Sendgrid x-smtpapi错误与'缺少目标电子邮件'

Question

我已经设置了以下内容:

error_reporting(E_ALL | E_NOTICE);
ini_set('display_errors', '1');

$file = date('YmdHis');
$fp = fopen('/var/www/mydir/files/'.$file.'.csv', 'w');

$url = 'http://sendgrid.com/';
$user = 'myuser';
$pass = 'mypass';
$to_emails = array(
  'to' => array(
    '1@example.com','2@example.com','3@example.com'
  ),
  'category' => 'Test'
);

$fileName = $file;
$filePath = dirname(__FILE__);

$params = array(
    'api_user'  => $user,
    'api_key'   => $pass,
    'x-smtpapi' => json_encode($to_emails),
    //'to' => 'example@example.com',
    'subject'   => 'Test email',
    'html'      => '<p>Testing sendgrid mail</p>',
    'text'      => 'sent',
    'from'      => 'me@example.com',
    'files['.$file.'.csv]' => '@'.$filePath.'/files/'.$fileName.'.csv'
  );

print_r($params);

$request =  $url.'api/mail.send.json';

// Generate curl request
$session = curl_init($request);

// Tell curl to use HTTP POST
curl_setopt ($session, CURLOPT_POST, true);

// Tell curl that this is the body of the POST
curl_setopt ($session, CURLOPT_POSTFIELDS, $params);

// Tell curl not to return headers, but do return the response
curl_setopt($session, CURLOPT_HEADER, false);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);

// obtain response
$response = curl_exec($session);
curl_close($session);

print_r($response);

//unlink('./files/'.$file.'.csv');

mysql_close($connect);

问题是,它不会发送到我的受者$to_emails阵列和输出阵列中的'价值"缺少目标电子邮件"这确实输出我通过电子邮件的阵列,但它仍然是寻找.’ -我我想知道为什么以及如何解决这个问题？据我所知,我已经密切关注了Sendgrid文档 - https://sendgrid.com/docs/Code_Examples/php.html.

如果我取消注释'to'行,它会将电子邮件发送到example@example.com就好了.

即使使用该to参数,目前也始终需要该参数.我们建议将其设置为地址.如果存在,API将忽略常规参数.SMTPAPI tofromSMTPAPI toto

您链接的示例显示了当前和状态的参数to和x-smtpapi参数

...电子邮件将发送到example1@sendgrid.com和example2@sendgrid.com.正常地址example3@sendgrid.com将不会收到电子邮件.
