搜索并尝试了不同的解决方案，但没有奏效。我有一个观察者，每当客户下订单时，我都会从中生成 CSV 文件。我正在使用 来触发它。现在我想添加代码以将生成的 CSV 文件作为附件发送给客户。在 Magento 2.4 中执行此操作的方法是什么。我在网上找到的解决方案不起作用。我想在这个文件的execute(\Magento\Framework\Event\Observer $observer)函数中添加代码。

    public function __construct(
        \Magento\Framework\App\RequestInterface $request,
        \Magento\Sales\Model\Order $order,
        \Magento\Framework\App\Response\Http\FileFactory $fileFactory,
        Filesystem $filesystem,
        \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig,
        \Magento\Customer\Model\Customer $customer,
        \Magento\Store\Model\StoreManagerInterface $storemanager,

        \Magento\Checkout\Model\Session $checkoutSession,
        \Magento\Sales\Model\OrderFactory $orderFactory,
        \Magento\Framework\ObjectManager\ObjectManager $objectManager,

        
        \Psr\Log\LoggerInterface $logger,
        \Magento\Catalog\Model\ProductFactory $productFactory,

        \Magento\Catalog\Model\ProductRepository $productRepository

    ) { 
        $this->_scopeConfig = $scopeConfig;
        $this->_customer = $customer;
        $this->_storemanager = $storemanager;
        $this->_request = $request;
        $this->_order = $order;
        $this->_fileFactory = $fileFactory;
        $this->directory = $filesystem->getDirectoryWrite(DirectoryList::VAR_DIR);
        $this->_productRepository = $productRepository;

    }
 
    public function execute(\Magento\Framework\Event\Observer $observer) {
        
        
        
        $order = $observer->getEvent()->getOrder();
    

 
        $websiteID = $this->_storemanager->getStore()->getWebsiteId();

        
        $headers = array('Company Name', 'Contact Name', 'Contact Email', 'Contact Phone','Shipping Address' ,'SKU','QTY','Price','Total','Weight');

           
                
            
            $name = strtotime('now');
            $file = 'customorderexport/'.$name.'_detailed_orderexport.csv';
            $this->directory->create('customorderexport');
            $stream = $this->directory->openFile($file, 'w+');
            $stream->lock();
            $stream->writeCsv($headers);
            
            $orderdetail['Company Name'] = "";
            $orderdetail['Contact Name'] = $order->getCustomerName();
            $orderdetail['Contact Email'] = $order->getCustomerEmail();
            $orderdetail['Contact Phone'] = $order->getShippingAddress()->getTelephone();

            $streetadd = $order->getShippingAddress()->getStreet();
            
            $orderdetail['Shipping Address'] = $streetadd[0];



            $items = $order->getAllItems();
            foreach ($items as $item) {
            
                $orderdetail['SKU'] = $item->getSKU();              
                $orderdetail['QTY'] = $item->getQtyOrdered();
                $orderdetail['Price'] = $item->getPrice();
                $orderdetail['Total'] = $item->getRowTotalInclTax();
                $quantity = $item->getQtyOrdered();
                $orderdetail['Weight'] = $item->getWeight() * $quantity ;
                $stream->writeCsv($orderdetail);
            }

            $stream->unlock();
            $stream->close();

        }
    
}

您需要为此使用插件 -

注意 - 在发送邮件之前使用您的 csv 生成代码来附加文件

1. 在 etc 文件夹中创建 di.xml

   <?xml version="1.0"?>
    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"      xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
         <type name="Magento\Sales\Model\Order\Email\Sender\OrderSender">
                    <plugin name="AttachEmail" type="Vendor\Module_Name\Plugin\Model\Email\Sender\OrderSender"/>
                </type>
    <type name="Magento\Framework\Mail\TransportInterface">
            <plugin name="AttachEmailTransport" type="Vendor\Module_Name\Plugin\Model\Transport"/>
        </type>
    </config>
   

2. OrderSender 模型内部

用于识别订单电子邮件的重要文件

 <?php
    namespace Vendor\Module_Name\Plugin\Model\Email\Sender;
    use Magento\Framework\Registry;
    class OrderSender
    {
       
        public function __construct(
            Registry $registry
        ) {
            $this->registry = $registry;
        }
    
       
        public function beforeSend(
            $subject,
            $order
        ) {
            $this->registry->unregister('email_attachments_type');
            $this->registry->unregister('email_attachments_source');
            $this->registry->register('email_attachments_type', 'order');
            $this->registry->register('email_attachments_source', $order);
        }
    }
?>

1. 供应商\Module_Name\Plugin\Model\Transport

在这个文件中-

<?php

namespace Vendor\Module_Name\Plugin\Model;

use Magento\Framework\Mail\TransportInterface as Subject;
use Magento\Framework\Registry;
use Zend\Mime\Message;
use Zend\Mime\Part;

        if($source && $type == 'order'){
            
                   try {
                    //pass file name and it will get from media directory
