使用gmail无法使用php发送电子邮件 - 授权错误

Question

我是PHP新手，尝试使用注册表单构建网站。用户应该收到一封带有确认链接的电子邮件（因为我有一个免费的托管服务器，我正尝试使用Gmail服务器）。事情是我正在努力与电子邮件的PHP代码。我试图用PHPMailer的功能如下：

<?php 
 
/** 
 
* This example shows settings to use when sending via Google's Gmail servers. 
 
*/ 
 

 
//SMTP needs accurate times, and the PHP time zone MUST be set 
 
//This should be done in your php.ini, but this is how to do it if you don't have access to that 
 
date_default_timezone_set('Etc/UTC'); 
 
require 'PHPMailer/PHPMailerAutoload.php'; 
 

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

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

 
//Enable SMTP debugging 
 
// 0 = off (for production use) 
 
// 1 = client messages 
 
// 2 = client and server messages 
 
$mail->SMTPDebug = 2; 
 

 
//Ask for HTML-friendly debug output 
 
$mail->Debugoutput = 'html'; 
 

 
//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 system to use - ssl (deprecated) or tls 
 
$mail->SMTPSecure = 'tls'; 
 

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

 
//Username to use for SMTP authentication - use full email address for gmail 
 
$mail->Username = "MYEMAIL@gmail.com"; 
 

 
//Password to use for SMTP authentication 
 
$mail->Password = "MYPASSWORD"; 
 

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

 
//Set an alternative reply-to address 
 
$mail->addReplyTo('example@example.com', 'Name S'); 
 

 
//Set who the message is to be sent to 
 
$mail->addAddress('email@gmail.com', 'John Doe'); 
 

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

 
//Read an HTML message body from an external file, convert referenced images to embedded, 
 
//convert HTML into a basic plain-text alternative body 
 
$mail->msgHTML("HELLo"); 
 

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

 
//send the message, check for errors 
 
if (!$mail->send()) { 
 
    echo "Mailer Error: " . $mail->ErrorInfo; 
 
} else { 
 
    echo "Message sent!"; 
 
} 
 
?>

我试过两个端口587和465也试过SSL和TLS。每次我尝试运行代码我得到以下错误：

另外，我收到一封电子邮件来自Gmail的主题为“有人取得了您的密码”。我打开电子邮件，发现这个“
嗨Manny， 有人刚刚使用您的密码尝试使用应用程序（例如电子邮件客户端或移动设备）登录您的Google帐户MYEMAIL@gmail.com。 我在运行php页面后约15分钟收到此电子邮件。

我关闭了“两步验证”并关闭了“允许安全性较低的应用程序”。似乎没有任何帮助。任何人都可以帮助我吗？

去年我有同样的问题：代码（VB.Net）是好的，所以在哪里凭据。问题在于，gmail不喜欢远程（我的托管）的Web服务器中的某个应用程序，它试图使用相同的用户名。 （使用远程桌面）在Gmail

• 记录一次从该服务器：

  我固定它（在两个不同的场合）由。

• 从我的电脑登录https://accounts.google.com/DisplayUnlockCaptcha到“解锁”远程连接。

之后，再次测试您的代码。
