Question

Answer 1

下面是我如何使用 Sendgrid 通过 PHP 从 EC2 实例发送邮件:

1. 注册一个 Sendgrid 帐户。您将收到用于发送电子邮件的用户名和密码。此外，Sendgrid 将手动验证您的帐户(可能是为了防止垃圾邮件)。
2. 在 ubuntu 中安装 PHP curl 库:sudo apt-get install php5-curl。

3. 使用此 PHP 代码发送电子邮件:

   $url = 'http://sendgrid.com/';
   $user = 'sendgrid_user';
   $pass = 'sendgrid_password'; 
   
   $params = array(
       'api_user'  => $user,
       'api_key'   => $pass,
       'to'        => $dest_addr,
       'subject'   => $subject,
       'html'      => $body,
       //'text'      => 'testing body',
       'from'      => $from_addr,
     );
   
   $request =  $url.'api/mail.send.json';
   
   $session = curl_init($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);
   
   //If the result is {"message":"success"}, then the mail is sent.  
   curl_close($session);
