网络响应 200，但收到错误消息； PHP 发送电子邮件脚本

Question

我在某个地方得到了这个 PHP 代码，一切看起来都还不错，但是每次我尝试发送测试电子邮件时都会收到一条错误消息；但是，网络消息说它确实发送了。请参阅图像和代码 sn-ps。请帮忙。谢谢

PHP 脚本

    session_cache_limiter( 'nocache' );
    header( 'Expires: ' . gmdate( 'r', 0 ) );
    header( 'Content-type: application/json' );

    $to         = 'myemail@gmail.com';  // put your email here

    $email_template = 'simple.html';

    $subject    = strip_tags($_POST['subject']);
    $email       = strip_tags($_POST['email']);
    $phone      = strip_tags($_POST['phone']);
    $name       = strip_tags($_POST['name']);
    $message    = nl2br( htmlspecialchars($_POST['message'], ENT_QUOTES) );
    $result     = array();


    if(empty($name)){

        $result = array( 'response' => 'error', 'empty'=>'name', 'message'=>'<strong>Error!</strong>&nbsp; Name is empty.' );
        echo json_encode($result );
        die;
    } 

    if(empty($email)){

        $result = array( 'response' => 'error', 'empty'=>'email', 'message'=>'<strong>Error!</strong>&nbsp; Email is empty.' );
        echo json_encode($result );
        die;
    } 

    if(empty($message)){

         $result = array( 'response' => 'error', 'empty'=>'message', 'message'=>'<strong>Error!</strong>&nbsp; Message body is empty.' );
         echo json_encode($result );
         die;
    }



    $headers  = "From: " . $name . ' <' . $email . '>' . "\r\n";
    $headers .= "Reply-To: ". $email . "\r\n";
    $headers .= "MIME-Version: 1.0\r\n";
    $headers .= "Content-Type: text/html; charset=UTF-8\r\n";


    $templateTags =  array(
        '{{subject}}' => $subject,
        '{{email}}'=>$email,
        '{{phone}}'=>$phone,
        '{{name}}'=>$name,
        '{{message}}'=>$message
        );


    $templateContents = file_get_contents( dirname(__FILE__) . '/email-templates/'.$email_template);

    $contents =  strtr($templateContents, $templateTags);

    if ( mail( $to, $subject, $contents, $headers ) ) {
        $result = array( 'response' => 'success', 'message'=>'<strong>Thank You!</strong>&nbsp; Your email has been delivered.' );
    } else {
        $result = array( 'response' => 'error', 'message'=>'<strong>Error!</strong>&nbsp; Cann\'t Send Mail.'  );
}


    echo json_encode( $result );

    die;

HTML FORM - 这是我的 HTML 代码。我的表格可能有问题吗？但是我认为它是 PHP，或者不匹配的东西。

任何有线索的人可能出了什么问题？

Answer 1

您的脚本响应 HTTP 200，错误导致邮件功能不成功。 尝试替换行：

$result = array( 'response' => 'error', 'message'=>'<strong>Error!</strong>&nbsp; Cann\'t Send Mail.'  );

与：

$result = array( 'response' => 'error', 'message'=>'<strong>Error!</strong>&nbsp; Cann\'t Send Mail.', 'reason' => error_get_last()['message'] );

添加到数组中，会显示什么错误

'reason' => error_get_last()['message']

你会看到为什么你的邮件没有发送。

希望对你有帮助:)

Answer 2

您收到 200 错误的原因是您自己捕获了错误并回显了输出。如果您希望错误为 500，可以尝试在错误中添加此 if/else:

header($_SERVER["SERVER_PROTOCOL"] . ' 500 Internal Server Error', true, 500);  
exit;

为了调试邮件功能本身的错误，这篇文章解释了：

$success = mail('example@example.com', 'My Subject', $message);
if (!$success) {
    $errorMessage = error_get_last()['message'];
}

How can I get the error message for the mail() function?
