SMTP错误：无法进行身份验证。无法发送消息。邮件程序错误：SMTP错误：无法进行身份验证

Question

当我尝试使用PHP SMTP电子邮件服务器发送电子邮件时，发生了以下错误。

SMTP Error: Could not authenticate. Message could not be sent.

邮件程序错误：SMTP错误：无法进行身份验证。

下面是我使用的代码。

function supervisorMail(){

global $error;
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = 'ssl';
$mail->Host = 'smtp.gmail.com';
$mail->Port = 465;
$mail->Username = "***@gmail.com";
$mail->Password = "****";
$mail->SetFrom("***@gmail.com", "Employee Leave Management System");

$userID=$_SESSION['userID'];

$select_query = mysql_query("SELECT * FROM employee WHERE emp_id = '$userID'");
$select_sql = mysql_fetch_array($select_query);
$name=$select_sql['manager_name'];
var_dump($name);

$select_query1 = mysql_query("SELECT email FROM employee WHERE emp_id='$name'");
$select_sql1 = mysql_fetch_array($select_query1);
$email=$select_sql1['email'];
    var_dump($email);

$mail->Subject = "subject ";
$mail->Body = "something.";
$mail_to = $email;
$mail->AddAddress($mail_to);

if(!$mail->Send())
{
    echo "Message could not be sent. <p>";
    echo "Mailer Error: " . $mail->ErrorInfo;
    exit;
}

echo "Message has been sent";

}

如何修复此错误。

Answer 1

正如评论中提到的，您需要输入有效的gmail id和密码。

请参考下面的演示代码。

<?php
require 'PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->SMTPDebug = 2;    // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;   // Enable SMTP authentication
$mail->Username = '*****[e-mail]';  // SMTP username
$mail->Password = 'ma****02';    // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 465; // TCP port to connect to
$mail->setFrom('ravi******@gmail.com', 'Mailer'); // Add set from id
$mail->addAddress('[e-mail]', 'Ravi Hirani');     // Add a recipient
//$mail->addAddress('[e-mail]');               // Name is optional
//$mail->addReplyTo('[e-mail]', 'Information');
//$mail->addCC('[e-mail]');
//$mail->addBCC('[e-mail]');
//$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
//$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
//$mail->isHTML(true);   // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

Answer 2

请关闭不太安全的应用程序，然后尝试对此行进行评论

//$mail-

我希望它能起作用！

Answer 3

错误消息非常清楚“无法验证”。我想说你正确地使用了PHPMailer类，只是没有填写正确的gmail帐户详细信息。

我想在你的问题中，用户名和密码字段看起来像

$mail->Username = "@gmail.com";
$mail->Password = "";

很明显，因为你不想分享它们，我建议你在问题中这样介绍它们

$mail->Username = "********@gmail.com";
$mail->Password = "********";

因此如果您使用正确的用户名和密码还有其他两件事要检查

>

如果启用了该选项，您的gmail帐户中可能启用了两步验证。如果是这种情况，您需要创建特定于应用程序的密码。
