使用GMAIL的PHP​​Mailer错误：Mailer错误：SMTP connect（）

Question

I tried to send email from my localhost using my gmail account. I also tried to find answers in the web and even in this website but nothing helped me. I am using XAMPP.

This is the code:

require 'PHPMailer-master/PHPMailerAutoload.php';

$mail = new PHPMailer();         // create a new object
$mail->IsSMTP();                 // enable SMTP
$mail->SMTPDebug = 2;            // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true;          // authentication enabled
$mail->SMTPSecure = 'ssl';       // secure transfer enabled REQUIRED for Gmail
$mail->Host = "smtp.gmail.com";
$mail->Port = 465;               // or 587
$mail->IsHTML(true);
$mail->Username = "myUser@gmail.com";
$mail->Password = "myUserPass";
$mail->SetFrom("myUser@gmail.com");
$mail->Subject = "Test";
$mail->Body = "hello";
$mail->AddAddress("OtherUser@gmail.com");

if(!$mail->Send()) {
    echo "Mailer Error: " . $mail->ErrorInfo;
} else {
    echo "Message has been sent";
}

The full error which I got:

I tried to delete that:

$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail

Or changing the port to 25/587 but it did not help. Does someone know how to fix that?

Answer 1

Assuming that your username and password entered is correct, you need to authorize the external application use of gmail.

Follow the next steps and authorize to make it:

1. First, go to your Google Account Management page
2. Under the Connected apps & sites , click Allow less secure apps: ON

In case it does not work, if your gmail account has 2-step verification enabled, use an auto-generated password .

Update:

Although turning Allow less secure apps: ON might solve your problem, it should be taken as a troubleshooting tip and not as the final solution.

Answer 2

您应该关闭防病毒或防火墙中受电子邮件保护的电子邮件
