OAuth 2.0 配置设置-PHP中文网问答

我使用 phpmailer 通过 smtp.google.com 服务器发送邮件，但现在它无法正常工作，因为他们说使用 OAuth2.0 配置。

我参考了一些示例并使用使用 PhpMailer 和 Gmail XOAUTH2 发送电子邮件创建了一个示例页面来测试它，但它不起作用。谁能指出代码中出了什么问题吗？

这是我的 html 页面

<?php
namespace Phppot;

require_once ("lib/MailService.php");
$mailService = new MailService();
if (! empty($_POST['send'])) {
    $response = $mailService->sendContactMail($_POST);
}
?>
<html>
<head>
<title>Contact Us Form</title>
<link rel="stylesheet" type="text/css" href="assets/css/style.css" />
</head>
<body>
    <div class="form-container">
        <form name="frmContact" id="" frmContact"" method="post"
            action="" enctype="multipart/form-data"
            onsubmit="return validateContactForm()">

            <div class="input-row">
                <label style="padding-top: 20px;">Name</label> <span
                    id="userName-info" class="info"></span><br /> <input
                    type="text" class="input-field" name="userName"
                    id="userName" />

            <div class="input-row">

                <input type="submit" name="send" class="btn-submit"
                    value="Send" />

                <div id="statusMessage">
                        <?php
                        if (! empty($response)) {
                            ?>

                        }
                        ?>

        </form>
    </div>

您遇到命名空间问题。你正在这样做：

namespace Phppot;

use Phppot\Config;
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

然后使用这个：

$mail->SMTPDebug = SMTP::DEBUG_OFF;

因为您尚未将 PHPMailer 包中的 SMTP 类名导入到您的命名空间中，所以它将查找名为 Phppot\SMTP 的类，该类不存在，因此会出现错误消息。您可以通过添加以下内容来解决此问题：

use PHPMailer\PHPMailer\SMTP;

这将使它使用 PHPMailer 中正确的 SMTP 类。

请注意，这里可能存在另一个问题。您已经 use Phppot\Config;，但您已经在 Phppot 命名空间中，因此将查找名为 Phppot\Phppot\Config，可能不存在。如果该类已位于您声明的命名空间中，则不需要为其使用 use 语句。
