PHP中的MIME多部分消息未发送答案

【问题标题】：MIME Multipart Message in PHP not sendingPHP中的MIME多部分消息未发送

【问题描述】：

我正在尝试在 PHP 中发送 MIME 多部分消息，但它没有发送。我得出的结论是，这可能是因为某处的 MIME 语法有问题，但我不知道在哪里。

代码如下：

$Subject = "****** Contact Form";
$Name = trim(stripslashes($_POST['Name'])); 
$Email = trim(stripslashes($_POST['Email'])); 
$Message = nl2br(trim(stripslashes($_POST['Message'])));
$MessagePlain = trim(stripslashes($_POST['Message']));
$ReferredBy = $_POST['referredby']; 
$Other = trim(stripslashes($_POST['othertext'])); 
$Day = $_POST['Day']; 
$Month = $_POST['month']; 
$Year = $_POST['year']; 

if ($Month = 1) {
        $Month = 'January';
    } elseif ($Month = 2) {
        $Month = 'February';
    } elseif ($Month = 3) {
        $Month = 'March';
    } elseif ($Month = 4) {
        $Month = 'April';
    } elseif ($Month = 5) {
        $Month = 'May';
    } elseif ($Month = 6) {
        $Month = 'June';
    } elseif ($Month = 7) {
        $Month = 'July';
    } elseif ($Month = 8) {
        $Month = 'August';
    } elseif ($Month = 9) {
        $Month = 'September';
    } elseif ($Month = 10) {
        $Month = 'October';
    } elseif ($Month = 11) {
        $Month = 'November';
    } elseif ($Month = 12) {
        $Month = 'December';
}

$MIMEBoundary = md5(uniqid(rand()));

// prepare email headers
$Headers  = "MIME-Version: 1.0\r\n";
$Headers .= "From: ******\r\n";
$Headers .= "Reply-To: ****** <******@hotmail.com>\r\n";
$Headers .= "Content-type: multipart/alternative; boundary=$MIMEBoundary\r\n";

// prepare email body text
$Body = "--" . $MIMEBoundary . "\r\n";
$Body .= "Content-type: text/html;charset=\"ISO-8859-1\"\r\n";
$Body .= "Content-Transfer-Encoding: base64\r\n\r\n";

问题

你的代码有几个问题：

第一个和第二个正文部分之间的分隔符不正确

$Body .= "\r\n\r\n--' . $MIMEBoundary . '\r\n";

上面的行将输出单引号和点。它应该是：

  $Body .= "\r\n\r\n--" . $MIMEBoundary . "\r\n";

或

  $Body .= "\r\n\r\n--$MIMEBoundary\r\n";

两封电子邮件中的关闭分隔符都不正确

$Body .= "\r\n\r\n--" . $MIMEBoundary;
$Body2 .= "\r\n\r\n--" . $MIMEBoundary;

关闭分隔符必须以两个破折号结尾，因此上面的行应为：

  $Body .= "\r\n\r\n--" . $MIMEBoundary . "--";
  $Body2 .= "\r\n\r\n--" . $MIMEBoundary . "--";

或

  $Body .= "\r\n\r\n--$MIMEBoundary--";
  $Body2 .= "\r\n\r\n--$MIMEBoundary--";

内容编码不正确

如果您指定Content-Transfer-Encoding: base64，您还必须指定base64_encode()（和chunk_split()）该正文部分。

另请参阅下面的最后说明。

MIME 语法

这是根据 RFC 2046 的多部分消息正文结构的摘录。（BNF 语法，有些简化。）

multipart-body := [序言 CRLF] 虚线边界CRLF 身体部分 *封装闭合分隔符 [CRLF 结语] dash-boundary := "--" 边界 body-part := MIME-part-headers [CRLF *OCTET] 封装 := 分隔符 CRLF 身体部位 delimiter := CRLF 破折号边界 close-delimiter := 分隔符“--”

参考文献

最后说明

在 HTML 电子邮件正文中展开的变量（例如 $Name 等）应使用 htmlspecialchars() 进行转义。

如果将每个正文部分存储在变量中，则更容易理解电子邮件的结构：

  $Body  = "--$MIMEBoundary\r\n"; /* First dash-boundary */
  $Body .= "Content-type: text/html;charset=\"ISO-8859-1\"\r\n";
  $Body .= "Content-Transfer-Encoding: base64\r\n";
  $Body .= "\r\n";
  $Body .= $Body_part1;
  $Body .= "\r\n--$MIMEBoundary\r\n"; /* delimiter */
  $Body .= "Content-type: text/plain;charset=\"ISO-8859-1\"\r\n";
  $Body .= "Content-Transfer-Encoding: base64\r\n";
  $Body .= "\r\n";
  $Body .= $Body_part2;
  $Body .= "\r\n--$MIMEBoundary--"; /* close-delimiter */
  /* You only need a single CRLF between body part and delimiter. */

就个人而言，我会在使用之前测试 MIME 边界字符串是否出现在任何身体部位，但我也会使用 much 更短的边界字符串。但这只是我。普通人不会那样做。
