PHP laravel使用自定义邮件类实现发送邮件
作者：camellia
这篇文章主要为大家详细介绍了PHP laravel如何通过自定义邮件类实现发送邮件功能，文中的示例代码讲解详细，感兴趣的小伙伴可以尝试一下
当登录邮箱为腾讯企业邮箱的时候。
Phpmailer发送邮件就不好用了，具体哪里不好用，我没真没找到。
但是，邮件得发啊，怎么办呢？
我这里搞了一个自定义的发送邮件类，腾讯企业邮箱也可用。
但是，邮件发送失败，不会返回报错信息，这个可能是有点坑。
源码如下：
<?php
namespace App\Extend;
use Exception;
/**

class SmtpMail

}关于laravel5.8框架如何引入第三方类库，请参考下文补充内容 laravel8大同小异。
调用方法：
/**
* @name: 发送邮件方法
* @author: camellia
* @date: 2021-01-19
* @param: $email string 发送给谁
* @param: $mail_title string 邮件标题
* @param: $mail_body string 邮件内容
* @return: $result bool true/false
*/
public function send_mail($email, $mail_title, $mail_body)
{
$mail = new SmtpMail();
$mail->setServer(EMAIL_SERVER, SEND_EMAIL, EMAIL_SECERT, 465, true); //参数1（qq邮箱使用smtp.qq.com，qq企业邮箱使用smtp.exmail.qq.com），参数2（邮箱登陆账号），参数3（邮箱登陆密码，也有可能是独立密码，就是开启pop3/smtp时的授权码），参数4（默认25，腾云服务器屏蔽25端口，所以用的465），参数5（是否开启ssl，用465就得开启）//$mail->setServer("XXXXX", "joffe@XXXXX", "XXXXX", 465, true);
$mail->setFrom(SEND_EMAIL,"时间里的博客"); //发送者邮箱
$mail->setReceiver($email); //接收者邮箱
$mail->addAttachment(""); //Attachment 附件，不用可注释
$mail->setMail($mail_title, $mail_body); //标题和内容
$result = $mail->send(); //可以var_dump一下，发送成功会返回true，失败false
return $result;//*/
}代码亲测可用。
补充
laravel5.8引入第三方类库的方法详解
有需求需要使用PHPMailer发送邮件。
那么首先需要引入PHPMailer这个第三方的类库。我是这样做的：
1：在app目录下新建Extend目录。如下图所示：
将PHPMailer放入Extend目录下。如下图所示
2：修改项目根目录下的composer.json文件
"autoload": {
"psr-4": {
"App\\": "app/"
},
"classmap": [
"database/seeds",
"database/factories",
"app/Extend/PHPMailer/src"
]
},
添加你第三方类库的位置到autoload中
3：执行composer命令，在网站根目录下：
composer dump-autoload
4：调用：
（1）：使用命名空间
use PHPMailer\src\PHPMailer;
（2）：调用
//实例化PHPMailer核心类 $mail = new PHPMailer();
如果报错，就在实例化前边加一个转义符\
至此，laravel引入第三方类库成功。
