Performance testing and tuning methods for PHP email docking class

// 假设使用PHPMailer作为邮件对接类 require 'vendor/phpmailer/phpmailer/src/PHPMailer.php'; //...初始化邮件对象 // 发送邮件 function sendEmail($mailer, $to, $subject, $body) { $mailer->addAddress($to); $mailer->Subject = $subject; $mailer->Body = $body; return $mailer->send(); } // 压力测试函数 function stressTest($mailer, $to, $subject, $body, $totalRequests) { $successCount = 0; $failureCount = 0; for ($i = 0; $i < $totalRequests; $i++) { echo "Sending email: ", $i+1, " of ", $totalRequests, " "; if (sendEmail($mailer, $to, $subject, $body)) { $successCount++; } else { $failureCount++; } // 休眠一段时间，模拟真实场景下的请求间隔 usleep(mt_rand(1000, 5000)); } echo "Successful requests: ", $successCount, " "; echo "Failed requests: ", $failureCount, " "; } // 压力测试参数 $totalRequests = 100; // 总请求数 $to = "recipient@example.com"; // 收件人邮箱 $subject = "Test Email"; // 邮件主题 $body = "This is a test email."; // 邮件内容 // 创建邮件对象 $mailer = new PHPMailerPHPMailerPHPMailer(); // 进行压力测试 stressTest($mailer, $to, $subject, $body, $totalRequests);
