PHPMailer 用 PHP 發信 & Gmail 申請應用程式密碼

在 github 上面有一個 PHPMailer 專案，他號稱是目前世界上最潮的 PHP send mail code production，對於編碼的支援度也很好，最重要的是他支援各種驗證機制，這讓很多目前五花八門的驗證方式相容性就提高了許多

在此篇簡單紀錄如何使用 PHPMailer

Step.1 複製 PHPMailer 專案

$ git clone https://github.com/PHPMailer/PHPMailer

 

Step.2 建立單封郵件測試

$ cd PHPMailer 
 $ sendmail.php 
  
 <?php 
 require 'PHPMailerAutoload.php'; 
  
 $mail = new PHPMailer; 
  
 // Enable verbose debug output 
 //$mail->SMTPDebug = 3;                                
  
 // Set mailer to use SMTP 
 $mail->isSMTP(); 
  
 // smtp 伺服器, 支援多台smtp server備援 
 $mail->Host = 'smtp1.gmail.com'; 
  
 // Enable SMTP authentication 
 $mail->SMTPAuth = true; 
  
 // SMTP username 
 $mail->Username = 'user@example.com'; 
  
 // SMTP password , If you must use the gmail application password 
 $mail->Password = 'secret'; 
  
 // Enable TLS encryption, `ssl` also accepted 
 $mail->SMTPSecure = 'tls'; 
  
 // TCP port to connect to 
 $mail->Port = 587; 
  
 $mail->setFrom('from@example.com', 'Mailer'); 
  
 // Add a recipient , name is optional 
 $mail->addAddress('joe@example.net', 'Joe User'); 
 $mail->addAddress('ellen@example.com'); 
  
 // Add a recipient ,  
 $mail->addReplyTo('info@example.com', 'Information'); 
 $mail->addCC('cc@example.com'); 
 $mail->addBCC('bcc@example.com'); 
  
 // Add attachments , optional name 
 $mail->addAttachment('/var/tmp/file.tar.gz'); 
 $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); 
  
 // Set email format to HTML 
 $mail->isHTML(true); 
  
 $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'; 
  
 if(!$mail->send()) { 
     echo 'Message could not be sent.'; 
     echo 'Mailer Error: ' . $mail->ErrorInfo; 
 } else { 
     echo 'Message has been sent'; 
 }

 

如果你使用的是 Gmail smtp，那 Password 的部分如果你使用的是 "網頁登入的密碼" 就會被 Gmail 阻擋顯示錯誤訊息『Please log in via your web browser and then try again.』，並且要求使用 application password

 

 

申請 Gmail Application Password

登入你的 Gmail 到以下找到應用程式密碼進行新增，Gmail 會提供一組密碼給你作應用程式驗證使用。

https://myaccount.google.com/u/0/security



將密碼代入 send.php 中的 $mail->Password 就可以驗證成功！
