启用Sendgrid的订阅跟踪

Question

这实际上是这个问题的扩展

但是我的代码发生了一点变化，所以我想我应该开始一个新的问题。我正在使用SMTP-API来加快服务器和Sendgrid之间的传递。

$hdr = new SmtpApiHeader();
$toList = $mailTo;
$hdr->addTo($toList);
$hdr->addFilterSetting('subscriptiontrack', 'enable', 1);

$to = array('email@email.edu'=>'Carey Estes');
$transport = $connection = Swift_SmtpTransport::newInstance('smtp.sendgrid.net', 465, 'ssl');
$transport ->setUsername($username);
$transport ->setPassword($password);
$swift = Swift_Mailer::newInstance($transport);

$message = new Swift_Message($subject);

$headers = $message->getHeaders();
$headers->addTextHeader('X-SMTPAPI', $hdr->asJSON());

$message->setFrom($mailFrom);
$message->setBody($contents, 'text/html');
$message->setTo($to);

if ($recipients = $swift->send($message, $failures))
{
    return true;
}

类似于我以前的问题，我不能操纵电子邮件中的取消订阅链接。以前，我不能用新的设置打开它off...and，我似乎不能打开它。

$hdr->addFilterSetting('subscriptiontrack', 'enable', 1);

是否应使取消订阅链接在电子邮件中可用？无论是0还是1，取消订阅链接都不会出现。

在前面的问题中，我错误地构造了标题中的JSON。现在是这样了吗？

更新

下面是一个var_dump的$header变量，在我看来是错误的：

下面是SmtpApiHeader类：

<?php 

class SmtpApiHeader
{
    var $data;

    function addTo($tos)
    {
        if (!isset($this->data['to'])) {
            $this->data['to'] = array();
        }
        $this->data['to'] = array_merge($this->data['to'], (array) $tos);
    }

    function addSubVal($var, $val)
    {
        if (!isset($this->data['sub'])) {
            $this->data['sub'] = array();
        }

        if (!isset($this->data['sub'][$var])) {
            $this->data['sub'][$var] = array();
        }
        $this->data['sub'][$var] = array_merge($this->data['sub'][$var], (array) $val);
    }

    function setUniqueArgs($val)
    {
        if (!is_array($val))
            return;
        // checking for associative array
        $diff = array_diff_assoc($val, array_values($val));
        if (((empty($diff)) ? false : true)) {
            $this->data['unique_args'] = $val;
        }
    }

    function setCategory($cat)
    {
        $this->data['category'] = $cat;
    }

    function addFilterSetting($filter, $setting, $value)
    {

    function asJSON()

        $json = json_encode($this->data);
        // Add spaces so that the field can be folded
        $json = preg_replace('/(["\]}])([,:])(["\[{])/', '$1$2 $3', $json);
        return $json;
    }

    function as_string()
    {
        $json = $this->asJSON();
        $str  = "X-SMTPAPI: " . wordwrap($json, 76, "\n ");
        return $str;
    }

}

我得到了这里

更新28.8.13

如果我按照Nick的建议，删除hdr调用并运行以下命令：

$headers->addTextHeader('X-Test', 'Some Text'); 
                echo $headers->toString();

那我就明白了：

消息-ID：1377710372.521e3124a5c6c@localhost日期: Wed，2013年8月28日13:19:32-0400主题:测试，更多信息来自:MIME-版本: 1.0内容-类型:文本/纯文本；charset=utf-8内容-传输-编码:引用-可打印X-测试:一些文本

问题似乎与SmtpApiHeader类有关，但它只是来自Sendgrid文档的一个副本。真奇怪。

更新30.8.13

我得到了Sendgrid php库 (在上一个问题中，斯威夫特的评论)使这个工作正常。似乎是处理延迟和添加过滤器的最佳方法。将其纳入Symfony 1.4是有点棘手的，但是周五的测试显示，速度和一致性都有了显著提高。
