php - 发送qq邮箱信息
2024-04-14 00:18:45
有时候我们在网站上看见别的网站通过QQ邮箱完成实名认证是如何实现的呢？查了很多资料，终于找到啦。
互不多说，直接上代码。 可以直接用哦，记得复制和粘贴。
运行index.php
<?php
require('PHPMailer.php');
require('SMTP.php');//use PHPMailer\PHPMailer\PHPMailer;// 实例化PHPMailer核心类
$mail = new PHPMailer();// 是否启用smtp的debug进行调试 开发环境建议开启 生产环境注释掉即可 默认关闭debug调试模式
$mail->SMTPDebug = 1;// 使用smtp鉴权方式发送邮件
$mail->isSMTP();// smtp需要鉴权 这个必须是true
$mail->SMTPAuth = true;// 链接qq域名邮箱的服务器地址
$mail->Host = 'smtp.qq.com';// 设置使用ssl加密方式登录鉴权
$mail->SMTPSecure = 'ssl';// 设置ssl连接smtp服务器的远程服务器端口号
$mail->Port = 465;// 设置发送的邮件的编码
$mail->CharSet = 'UTF-8';// 设置发件人昵称 显示在收件人邮件的发件人邮箱地址前的发件人姓名
$mail->FromName = '科沛科技';// smtp登录的账号 QQ邮箱即可
$mail->Username = '';// smtp登录的密码 使用生成的授权码
$mail->Password = '';// 设置发件人邮箱地址 同登录账号
$mail->From = '';// 邮件正文是否为html编码 注意此处是一个方法
$mail->isHTML(true);// 设置收件人邮箱地址
$mail->addAddress('');// 添加多个收件人 则多次调用方法即可
//$mail->addAddress('87654321@163.com');// 添加该邮件的主题
$mail->Subject = '测试邮件主题';// 添加邮件正文
$mail->Body = '';// 为该邮件添加附件
//$mail->addAttachment('./example.pdf');// 发送邮件 返回状态
$status = $mail->send();
