您好我使用php邮件程序Swiftmailer使用SMTP API通过SendGrid发送。我们可以将唯一参数传递给SendGrid以帮助跟踪电子邮件。我已成功通过Swiftmailer传递唯一标头:
$headers = $message->getHeaders();
$args = ' {
"customerAccountNumber": "55555",
"activationAttempt": "1",
"New Argument 1": "New Value 1",
"New Argument 2": "New Value 2",
"New Argument 3": "New Value 3",
"New Argument 4": "New Value 4"
}';
$headers->addTextHeader('unique_args', $args);
虽然这些值已成功注入已发送电子邮件的标题中,但它们不会被SendGrid传回我的事件webhook或控制面板中。
我也试过这个,但是没有用:
{
"query" : "sample",
"search_engine" : "google" //can be anything else such as bing or etc.
}
这可能是SendGrid支持的一个问题,但由于它与Swiftmailer有关,我想我先试试这里。谢谢!

方法addTextHeader用于一个值
$headers->addTextHeader('unique_args', $args);
您应该使用addParameterizedHeader方法,而不是像这样
$headers->addParameterizedHeader(
["customerAccountNumber" => "55555"],
["activationAttempt" => "1"]
);

SendGrid expects a JSON key/value structure in the X-SMTPAPI
header entry
我有一个使用SwiftMailer 5.0.3的旧项目。这是我将类别值发送到SendGrid的方式:
$message->getHeaders()->addTextHeader('X-SMTPAPI', json_encode(array(
'category' => $category,
)));
将该模式应用于您的示例:
$headers = $message->getHeaders();
$args = array(
'unique_args' => array(
'AccountId' => $accountId,
"customerAccountNumber" => "55555",
"activationAttempt" => "1",
"New Argument 1" => "New Value 1",
"New Argument 2" => "New Value 2",
"New Argument 3" => "New Value 3",
"New Argument 4" => "New Value 4",
),
);
$headers->addTextHeader('X-SMTPAPI', json_encode($args));
