Question

以下是我的php代码。我第一次使用gcp应用引擎，它引发错误PHP致命错误：require（）：无法打开所需的“ vendor / phpmailer / phpmailer / src / Exception.php”。我已经在提到的目录中拥有此文件，然后它也显示此错误。是关于新的phpmailer格式还是其他？请帮忙。

在StackOverflow上搜索已经存在的案例时，我遇到了这一案例： PHP namespaces and "use"

此外，如果我是对的，则需要在使用“ use”语句之前导入文件，如下所示：

<?php
  require 'vendor/phpmailer/phpmailer/src/Exception.php';
  require 'vendor/phpmailer/phpmailer/src/PHPMailer.php';
  require 'vendor/phpmailer/phpmailer/src/SMTP.php';
  use PHPMailer\PHPMailer\PHPMailer;
  use PHPMailer\PHPMailer\Exception;
  use PHPMailer\PHPMailer\SMTP;

如果您通过composer安装了PHPMailer，我认为您不需要此，所以我已从代码中删除了这部分。

require 'vendor/phpmailer/phpmailer/src/Exception.php';
require 'vendor/phpmailer/phpmailer/src/PHPMailer.php';
require 'vendor/phpmailer/phpmailer/src/SMTP.php';

尝试以下代码。我已经重新格式化了您的代码。

<?php
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
use PHPMailer\PHPMailer\SMTP;

// Include Composer autoload.php file
require 'vendor/autoload.php';

// Create object of PHPMailer class
$mail = new PHPMailer(true);

$output = '';

if (isset($_POST['submit'])) {
    $name = $_POST['contactName'];
    $email = $_POST['contactEmail'];
    $subject = $_POST['contactSubject'];
    $message = $_POST['contactMessage'];

    try {
        $mail->isSMTP();
        $mail->Host = 'smtp.gmail.com';
        $mail->SMTPAuth = true;
        // Gmail ID which you want to use as SMTP server
        $mail->Username = 'rajeshsingh80906@gmail.com';
        // Gmail Password
        $mail->Password = 'secret';
        $mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;
        $mail->Port = 587;

        // Email ID from which you want to send the email
        $mail->setFrom('rajeshsingh80906@gmail.com');
        // Recipient Email ID where you want to receive emails
        $mail->addAddress('ranarajesh495@gmail.com');
        // $mail->addAttachment(''); 
        $mail->isHTML(true);
        $mail->Subject = 'Form Submission';
        $mail->Body = "<h3>Name : $name <br>Email : $email <br>Message : $message</h3>";

        $mail->send();
        $output = '<div class="alert alert-success"><h5>Thankyou! for contacting us, We\'ll get back to you soon!</h5></div>';
    }
    catch (Exception $e) {
        $output = '<div class="alert alert-danger"><h5>' . $e->getMessage() . '</h5></div>';
    }
}
?>
