Question

我试图发送使用的PHPMailer和下面的代码的电子邮件，但我得到这个错误：

2017-10-10 17:39:33 SMTP ERROR: Failed to connect to server: php_network_getaddresses: getaddrinfo failed: Name or service not known (0) 2017-10-10 17:39:33 SMTP ERROR: Failed to connect to server: php_network_getaddresses: getaddrinfo failed: Name or service not known (0) SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting Message could not be sent.Mailer Error: SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshootingfas

use PHPMailer\PHPMailer\PHPMailer; 
    use PHPMailer\PHPMailer\Exception; 

    require 'vendor/autoload.php'; 

    $mail = new PHPMailer(true);        // Passing `true` enables exceptions 
try { 
    //Server settings 
    $mail->SMTPDebug = 2;         // Enable verbose debug output 
    $mail->isSMTP();          // Set mailer to use SMTP 
    $mail->Host = 'smtp1.example.com;smtp2.example.com'; // Specify main and backup SMTP servers 
    $mail->SMTPAuth = true;        // Enable SMTP authentication 
    $mail->Username = 'myaccount@gmail.com';     // SMTP username 
    $mail->Password = '*********';       // SMTP password 
    $mail->SMTPSecure = 'tls';       // Enable TLS encryption, `ssl` also accepted 
    $mail->Port = 587;         // TCP port to connect to 

    //Recipients 
    $mail->setFrom('from@example.com', 'Mailer'); 
    $mail->addAddress('joe@example.net', 'Joe User');  // Add a recipient 
    $mail->addAddress('ellen@example.com');    // Name is optional 
    $mail->addReplyTo('info@example.com', 'Information'); 
    $mail->addCC('cc@example.com'); 
    $mail->addBCC('bcc@example.com'); 

    //Attachments 



    //Content 
    $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'; 

    $mail->send(); 
    echo 'Message has been sent'; 
    } catch (Exception $e) { 
     echo 'Message could not be sent.'; 
     echo 'Mailer Error: ' . $mail->ErrorInfo; 
    }

你意识到这是使用占位符数据的实例？ example.*域是guaranteed not to exist，具体而言，使他们能够安全地示例代码和文档中使用。您需要替换自己的域为所有那些例如地址，然后DNS查找就可以了（这一点正是目前没有你）。
