Laravel邮件处理全攻略：接收 + 发送

在现代Web开发中，邮件功能是企业应用不可或缺的一部分。Laravel作为最流行的PHP框架，提供了优雅的邮件发送解决方案，但接收邮件同样重要。今天我们就来深度探讨如何在Laravel中实现完整的邮件处理方案。

一、为什么需要完整的邮件解决方案？

在真实业务场景中，我们经常需要：

  • 发送交易通知、营销邮件
  • 接收用户反馈、客服咨询
  • 处理自动回复和邮件跟踪
  • 构建完整的邮件工作流

单纯发送邮件已经无法满足复杂业务需求，接收和处理邮件同样重要。

二、Laravel原生邮件发送：简洁而强大

2.1 基础配置

Laravel的邮件配置非常直观，在 .env 文件中：

MAIL_MAILER=smtp
MAIL_HOST=smtp.qq.com
MAIL_PORT=587
MAIL_USERNAME=your-email@qq.com
MAIL_PASSWORD=your-authorization-code
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=your-email@qq.com
MAIL_FROM_NAME="你的应用名称"

2.2 创建可邮件类

php artisan make:mail OrderShipped

<?php

namespace App\Mail;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;

class OrderShipped extends Mailable
{
    use Queueable, SerializesModels;

    public $order;

    public function __construct($order)
    {
        $this->order = $order;
    }

    public function build()
    {
        return $this->from('noreply@example.com', '应用名称')
                   ->subject('订单发货通知')
                   ->view('emails.orders.shipped')
                   ->attach(storage_path('app/invoices/' . $this->order->invoice));
    }
}

2.3 发送邮件

use App\Mail\OrderShipped;
use Illuminate\Support\Facades\Mail;

// 简单发送
Mail::to($request->user())
    ->send(new OrderShipped($order));

// 队列发送（推荐）
Mail::to($request->user())
    ->queue(new OrderShipped($order));

// 批量发送
foreach ($users as $user) {
    Mail::to($user->email)->queue(new Notification($content));
}

三、webklex/laravel-imap：专业的邮件接收方案

3.1 安装和配置

composer require webklex/laravel-imap

发布配置文件：

php artisan vendor:publish --provider="Webklex\IMAP\Providers\LaravelServiceProvider"

配置多个邮箱账户：

// config/imap.php
return [
    'accounts' => [
        'qq' => [
            'host' => 'imap.qq.com',
            'port' => 993,
            'encryption' => 'ssl',
            'validate_cert' => true,
            'username' => 'your-qq@qq.com',
            'password' => 'your-authorization-code',
            'protocol' => 'imap'
        ],
        'gmail' => [
            'host' => 'imap.gmail.com',
            'port' => 993,
            'encryption' => 'ssl',
            'validate_cert' => true,
            'username' => 'your@gmail.com',
            'password' => 'your-app-password',
            'protocol' => 'imap'
        ]
    ]
];

3.2 基本邮件接收

use Webklex\IMAP\Facades\Client;

public function fetchEmails()
{
    $client = Client::account('qq');
    $client->connect();
    
    // 获取收件箱
    $folder = $client->getFolder('INBOX');
    
    // 获取未读邮件
    $messages = $folder->query()
        ->unseen()
        ->limit(10)
        ->get();
    
    $emails = [];
    foreach ($messages as $message) {
        $emails[] = [
            'subject' => $message->getSubject(),
            'from' => $message->getFrom()[0]->mail,
            'date' => $message->getDate(),
            'body' => $message->getHTMLBody() ?: $message->getTextBody(),
            'attachments' => $message->getAttachments()
        ];
        
        // 标记为已读
        $message->setFlag('SEEN');
    }
    
    return $emails;
}

3.3 高级邮件处理

public function processCustomerEmails()
{
    $client = Client::account('qq');
    $client->connect();
    
    $folder = $client->getFolder('INBOX');
    
    // 复杂查询：今天收到的特定主题邮件
    $messages = $folder->query()
        ->since(now()->subDays(1))
        ->whereSubject('客户咨询')
        ->get();
    
    foreach ($messages as $message) {
        // 解析邮件内容
        $emailData = $this->parseEmail($message);
        
        // 创建工单
        $ticket = Ticket::create([
            'subject' => $emailData['subject'],
            'content' => $emailData['body'],
            'customer_email' => $emailData['from'],
            'priority' => $this->detectPriority($emailData)
        ]);
        
        // 处理附件
        if ($message->hasAttachments()) {
            $this->saveAttachments($message, $ticket);
        }
        
        // 发送自动回复
        Mail::to($emailData['from'])
            ->queue(new AutoReply($ticket));
        
        // 移动邮件到已处理文件夹
        $message->moveToFolder('Processed');
    }
}

四、实战案例：构建客服邮件系统

4.1 数据库设计

// 客服工单表
Schema::create('support_tickets', function (Blueprint $table) {
    $table->id();
    $table->string('email');
    $table->string('subject');
    $table->text('content');
    $table->enum('status', ['open', 'in_progress', 'resolved']);
    $table->string('message_id')->unique();
    $table->timestamps();
});

// 邮件对话表
Schema::create('ticket_conversations', function (Blueprint $table) {
    $table->id();
    $table->foreignId('ticket_id')->constrained();
    $table->enum('type', ['incoming', 'outgoing']);
    $table->text('content');
    $table->json('attachments')->nullable();
    $table->timestamps();
});

