SMTPError:密码命令失败 PHPMailer [英] SMTPError: Password command Failed PHPMailer
问题描述
要求是提交表单时必须将邮件发送到指定的电子邮件地址.为此，我使用 PHPMailer.
当我第一次从本地主机运行代码时，我收到了在 Gmail 中收到的关键安全警报，我通过打开允许不太安全的应用程序"解决了这个问题检查并批准了安全事件.
现在代码在由 xampp 提供支持的本地主机中完美运行，但不能在共享主机中运行.当我点击共享主机中表单页面中的提交按钮时，我收到以下消息:
The Requirement is that when the form is submitted the mail has to be sent the specified email address. For this I am using PHPMailer.
When I ran the code first time from localhost, I received Critical Security Alert received in Gmail, which I resolved by turning on "Allow Less Secure Apps" and also
checked and approved the security event.
Now the code works perfectly in localhost powered by xampp but not in shared hosting. When I hit the submit button in the Form page present in shared hosting, I get the following message:

发送邮件的 PHPMailer 代码如下:
The PHPMailer code for sending mail follows:
try {
//Server settings
$mail->SMTPDebug = SMTP::DEBUG_SERVER; // Enable verbose debug output
$mail->isSMTP(); // Send using SMTP
$mail->Host = 'smtp.gmail.com'; // Set the SMTP server to send through
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->isHTML();
$mail->Username = 'username@gmail.com'; // SMTP username
$mail->Password = 'password'; // SMTP password
$mail->SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS; // Enable TLS encryption; `PHPMailer::ENCRYPTION_SMTPS` also accepted
$mail->Port = 587; // TCP port to connect to
//Recipients
$mail->setFrom('username@gmail.com');
$mail->addAddress('username@yahoo.com'); // Add a recipient
// Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Mail subject';
$mail->Body = 'Mail Body';
$mail->send();
echo 'done';
} catch (Exception $e) {
echo "Mailer";
}
已采取以下措施:
The following actions have been taken:
用户名和密码组合正确且未过期.通过 Web 登录并从服务器发送邮件来手动验证本地主机.
Username and Password combination is correct and is not expired. Verified manually by logging via web and also sending mails from the localhost.
$mail->SMTPAuth=false 不能设置，因为多数的共享托管服务提供商似乎出于安全考虑禁用了此功能原因(主要是为了避免垃圾邮件和发送未经请求的电子邮件)
$mail->SMTPAuth=false cannot be set because majority of shared hosting providers seems to have disabled this for security reasons (mainly to avoid spamming and sending of unsolicited emails)
推荐答案
好吧，经过长时间的战斗，我设法解决了这个问题.我从以下 URL 激活了 DisplayUnlockCaptcha:https://accounts.google.com/b/0/DisplayUnlockCaptcha
Well, after a long battle I somehow managed to solve this. I activated DisplayUnlockCaptcha from the following URL: https://accounts.google.com/b/0/DisplayUnlockCaptcha
可能是因为 Gmail 可能将从位于托管服务器中的 PHP 文件接收的登录信息视为不受信任的请求.这是因为托管服务器可能位于不同的地方或国家/地区，并且收到的登录身份验证请求会与 Gmail 帐户经常登录的请求不同.所以作为安全措施，它会在后台使用一些验证码机制(无法查看)
Probably because Gmail might have viewed the logins received from PHP file lying in hosting server as untrusted requests. This is because the hosting servers may reside in different places or countries and the login authentication request received would appear different other than the one from where the Gmail account is logged in frequently. So as a security measure, it would have use some captcha mechanism in the background (which which cannot be viewed)
