Google SMTP错误：无法验证

Question

一旦我把它放在服务器上，我有类似的代码工作在我的本地环境，它的作品完美，任何想法下面的代码不工作？

编辑：我没有把我的Gmail设置为“不太安全”

<?php 
$setid = $_POST['setid']; 
$promo = $_POST['promo']; 


echo "Good Sir, your set ID is ".$setid.", and you are eligible for the following deal:"; 
echo "<br><br>"; 
echo $promo; 

$message= "Good Sir, your set ID is ".$setid.", and you are eligible for the following deal:"."<br><br>".$promo; 

    require "phpmailer/class.phpmailer.php"; 

    // Instantiate Class 
    $mail = new PHPMailer(); 

    // Set up SMTP 
    $mail->IsSMTP();    
    $mail->SMTPAuth = true;   
    $mail->SMTPSecure = "ssl"; 
    $mail->Host = "smtp.gmail.com"; 
    $mail->Port = 465; 
    $mail->Encoding = '7bit'; 

    // Authentication 
    $mail->Username = "xxx@example.com"; 
    $mail->Password = "mypass"; 

    // Compose 
    $mail->SetFrom("jghh@ghh.ca"); 
    $mail->AddReplyTo("ghh@ghh.ca"); 
    $mail->Subject = "TryIt"; 
    $mail->MsgHTML($message); 

    // Send To 
    $mail->AddAddress("receiver@hotmail.com", "Recipient Name"); 
    $result = $mail->Send(); 
    $message = $result ? 'Successfully Sent!' : 'Sending Failed!';  

    unset($mail);

你可能需要启用less secure apps

Change account access for less secure apps

To help keep Google Apps users' accounts secure, we may block less secure apps from accessing Google Apps accounts. As a Google Apps user, you will see a "Password incorrect" error when trying to sign in. If this is the case, you have two options:

1. Option 1: Upgrade to a more secure app that uses the most up to date security measures. All Google products, like Gmail, use the latest security measures.

2. Option 2: Change your settings to allow less secure apps to access your account. We don't recommend this option because it might make it easier for someone to break into your account. If you want to allow access anyway, follow these steps:

   2.1. Go to the " Less secure apps " section in My Account

   2.2. Next to "Access for less secure apps," select Turn on. (Note to Google Apps users: This setting is hidden if your administrator has locked less secure app account access.)

If you still can't sign in to your account, the " password incorrect " error might be caused by a different reason.

UPDATE：

添加错误的文件的顶部报告（S）在您打开PHP标签之后看到的PHPMailer

$mail->SMTPDebug = 1; // enables SMTP debug information (for testing) 
         // 1 = errors and messages 
         // 2 = messages only 

mple <?php error_reporting(E_ALL); ini_set('display_errors', 1);

，并启用调试，如果它得到任何东西。
