Codeigniter 3应用错误:无法通过电子邮件发送有效链接 [英] Codeigniter 3 applcation bug: unable to send valid link via email message

问题描述

我正在研究中的基本

我的错误在哪里?

解决方案

电子邮件未发送问题可能有多种原因:

1. Codeigniter 3电子邮件库配置不正确

测试:在php中使用内置的email()并测试其是否有效

2. php未正确配置为发送电子邮件
3. 服务器未配置为移交电子邮件
4. DNS具有外部MX记录，本地电子邮件未从服务器转发出去

测试:使用外部SMTP服务器(可以使用免费的gmail)并像这样配置ci3库

如果这不起作用，请使用

检查原因是什么

  if($ this->电子邮件-> send(FALSE)){回声$ this->电子邮件-> print_debugger();} 

5. 服务器无法访问远程端口，为此未打开防火墙

测试:禁用防火墙或selinux，然后再次测试

I am working on a basic blog application in Codeigniter 3.1.8 and Bootstrap 4.

I have added a registration and login system to this application. I am current working on a password reset system.

I was able to do these 2 things separately:

1. Send a password reset email containing dummy text.
2. Create a valid password reset link.

I was unable however, to send the email once the reset link was inserted into the email body.

Here is he controller:

class Newpassword extends CI_Controller {
    public function __construct()
    {
        parent::__construct();
    }

    private $sender_email = "[e-mail]";
    private $sender_name = "Razvan Zamfir";
    private $user_email = '';
    private $subject = 'Pasword reset link';
    private $reset_token = '';
    private $reset_url = '';
    private $reset_link = '';
    private $body = '';

    public function index() {
        // Display form
        $data = $this->Static_model->get_static_data();
        $data['pages'] = $this->Pages_model->get_pages();
        $data['tagline'] = 'Reset your password';
        $data['categories'] = $this->Categories_model->get_categories();

        // Form validation rules
        $this->form_validation->set_rules('email', 'Email', 'required|trim|valid_email');
        $this->form_validation->set_error_delimiters('<p class="error-message">', '</p>');

        if(!$this->form_validation->run()) {
            $this->load->view('partials/header', $data);
            $this->load->view('auth/passwordreset');
            $this->load->view('partials/footer');
        } else {
            if ($this->Usermodel->email_exists()) {

                  //Get user email
                  $this->user_email = $this->input->post('email');

                   //create token
                   $this->reset_token = md5(str_shuffle($this->user_email));

                    //create url
                       $this->reset_url = base_url('changepasword/') . $this->user_email . '/'. $this->reset_token;

                //create reset link
                $this->reset_link = '<a href="' . $this->reset_url . '">password reset link</a>';

                echo $this->reset_link;die();

                $this->body = "Here is your $this->reset_link. \n\nAfter clicking it you will be redirected to a page on the website where you will be able to set a new pasword.";

                // Send mail and rediect
                $this->sendResetMail();             
            } else {
                $this->session->set_flashdata('email_non_existent', "The email you provided does not exist in our database");
            }
           redirect('newpassword');
        }
    }

    public function sendResetMail() {
        // Loading the Email library
        $config['protocol'] = 'sendmail';
        $config['charset'] = 'utf-8';
        $config['mailtype'] = 'html';

        if(!$this->load->is_loaded('email')){
            $this->load->library('email', $config);
        } else {
          $this->email->initialize($config);
        }

        // Build the body and meta data of the email message
        $this->email->from($this->sender_email, $this->sender_name);
        $this->email->to($this->user_email);
        $this->email->subject($this->subject);
        
        $this->email->message($this->body);

        if($this->email->send()){
            $this->session->set_flashdata('reset_mail_confirm', "A pasword reset link was send to the email address $this->user_email");
        } else{
            $this->session->set_flashdata('reset_mail_fail', "Our atempt to send a pasword reset link to $this->user_email has failed");
        }
    }
}

I have inspected the link, it is valid and the value of the href attribute is as intended, but once I remove echo $this->reset_link;die() I see the attempt to send the email failing:

Where is my mistake?

解决方案

The email not sending issue can be from multiple reasons:

1. Codeigniter 3 email library is not configured correctly

test: use built in email() in php and test if that's working

2. php not configured correctly to send email
3. server is not configured for handing over emails
4. DNS has external mx records and local email is not forwarded out from the server

test: use external SMTP server (free gmail is fine) and configure like this the ci3 library https://forum.codeigniter.com/thread-75525-post-371979.html#pid371979

$config['protocol']  = 'smtp';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_user'] = 'your_email';
$config['smtp_pass'] = 'your_password';
$config['smtp_port'] = 465;
$config['charset']   = 'utf-8';
$config['mailtype']  = 'html';
$config['newline']   = "\r\n"; 

if this is not working, check what's the cause by using

if ($this->email->send(FALSE))
{
    echo $this->email->print_debugger();
}

5. server cannot access remote ports firewalls are not opened for this

test: disable firewall or selinux and test again
