PHPMailer錯誤使用GMAIL：郵件錯誤：SMTP連接（）

Question

我試圖從我的本地主機使用我的Gmail帳戶發送電子郵件。 我也嘗試在網上甚至在本網站上找到答案，但沒有任何幫助。我正在使用XAMPP。

這是代碼：

require 'PHPMailer-master/PHPMailerAutoload.php'; 

$mail = new PHPMailer();   // create a new object 
$mail->IsSMTP();     // enable SMTP 
$mail->SMTPDebug = 2;   // debugging: 1 = errors and messages, 2 = messages only 
$mail->SMTPAuth = true;   // authentication enabled 
$mail->SMTPSecure = 'ssl';  // secure transfer enabled REQUIRED for Gmail 
$mail->Host = "smtp.gmail.com"; 
$mail->Port = 465;    // or 587 
$mail->IsHTML(true); 
$mail->Username = "myUser@gmail.com"; 
$mail->Password = "myUserPass"; 
$mail->SetFrom("myUser@gmail.com"); 
$mail->Subject = "Test"; 
$mail->Body = "hello"; 
$mail->AddAddress("OtherUser@gmail.com"); 

if(!$mail->Send()) { 
    echo "Mailer Error: " . $mail->ErrorInfo; 
} else { 
    echo "Message has been sent"; 
} 

完整的錯誤，我得到：

我試圖刪除：

$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail 

或更改端口25/587但它沒有幫助。 有人知道如何解決這個問題嗎？

Answer 1

假設您輸入的用戶名和密碼正確，您需要授權外部應用程序使用gmail。

執行以下步驟，並授權使其：

1. 首先，去你Google Account Management page
2. 下Connected apps & sites，單擊Allow less secure apps: ON

如果它不一樣，如果工作，你的Gmail帳戶啓用了兩步驗證，use an auto-generated password。

更新：

雖然轉向Allow less secure apps: ON可能解決您的問題，它應該被視爲一個故障排除提示，而不是作爲最終的解決方案。
