Mandril：如何将 ics 邀请文件附加到模板？

Question

你好，

我想知道 mandrill 是否支持发送带有附加 ics 文件的邮件。

假设我有一些模板。

function sendMailMandrillInvite($name, $contact_email, $textarea, $url, $template_name = 'invite-businesses'){
    $merge = 'true';
    $message = array('dest_mail' => $contact_email, 'merge' => $merge);

    $message['to'] = array(array('email' => $contact_email));

    $mergeVars[] = array(
         'rcpt' => $contact_email,
                     'vars' => array(
                      array('name' => 'contact_name', 'content' => $name),
                      array('name' => 'message', 'content' => $textarea),
                      array('name' => 'url', 'content' => $url)
                    )
                  );

         $template_content = array(array('name' => 'example name', 'content' => 'example content')); // dummy usage
         $message['merge_vars'] = $mergeVars;

        return $this->messages_send_template($template_name, $template_content, $message);
    }

创建模板（HTML）并附加ics文件以使山魈邮件成为“邀请”的方法是什么？

有可能吗？

谢谢，

目前，我们无法支持文本/日历多部分格式，这通常是用于在电子邮件中添加这些活动邀请的格式。当 Mandrill 的解析器遇到这些类型的消息部分（文本/日历）时，它将跳过它们，因为它们不符合它知道如何抽象掉的任何内容。它不是真正的文本或 HTML、附件或嵌入图像。将来，我们将考虑为这种特殊形式的消息添加特殊支持，因为它非常流行，但我无法提供任何具体的预计到达时间。同时，您可以考虑生成 .ics 文件并附加它们，就像您通过 Mandrill API 或 SMTP 集成处理其他类型的附件一样。

所以这是我使用的一种方式：

模板

{
    "key": "xxxxxxxxxxxxxxxxxx",
   "template_name": "fess1",
    "template_content": [
        {
            "name": "example name",
            "content": "example content"
        }
    ],
    "message": {
        "merge": "true",        
        "to": [
            {
                "email": "snaggs@gmail.com",
                "name": "Snaggs",
                "type": "to"
            }
        ],
        "headers": {
            "Reply-To": "snaggs@gmail.com",
            "MIME-Version": 1.0                
        },        
        "merge": true,
        "merge_vars": [
            {
                "rcpt": "snaggs@gmail.com",
                "vars": [
                    {
                        "name": "FNAME",
                        "content": "Snaggis"
                    }
                ]
            }
        ],
        "attachments": [

你应该使用https://icalendar.readthedocs.io/en/latest/index.html生成简单的ics文件，用https://docs.python.org/2/library/base64.html#base64.b64decode将其转换为base64并作为附件发送

[
  {
    'type': "text/calendar",
    'content': b64encode(
            make_isc_calendar(start, end, location, event)),
    'name': "calendar.ics",
  }
]
