本文介绍了如何在 CodeIgniter 框架中使用电子邮件打印调试器,以便程序员在调试电子邮件相关问题时更加高效。
application/libraries
目录下。Email_debugger.php
application/config/email.php
配置文件中添加以下配置。$config['smtp_debug'] = TRUE;
$this->load->library('email_debugger');
在使用 CodeIgniter 框架发送电子邮件的时候,如果需要打印调试信息,可以使用 $this->email->print_debugger()
方法,该方法会输出当前电子邮件发送的完整调试信息。而使用本调试器,将会在控制台中以更加友好的格式展示调试信息,同时也能够将调试信息记录到文本文件中,方便后续检查。
要使用本调试器,只需要将调用 $this->email->print_debugger()
方法的地方改为 $this->email_debugger->print_debugger()
即可。
<?php
class Email_debugger
{
private $CI;
private $enabled = true;
private $debug = array();
private $log_path = '';
public function __construct()
{
$this->CI =& get_instance();
$this->CI->load->library('email');
$this->log_path = $this->CI->config->item('email_log_path');
if(empty($this->log_path))
$this->log_path = APPPATH . 'logs/email_log.txt';
$this->enabled = $this->CI->config->item('smtp_debug');
$this->debug['path'] = $this->log_path;
}
public function print_debugger()
{
$this->CI->email->print_debugger();
if($this->enabled)
{
$debug = $this->CI->email->get_debugger();
$this->debug['debugger'] = $debug;
$this->debug_to_log();
echo "<pre>".print_r($debug, true)."</pre>";
}
}
private function debug_to_log()
{
$log_data = date('Y-m-d H:i:s') . " - Email Debug:\n";
$log_data .= $this->debug['debugger'] . "\n\n";
if(!file_exists($this->log_path))
$this->write_file('', $this->log_path);
$temp_file = $this->log_path.'_temp';
$this->write_file($log_data, $temp_file, 'a');
@rename($temp_file, $this->log_path);
}
private function write_file($data, $filename, $mode = 'wb')
{
if ( ! $fp = @fopen($filename, $mode))
{
return false;
}
flock($fp, LOCK_EX);
fwrite($fp, $data);
flock($fp, LOCK_UN);
fclose($fp);
return true;
}
}
$this->load->library('email_debugger');
$this->email->initialize([
'protocol' => 'smtp',
'smtp_host' => 'smtp.qq.com',
'smtp_user' => 'example@qq.com',
'smtp_pass' => 'password',
'smtp_port' => '465',
'smtp_crypto' => 'ssl',
'mailtype' => 'html',
'charset' => 'utf-8'
]);
$this->email->to('foo@example.com');
$this->email->from('bar@example.com');
$this->email->subject('Testing email sending');
$this->email->message('This is a test email');
$this->email->send();
// 使用调试器打印调试信息,而不是原本的 $this->email->print_debugger() 方法
$this->email_debugger->print_debugger();
本调试工具将会以更加友好的方式展示电子邮件发送调试信息,对于需要调试电子邮件发送问题的程序员来说,是一个非常不错的工具。
