邮件发送

1.安装PHPMailer扩展。

composer require phpmailer/phpmailer

2.配置文件设置邮件信息

'email_config'=>[
        'mail_host' =>  'smtp.163.com',//邮件发送域名
        'mail_port' =>  '994',//邮件发送端口，994/465
        'mail_user' =>  'test@163.com',//邮箱账号
        'mail_password' =>  'XXXXXXXXX',//邮件发送授权码
        'mail_form' =>  'test@163.com',//显示的发件人邮箱（邮箱账号）
        'mail_secure' =>  'ssl'//ssl网络模式
    ],

　　

3.封装邮件发送类

<?php
/**
 * 邮件助手类
 */

namespace app\service;

use PHPMailer\PHPMailer\PHPMailer;
use think\Config;
use think\Exception;
use think\Url;


// https://packagist.org/packages/phpmailer/phpmailer
class Mail
{
    private $Form = '';
    private $Host='';
    private $Username='';
    private $Password = '';
    private $Secure = '';
    private $Port = '';

    public function __construct()
    {
        $config = Config::get('email_config');
        $this->Form = $config['mail_form'];
        $this->Host = $config['mail_host'];
        $this->Username = $config['mail_user'];
        $this->Password = $config['mail_password'];
        $this->Secure = $config['mail_secure'];
        $this->Port = $config['mail_port'];
    }

    /**
     * @param $toEmail 接受邮件用户
     * @param $Subject 邮件标题
     * @param null $content 邮件内容
     * @param null $html 邮件模板
     * @param null $attachment 邮件附件
     * @throws \PHPMailer\PHPMailer\Exception
     *
     */
    public function sendEmail($toEmail,$Subject,$content=null,$html=null,$attachment=null){
        $email = new PHPMailer();

        try {
            // 设置邮件格式
            $email->isSMTP();
            // 设置有见程序使用SMTP 格式
            $email->Host = $this->Host;
            // 设置有见内容的编码
            $email->CharSet = 'UTF-8';
            // 启用SMTP验证
            $email->SMTPAuth = true;
            // SMTP username
            $email->Username = $this->Username;
            // SMTP password
            $email->Password = $this->Password;
            // 启用TLS加密，`ssl`也被接受
            $email->SMTPSecure = $this->Secure;
            // 连接的TCP端口
            $email->Port = $this->Port;
            //设置发件人
            $email->setFrom($this->Form, '讯飞产业加速中心');

            // 设置收件人
            $email->addAddress($toEmail);
            // 设置如果收件人回复邮件  直接显示我的邮件
            $email->addReplyTo($this->Form);
            if ($attachment){
                $email->AddAttachment('./PDF/'.basename($attachment),basename($attachment));
            }

            $email->isHTML();
            $email->Subject = $Subject;
            if ($html){
                $content = file_get_contents($html);
            }

            $email->Body = $content;
            if ($email->send()){
                return 'success';
            }else{
                echo "Mailer Error: ".$email->ErrorInfo;// 输出错误信息
            }
        }catch (Exception $e){
            echo "Mail Error:" . $e->ErrorInfo;
        }

    }

    



}

4.控制器调用

$sendEmail = new Mail();
            $sendEmail->sendEmail($admin_id['email'],'邮件标题','邮件内容');