4.2 自动邮件处理器

<?php

namespace App\Services;

use Webklex\IMAP\Facades\Client;
use App\Models\SupportTicket;
use App\Models\TicketConversation;
use Illuminate\Support\Facades\Mail;
use App\Mail\SupportAutoReply;

class EmailProcessorService
{
    public function processIncomingEmails()
    {
        $client = Client::account('qq');
        $client->connect();
        
        $folder = $client->getFolder('INBOX');
        $messages = $folder->query()->unseen()->get();
        
        foreach ($messages as $message) {
            try {
                $this->processSingleEmail($message);
                $message->setFlag('SEEN');
            } catch (\Exception $e) {
                \Log::error('处理邮件失败: ' . $e->getMessage());
            }
        }
    }
    
    private function processSingleEmail($message)
    {
        $from = $message->getFrom()[0]->mail;
        $subject = $message->getSubject();
        $body = $message->getHTMLBody() ?: $message->getTextBody();
        
        // 查找或创建工单
        $ticket = SupportTicket::firstOrCreate(
            ['message_id' => $message->getMessageId()],
            [
                'email' => $from,
                'subject' => $subject,
                'content' => $body,
                'status' => 'open'
            ]
        );
        
        // 保存对话记录
        TicketConversation::create([
            'ticket_id' => $ticket->id,
            'type' => 'incoming',
            'content' => $body,
            'attachments' => $this->saveEmailAttachments($message, $ticket)
        ]);
        
        // 发送自动回复
        if ($ticket->wasRecentlyCreated) {
            Mail::to($from)->queue(new SupportAutoReply($ticket));
        }
        
        // 通知客服团队
        $this->notifySupportTeam($ticket);
    }
}

4.3 定时任务配置

// app/Console/Kernel.php
protected function schedule(Schedule $schedule)
{
    $schedule->call(function () {
        app(EmailProcessorService::class)->processIncomingEmails();
    })->everyFiveMinutes();
}

在宝塔面板中配置计划任务：

cd /www/wwwroot/your-project && php artisan schedule:run

五、性能优化和最佳实践

5.1 队列处理

// 将邮件处理放入队列
class ProcessEmailJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    public $messageId;

    public function __construct($messageId)
    {
        $this->messageId = $messageId;
    }

    public function handle()
    {
        // 处理邮件逻辑
    }
}

// 在控制器中
ProcessEmailJob::dispatch($message->getMessageId());

5.2 错误处理和重试机制

public function handle()
{
    try {
        $this->processEmail();
    } catch (\Webklex\IMAP\Exceptions\ConnectionFailedException $e) {
        // IMAP连接失败，记录日志并重试
        \Log::error('IMAP连接失败: ' . $e->getMessage());
        $this->release(60); // 60秒后重试
    } catch (\Exception $e) {
        \Log::error('处理邮件失败: ' . $e->getMessage());
    }
}

5.3 内存管理

public function processLargeMailbox()
{
    $client = Client::account('qq');
    $client->connect();
    
    $folder = $client->getFolder('INBOX');
    $messages = $folder->query()->limit(100)->paginate();
    
    foreach ($messages as $message) {
        $this->processMessage($message);
        
        // 及时释放内存
        unset($message);
        gc_collect_cycles();
    }
}

六、安全考虑

6.1 输入验证和过滤

public function processEmailContent($rawContent)
{
    // 清理HTML内容，防止XSS攻击
    $cleanContent = Purifier::clean($rawContent);
    
    // 验证发件人邮箱格式
    if (!filter_var($fromEmail, FILTER_VALIDATE_EMAIL)) {
        throw new InvalidEmailException('无效的邮箱地址');
    }
    
    return $cleanContent;
}

6.2 附件安全处理

private function saveEmailAttachments($message, $ticket)
{
    $savedAttachments = [];
    
    foreach ($message->getAttachments() as $attachment) {
        $filename = $attachment->getName();
        $extension = strtolower(pathinfo($filename, PATHINFO_EXTENSION));
        
        // 检查文件类型
        $allowedExtensions = ['pdf', 'doc', 'docx', 'jpg', 'png', 'txt'];
        if (!in_array($extension, $allowedExtensions)) {
            continue; // 跳过不允许的文件类型
        }
        
        // 生成安全文件名
        $safeFilename = uniqid() . '_' . Str::slug($filename);
        $filepath = "attachments/ticket_{$ticket->id}/{$safeFilename}";
        
        Storage::disk('local')->put($filepath, $attachment->getContent());
        
        $savedAttachments[] = [
            'original_name' => $filename,
            'saved_path' => $filepath,
            'size' => $attachment->getSize()
        ];
    }
    
    return $savedAttachments;
}

七、监控和日志

7.1 完整的日志记录

class EmailLogger
{
    public function logEmailActivity($action, $email, $details = [])
    {
        \Log::channel('emails')->info($action, [
            'email' => $email,
            'timestamp' => now(),
            'details' => $details,
            'ip' => request()->ip(),
            'user_agent' => request()->userAgent()
        ]);
    }
}

7.2 性能监控

public function processWithMonitoring()
{
    $startTime = microtime(true);
    $memoryStart = memory_get_usage();
    
    $this->processIncomingEmails();
    
    $executionTime = microtime(true) - $startTime;
    $memoryUsed = memory_get_usage() - $memoryStart;
    
    \Log::channel('performance')->info('邮件处理性能统计', [
        'execution_time' => $executionTime,
        'memory_used' => $memoryUsed,
        'emails_processed' => $this->emailsProcessed,
        'timestamp' => now()
    ]);
}

八、总结
