使用 PHPMailer 通过 PHP 发送电子邮件时出现问题：出现“无法发送邮件”错误

Question

我在尝试使用 PHP 的 PHPMailer 库发送电子邮件时遇到问题。我收到一条错误消息，显示“无法发送邮件”。我尝试了不同的方式来发送邮件，即使我得到了 ChatGpt 的帮助，但我不能。我已按照文档进行操作，我的代码如下所示：

<form action="mail.php" method="post">
    <input type="text" name="name">
    <input type="email" name="email" id="">
    <input type="submit" value="submit">
</form>

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

require __DIR__ . '/PHPMailer-master/PHPMailer.php';
require __DIR__ . '/PHPMailer-master/Exception.php';
require __DIR__ . '/PHPMailer-master/SMTP.php';

if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $name = $_POST['name'];
    $email = $_POST['email'];

    $mail = new PHPMailer(true);

    try {
        // SMTP configuration
        $mail->isSMTP();
        $mail->Host = 'smtp.gmail.com';
        $mail->SMTPAuth = true;
        $mail->Username = '[email protected]';
        $mail->Password = 'mypassword'; // Replace with your Gmail password
        $mail->SMTPSecure = 'tls';
        $mail->Port = 587;

        // Sender and recipient details
        $mail->setFrom('[email protected]', 'Ahmed Maajid');
        $mail->addAddress('[email protected]'); // Set your Gmail address as both sender and recipient

        // Email content
        $mail->isHTML(false);
        $mail->Subject = 'New submission from your website';
        $mail->Body = 'Name: ' . $name . "\n\n" . 'Email: ' . $email;

        $mail->send();
        echo 'Email sent successfully!';
    } catch (Exception $e) {
        echo 'Oops! There was a problem: ' . $mail->ErrorInfo;
    }
}
?>

Composer 是启动和运行 PHPMailer 的最简单方法。只需打开终端并输入：

composer require phpmailer/phpmailer

。这是发送电子邮件的代码片段：

require("./vendor/phpmailer/phpmailer/src/PHPMailer.php");
require("./vendor/phpmailer/phpmailer/src/SMTP.php");


// make all the setup to send email
$mail = new PHPMailer\PHPMailer\PHPMailer();
$mail->IsSmtp();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'tls';
$mail->SMTPOptions = array(
    'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
    )
);
$mail->Host = "smtp.gmail.com";
$mail->Port = 587; 
$mail->IsHTML(true);
$mail->Username = "[email protected]";
$mail->Password = "your_password";
$mail->setFrom("[email protected]");
// make email subject & body
$subject = "testing subject";
$messageBody = "testing message";
$mail->Subject = $subject;
$mail->Body = $messageBody;
// send to
$sendTo = "[email protected]";
$mail->AddAddress($sendTo);
// send request
if($mail->Send()) {
    echo 'Email has been sent!';
} else {
    echo $mail->ErrorInfo;
}
