PHP Mailer返回PHP致命错误：未捕获PHPMailerPHPMailerException：SMTP错误：无法进行身份验证

2022-03-31 00:00:00 email php javascript html phpmailer

我看到了很多类似的问题，像我的，但从来没有一个，这对我有帮助。我正在尝试https://github.com/PHPMailer/PHPMailer中的PHPMailer。我正在用XAMPP服务器测试它，一切都运行得很好。但当我将整个phpMailer上传到我的页面时，出现了一些问题。在我的日志文件中，我仍然收到以下错误：

PHP致命错误：未捕获PHPMailerPHPMailerException：SMTP错误：无法进行身份验证。在/web/test/vendor/phpmailer/phpmailer/src/PHPMailer.php:2089中堆栈跟踪： #0 web/test/vendor/phpmailer/phpmailer/src/PHPMailer.php(1900)：PHPMailerPHPMailerPHPMailer->；smtpConnect() #1 web/test/vendor/phpmailer/phpmailer/src/PHPMailer.php(1614)：PHPMailerPHPMailerPHPMailer->；smtpSend() #2 web/test/vendor/phpmailer/phpmailer/src/PHPMailer.php(1447)：PHPMailerPHPMailer->；postSend() #3web/test/idk.php(31)：PHPMailerPHPMailerPHPMailer->；Send() #4{Main} 在2089行的web/test/vendor/phpmailer/phpmailer/src/PHPMailer.php中抛出`

有人知道如何解决这个问题吗？我非常确定我的登录凭据是正确的。奇怪的是，它在Xampp上运行良好，但在我的页面上不起作用。我使用的是最新的PHPMailer，我没有编辑任何东西，所以你可以在PHPMailer GitHub上看到代码。如果有人需要更多的信息，尽管告诉我。非常感谢！

编辑：以下是我的idk.php文件(代码片段运行不是很好，但我认为您可以阅读它)：

<?php 
declare( strict_types = 1 );

// Check if the form is submitted
if ( isset( $_POST['submit'] ) ) {
    // retrieve the form data by using the element's name attributes value as key
    
    $subject = $_REQUEST['subject'];
    $body = $_REQUEST['body'];
    $sender = $_REQUEST['sender'];

    require __DIR__ . '/vendor/autoload.php';

    $mailer = new PHPMailerPHPMailerPHPMailer( true );
    //$mailer->SMTPDebug = PHPMailerPHPMailerSMTP::DEBUG_SERVER tento řádek povoluje client -> server a server -> client zprávy

    $mailer->isSMTP();
    $mailer->Host = 'smtp.gmail.com';
    $mailer->SMTPAuth = true;
    $mailer->Username = 'my@mail.com';
    $mailer->Password = 'myPassword';
    $mailer->SMTPSecure = PHPMailerPHPMailerPHPMailer::ENCRYPTION_STARTTLS;
    $mailer->Port = 587;
    $mailer->setFrom( 'my@mail.com' );
    $mailer->addReplyTo( 'my@mail.com' );
    $mailer->addAddress( $sender );
    $mailer->isHTML( true );
    $mailer->Subject = $subject;
    $mailer->Body = $body;
    $mailer->send();
}
?>

也许我应该说我在我的虚拟主机上使用的是.htaccess文件。我不确定，但也许这就是我收到这些错误的原因。当我尝试访问idk.php文件时，收到http错误500。我做了一些调查，这个500错误和htaccess文件之间有一些联系。

编辑：我关闭了安全性较低的应用程序，但它仍然不起作用。我将端口更改为465，现在此文件中2076行的错误：https://github.com/PHPMailer/PHPMailer/blob/master/src/PHPMailer.php

解决方案

这是Gmail问题，您需要关闭安全程度较低的应用程序访问

详细信息： https://support.google.com/accounts/answer/6010255?hl=en#zippy=%2Cif-less-secure-app-access-is-on-for-your-account%2Cif-less-secure-app-access-is-off-for-your-account

关闭安全性较低的应用访问(&Q；)

示例(PHPMailer v6.2.0)

<?php

/**
 * This example shows settings to use when sending via Google's Gmail servers.
 * This uses traditional id & password authentication - look at the gmail_xoauth.phps
 * example to see how to use XOAUTH2.
 * The IMAP section shows how to save this message to the 'Sent Mail' folder using IMAP commands.

//Import PHPMailer classes into the global namespace
use PHPMailerPHPMailerPHPMailer;

require 'vendor/autoload.php';

//Create a new PHPMailer instance
$mail = new PHPMailer();

//Tell PHPMailer to use SMTP
$mail->isSMTP();

//Enable SMTP debugging

//Set the hostname of the mail server
$mail->Host = 'smtp.gmail.com';
// use
// $mail->Host = gethostbyname('smtp.gmail.com');
// if your network does not support SMTP over IPv6

//Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
$mail->Port = 587;

//Set the encryption mechanism to use - STARTTLS or SMTPS
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS;

//Whether to use SMTP authentication
$mail->SMTPAuth = true;

//Username to use for SMTP authentication - use full email address for gmail
$mail->Username = 'CHANGEME';

//Password to use for SMTP authentication
$mail->Password = 'CHANGEME';

//Set who the message is to be sent from
$mail->setFrom('from@example.com', 'First Last');

//Set an alternative reply-to address

//Set who the message is to be sent to

//Set the subject line
$mail->Subject = 'PHPMailer GMail SMTP test';

$mail->msgHTML('This is a plain-text message body');


//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';

//Attach an image file

//send the message, check for errors
if (!$mail->send()) {
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message sent!';
    //Section 2: IMAP
    //Uncomment these to save your message in the 'Sent Mail' folder.
