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;
/**
?*?一个简单的PHP?SMTP?发送邮件类

?
class?SmtpMail

调用方法：

????????$mail->setServer(EMAIL_SERVER,?SEND_EMAIL,?EMAIL_SECERT,?465,?true);?//参数1（qq邮箱使用smtp.qq.com，qq企业邮箱使用smtp.exmail.qq.com），参数2（邮箱登陆账号），参数3（邮箱登陆密码，也有可能是独立密码，就是开启pop3/smtp时的授权码），参数4（默认25，腾云服务器屏蔽25端口，所以用的465），参数5（是否开启ssl，用465就得开启）//$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。

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。

以上就是PHP laravel使用自定义邮件类实现发送邮件的详细内容，更多关于PHP laravel发送邮件的资料请关注其它相关文章！
