How to change the password of email in thinkphp

1. Basic preparation

Before using the email password change function under the thinkphp framework, we need to complete the following preparations:

1. Install PHPMailer plug-in
   PHPMailer is a classic email sending plug-in that can send and receive emails, send attachments, etc. We need to install it into the thinkphp framework for use.

2. Configure email information in the config.php file
   We need to configure the corresponding email information in the config.php file, including SMTP server, email username, password, etc.

3. Write the email password change page
   We need to display the email password change related pages and implement the email password change through the call of the controller.

2. Write the email password change controller

1. Create the controller
   In the thinkphp framework, we You need to create a controller file first to control actions related to changing the email password.

2. Set the properties of the controller
   We need to set the properties of the controller, including the namespace of the current controller, its module, layout file, etc.

3. Writing a password modification method
   We need to write a method called modifyPassword, obtain the user's current password and new password through the parameters in the method, and then send an email through the PHPMailer plug-in change Password.

The sample code is as follows:

<?php
namespace app\index\controller;
use think\Controller;
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

class Email extends Controller{
    protected $module=&#39;index&#39;;
    protected $layout=&#39;public/layout&#39;;
    protected $namespace=&#39;app\index\controller&#39;;
    
    public function modifyPassword($email,$oldPassword,$newPassword){
        //新建PHPMailer对象
        $mail=new PHPMailer(true);
        
        //配置SMTP服务器信息
        $mail->isSMTP();
        $mail->SMTPAuth=true;
        $mail->SMTPSecure=&#39;ssl&#39;;
        $$mail->Host=&#39;smtp.gmail.com&#39;;
        $mail->Port=465;
        $mail->Username=&#39;xxxx@gmail.com&#39;;
        $mail->Password=&#39;xxxx&#39;;
        
        //配置邮件内容
        $mail->setFrom(&#39;xxxx@gmail.com&#39;,&#39;管理员&#39;);
        $mail->addAddress($email);
        $mail->Subject=&#39;修改密码&#39;;
        $mail->Body="您的当前密码是{$oldPassword}，新密码是{$newPassword}"；
        
        //发送邮件
        if(!$mail->send()){
            echo &#39;邮件发送失败：&#39; . $mail->ErrorInfo;
        }else{
            echo &#39;邮件发送成功&#39;;
        }
    }
}

3. Complete the email password change function

After completing the writing of the above controller , we need to create corresponding routes to connect the relevant pages for changing passwords via email with the controller.

After accessing the email password change page, you need to enter the current password and new password, and then transfer the data to the controller and send the email to implement the email password change function.

Finally, it should be noted that the email password changing function is very sensitive and critical, so the confidentiality of key codes needs to be strengthened during the development process to ensure the security of the program.
